In 1998, Time magazine named Dr. Carrier oneof its 20 most influential builders and titans ofthe 20thcentury.

Features

Benefits

Quiet operation

Economical operation

Increased energy efficiency at part load- The refrigerant circuit includes several compressors connected in parallel. At part load, around 99% of the operating time, only the compressors that are absolutely necessary operate. - The electronic expansion device (EXV) allows operation at a lower condensing pressure (EER, COP and ESEER optimization).- Dynamic superheat management for better utilization of the evaporator heat exchange surface.- Defrost cycle optimization (30RQ).Reduced maintenance costs- Maintenance-free scroll compressors.- Fast diagnosis of possible incidents and their history via the Pro-Dialog Plus control.- HFC-410A refrigerant is easier to use than other refrigerant blends.

The new generation of Aquasnap Puron liquid chillers/air-to-water heat pumps was designed for commercial (air conditioning of offices, hotels etc.) or industrial (low-temperature process chillers etc.) applications.

Standard unit with hydronic module including all necessary hydronic components, easy and fast installation to save time, space and money.Low operating sound with no intrusive low-frequency noise, creates a better working/living environment.Environment sound refrigerant HFC-410A of zero ozone depletion potential.Electronic expansion valve (EXV) utilization, several compressors connected in parallel lead to more economical operating cost.Exceptional endurance tests ensure superior reliability for minimizing chiller down-time.

Compressors- Low-noise scroll compressors with low vibration level.- The compressor assembly is installed on an independent chassis and supported by anti-vibration mountings.- Dynamic suction and discharge piping support,minimizing vibration transmission (Carrier patent).Condenser section- Vertical condenser coils.- Protection grilles on anti-vibration mountings to protect the heat exchanger against possible shocks.- Low-noise latest-generation Flying Bird IV fans (Carrier patent) , made of a composite material are now even quieter and do not generate intrusive low-frequency noise.- Rigid fan installation for reduced start-up noise (Carrier patent).

Environmental care

Superior reliability

4

Easy and fast installation

State-of-the-art concept- Cooperation with specialist laboratories and use of limit simulation tools (finite element calculations) for the design of the critical components, e.g. motor supports, suction/discharge piping etc.Exceptional endurance tests- Corrosion resistance tests in salt mist in the laboratory.- Accelerated ageing test on components that are submitted to continuous operation: compressor piping,fan supports.- Transport simulation test in the laboratory on a vibrating table.

Ozone-friendly HFC-410A refrigerant- Chlorine-free refrigerant of the HFC group with zero ozone depletion potential.- High-density refrigerant, therefore less refrigerant required.- Very efficient - gives an increased energy efficiency ratio.Leak-tight refrigerant circuit- Brazed refrigerant connections for increased leaktightness.- Reduction of leaks due to reduced vibration levels and elimination of capillary tubes (TXVs).- Verification of pressure transducers and temperature sensors without transferring refrigerant charge.

Integrated hydronic module - Centrifugal fixed speed water pump.- Single or dual pump (as required) with operating time balancing and automatic changeover to the back-up pump if a fault develops.- Water filter protecting the water pump against circulating debris.- High-capacity membrane expansion tank ensures pressurization of the water circuit.- Thermal insulation and frost protection down to -20 , using an electric resistance heater.Physical features- The unit has a small footprint and a low height (1330 mm) allowing it to blend in with any architectural styles.- The unit is enclosed by easily removable panels, covering all components (except condensers and fans).Simplified electrical connections- A single power supply point without neutral.- Main disconnect switch with high trip capacity.- Transformer for safe 24 V control circuit supply included.Fast commissioning- Systematic factory operation test before shipment.- Quick-test function for step-by-step verification of the instruments, electrical components and motors.

Pro-Dialog Plus combines intelligence with operating simplicity. The control constantly monitors all machine

parameters and precisely manages the operation of compressors, expansion devices, fans and of the evaporator

water pump for optimum energy efficiency.

Pro-Dialog Plus Control

User-friendly interface

The new backlighted LCD interface includes a manual control potentiometer to ensure legibility under any lighting conditions. The information

is in clear text and can be displayed in English.

Unit uses intuitive tree-structure menus, similar to the Internet navigators. They are user-friendly and permit quick access to the principal

operating parameters: number of compressors operating, suction/discharge pressure, compressor operating hours, set point, air temperature,

entering/leaving water temperature.

A quick test of all unit components and control points to verify the correct operation of every switch, circuit breaker, contactor etc. at the start

of the chiller.

Real-time monitor all the operation parameter, and alarm when necessary.

Control system is facilitated with RS485 serial communication port for remote diagnosis or special diagnosis tools.

Powerful diagnostics

Password protection in case of mishandling.

Unit is protected against: compressor reverse, low chilled water temperature, high/low refrigerant pressure, excessive current, motor overload.

Sufficient safety measures

Master/slave control of two chillers operating in parallel with operating time equalization and automatic changeover in case of a unit fault.

Communication with other Building Management System (BMS) by selecting BacNet/J-Bus/LonTalk gateway.

Group control

Unit provides different control mode including LOCAL/REMOTE/CCN.

Remote control function including: Unit ON/OFF, dual set point control, demand limit control, user safety interlock, water pump control,

operation indication, circuit alarm and alert etc.

Enable automatic reset of leaving water temperature according to return water temperature or outside air temperature to ensure optimum

energy efficiency.

Control algorithm prevents excessive compressor cycling and permits reduction of the water quantity in the hydronic circuit (Carrier patent).

Automatic compressor unloading in case of abnormally high condensing pressure. If an abnomal incident occurs (e.g. fouled condenser coil,

fan failure), Aquasnap continues to operate, but at reduced capacity.

Minimum Water Loop Volume

Maximum Water Loop Volume

For better control of leaving water temperature, the water loop minimum capacity is given by the formula: Capacity = CAP (kW) × N Liters

CAP: Unit’s nominal cooling capacity

It is often necessary to add a buffer water tank to the circuit in order to achieve the required volume. The tank must itself be internally baffled in order to ensure proper mixing of the liquid (water or brine). Refer to the examples below.

The expansion tank of the unit with hydronic module limits the maximum water volume, refer to below sheet:
