Energy saving analysis
Summer operation: Because the outdoor temperature in summer is higher than the chilled water inlet temperature, the unit uses a compressor for refrigeration, which is the same as the conventional air-cooled screw machine.
Transition season: when the outdoor temperature is lower than the chilled water inlet temperature of 2 ° C, open the natural cold precooling mode, at this time the unit adopts natural cooling and compressor refrigeration, and the advantages of the natural cold screw unit are gradually revealed.
Winter operation: when the outdoor temperature is lower than a certain value, the unit can achieve 100% natural cooling, and all cold capacity depends on the external cold source, without opening the compressor, compared with the conventional natural cold screw unit, operation and maintenance is more energy saving.
