The Trailblazer® family of air-cooled scroll chillers continues the Daikin Applied legacy of high quality, high efficiency, latest technology and quiet operation. These features make the Trailblazer® family the best overall value in air-cooled packaged chillers available today. The Trailblazer® series offers a wide selection of units from 30 to 241 tons with dual refrigerant circuits available as packaged units with optional heat recovery or pump packages, or as remote evaporators.

Efficient OperationThe Trailblazer® units utilize environmentally acceptable R-410A refrigerant and meet the performance requirements of ASHRAE Standard 90.1 for efficiency. Excellent part-load performance is achieved with four or six scroll compressors. A variable speed condenser fan option is also available to provide even higher part load efficiency. High overall efficiency = lower annual energy costs.

RapidRestore® and Fast LoadingWhen power has been interrupted, the Trailblazer® has the capability to restore cooling quickly by using RapidRestore® and Fast Loading. These options make Trailblazer® ideal for mission critical buildings, data centers, healthcare facilities, and manufacturing processes. Once power is restored after a power loss duration of up to 180 seconds, the time for a Trailblazer® chiller to restart is less than 125 seconds with the chiller reaching full load within 220 seconds.

Application FlexibilityTrailblazer® units are available as packaged chillers with optional heat recovery or pump packages, as well as remote evaporator configurations. Information on remote evaporator models and factory-installed pump packages can be found in a separate installation manual available on www.DaikinApplied.com.

Quiet OperationThe Trailblazer® units live up to the Daikin Applied reputation for low operating sound levels and make these chillers “neighborhood friendly.” Full load sound pressure levels as low as 60 dB without insulation.

LEED® Points For building owners who wish to pursue Leadership in Energy and Environmental Design (LEED®) Green Building Certification, points earned for Optimize Energy Performance (formerly EA Credit 1) are awarded based on overall building efficiency. The high efficiency of the AGZ-E will contribute to the total points earned for this credit. Trailblazer® chillers can also contribute to Enhanced Refrigerant Management (formerly EA Credit 4) qualification which is partially determined by tonnage and refrigerant quantity. Consult with your Daikin Applied sales representative for more information.

CHILLER NOMENCLATURE

A G Z XXX E D

Unit Design Features Daikin Trailblazer® air-cooled chillers are a product of our commitment to offer quiet, reliable, energy efficient equipment, incorporating high quality compressors, and innovative packaging.

ConstructionTrailblazer® chillers are factory-assembled and mounted on a heavy-gauge steel base. The base distributes the unit weight for roof loading. Their small footprint allows smaller mounting pads or support structures and is a plus for retrofit or replacement applications.

CompressorsReliable hermetic scroll compressors with cast iron scrolls and three Teflon® impregnated bearings are used on the Trailblazer® chillers to promote longevity.

Each model has the ability to modulate its capacity. Models with four compressors will have four steps of capacity modulation while models with six compressors will have six steps. Compressors stage on depending on the load of the system. This results in excellent part-load efficiency and reduced annual operating costs.

Features include motor temperature protection, scroll temperature protection, missing phase protection, reverse phase protection, low control circuit voltage protection, short cycling detection and alert, Modbus® communication to system controller, operational and fault history storage, and LED status display.

EvaporatorTrailblazer® units are designed to maximize efficiency in the smallest possible footprint. The evaporator is a compact, high efficiency, dual circuit, brazed plate-to-plate type heat exchanger consisting of parallel stainless steel plates. These heat exchangers provide excellent heat exchange efficiency in a compact footprint and are especially attractive for smaller capacity units. Evaporators are designed and constructed according to, and listed by, Underwriters Laboratories (UL).

Optional Remote Evaporator Units 30-241 tons with the optional remote evaporator will have the evaporator shipped separately for field mounting and piping to the outdoor unit.

Condenser CoilsCondenser coils are all aluminum alloy microchannel design with a series of flat tubes containing multiple, parallel flow microchannels layered between the refrigerant manifold piping. See “Condenser Coil Options and Coating Considerations” on page 15 for discussion of environmental factors related to material and coating options.

Optional High Efficiency Variable Speed Condenser FansThis option (available on 75-241 ton models) adds variable speed drives to the condenser fans on the chiller. The MicroTech® III controller will adjust the speed of the condenser fans using the VFD’s to optimize chiller efficiency and maintain proper head pressure. This feature improves part load efficiency substantially and offers the ability to operate in low ambient conditions down to -10°F.

All High Efficiency Trailblazer® models with fully variable speed fans also include a sound reduction mode to allow for reduced-sound operation. Based on a user-settable time schedule, the chiller will enter the reduced noise mode, which will limit the speed of the condenser fans in order to reduce sound levels. This feature is especially helpful in areas that have more rigorous sound restrictions during certain times of day. While the lower fan speed may have a slight impact on the maximum unit capacity during hot outdoor conditions, the chiller can be set to automatically override the fan speed restrictions if additional capacity is needed. This way, the unit will always optimize between required capacity and the lowest sound level possible.

Control SystemThe MicroTech® III advanced chiller controller surpasses all other microprocessor-based chiller control systems available today. This powerful, user-friendly control system provides the flexibility and performance needed for either stand-alone unit operation or the controller can be easily tied into the building automation system of choice using the Daikin Open ChoicesTM feature.

Open ChoicesTM allows one to choose from open standard protocols such as BACnet®, Modbus® and LonWorks® to communicate easily with the building automation system that best meets the facility requirements. These optional communications modules are available factory installed or can be easily field installed.

The MicroTech® III controller’s design will not only permit the chiller to run more efficiently, but will also simplify troubleshooting if a system failure occurs. Every MicroTech® III controller is programmed and tested prior to shipment to help provide a trouble-free start-up.

Figure 3: Optional Pump Package Schematic

Standard ComponentsSingle Pump: Single spring inside seal, vertical, in-line, radially split-case pump, serviceable without breaking pipe connections. The motor and pump rotating assembly can be serviced without removing the pump casing from the line.

Dual Pumps in a Single Casting: Single spring inside-seal vertical, in-line, radially split-case pumps, mounted in a common casing with a common inlet connection and outlet connection and including a flapper valve to prevent recirculation when only one pump is operating. An isolation valve is included that allows one pump to operate when the other is removed. The pumps are designed for duty/standby, not parallel operation. All information and performance curves for the single pump arrangement (Model 4380) can be used for the dual pump arrangement (Model 4392).

The package is also is equipped with:

• “Y” type inlet strainer • combination triple-duty outlet valve containing:

— discharge shutoff valve — check valve — flow throttling valve

• combination suction guide with flow stabilizing outlet vanes and stainless steel strainer with a disposable fine-mesh start-up strainer

• mounted and wired flow switch • factory power and control wiring • interconnecting piping and insulation of all cold surfaces

Various tank and connection options are available for field mounting. Refer to the schematic in Figure 3 for more information.

Optional Variable Flow VFDThe operating cost savings resulting from using variable chilled water flow via a pump VFD is well known. In the past, however, its usage has been somewhat limited by the cost and uncertainty of field installing the required system pressure differential sensors.

Daikin Applied can now offer flow control through the pump VFD without the need for external pressure sensors. In addition to the sensorless operation, there are three other selectable operating modes:

BAS Input: The pump speed and system flow will be controlled from a customer-supplied BAS input signal.

Remote Sensor Control: The VFD is wired to a pressure sensor mounted in the chilled water piping system. This is the standard VFD control when a sensorless VFD is not used.

Locally Selected Constant Speed Control: Provides manual control of the pump speed, overriding any current automatic speed control.

Consult the current version of the installation manual for additional detailed information, which is available from your local Daikin Applied sales office or on www.DaikinApplied.com.

Optional Partial Heat Recovery Partial heat recovery (available on 75-241 ton models) adds optional factory-installed heat exchangers and control logic to provide hot water for many uses such as dehumidification and pre-heating water for a boiler. This option reduces operating costs by using heat that already exists in the chiller instead of paying for another source of energy.

Unit PlacementTrailblazer® units are for outdoor applications and can be mounted either on a roof or at ground level. For roof mounted applications, install the unit on a steel channel or I-beam frame to support the unit above the roof. For ground level applications, install the unit on a substantial base that will not settle. Use a one-piece concrete slab with footings extended below the frost line. Be sure the foundation is level within 0.5” (13 mm) over its length and width. The foundation must be strong enough to support the unit weight - see the Dimensions section starting on page 29.

Service ClearanceSides

• Models 30-70: Minimum of 4 feet (1.2 meters)• Models 75-241: It is highly recommended to provide

a minimum of 8 feet (2.4 meters) on one side to allow for coil replacement. Coils can be removed from the top, allowing a minimum of 4 feet (1.2 meters) of side clearance; however, the unit performance may be derated.

Control Panel End

• All Models: Minimum of 4 feet (1.2 meters)Opposite Control Panel End

• Models 30-70: Minimum of 7.5 feet (2.3 meters)

• Models 75-241: Minimum of 4 feet (1.2 meters)

Figure 5: Service Clearance

Operational Spacing RequirementsSufficient clearance must be maintained between the unit and adjacent walls or other units to allow the required unit air flow to reach the coils. Failure to do so will result in a capacity reduction and an increase in power consumption. No obstructions are allowed above the unit at any height. The clearance requirements shown are a general guideline and cannot account for all scenarios. Such factors as prevailing winds, additional equipment within the space, design outdoor air temperature, and numerous other factors may require more clearance than what is shown. Additional clearances may be required under certain circumstances.

Graphs on the following pages give the minimum clearance for different types of installations and also capacity reduction and power increase if closer spacing is used. The graphs are based on individual cases and should not be combined with other scenarios.

Case 1: Building or Wall on One Side of Unit NOTE: Assumes a solid height wall taller than unit. Refer to

Case 4 for partial wall openings.

For models AGZ030-101E, maintain a 4 foot minimum from any solid height wall taller than unit.

For models AGZ110-130E, maintain a 6 foot minimum from any solid height wall taller than unit.

For models AGZ140-241E, maintain an 8 foot minimum clearance from any solid height wall taller than unit.

Figure 6: Building or Wall on One Side of Unit

Case 2: Two Units, Side-by-SideFor models 030-180, there must be a minimum of 4 feet between two units placed side-by-side; however, performance may be affected at this distance. For models 191-241, the minimum is 6 feet as closer spacing may cause air recirculation and elevated condenser pressure. Assuming the requirement of one side having at least 8 feet of service clearance is met, Figure 8 below shows performance adjustments as the distance between two units increases.

Case 3: Three or More Units, Side-by-SideFor all models, there must be a minimum distance between any units placed side-by-side; however, performance may be affected at this distance. Minimum distances are: models 030 to 070 - 4 feet, models 075 to 101 - 5 feet, models 110 to 241 - 6 feet. Figure 11 and Figure 12 depict Case 3 performance adjustments as the distance between units increases.NOTE: Data in Figure 11 and Figure 12 is for the middle unit

with a unit on each side. See Case 2 adjustment factors for the two outside units.

Figure 10: Three or More Units, Side-by-Side

Figure 11: Case 3 - Full Load Capacity Reduction

Figure 12: Case 3 - Power Increase

Case 4: Open Screening Walls Screening walls may be used to help conceal a unit. When possible, design these walls such that the combination of open area and distance from the unit (see Figure 13) does not require performance adjustment. If the wall opening percentage is less than recommended for the distance to the unit, it should be considered as a solid wall. It is assumed that the wall height is equal to or less than the unit height when mounted on its base support. If the wall height is greater than the unit height, see Case 5 for adjustment factors. The distance from the sides of the unit to the walls must be sufficient for service. For uneven wall spacing, the distance from the unit to each wall can be averaged providing no distance is less than 4 feet. Values are based on walls on all four sides.

Case 5: Pit Installation Pit installations can cause operating problems resulting from air recirculation and restriction and require care that sufficient air clearance is provided, safety requirements are met and service access is provided. A solid wall surrounding a unit is substantially a pit and this data 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 recirculation problems. Have any pit installation reviewed by your Daikin Applied sales representative prior to installation to ensure it has sufficient air-flow characteristics, and confirm it has been approved by the installation design engineer to avoid risk of accident. The following de-rates are based on single chiller installations only.

Chilled Water Piping All evaporators and condensers have OGS-type grooved waterconnections (adhering to Standard AWWA C606) or optionalflange connections. The installing contractor must providematching mechanical connections. PVC piping should not beused. Be sure that water inlet and outlet connections matchcertified drawings and nozzle markings.

Field-installed water piping to the chiller must include:

• A cleanable strainer installed at the water inlet to the evaporator to remove debris and impurities before they reach the evaporator, causing damage. See the Inlet Strainer Guidelines and the current version of the product Installation, Operation and Maintenance manual on www.DaikinApplied.com for additional details.

• Adequate piping support to eliminate weight and strain on the fittings and connections.

• A water flow switch must be installed in the horizontal piping of the supply (evaporator outlet) water line to avoid evaporator freeze-up under low or no flow conditions. The flow switch is supplied by the factory as an installed component or a field-installed kit shipped along with the unit. (See page 55 for more information.)

• Piping for units with brazed-plate evaporators must have a drain and vent connection provided in the bottom of the lower connection pipe and to the top of the upper connection pipe respectively, see Figure 23. These evaporators do not have drain or vent connections due to their construction.

It is recommended that the field-installed water piping to the chiller include:

• Thermometers at the inlet and outlet connections of the evaporator.

• Water pressure gauge connection taps and gauges at the inlet and outlet connections of the evaporator for measuring water pressure drop.

• Vibration eliminators in both the supply and return water lines. Pressure gauges must be installed in the inlet and outlet water lines to the evaporator.

• Insulated chilled water piping to reduce heat loss and prevent condensation. For information on freeze protection, see “Evaporator Freeze Protection” on page 13.

1. A factory installed option.

2. A field-installed kit shipped-loose with the unit that consists of:

• Y-type 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.

• 0.5-inch blowdown valve • Two grooved clamps

Both are sized per Table 2 and with the pressure drop shown in the Strainer Pressure Drop graph. Connection sizes are given in the physical data section beginning on page 25.

3. A field-supplied strainer that meets specification and installation requirements of the current Installation, Operation and Maintenance Manual available at www.DaikinApplied.com.

Water Flow Limitations Constant FlowThe evaporator flow rates and pressure drops shown in Figure 30 on page 22 and Table 14 on page 23 are for full load design purposes. The maximum flow rate and pressure drop is based on a 6°F temperature drop. Flow rates above the maximum values will result in unacceptable temperature and pressure drops and can cause excessive erosion, potentially leading to failure.

The minimum flow and pressure drop is based on a full load evaporator temperature drop of 16°F. Evaporator flow rates below the minimum values can result in laminar flow causing freeze-up problems, scaling and poor control.

Variable FlowReducing evaporator flow in proportion to load can reduce system power consumption. The rate of flow change should be

a maximum of 10 percent of the flow per minute. For example, if the maximum design flow is 200 gpm and it will be reduced to a flow of 140 gpm, the change in flow is 60 gpm. Ten percent of 200 gpm equals 20 gpm change per minute, or a minimum of three minutes to go from maximum to desired flow. The water flow through the evaporator must remain between the minimum and maximum values listed in Table 14 on page 23. If flow drops below the minimum allowable, large reductions in heat transfer can occur. If the flow exceeds the maximum rate, excessive pressure drop and tube erosion can occur.

System Water Volume ConsiderationsAll chilled water systems need adequate time to recognize a load change, respond to the change and stabilize to avoid 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 of the things the designer should 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 storage tank may have to be added to the system to reach the recommended system volume.

Evaporator Freeze ProtectionEvaporator 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 heater are furnished with the evaporator. AGZ-E chillers have an external plate heater and thermostat that 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 does not directly control the chilled water pumps. Use one of the following recommendations for additional protection:

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

2. 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 or 10°F below the lowest design leaving water temperature, whichever is lower. 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 minimum fluid concentration should be based on Burst Protection limits.

3. The field installation of thermostatically controlled heat tracing and insulation to exposed piping. Factory insulation will have to be removed and replaced after installation of the tracing.

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

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

Chilled Water PumpIt is important that the chilled water pumps be wired to, and controlled by, the chiller’s microprocessor. 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 remains equal to or goes below the Freeze Setpoint for longer than a specified time to help prevent evaporator freeze-up. Connection points are shown in the Field Wiring Diagram on page 45 and page 46.

CAUTIONAdding 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.

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

High Ambient OperationTrailblazer® units for high ambient operation (105°F to 125°F, 40°C to 52°C) require the addition of the optional high ambient package that includes a small fan with a filter in the air intake to cool the control panel. All units with the optional VFD low ambient fan control include the high ambient option.

Low Ambient OperationCompressor staging is adaptively determined by system load, ambient air temperature, and other inputs to the MicroTech® III control. The standard minimum ambient temperature is 32°F (0°C). A low ambient option with fan VFD allows operation down to -10°F (-23°C). The minimum ambient temperature is based on still conditions where the wind is not greater than 5 mph. Greater wind velocities will result in reduced discharge pressure, increasing the minimum operating ambient temperature. Field-installed louvers are available and recommended to help allow the chiller to operate effectively down to the ambient temperature for which it was designed.

Partial Heat RecoveryPartial heat recovery for Trailblazer® chillers is achieved by adding an auxiliary heat exchanger in each unit refrigerant circuit between the compressors and the condenser coils. The heat exchangers transfer the heat from the compressor discharge gas to a separate water loop which can be used for various heating applications. The heating recovery cycle is only available when the chiller is running. The partial heat recovery auxiliary heat exchanger can return water up to 155°F; however, this value cannot be set. The amount of heat produced can be up to 50% of the nominal cooling capacity and is dependent on the requested cooling load, the operating temperatures, and the water flow rate through the auxiliary heat exchangers. Please note, if potable water is desired, a secondary heat exchanger in a separate water loop must be used. Contact your local Daikin Applied for information on specific applications.

Partial heat recovery components that are factory-supplied:

• Brazed plate heat exchangers - one in each circuit with the water piped together in parallel for one inlet and one outlet water connection, see Figure 31 for pressure drops.

• Insulation of heat exchangers and water piping at the unit.• Separate temperature sensors for inlet and outlet water

piping at the heat exchangers.• Connections for air vent at the outlet water piping and

drain at the inlet water piping.• Immersion heater for each auxiliary heat exchanger for

freeze protection.Required partial heat recovery field piping (see Figure 26) and connections (see page 47) are listed below.

• An external 3-way valve or a variable speed pump in the auxiliary heat exchanger water piping for modulation of flow through the heat exchangers by the unit controller. Heat recovery water loop pump must also be controlled by the chiller controller.

• A cleanable strainer with perforations no larger than 0.063” (1.6 mm) diameter must be installed within 5 feet (1500 mm) of pipe length from the heat exchanger inlet and downstream of any welded connections, see Figure 24 for pressure drop.

• Water piping and other portions of the heat recovery water loop must be insulated to prevent heat loss and possible injury due to hot surfaces.

• A field-installed safety or relief valve on the water side is required to prevent risks in case the water temperature thermostat should fail.

• Separate 120 volt power supply for immersion heaters. A junction box for a 120 Volt power connection is provided.

• A water tank and an additional water heater is suggested in the heat recovery piping loop for initial water temperature control and better loop stability. Typical loop sizing guidance is water volume (in gallons) be greater than or equal to two to three times the heat recovery water flow rate (in gallons/minute).

Condenser Coil Options and Coating ConsiderationsThe standard coils on the Trailblazer® chiller are an all aluminum alloy microchannel design with a series of flat tubes containing multiple, parallel flow microchannels layered between the refrigerant manifolds. The microchannel coils are designed to withstand 1000+ hour acidified synthetic sea water fog (SWAAT) test (ASTM G85-02) at 120°F (49°C) with 0% fin loss and develop no leaks. The all-aluminum microchannel coils provide superior longevity and durability for non-corrosive applications.

NOTE: 1. Non-corrosive environments may be estimated by the

appearance of existing equipment in the immediate area where the chiller is to be placed.

2. Marine environments should take into consideration proximity to the shore as well as prevailing wind direction.

3. Industrial contaminants may be general or localized, based on the immediate source of contamination (i.e. diesel fumes due to proximity to a loading dock).

4. Combined marine-industrial are influenced by proximity to shore, prevailing winds, general and local sources of contamination.

.

Epoxy coil coating is a water-based extremely flexible and durable epoxy polymer coating uniformly applied to all coil surfaces through a multi-step, submerged electrostatic coating process. Epoxy-coated condenser coils provide a 6000+ hour salt spray resistance per ASTM B117-90, applied to both the coil and the coil frames. The epoxy-coated coils also receive a UV-resistant urethane top-coat to provide superior resistance to degradation from direct sunlight. This coil coating option provides the best overall protection against corrosive marine, industrial or combined atmospheric contamination. This coating option may be applied to any of the untreated coil options offered, to provide excellent longevity and resistance to corrosion.

Background InformationSound levels can be as important as unit cost and efficiency. The inherently quiet scroll compressors used in Trailblazer® chillers are coupled with precision engineering for industry-leading sound levels.

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.

“A” WeightingSound values may be represented several ways. One of the more common forms is the “A” weighted value, which adds or subtracts a specific amount to each center band frequency, then logarithmically adds the values to establish a single value. The “A” scale is used to represent how the human ear receives sound. The amount added in each frequency band directly corresponds to how sensitive the human ear is to each frequency.

Table 4: “A” Scale Relative Response to Human Ear

dB(A) −39.4 −26.2 −16.1 −8.6 −3.2 0 +1.2 +1.0 −1.1 −6.6

Sound Pressure Levels - Full LoadSound pressure is the sound level that can be measured at some distance from the source. Sound pressure varies with distance from the source and depends on the surroundings. For example, a brick wall (a reflective surface) located 10 feet from a unit will affect the sound pressure measurements differently than a brick wall at 20 feet. Sound pressure is measured in decibels (dB).

All sound pressure data in the following pages are considered typical of what can be measured in a free field with a handheld sound meter, in the absence of any nearby reflective surfaces except the floor under the unit. Sound pressure levels are measured at 30 feet (10 meters) from the side of the unit at 100% load and standard AHRI conditions (per AHRI standard 550/590) of 95°F (35°C) ambient air temperature and 44°F (7°C) leaving evaporator water temperatures for air-cooled units.

Sound Power LevelsSound 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, as is sound pressure. It can be thought of as basic sound level emanating from the unit without consideration of distance or obstructions. Measurements are taken over a prescribed area around the unit and the data is mathematically calculated to give the sound power, dB. Acoustical consultants sometimes use sound power octave band data to perform a detailed acoustical analysis.

Figure 28: Sound Power vs. Sound Pressure

The data in Table 6 on page 18 and Table 10 on page 20 present sound power levels per AHRI Standard 370, “Sound Rating of Large Outdoor Refrigerating and Air Conditioning Equipment”. This standard was developed to establish uniform methods of determining the sound power radiated by large outdoor equipment. Measurements are taken over a prescribed area around the unit and the data is mathematically calculated to give the sound power, dB.

Sound Reduction due to Distance from the UnitThe distance between a source of sound and the location of the sound measurement plays an important role in minimizing sound problems. Sound pressure can be calculated at any distance from the unit if sound power and “Q,” the directionality factor, are known. “Q” 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 will have Q=2. See Figure 29 for definitions of Q=1, Q=2, and Q=4.

Figure 29: “Q” Reflective Sources Illustration

Once sound power and “Q” are known, sound pressure at any distance from the unit can be calculated using the following equation:

Lp = Lw - (20 log r) + (10 log Q) - 0.5Where:

Lp = sound pressure

Lw = sound power

r = distance from unit in feet

Q = directionality factor

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

Lp = Lw - (20 log r) -0.5With 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) + 2.5With 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

Results for typical distances and the two most usual cases of “Q” are tabulated in Table 5.

1. Octave band readings are flat dB, overall is A-weighted.

2. Sound pressure data taken at 30 feet (9 meters) from side of unit.

3. Q=2, unit on flat surface with no adjacent wall.

All High Efficiency Trailblazer® models with fully variable speed fans also include a sound reduction mode to allow for reduced-sound operation. Based on a user-settable time schedule, the chiller will enter the reduced noise mode, which will limit the speed of the condenser fans in order to reduce sound levels. This feature is especially helpful in areas that have more stringent sound restrictions during certain times of day. While the lower fan speed may have a slight impact on the maximum unit capacity during hot outdoor conditions, the chiller can be set to automatically override the fan speed restrictions if additional capacity is needed. This way, the unit will always optimize between required capacity and the lowest sound level possible.

Table 14: Pressure Drop Data - Unit Evaporator

NOTE: 1. Full load flow minimum is the minimum allowable flow at full load conditions, and/or for a constant flow system.2. Part Load flow minimum is the minimum allowable flow for a partially loaded unit, which is only applicable a variable flow system. Flow may only be reduced proportionally to load, i.e. a flow reduction of 25% from the design flow rate is only allowable if the chiller load is reduced by 25%.

Figure 47: Spring Isolator

Figure 48: Rubber-in-Shear (RIS) Isolator

Transfer the unit as indicated in the current AGZ-E Installation and Operation Manual, which can be found on www.DaikinApplied.com. In all cases, set the unit in place and level. If ant-iskid pads are used, do not use hold down bolts. If hold down bolts are used, do not use anti-skid pads.

When spring isolators are required, install springs running under the main unit supports. Unit should be installed on blocks or shims at the listed free height. Isolator springs should not be loaded until the installation is complete, then adjust the springs to the vendor listed compression gap for the load point. When securing the isolator, do not over-tighten the mounting bolts. Over-tightening may result in cracking of the cast isolator housing and will have a negative impact on the isolation effect.

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 Dimensions and Weights section, starting on page 29.

Neoprene waffle pads, supplied by customers, should be mounted at the defined mounting point locations along the rail length.

Electrical Data Notes1. Power wiring connections to the chiller may be done with

either copper or aluminum wiring. Wire should be sized per NEC and/or local codes. Wire sizing and wire count must fit in the power connection lug sizing shown in the Electrical Data tables starting on page 49.

2. 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.

3. Recommended fuse sizes are selected at approximately 175% of the largest compressor motor RLA, plus 100% of all other loads in the circuit.

4. Maximum fuse or breaker size is equal to 225% of the largest compressor motor RLA, plus 100% of all other loads.

5. The control transformer is furnished and no separate 115V power is required. For both single and multi-point power connections, the control transformer is in circuit #1 with control power wired from there to circuit #2. In multi-point power, disconnecting power to circuit #1 disconnects control power to the unit.

6. Wire sizing amps is 15 amps if a separate 115V power supply is used for the control circuit.

7. Single-point power supply requires a single disconnect to supply electrical power to the unit. This power supply must either be fused or use a circuit breaker.

8. All field wire lug range values given in the Electrical Data tables starting on page 49 apply to 75°C rated wire per NEC.

9. Must be electrically grounded according to national and local electrical codes.

DANGERQualified, licensed electricians must perform wiring. Electrical shock hazard exists that can cause severe injury or death.

Circuit Breakers Factory-installed compressor circuit breakers are standard on units with single point power supply only. This option provides compressor short circuit protection and makes servicing easier.

Voltage Limitations:1. Within 10% of nameplate rating.

2. Voltage unbalance not to exceed 2% with a resultant current unbalance of 6 to 10 times the voltage unbalance per NEMA MG-1, 2009 Standard Rev. 1-2010.

Electrical Control CenterOperating and equipment protection controls and motor starting components are separately housed in a centrally located, weather-resistant control panel with hinged and tool-locked doors. In addition to the MicroTech® III controller described in the next sections, the following components are housed in the panel:

• Power terminal blocks, multi-point connection standard• Control, input, and output terminal block• Control transformer• Optional disconnect switch (through-the-door handle)• Compressor motor inherent thermal and overload

protection is standard • Optional phase voltage monitor with under/over voltage

and phase reversal protection• Fan contactors with short circuit protective devices.• Optional ground fault protection• FanTrol® fan staging head pressure control system• Power connections are per Table 25

Definitions: 1. Power Block: An electrical device to directly accept field

wiring without any disconnecting means.

2. Disconnect Switch: A molded case switch that accepts field wiring and disconnects main power to the entire unit or each main power supply if the multi-point power supply option is selected. This option does not provide overcurrent protection.

3. Compressor Circuit Breakers: A manually reset circuit breaker for each compressor, providing compressor only short circuit protection and located ahead of the contactor.

4. Control Panel High Short Circuit Current Rating: (Previously known as “withstand rating”). The entire control panel is designed for short circuit current rating as shown in Table 24. In the event of a short circuit, the damage is contained within the control panel enclosure.

Controls Options & Accessories RapidRestore® and Fast LoadingAllows the unit to restart and to reach full load more quickly than standard in case of a power interruption. After a power loss duration of up to 180 seconds, once power is restored, the time for a Trailblazer® chiller to restart is less than 125 seconds with the chiller reaching full load within 220 seconds from power restoration.

Fast Loading Stand-By ChillerGives the system greater response time by starting a stand-by chiller and reaching full load capacity in 115 seconds (assumes conditions require full load capacity).

Hot Gas Bypass (Factory Installed) Hot gas bypass permits unit operation down to 10% of full load capacity. This option includes a factory-mounted hot gas bypass valve, solenoid valve, and manual shutoff valve (models 075-241 only) for each circuit.

High Efficiency Variable Speed Condenser FansHigh efficiency adds variable speed drives to the condenser fans on the chiller. The MicroTech® III controller adjusts the speed of the condenser fans using the VFDs to optimize chiller efficiency and maintain proper head pressure. This feature improves part load efficiency substantially and offers the ability to operate in low ambient conditions down to -10°F. Models 075-241 only.

All High Efficiency Trailblazer® models with fully variable speed fans also include a sound reduction mode to allow for reduced-sound operation. Based on a user-settable time schedule, the chiller will enter the reduced noise mode, which will limit the speed of the condenser fans in order to reduce sound levels. This feature is especially helpful in areas that have more rigorous sound restrictions during certain times of day. While the lower fan speed may have a slight impact on the maximum unit capacity during hot outdoor conditions, the chiller can be set to automatically override the fan speed restrictions if additional capacity is needed. This way, the unit will always optimize between required capacity and the lowest sound level possible.

Low Ambient Control (Factory Installed)Optional fan VFD control allows unit operation down to -10°F (-23°C). Not available on 380 volt (60 Hz) units.

High Ambient Control PanelIncludes an exhaust fan with rain hood, two inlet screens with filters, necessary controls and wiring. Required for operation from 105°F to 125°F (40°C to 52°C) ambient temperature. This panel is included on units with Low Ambient Control, regardless of ambient temperature, to dissipate additional VFD heat.

Power Factor Correction CapacitorsOption to add power factor correction capacitors to improve the chiller’s power factor. Compressor power factor is corrected to approximately 0.95 at standard conditions.

Water Flow Switch (Factory-Supplied) A factory-included thermal dispersion flow switch is necessary to avoid evaporator freeze-up under low or no flow conditions. The flow switch will be installed on the unit (package models) or shipped along with the unit for field installation (remote evaporator models). Terminals are provided in the unit control center for field hook-up of the water flow switch.

Alarm Bell (Field Installed)Field installed and wired to the control panel to provide remote indication of unit alarm condition.

Remote Operator Interface Panel (Field Installed)A remote interface panel, field wired to the unit, providing all the data viewable on the unit’s controller, including alarm clearing and setpoint change capability. See “Intelligent Equipment®” on page 5 for details.

BAS Interface - Open ChoicesTM (Field Installed)The preferred module is shipped loose for field installation on the Microtech® III controller to provide the interface to the following standard protocols:

• BACnet®/IP• Modbus®

• BACnet® Ethernet• LonMark®
