Liquid refrigerant is removed by drying the water filter, impurities, enters the expansion valve is throttled pressure, a low temperature and low pressure liquid refrigerant, vaporized in the evaporator. Gasification process to absorb the liquid latent heat of vaporization and different fluid pressure, the saturation temperature (boiling point) is different, the lower the pressure, the lower the saturation temperature. For example, 1kg of water at an absolute pressure 0.00087MPa, saturation temperature of 5 ℃, the need to absorb the heat of vaporization 2488.7KJ; 1kg ammonia under a standard atmospheric pressure (0.10133MPa), the need to absorb vaporization 1369.59 KJ heat, the temperature can reach -33.33 ℃. Therefore, if the creation of a low pressure condition, it can be used to obtain low temperature of the steam required. So the principle gasification process chilled water absorbs heat, so that the chilled water temperature decreases (generally reduced to 7 ℃). Refrigerant absorbs heat in the evaporator, it becomes superheated steam temperature entering the compressor to repeat the cycle. Vapor compression refrigeration system consists of water-cooled and air-cooled.
