冷却水对冷水机综合效能的六种影响（The effect of cooling water on the comprehensive efficiency of chiller） In terms of operating expenses, the lower the temperature of condensing temperature and the number of compressors, the lower the cooling coefficient and the smaller the power consumption. According to measure, condensation temperature increase 1 ℃, the refrigerating capacity of the unit power consumption increased about 3% - 4%. So, from this perspective, stabilizing the condensation temperature is good for improving the refrigerating capacity of the chiller. But for this purpose, the following measures should be taken to increase the heat exchange area of the condenser and the water volume of the cooling water; Or increase the heat transfer coefficient of the condenser, but for an air-conditioner cooling system, it is almost impossible to increase the area of the condenser. Increase the amount of water is bound to increase water in the condenser cooling water flow, this will affect the service life of machine, at the same time also increased the cooling water pump power consumption and waste pipe and a series of problems, and the effect is not ideal. Increase cooling tower model, consider a certain amount of surplus coefficient is fair, but if blindly increase the type of cooling tower, in pursuit of lower cooling water temperature is not worth the cost, and the cooling water temperature is limited by the local meteorological parameters. It is practical and effective to improve the heat release coefficient of the cooling water side of condenser, and the effective way to improve the exothermic system is to reduce the fouling heat resistance of the water side, and to treat the cooling water. Water supply for cooling water Water loss of cooling tower, including three parts: evaporation loss, wind loss and pollution loss, namely: Qm = Qe +ve + Qb Type: Qm for cooling tower water loss; Qe is the loss of yanfa water; Qw is the wind blowing loss; Qb is the loss of water discharge.
