Low Power Consumption 390kw/520KW/650kw/1040kw 50ton/70tons/90ton/300tons Air Cooled Water Chiller

Air-cooled scroll water chiller is an efficient refrigeration equipment, which uses scroll compressor and air cooling technology to provide cold water (usually 7-12℃ outlet water temperature) for buildings or industrial processes through refrigerant circulation. The unit has high integration, no need for additional cooling tower, and is suitable for small and medium-sized refrigeration demand scenarios.

Key Features and Benefits

Core components

Scroll compressor: The refrigerant is compressed through the meshing of scroll plates, with stable operation and low noise.
Air-cooled condenser: the high-temperature and high-pressure gas refrigerant is condensed into liquid by forced heat dissipation of the fan.
Evaporator: Liquid refrigerant absorbs heat in the water system here to realize cold water output.
Electronic expansion valve: accurately control refrigerant flow and improve energy efficiency.

Working principle:

The refrigerant is compressed in the compressor → the high-temperature gas enters the condenser to dissipate heat → the liquid refrigerant is depressurized by the expansion valve → it absorbs heat and evaporates in the evaporator → it returns to the compressor for circulation.

Applications

Product advantages and characteristics

High efficiency and energy saving: IPLV value is above 4.5, and the energy efficiency ratio of part load is high.
Low noise design: scroll compressor+variable frequency fan, noise ≤75dB(A).
Intelligent control: Support remote monitoring of the Internet of Things, and automatically adjust the running state.Modular combination: multi-unit parallel design, flexible expansion.

Application scenario

Commercial buildings: central air conditioning systems for office buildings, shopping malls and hotels.
Industrial cooling: cooling of injection molding machine, laser equipment and pharmaceutical process.
Regional refrigeration: data centers, hospitals and other places that need year-round refrigeration.
