水冷开放式工业冷水机组选型参数

Water cooled open industrial chiller unitWorking principle





The high-pressure and high-temperature gas from the compressor enters the condenser, and the heat is carried to the outside by the cooling towerOperating substancesBecoming a high-pressure room temperature liquid, the high-pressure room temperature liquid enters the expansion valve throttling mechanism for pressure reduction, and some of the liquid flashes into vapor. These low-temperature and low-pressure gas-liquid two-phase mixtures enter the evaporator, where they exchange heat and cool with the high-temperature hot water of the customer's industrial equipment. The medium inside the evaporator becomes vapor and returns to the compressor for re compression, completing a cycle. The chiller unit continuously exchanges heat and cools, supplying mechanical equipment and products for cooling.
