Features & BenefitsFeatures & Benefits

SummaryThree major benefits separate the Pathfinder chiller from most air-cooled screw chillers:

• Low operating costs with our high and premium efficiency designs

• Very quiet operation allowing for flexible location

• Superior control with the MicroTech III family of controls

Low Operating Costs and High Efficiency Operation

Pathfinder chillers use the McQuay single rotor screw compressor design. Composite gate rotors intermesh with a single rotor and are inherently quieter and more efficient than the older design dual rotor compressors with multiple steel rotors. Large condenser coil surface areas are employed for maximum heat transfer and lower discharge pressures. Advanced technology condenser fans are used to move large volumes of air across the heat exchangers. A single-pass, pure counter-flow, low refrigerant pressure drop, direct-expansion evaporator provides superior performance. Standard Efficiency units all meet ASHRAE 90.1 Standards. High and Premium Efficiency units offer even lower energy costs.

Quiet Operation - Neighborhood Friendly

One of the features that set the Pathfinder chillers apart from other screw chillers is the low operating sound levels at any load point. The quiet operation is the result of single-screw compressor design. The latest McQuay compressor design continues to use a single main rotor with two adjacent rotating composite gaterotors making gas flow velocities and subsequent noise levels among the lowest available. This compressor design is unique and proven by years of excellent service.

Fans are the other sound generator on air-cooled chillers. McQuay utilizes a unique new fan that features a one-piece, molded design and low speed operation. The fan moves large volumes of air at exceptionally low sound levels and is immune to rust, broken rivets and other ills possible with conventional fans. The advanced composite material has been tested to withstand UV light, heat, and humidity corrosion in some of the most severe climates in the world.

Pathfinder chillers are among the quietest air-cooled screw chiller on the market today. Use McQuay's Acoustic Analyzer program to see how this attribute can benefit your project. The chiller sound data is published in this catalog beginning on page 119.

MicroTech III Controls

The MicroTech III unit controller provides an easy to use control environment. The control logic is designed to provide maximum efficiency, to continue operation in unusual operating conditions and to provide a history of unit operation.

Perhaps the greatest control benefit is McQuay's Open Choices™ feature that allows easy interfacing with your BAS of choice using LONWORKS, BACnet, or Modbus communications without costly gateways.

Environmentally Responsible Refrigerant

All Daikin McQuay Pathfinder chillers use R-134a, which has no ozone depletion potential and no phase-out date; a refrigerant for today and the future.

Contributing to LEED® Points

The Pathfinder chiller leads the industry in energy efficiency and responsible refrigerant management. For building owners who wish to pursue Leadership in Energy and Environmental Design (LEED) Green Building Certification, the performance of the Pathfinder chiller can contribute to the following LEED points:

• Energy and Atmosphere Credit 1, Opmtimize Energy Efficiency (1-19 possible points)

• Energy and Atmosphere Credit 4, Enhanced Refrigerant Management (2 points)

Proven Reliability

Full factory testing of every unit ensures trouble-free start-up, reliable operation, and minimizes expensive field repairs.

Excellent Serviceability

Field serviceability has not been sacrificed to meet design performance objectives. Compressors are equipped with combination discharge check and shutoff valves. Suction service valves are available as an option. Compressors and serviceable components such as filter-driers are located on the outside edges of the base allowing ready access.The “W” shaped coil provides excellent headroom under the unit for inspection and service.The MicroTech III controller gives detailed information on the causes of an alarm or fault.

CAT 600-6 5

Features & Benefits

Compressor

A zero clearance fit between the two gaterotors and main screw rotor virtually eliminates leakage between the high and low-pressure sides during compression. Special gaterotor material made from an advanced composite, temperature stable material makes a zero clearance design possible with no detrimental metal-to-metal contact.

The Pathfinder air cooled chiller is equipped with the most advanced means of refrigerant flow control available. An electronic expansion valve coupled with the MicroTech III controller's logic provides excellent operating efficiencies at both full and part load operation.

Modulated stepless unloading matches compressor capacity exactly to the cooling load. The rugged design of the single-screw compressor allows it to be tolerant of liquid slugging. The Pathfinder chiller will start and operate under conditions that would often damage other compressors.

Very low loading enhances the bearing and compressor reliability. Due to symmetrical compression taking place on both sides of the main screw rotor, balanced forces result in the elimination of the radial force loads inherent in twin-screw compressors.

Figure 1: Screw Compressor - balanced forces

Evaporator

Pathfinder units are equipped with a direct expansion evaporator with copper tubes rolled into steel tubesheets. The evaporators are single-pass on both the refrigerant and water sides for pure counter-flow heat exchange and low refrigerant pressure drop. Both attributes contribute to the heat exchanger effectiveness and total unit's outstanding efficiency.

Condenser

The McQuay designed “W”-shaped, 16 fin-per-inch, condenser coil provides the maximum condenser heat transfer per foot of unit length. This translates to a smaller footprint, fewer structural elements and smaller pad size. The fins are slotted to provide even air distribution across and through the coil. Various fin materials and coatings are available for extreme conditions.

115 Volt Convenience Outlet

A 10.0 amp, 115-volt convenience outlet mounted inside the control panel is standard on all 60-Hz units.

Solid State Starters (Standard)

Having solid-state starters as standard on the Pathfinder units takes a giant step forward in compressor protection and sets a standard for the rest of the industry. Our solid-state starters include self-diagnostics, metering and display and include ground fault and phase/voltage protection.

A primary benefit is that the compressors are started slowly, requiring from three to seven seconds to go from a stop to full-speed condition. The smooth, stepless acceleration and controlled slow deceleration, reduces mechanical and electrical stress for even greater compressor/motor life.If liquid refrigerant is present at the compressor, the liquid can usually be pumped out without damage to the compressor. The controlled deceleration reduces shut down stress. Solid state starters offer additional motor protection features and over twenty LED operating and fault messages.

Variable Frequency Drive (VFD) (Option)

The variable frequency drive option is a technology that has been used for decades to control motor speed on a wide variety of motor-drive applications. When applied to screw compressor motors, significant gains in compressor part load efficiency can be realized by reducing motor speed in conjunction with reduced cooling requirements.

The improvement in efficiency and reduction of annual energy costs are maximized when there are long periods of part-load operation and lower ambient temperature conditions. Based on AHRI Standard 550/590, chillers will typically run 99% of the time at part load conditions so energy savings will be seen in most applications.

Figure 2: Comparison of inrush amps during start-up

VFD's also provide benefits on the electrical characteristics of the unit. VFD's provide lower starting current compared to typical starters such that the inrush current does not exceed the full load operating current. This feature can help to reduce electrical installation costs, especially if the chiller is powered from emergency generators. Lower inrush current requirements typically allow the owner to downsize the capacity of the generator.

Features & Benefits

Pathfinder chillers with the VFD option provide a high power factor rating without the use of capacitors. The power factor for high and premium efficiency Pathfinder VFD models is 0.94-0.95 depending on the model size and voltage.

Power Factor Correction Capacitors (Option)

Many local utility companies require high power factor systems to improve power utilization. McQuay is the only major manufacturer to offer Power Factor Correction Capacitors as a standard option on air-cooled screw chillers. These capacitors, when applied to non-vfd units, will improve the power factor to a minimum of 95%. Pathfinder models with VFD naturally feature power factors in this range. The PFCC option provides a great benefit compared to field installed capacitors, and will carry ETL certification and be fully backed by manufacturer’s warranty.

RapidRestore™ & Fast Loading (Option)

Data center and other critical installations often require a fast return to 100% cooling load after a power interruption. McQuay's RapidRestore and Fast Loading option provides a 30-second restart capability. The power interruption must be longer than one second and the Start-to-Start timer timed out.

Wye-Delta Reduced-Voltage Starter (Option)

McQuay also offers the option of wye-delta reduced voltage instead of standard solid state starters. In the “Y” configuration, each set of phase windings is brought together at a common point reducing the current and torque to 33% of full in-rush. Three contactors and a timer are used to switch the six leads brought out of the motor from the Y-connection to the Delta configuration in a two-step starting process.

These starters are useful in reducing the motor's starting inrush and negative effect on the power supply, however they have some disadvantages. They still cause mechanical shock to the compressor between steps, have high contactor maintenance and do not control deceleration.

D-Net™ Performance Service Capable

All Pathfinder Chillers shipped within North America are D-Net Performance Service capable. D-Net, based upon Daikin customer support technology, provides McQuay a direct electronic connection to your Pathfinder chiller, giving McQuay Factory Service the ability to provide an enhanced level of support to keep your system running efficiently and reliably.

CAT 600-6 9

Installation and Application Information

Unit Placement

For roof-mounted applications, the unit must be installed on a steel channel or I-beam frame to support the unit above the roof. Vibration isolators are recommended for all roof-mounted installations or wherever vibration transmission is a consideration. Isolator loads and kit numbers can be found in the Pathfinder Installation Manual on www.mcquay.com.

For ground level applications, the unit must be installed on a substantial base that will not settle. McQuay recommends a one-piece concrete slab with footings extended below the frost line, and the installation engineer should determine its necessity. The foundation must be level within 13 mm (1/2 inch) over its length and width and strong enough to support the unit's operating weight as listed in the Physical Data tables. The addition of neoprene waffle pads (supplied by customer) under the frame allows water to drain from inside the frame, which can act as a dam.

On ground level applications, protection against vandalism is recommended; either by the optional factory-installed lower wire mesh guards or louvers, or by a field installed screening fence. Note that the fence must allow free flow of air to the condenser coil for proper unit operation. Upper wire mesh coil guards are standard.

Ice Mode

Optional double evaporator insulation is recommended for ice mode operation. The standard controller software will require “ice” setpoint changes and a digital signal into the controller is required to change to the ice mode and back to standard cooling. See the Field Wiring Diagram on page 127 for the connection location. In ice mode, the unit will operate at full load until the shutoff temperature setpoint is reached.

Clearances

Air-cooled units require free air flow to and from the condenser coils. Install units per noted installation clearances below and requirements outlined in IM 997 (IM 1002 for 50Hz models) available on www.mcquay.com. There must be no obstructions above the fan discharge that can cause air recirculation. Air restriction and recirculation can cause high-pressure trips and will reduce capacity, efficiency, and compressor life. Do not install ductwork on condenser fans.

Structures, other equipment, fencing, plants, and trees must be considered for air flow interference. Ventilators and any sources of contaminated or heated discharges gases and air will affect system performance. Pit type installation must meet McQuay requirements as outlined on page 12.

Service Access

Compressors, filter-driers, and manual liquid line shutoff valves are accessible on each side or end of the unit. The evaporator heater is located on the barrel.

The control panels are located on the end of the chiller. The left-hand control box contains the unit and circuit

microprocessors as well as transformers, fuses and terminal. The right-hand panel contains a circuit breaker. A minimum of four feet of clearance is required in front of the panels. The side clearance required for airflow provides sufficient service clearance.

On all Pathfinder units, the condenser fans and motors can be removed from the top of the unit. The complete fan/motor assembly can be removed for service. The fan blade must be removed for access to wiring terminals at the top of the motor.

Do not block access to the sides or ends of the unit with piping or conduit. These areas must be open for service access. Do not block access to the control panels with field-mounted disconnect switches.

Figure 6: Control Panel Component Location

Clearance Requirements

Notes:

1 To avoid a performance derate, minimum side clearance between two units is 12 feet (3.7 meters).

2 Unit must not be installed in a pit or enclosure that is deeper or taller than the height of the unit unless extra clearance is provided per note 4.

3 Minimum clearance on each side is 6 feet (1.8 meters) when installed in a pit no deeper than the unit height.

4 Minimum side clearance to a side wall or building taller than the unit height is 4 feet (1.2 meters), provided no

DANGER

Disconnect, lockout and tag all power to the unit before servicing condenser fan motors or compressors. Failure to do so can cause bodily injury or death.

NOTES:1. The Emergency Switch Relay de-energizes circuit #1 and #2 control power when activated,

causing an immediate compressor and fan shutdown. The red emergency button switch is located on the bottom front of the control panel door.

2. The control power transformer is located in the power panel adjacent to the control panel. 3. Additional extension (aka extension) modules are located elsewhere on the chiller.

solid wall above 6 feet (1.8 meters) is closer than 12 feet (3.7 meters) to the opposite side of the unit.

5 Do not mount electrical conduits where they can block service access to compressor controls, refrigerant driers or valves.

6 There must be no obstruction of the fan discharge.

7 Field installed switches must not interfere with service access or airflow.

Figure 7: Clearance Requirements

Restricted Air Flow

General

The clearances required for design operation of Pathfinder air-cooled chillers are described in the previous section. Occasionally, these clearances cannot be maintained due to site restrictions such as units being too close together or a fence or wall restricting airflow, or both. Pathfinder chillers have several features that may help mitigate the penalties attributable to restricted airflow.

"The condenser section is "W" shaped, allowing inlet air for these coils to come in from both sides and the bottom. All the coils in one "V" section serve one compressor. Each compressor has its own independent refrigerant circuit.

"The MicroTech III control is proactive in response to "off-design conditions". In the case of single or compounded influences restricting airflow to the unit, the microprocessor will act to keep the unit running (at reduced capacity), rather than allowing a shut-off on high discharge pressure.

Case 1: Building or Wall on One Side of One Unit

The existence of a screening wall or the wall of a building in close proximity to an air-cooled chiller is common in both rooftop and ground level applications. Hot air recirculation on the coils adjoining the wall will increase compressor discharge pressure, decreasing capacity and increasing power consumption.

When close to a wall, it is desirable to place chillers on the north or east side of them. It is also desirable to have prevailing winds blowing parallel to the unit's long axis. The worst case is to have wind blowing hot discharge air into the wall.

Installation and Application Information

Case 2: Two Units Side By Side

Two or more units sited side by side are common. If spaced closer than 12 feet (3.7 meters) it is necessary to adjust the performance of each unit; circuits adjoining each other are affected. If one of the two units also has a wall adjoining it, see Case 1. Add the two adjustment factors together and apply to the unit located between the wall and the other unit.

Mounting units end to end will not necessitate adjusting performance. Do not use pit or solid wall surrounds where the ambient air temperature exceeds 100F (38C).

Figure 9: Two Units Side by Side - Adjustment Factors

Case 3: Three or More Units Side By Side

When three or more units are side by side, the outside chillers (1 and 3 in this case) are influenced by the middle unit only on their inside circuits. Their adjustment factors will be the same as Case 2. All inside units (only number 2 in this case) are influenced on both sides and must be adjusted by the factors shown below.

Installation and Application Information

Case 4: Open Screening Walls

Decorative screening walls are often used to help conceal a unit either on grade or on a rooftop. Design these walls such that the combination of their open area and distance from the unit do not require performance adjustment. It is assumed that the wall height is equal to or less than the unit height when mounted on its base support. This is usually satisfactory for concealment. If the wall height is greater than the unit height, see Case 5, Pit Installation.

The distance from the sides of the unit to the side walls must be sufficient for service, such as opening control panel doors.

If each side wall is a different distance from the unit, the distances can be averaged providing either wall is not less than 8 feet (2.4 meters) from the unit. For example, do not average 4 feet and 20 feet to equal 12 feet (1 meter and 5 meters to equal 3 meters).Figure 11: Open Screening Walls - Adjustment Factors

Case 5: Pit/Solid Wall Installation

Pit installations can cause operating problems resulting from recirculation and restriction can both occur. A solid wall surrounding a unit is substantially the same as a pit and the data presented here should be used.

Steel grating is sometimes used to cover a pit to prevent accidental falls or trips into the pit. The grating material and installation design must be strong enough to prevent such accidents, yet provide abundant open area to avoid serious recirculation problems. Have any pit installation reviewed by the McQuay sales representative prior to installation to make sure it has sufficient air-flow characteristics, and approved by the installation design engineer avoid risk of accident.

Installation and Application Information

Chilled Water SystemsThe following sections offer supplemental information to that discussed in ASHRAE handbooks, which are a recommended source.

Water Flow

Chilled water systems are normally designed with leaving chilled water temperatures of 40°F to 50°F (4.4C to 10C), a 10F (5.6°C) water temperature difference and 0.0001

ft2•hr•°F/BTU (0.0176•m2•°C/kW) fouling factor. Catalog performance tables display data for the chillers at these conditions. Actual design can be different, and McQuay catalogs include adjustment factors or special rating tables to account for other conditions.

• Addition of secondary coolants such as ethylene glycol

• Variances from 10°F (5.6C) water temperature differ-ences

• Greater than standard water fouling

• Elevation and ambient air temperatures

Specifications and start-up procedures should confirm that the chilled water piping system had been properly flushed out before being connected to the chiller vessel.

Confirm that the piping contains:

• A cleanable 20-mesh strainer, installed at the evaporator inlet, to remove impurities before they reach the evapo-rator. The strainer shall be placed in the supply water line just prior to the inlet of the evaporator. Care should be exercised when welding pipe or flanges to the evaporator to prevent any slag from entering the evaporator.

• An expansion tank in the piping

• An air vent located at the system high point to purge trapped air in the piping system. An air vent is also located at the top of each water head of the evaporator. Each evaporator water head is also provided with a drain connection.

All water systems include air in solution with the water. The percentage of air that can be retained in solution is a function of the water temperature and water pressure. Since these two values change in both chilled and hot water systems, an expansion tank is vital to the successful operation of the system.

Many chiller installations today are replacements for older less efficient machines or chillers with obsolete refrigerants. Existing piping is drained down, opened to atmosphere, and reconnected to the new chiller vessel. Rust formed over the years can break loose during the replacement process, pass through a conventional strainer, and settle in the chiller vessel. Use a higher capacity filter and chemical treatment of the water for these installations.

Figure 13: Typical Chilled Water Piping

Note: The cross piping for the pressure gauge can be as small as ¼ inch. The purpose of this arrangement is to provide an easy method to use one gauge to accurately measure the evaporator pressure drop.

Optional Inlet Strainer

An inlet water strainer kit is available as a shipped-loose option, sized per Table • and with the pressure drop shown in Figure 14. The kit is field installed and consists of:

• Y-type 40% open area strainer with 304 stainless steel perforated basket, Victaulic pipe connections and strainer cap

• Extension pipe with two Schrader fittings that can be used for a pressure gauge and thermal dispersion flow switch. The pipe provides sufficient clearance from the evaporator for strainer basket removal.

• ½-inch blowdown valve

• Two Victaulic clamps

Installation and Application Information

Checking Water Flow

The simplest method of checking water flow in a clean system (the chiller vessel has not been fouled nor is air bound), is to read the entering and leaving pressures and compare the actual pressure drop to the value published in the product catalog.

Pressure drops at the job are read in psi or feet of water. Published values are displayed in feet of water. Use the following formula to convert from one to another.

Feet of water / 2.31= psi

System Water Volume

All chilled water systems need adequate time to recognize a load change, respond to that load change and stabilize, without undesirable short cycling of the compressors or loss of temperature control. In air conditioning systems, the potential for short cycling usually exists when the building load falls below the minimum chiller plant capacity or on close-coupled systems with very small water volumes.

Some things to consider when looking at water volume are the minimum cooling load, the minimum chiller plant capacity during the low load period and the desired cycle time for the compressors.

Assuming that there are no sudden load changes and that the chiller plant has reasonable turndown, a rule of thumb of “gallons of water volume equal to two to three times the chilled water gpm flow rate” is often used.

A properly designed storage tank should be added if the system components do not provide sufficient water volume.

Flow Switch

A flow switch must be included in the chilled water system to prove that there is adequate water flow to the evaporator before the unit can start or to shut down the unit if water flow is interrupted.

A solid state, thermal dispersion flow switch that is factory-mounted in the chiller leaving water nozzle and factory-wired is available as an option. A field-installed version is also available as an option.

Evaporator Freeze Protection

Evaporator freeze-up can be a concern in the application of air-cooled water chillers in areas experiencing below freezing temperatures. To protect against freeze-up, insulation and an electric immersion heater are furnished with the evaporator. This helps protect the evaporator down to -20°F (-29°C) ambient air temperature. Although the evaporator is equipped with freeze protection, it does not protect water piping external to the unit or the evaporator itself if there is a power failure or heater burnout, or if the chiller is unable to control the chilled water pumps. Use one of the following recommendations for additional protection:

• If the unit will not be operated during the winter, drain evaporator and chilled water piping and flush with glycol.

Drain and vent connections are provided on the evaporator for this purpose.

• Add a year-round glycol solution to the chilled water system to provide freeze protection. Freeze point should be approximately 10°F(5.6°C) below minimum design ambient temperature. The use of glycol anti-freeze is generally considered the safest protection against freeze-up, however, it will reduce the performance of the unit, depending the concentration. Take this into consideration during initial system design and selection. On glycol applications, a minimu

• The field addition of thermostatically controlled heat tracing and insulation to exposed piping. Factory insulation will have to be removed and replaced after installation of the tracing. (Dependent on power availability)

• Continuous circulation of water through the chilled water piping and evaporator. (Dependent on power availability).

• The evaporator immersion heateris factory wired to the 115-volt circuit in the control box. This power can be supplied from a separate source, or it can be supplied from the control circuit. Operation of the heater cable is automatic through the ambient sensing thermostat that energizes the evaporator heater cable for protection against freeze-up. Unless the evaporator is drained in the winter, the disconnect switch to the evaporator heater must be closed. Conversely, do not apply heat to the evaporator if it is drained.

Chilled Water Pump

It is important that the chilled water pumps be wired to, and controlled by, the chiller's microprocessor. When equipped with optional dual pump output, the chiller controller has the capability to selectively send the signal to a pump relay (by others) to start pump A or B or automatically alternate pump selection and also has standby operation capability. The controller will energize the pump whenever at least one circuit on the chiller is enabled to run, whether there is a call for cooling or not. This helps ensure proper unit start-up sequence. The pump will also be turned on when the water temperature reaches 1°F below the Freeze Setpoint to help prevent evaporator freeze-up. Connection points are shown in the Field Wiring Diagram on page 127.

Failure to allow pump control by the chiller may cause the following problems:

1 If any device other than the chiller attempts to start the chiller without first starting the pump, the chiller will lock out on the No Flow alarm and require manual reset.

2 If the evaporator water temperature drops below the “Freeze setpoint” the chiller will attempt to start the water pumps to avoid evaporator freeze. If the chiller

CAUTION

Adding glycol or draining the system is the recommended method of freeze protection. If the chiller does not have the ability to control the pumps and the water system is not drained in temperatures below freezing, catastrophic evaporator failure may occur.

Installation and Application Information

does not have the ability to start the pumps, the chiller will alarm due to lack of water flow.

3 If the chiller does not have the ability to control the pumps and the water system is not to be drained in temperatures below freezing, the chiller may be subject to catastrophic evaporator failure due to freezing. The freeze rating of the evaporator is based on the immersion heater and pump operation. The immersion heater itself may not be able to properly protect the evaporator from freezing without circulation of water.

Variable Speed Pumping

McQuay chillers are designed for variable water flow duty provided that the rate of change is less than 10 percent of the change (design flow minus minimum flow) per minute and, the minimum and maximum flow rates for the evaporator, listed on page 36, are not exceeded

Figure 15: Power Panel Components (Left &Right)

Electrical Connections

All wiring must be done in accordance with applicable local

and national codes. Pathfinder units can be ordered with either standard multi-point power or optional single point power connections and with various disconnect and circuit breaker options. Wiring within the unit is sized in accordance with the

U.S.A. National Electrical Code. Field-supplied disconnect switches are required if not factory-supplied with the unit.

Notes: Disconnect switches are molded case construction with lockable through-the-door handles. They can be used to remove the unit/circuit from the power system.The individual compressor isolation circuit breakers for each circuit isolate the compressor and do not have through-the-door handles. They are operable only after the panel doors are opened.The high short circuit rated panel means that a short circuit current up to the ratings shown in Table 4, Interrupt Ratings (kAmps)will be contained in the panel. There is a short period of time when the circuit breaker will short circuit before opening a circuit that can damage downstream components. In other words, the enclosure is stronger than a standard enclosure. It has a high interrupt rated disconnect switch.The factory-mounted control power transformer is protected by fuses.Condenser fans are protected and isolated by circuit breakers.

Disconnecting means are addressed by Article 440 of the U.S.A. National Electrical Code (NEC), which requires “disconnecting means capable of disconnecting air conditioning and refrigerating equipment including motor-compressors, and controllers from the circuit feeder.” Select and locate the disconnect switch per the NEC guidelines. Maximum recommended fuse sizes are given in the electrical data tables of this catalog for help in sizing the disconnect.

Terminals are provided in a unit control panel for optional field hookup of the control circuit to a separate fused 115-volt power supply in lieu of the standard factory installed control transformer.

Isolator Locations and Kit NumbersIsolator Locations and Kit Numbers

Transfer the unit as indicated in the Installation and Maintenance Manual, IM 997, available on www.mcquay.com. In all cases, set the unit in place and level with a spirit level. When spring-type isolators are required, install springs running under the main unit supports.

The unit should be set initially on shims or blocks at the listed spring free height. When all piping, wiring, flushing, charging, etc., is completed, the springs are adjusted upward to loosen the blocks or shims that are then removed.

A rubber anti-skid pad should be used under isolators if hold-down bolts are not used.

Installation of spring isolators requires flexible piping connections and at least three feet of flexible electrical conduit to avoid straining the piping and transmitting vibration and noise.

Mounting locations for each model can be found in the Lifting & Mounting Dimensions beginning on Page 98

Sound DataSound Data

Sound levels can be as important as unit cost and efficiency, and must be addressed before the start of any project design.

The Daikin McQuay Pathfinder chiller is engineered for quiet operation with aerodynamically designed fan blades, low speed motors and inherently quiet single screw compressors.

Standards

AHRI Has established standards to provide uniform methods for the determination of the sound levels of equipment. For large air-cooled chillers, it is AHRI Standard 370, Sound Ratings of Large Outdoor Refrigeration and Air-Conditioning Equipment. Data contained in this section are in accordance with this standard.

Background Information

Sound is a vibration in an elastic medium and is essentially a pressure and particle displacement phenomenon. A vibrating body produces compression waves and as the waves are emitted from the vibrating body, molecules are ultimately compressed. These values are transmitted through gases, liquids or solids-anything that is elastic or viscous.

The sound data provided in this section is presented with both sound pressure and sound power levels.

Sound Power Levels

Sound power is the total sound energy radiated by a source per unit of time integrated over the surface through which the sound is radiated. Sound power is a calculated quantity and cannot be measured directly like sound pressure. Sound power is not dependent on the surrounding environment or distance from the source. Sound measurements are taken over a prescribed area around the unit and the data is mathematically calculated to give the sound power in dB.

Sound Pressure Levels - Full Load

All sound pressure tables give the “A” weighted sound pressure levels (including individual octave bands), which are considered typical of what can be measured in a hemispherical field with a hand-held sound meter in the absence of any nearby reflective surfaces, other than the ground itself. The sound pressures is measured at 30 feet from the side of the unit, at 100% unit load, no reflecting walls (Q=2), and AHRI conditions; 95°F (35°C) ambient air temperature and 54/44°F (12.22/6.67°C) chilled water temperatures.

Sound pressure varies with the distance from the source and is dependent on its surroundings. For example, a brick wall located 10 feet from a unit (two reflecting surfaces, the roof and the wall) will affect the sound pressure measurements differently than a unit mounted on a roof with only one reflecting surface (the roof). Sound pressure is measured in decibels (dB), which is a dimensionless ratio (on a logarithmic scale) between measured sound pressure and a reference sound pressure level.

One-third Octave Band Sound Levels

The A-weighted sound rating method is good for evaluating the overall average sound levels, but does not adequately address the problem of “pure tones” in compressor sound levels. These dB spikes are much more objectionable to the listener than similar levels of broadband noise. AHRI standard 370 provides a method to evaluate these pure tones, and penalizes the sound ratings of compressors displaying these tonal spikes. The McQuay AWS chiller has been engineered for quiet operation, and the full one-third octave band spectrum is included in the following pages to allow for effective comparison with other units.

For more information on pure tones, see also:

• AHRI Standard 370 (2001)

• ASHRAE Fundamentals Handbook, chapter 7

• Addressing Noise Problems in Screw Chillers, ASHRAE Journal Article (June 1999)

Acoustic Analyzer Program

The McQuay Acoustic Analyzer program is a tool that has been developed to assist the designer in determining sound levels in specific installations using actual equipment sound ratings. It is available through your local McQuay sales office.

Sound Reduction Due to Distance from Unit

The distance between a source of sound and the location of the sound measurement plays an important role in minimizing sound problems. The equation below can be used to calculate the sound pressure level at any distance if the sound power is known. Results for typical distances are tabulated in Table 68. Another way of determining the effect of distance is to work from sound pressure only. “Q”, the directionality factor, is a dimensionless number that compensates for the type of sound reflection from the source. For example, a unit sitting on a flat roof or ground with no other reflective surfaces or attenuation due to grass, snow, etc., between source and receiver: Q=2.

Sound pressure can be calculated at any distance from the unit if the sound power is known.

Lp=Lw-(20 log r) + (10 log Q) -.5

Lp = sound pressure

r = distance from unit in feet

Lw = sound power

Q = directionality factor

Sound Data

With Q=1, Unit suspended in space (theoretical condition), the equation simplifies to:

Lp = Lw – (20)(log r) –0.5

With Q=2, for a unit sitting on a flat roof or ground with no adjacent vertical wall as a reflective surface, the equation simplifies to:

Lp = Lw – (20)(log r) + 2.5

With Q=4 for a unit sitting on a flat roof or ground with one adjacent vertical wall as a reflective surface, the equation simplifies to:

Lp = Lw – (20)(log r) + 5.5

The equations are reduced to table form in Table 68 for various distances and the two most usual cases of “Q” type of location.

Sound Isolation

The low sound level for the Pathfinder chiller satisfies most customer requirements. However, there can be applications where even lower sound levels are necessary. The most effective isolation method is to locate the unit away from sound sensitive areas. Avoid locations beneath windows or between structures where normal-operating sounds can be objectionable. Isolating water lines, electrical conduit and the unit itself can reduce structurally transmitted sound. Wall sleeves and rubber isolated piping hangers can be used to reduce transmission of water or pump noise into occupied spaces, and flexible electrical connections can be used to isolate sound through electrical conduit. Spring isolators are effective in reducing the low amplitude sound generated by screw compressors and can be used for unit isolation in sound sensitive areas.

Sound Pressure Levels, Low Ambient Operation

Unit operation at a lower ambient temperature than 95°F (35C) will also result in lower sound pressure levels. The sound pressure level will decrease approximately 1 dBA for ambient air temperatures between 85F and 94F (29.4C and 34.4C), approximately 2 dBA for ambient air temperatures between 75F and 84F (23.9C and 28.9C), and

approximately 3 dBA for ambient air temperatures between 65F and 74F (18.3C and 23.3).

Sound Pressure Levels, Multiple Units

Multiple air-cooled unit installations will have a higher sound level than a single unit. Two units will have approximately 3 dB higher sound level of one unit, four units will be approximately 6 dB louder, and eight units approximately 9 dB louder than one unit.

Sound Control

Walls adjacent to a unit 20 feet (6 meters) or less will reflect the unit sound outwards, increasing the sound pressure on the side away from the wall. This sound increase could be as high as 3 dB for one wall and as high as 6 dB for a corner location. Unit orientation and/ or distance as noted above will decrease sound levels.

Sound levels can also be controlled by the installation of barrier walls. To be effective as sound blockers, walls must be solid with no open penetrations. Sound tends to leak out of openings. Block walls with filler material and slots on the side facing the unit are especially effective. The wall should be about 10 feet (3 meters) high or 2 feet (0.6 meters) higher than the unit and located at least 10 feet (3 meters) away so as not to affect unit performance. A three-sided enclosure will be the most effective solution and will reduce sound levels by about 10 dB. Remember that the wall will increase the sound level on the side opposite it by 3 to 6 dB (one or three-sided wall).

Note: The effect of adjacent walls on air recirculation and restriction must always be considered when using sound barrier walls.

Electrical DataElectrical Data

Field WiringWiring must comply with all applicable codes and ordinances. Warranty does not cover damage to the equipment caused by wiring not complying with specifications. Pathfinder chillers can be ordered with main power wiring for either multi-point power connection (standard) or single-point connection (optional). If the optional single-point power connection is ordered, a single power connection is made to a power block (or optional disconnect switch) in the unit power panel. A separate disconnect is required if the optional factory-mounted disconnect is not ordered. Factory-mounted isolation circuit breakers for each circuit are included as standard on all single-point connection options.

If the standard multiple-point power wiring is ordered, two power connections are required on Pathfinder chiller models AWS###BDS or three power connections on AWS###BTS. They are made to factory-mounted disconnect switches in the power panel. See the dimension drawings beginning on page 67 for entry locations.

An open indicates a short, ground, or overload. Before replacing a fuse or restarting a compressor or fan motor, the trouble must be found and corrected.Copper wire is required for all power lead terminations at the unit, and copper must be used for all other wiring to the unit.

It can be desirable to have the unit evaporator heaters on a separate disconnect switch from the main unit power supply so that the unit power can be shut down without defeating the freeze protection provided by the evaporator heaters. See the field wiring diagram on page 127 for connection details. The 120-volt control transformer is factory mounted and wired. .

Electrical Data Notes

1 Explanation of field wiring designation:

Note: NOTE: Wire size shown is for illustrative purposes only.2 Allowable voltage limits:• Unit nameplate 460V/60Hz/3Ph: 414V to 506V • Unit nameplate 575V/60Hz/3Ph: 517V to 633V

3 Unit wire size ampacity (MCA) is equal to 125% of the largest compressor-motor RLA plus 100% of RLA of all other loads in the circuit including control transformer. Wire size ampacity for separate 115V control circuit power is 15 amps.

4 Units marked with (*) - These units require the use of a 100% rated disconnect; therefore, wire will be sized per 75ºC NEC ratings, however 90ºC wire must be used.

5 Compressor RLA values are for wire sizing purposes only, but do reflect normal operating current draw at unit rated capacity.

6 Single-point power supply requires a single disconnect to supply electrical power to the unit. Power must be fused.

7 Multiple point power supply requires a independent power supply for each circuit.

8 All field wiring to unit power block or optional nonfused disconnect switch must be copper.

9 Field wire size values given in tables apply to 75°C rated wire per NEC.

10 External disconnect switch(s) or HACR breakers must be field supplied. On single-point power units, a non-fused disconnect switch in the panel is an available option.

11 All wiring must be done in accordance with applicable local and national codes.

12 Recommended time delay fuse size is equal to 170% of the largest compressor motor RLA plus 100% of remaining compressor RLAs and the sum of condenser fan FLAs.

13 Maximum time delay fuse size or HACR breakers is equal to 225% of the largest compressor-motor RLA plus 100% of remaining compressor RLAs and the sum of condenser fan FLAs.

14 Power Limitations:• Voltage within 10 percent of nameplate rating.• Voltage unbalance not to exceed 2% with a resultant cur-

rent unbalance of 6 to 10 times the voltage unbalance per NEMA MG-1, 1998 Standard.

15 Circuit Breakers (Non-Compressor VFD Units)• The circuit breaker used in the High Short Circuit panel

option may have a higher trip rating than the unit Maxi-mum Overload Protection (MOP) value shown on the unit nameplate. The circuit breaker is installed as a ser-vice disconnect switch and does not function as branch circuit protection, mainly that the protection device must be installed at the point of origin of the power wiring. The breaker (disconnect switch) is oversized to avoid nuisance trips at high ambient temperature conditions.

16 BAS Interface• The following installation manuals for optional BAS

interface modules are shipped with the chiller. They can also be found and downloaded on www.mcquay.com under Product Information > Air cooled Chillers> Screw Type > Control Integration:

• IM 966, BACnet® IP Communication Module• IM 967, BACnet® IP Communication Module MS/TP• IM 968, Modbus® Communication Module• IM 969, LONWORKS Communication Module

CAUTION

If a separate disconnect is used for the 120V supply to the unit, it must power the entire control circuit. It must be clearly marked so that it is not accidentally shut off during freezing temperatures, thereby de-energizing the evaporator heaters. Freeze damage to the evaporator could result. If the evaporator is drained for winter freeze protection, the heaters must be de-energized to prevent heater burnout.

CAUTION

Pathfinder unit compressors are single-direction rotation compressors and can be damaged if rotated in the wrong direction. For this reason, proper phasing of electrical power is important. Electrical phasing must be A, B, C for electrical phases 1, 2 and 3 (A=L1, B=L2, C=L3) for single or multiple point wiring arrangements. The solid-state starters contain phase reversal protection. DO NOT ALTER THE WIRING TO THE STARTERS.

Options and AccessoriesOptions and Accessories

Unit

Right-hand Evaporator Water Connections

Right-hand evaporator water connections (as viewed from the control panel) are an available option.

Black Fin Coil

Aluminum fin stock is pre-coated with a phenolic-epoxy coating with 1000-hour salt spray resistance (ASTM B117-90).

Copper Fin Condenser Coils

Copper fin condenser coils are available as an option on all models for corrosion protection.

Baked Epoxy Condenser Fin Coating

ElectroFin™ flexible dip and baked epoxy protective coating with 5000+ hour salt spray resistance (ASTM B117-90) is available on the condenser coils and coil frames. Provides protection against adverse environments such as salt air as found on seacoast applications and many chemical environments. The coating can be applied to copper or aluminum coils. Consult the local McQuay sales office for complete specification and chemical resistance chart.

Protective Base Guards

Optional factory installed wire mesh lower base guards provide protection for ground level installations. Wire mesh coil guards are standard.

Louvers (Wind and Hail Protection)

Coil-Only Louvers

The presence of wind will have an adverse affect on any air-cooled chiller. Wind across a condenser coil will not allow a chiller to operate as efficiently, or possibly not even start, at low ambient temperatures. Wind raises the minimum ambient temperature in which the chiller can operate. The Pathfinder air-cooled chillers are available with factory-installed (or as a field-installed kit) coil louvers, which allow the chiller to operate effectively down to the ambient temperature for which it was designed.

Hail can have a damaging effect on the performance of an air-cooled condenser. As the outer finned area is flattened against the coil, restricting airflow, the efficiency of the coil is reduced.

Coil and Base Louvers

The coil louvers can also be supplied with base louvers, which when combined, enclose the entire side and end of the unit. The base louvers are primarily for appearance and provide some protection against vandalism. This option is available as factory-mounted or as a field-installed kit.

Vibration Isolators

Spring or rubber-in-shear vibration isolators are available for field installation under the unit base frame on sound sensitive applications. Consult the local McQuay sales office for seismic isolation.

Double Evaporator Insulation

Double evaporator thermal insulation is available and recommended for low fluid temperature applications.

Sound Enclosures

Removable compressor sound reduction enclosures reduce unit overall sound level. Not available on models with VFD.

Suction Shutoff Valves

Factory-mounted suction shutoff valves that, when used in conjunction with the compressor discharge valve, isolate the compressor for service.

Liquid line Solenoid Valve

Factory-mounted liquid line solenoid valve acts in conjunction with the electronic expansion valve for liquid shutoff to the evaporator.

Evaporator Inlet Strainer

Evaporator inlet water strainer kit consisting of Y-type strainer with 304 stainless steel perforated basket, blowdown valve, matching pipe extension with two Schrader fittings and two Victaulic couplings; all for field installation. See page 13 for details.

Controls

Water Flow Switch (Field-Installed, Paddle Type)

(Part Number 01750330) A 150 psig water flow switch is available for field installation in the chilled water piping to protect against evaporator freeze-up under low, or no flow conditions. Terminals are provided in the unit control center for field connection of the water flow detection switch. A flow detection device of some type is required.

Water Flow Switch (Factory-Installed, Solid State)

A solid-state thermal dispersion flow switch located in the evaporator outlet nozzle is factory installed and wired. In addition to the electronic output signal, the switch has an LED display to visually indicate the presence of flow.

The 24 Vac powered flow sensor is a solid-state alternative to mechanical switches for sensing the acceptable flow rate of water. These compact units are constructed of corrosion-resistant materials and 316 stainless steel parts and installed directly through a ¼ inch NPT into the flow.

The flow sensors operate on the calorimetric principle. The sensors use the cooling effect of a flowing fluid to provide

CAT 600-6 171

Options and Accessories

reliable flow rate detection of liquids over a very wide flow range. The amount of thermal energy that is removed from the tip determines the local flow rate and when it exceeds a setpoint it changes the output-state.

BAS Modules

A factory-installed communication module allows as BACnet w/ MSTP, BACnet w/ Ethernet, LonMark or Modbus. communications with BAS standard protocols. See for details. The module can also be retrofitted after shipment.

Remote User Interface

A remote control panel that mimics operation of the controller located on the unit. Up to eight Pathfinder units can be connected to it and selected on the screen. It provides HMI (Human Machine Interface) within a building, the building engineer's office for example, without going outdoors to the unit. It can be ordered and shipped loose as a field installed option. The remote panel is powered from the unit and no additional power supply is required.

High Ambient Operation

This option is required for operation at ambient temperatures above 100°F (38°C), up to 125°F (51°C) or when the unit is equipped with the VFD low ambient fan control option. The kit includes a thermostat controlled, panel ventilation fan and inlet grille with filter. The option can be ordered with any unit. Compressor loading and unloading is adaptively determined by system load, ambient air temperature and other inputs to the MicroTech III control algorithms.

Low Ambient Operation

Factory mounting of a variable frequency drive (VFD) motor on the lead condenser fan motor for each circuit provides for chiller operation between 35°F (2°C) and 0°F (-18 C). Line reactors for the VFDs are included. This option requires the addition of the High Ambient Operation option to remove excess VFD heat.

Electrical

Power Factor Correction Capacitors

Factory-installed PFCC option improves the compressor power factor to at least .95 at full load. Available on most non-vfd models (models with VFD achieve .94-.95 correction without capacitors). See Physical Data beginning on page 43 for weight-add for PFCC option.

RapidRestore™ and Fast Loading

Data center and other critical installations often require a fast return to 100% cooling load after a power interruption. McQuay's RapidRestore provides a 30-second restart capability. The power interruption must be longer than one second and the Start-to-Start timer timed out.

Power Connections

The standard power connection is multi-point to disconnect switches (two or three) with through-the-door handles and no individual branch circuit breakers.

Note: See page 126 for ratings of standard and optional electrical panels.

Single-Point Connection to Disconnect Switch

Single-Point Connection with High Short-Circuit Current Rated Panel

High short-circuit current rated panel. Includes high interrupting capacity unit disconnect switch and factory-wiring to standard isolating circuit breakers for each circuit. Interrupt ratings are shown in Table 4, page 15. The high short circuit rated panel means that a short circuit current up to the ratings shown in Table 4 will not destroy the enclosure, even though the internal components may be destroyed.

Multi-Point Connection with High Short Circuit Current Rated Panel

High short-circuit current rated panel. Includes two or three high interrupting capacity disconnect switches. Interrupt ratings are shown Table 4, page 15. Isolating circuit breakers for each compressor are not included. The high short circuit rated panel means that a short circuit current up to the ratings shown in Table 4 will not destroy the enclosure, even though the internal components may be destroyed.

Single-Point Connection to Power Block

Single -point connection to a power block with isolating circuit breakers for each circuit.

Wye-Delta Compressor Starters

Wye-delta starters in lieu of the standard solid-state starters.

Phase/Voltage Monitor
