How to Choose A Good Air Cooled Chiller?

Air cooled chiller is a kind of refrigeration system which plays an important role in industrial and commercial areas, for example it's widely used for hotels, stadiums, restaurants, schools, large-scale construction, industrial and manufacturing plants, and etc. Its function is to reduce the temperature of the liquid or dehumidify air.

How an industrial air cooled chiller works?

Air cooled chiller has 5 main components: compressor, condenser, fans, expansion valve and evaporator. The cycle starts from compressor. The refrigerant first leaves the compressor with a high pressure, high temperature and then enters the condenser. The condenser – a bundle of horizontal pipes which helps distribute heat. When the refrigerant enters into the condenser, it will run along the horizontal pipes and transfer its thermal energy into the ambient air stream which is forced by the fans on top. Next the refrigerant enters the expansion valve --- this expands the refrigerant before it enters the evaporator. Evaporator – This is where the chilled water is produced and the heat from the warm return “chilled water” is extracted, to be sent to the condenser.

How to choose a good air cooled chiller? Which characteristics it has?

A high quality air cooled chiller with the following features:

- Flexible modular combination

- Central control module

- Multiple protection design, high-low pressure protection, overload, open phase/reverse phase, water-break and anti-freezing protection

- Running assurance with independent systems design

- High efficiency shell and tube evaporator

- Anti-corrosion painting

- World famous compressors

If data is used to filter products, then the relevant indicators of good air cooled chiller can refer to the following data:

- Rated cooling capacity between 60 to 200 KW.

- Power Supply: 3N~380V 50Hz

- Qty of compressor about 2-6 pcs

- Water pressure drop of evaporator is 50-60 kPa

- Noise ＜ 70 dB(A)

- Type of refrigerant is R22 or R410A

- Cooling: Water inlet temp 12°C; Water outlet temp 7°C; Ambient temp 35°C.

- Heating: Water inlet temp 40°C; Water outlet temp 45°C; Ambient DB=7°C, WB=6°C.
