Cold water machine, in the industry is divided into air-cooled chiller and water cooled chiller [1] two kinds, cold water machine on the temperature control is divided into low temperature cold water machine and normal temperature cold water machine, general control at room temperature in the range of 0-35 degrees. The temperature control of the cryogenic machine is generally in the range of 0 to minus 45 degrees.
Air cold water chiller
Introduce：
Cold water machine the refrigerant cycle system of liquid refrigerant in the evaporator absorbs the heat in the water and began to evaporate, the ultimate formed certain temperature difference between refrigerant and water, liquid refrigerant also completely evaporate into a gas compressor suction and after compression, gaseous refrigerant absorbs heat through the condenser, condensed into liquid, through the thermal expansion valve throttle into low temperature low pressure refrigerant entering the evaporator, after completing the process of refrigerant cycle.
