Features and Benefi ts

IntroductionUsing the leading high-effi ciency ermetic scroll compressor and evaporator technology, Koolman provides you a stable, reliable and highly effi cient operation. Matched with a large variety of fan coils of different sizes it can be widely used in top grade apartments, luxury villas, offi ce buildings, small-sized restaurants, retail stores and hotels to create a comfortable and delightful indoor environment.

State-of-the-art appearanceKoolman boasts of its state-of-the-art appearance. The contemporary appearance, designed by expert designers, will be naturally integrated with the surrounding environment and will defi nitely display your prominent taste.

Small footprintAs a result of the particular slim design (standard type is 500mm thick while mini type is only 393mm thick), the unit can be installed directly on the veranda, rooftop or ground without the need to have aplant room.

Available optionsUnit with pressurized water tank is available to meet various requirements.

Noise levelKoolman uses low noise fans and components to achieve its low noise evel.

Easy installationEach chiller has factory charged oil and refrigerant for reducing fi eld labor and materials costs. All units are factory run tested. Only power supply and water piping are required to be connected on the jobsite.

Environmentally friendly refrigerantAll models are charged with R410A refrigerant.

Free of Cooling TowerHeat dissipation in the way of air cycle eliminates the need for cooling water tower. Thus, not only does it save the cost and space for cooling tower it also eliminates water shortage concerns.

Mechanical Specifi cations

GeneralKoolman air-cooled liquid chiller is designed to couple with fan coil units and air handling units for residential and light commercial air conditioning applications. Units are composed of scroll compressor (s), plate type evaporator, fi nned-coppertube and aluminum condenser, axial fan assembly, expansion valve, four-way reversal valve (heat pump only), indoor Cooling/Heating control switch, water fl ow switch, fi lter dryer, sight-glass, built-in water pump, galvanized sheet metal housing with powder paint and factory mounted controls. Optional fi ttings include pressurized water tank system.

CompressorDepending on capacity range, units come with single or double scroll compressors to cater for changing demand and effi cient part load operations.

EvaporatorEvaporator is a compact brazed plate heat exchanger with AISI 316 stainless plates and adapters. A 20-mesh strainer is installed at the water inlet to protect the evaporator and unit against fouling. The strainer (factory provided, fi eld installed) can be removed for cleaning.

HousingAll parts are fabricated to precision by state-of-the-art CNC machines. The frame design allows all panels to be removed for service without affecting the structure of the unit. The panels are made of galvanized steel plate with powder paint. All panels are internally insulated with single layer foam cell in order to reduce noise and vibration.

Water pumpPump is Rotodynamic pumps and adopts a mechanical shaft seal. Motor is fan cooled (TEFC), 2-pole induction type. Pump is installed in the unit to save installation space and also to reduce noise level.

Controls and protection devicesThe controller contains all the basic electrical protection devices including electromagnetic switches, relays and current overload protectors. The automatic control devices consist of high and low pressure switches, thermostatic and anti-freeze cutouts, which improve and protect the unit's normal operation.In addition, the preset low temperature protection command can start the machine automatically to protect the water pipes from freezing.

LCD microprocessor-based controllerPrecise temperature control of inlet chilled water, operation modes and system protection are provided by the long-range controller. In addition, the password can be set and any abnormal condition will be monitored and captured to facilitate quick repair and normal operation. In addition, the interlocking function of the two-way valve is available.

Air-cooled condenserThe unit comes with air-cooled fi n-tube U or V shaped condensers. Copper tubes are of the 3/8" diameter, seamless type. Fins are aluminum with effi cient Wavy fi n. Copper tubes are expanded mechanically to bond with the fi ns for effective heat transfer. Light-weight axial fl ow fan(s) is (are) driven by high effi ciency, low speed, low noise motor(s) to ensure quiet and reliable operations.

Description of the principle of the pressurized water tank:1. In order to avoid the pipe cracking due to the system over pressure resulting from the change of

ambient temperature and also to avoid the water hammer in the pipes, a pressurized water tank shall be installed for system.

2. In order to avoid the excessively high or low pressure in the pipe, an automatic feed water valve and an automatic drain valve are included in the pressurized water tank. The feed water pressure can be adjusted based on the fi eld situation.

3. An open expansion tank shall be installed at the highest position of system.

Note: the automatic exhaust valve shall be set at the highest point of the piping

Water pressure drop

To measure the water pressure difference between the water inlet and outlet of the unit (including

pump), pump head at a particular water flow rate may be read off from the pump head curve.

Refer to curves to design piping system for standard models with pumps.

The inner water pressure drop of the unit without a pump (the pump is installed outside of the

unit) should basically follow the graphs shown in the Water pressure drop curve section. Refer to

curves to design piping system for models without pumps.

Water fl owThe chilled water fl ow through the unit shall be rated between the upper and lower limit listed

in the table. If the chilled water fl ow is below the lower limit, the discontinuous water fl ow will

reduce the evaporator heat transfer and make the expansion valve out of control or exceptional

low-pressure shutdown. Contrarily, the inner parts of the evaporator will be eroded if the water

fl ow is higher than the upper limit.
