Reasons for the high condensation temperature of the chiller

Many friends have encountered the problem of high condensing temperature of the chiller host. Today, I will analyze the reasons for the high condensing temperature of the chiller host. The high condensing temperature of the chiller host is mainly due to several problems in the cooling water system. .

1. Fouling of the heat exchanger of the unit.

2. The amount of cooling water is too small. Its performance is that the pressure difference between the inlet and outlet water of the main engine decreases, while the temperature difference between the inlet and outlet water increases. And the operating current of the chiller cooling water pump may also drop

3. The cooling efficiency of the cooling tower is insufficient. It is manifested as a decrease in the temperature difference between the inlet and outlet water of the cooling tower or the approaching temperature does not meet the design requirements

Possible causes: scaling or aging of tower packing, abnormal water distribution device makes uneven water distribution, abnormal fan and transmission device resulting in insufficient circulating air volume, poor ventilation environment around the tower, poor water balance between tower and tower leading to heat exchange Insufficient unevenness and so on.
