We know that the performance of the chiller is closely related to the evaporation temperature and condensation temperature. Today, East Star Xiaobian and we look at the condensation temperature on the performance of cold water chiller what are the effects.
    The change of condensation temperature is mainly caused by different regions, seasonal changes or different cooling methods. When analyzing the effect of condensing temperature on the performance of the refrigerant, it is assumed that the evaporation temperature remains unchanged:
    1, the condensation temperature of the chiller, then the condensation pressure will increase with the increase of the condensing temperature, the exhaust temperature of the compressor will also rise.
    2, the unit cooling capacity of the chiller is reduced, the suction volume is constant, and the refrigerating capacity per unit volume decreases.
    3, if we ignore the compressor volumetric efficiency changes, then the refrigerant mass flow constant, then all the cooling capacity of the refrigerator must be reduced, the theoretical power of the compressor must increase.
    Therefore, when the evaporation temperature of the chiller unchanged, when the condensation temperature high, with a cold water machine, it will reduce the refrigerating capacity, power consumption will also increase, it is because of this, so the refrigeration coefficient of water chiller directly reduce. But if the temperature is reduced, the change will be the opposite. Do you understand now?
