Ways to improve the efficiency of the
chiller: reasonably select the capacity of the chilled water, or adjust the operating load of the chiller equipment. Practical application shows that under the condition of ensuring the safe operation of the refrigeration equipment, the chiller operates at 70%-80% load. , the power consumption per unit cooling capacity is the smallest. Reduce the condensing temperature of the chiller: On the premise of meeting equipment safety and production needs, try to increase the evaporating temperature and reduce the condensing temperature. Therefore, there should be a certain margin when choosing the matching cooling tower when the chiller is initially installed, or the operation status of the separation pump and the cooling tower should be considered comprehensively, and the original cooling tower water system should be upgraded to ensure the cooling water. cooling efficiency.
Avoid and reduce pipe fouling to improve the heat exchange efficiency of the condenser and evaporator: when the chiller runs for a long time, if the water treatment of the cooling water and chilled water in the system is not done properly, calcium bicarbonate and magnesium bicarbonate will produce carbonic acid Calcium and magnesium carbonate will accumulate on the pipe wall of the pipe or heat exchanger, which will reduce the thermal conductivity, affect the heat exchange efficiency of the condenser and evaporator, and increase the power consumption of the equipment. In this case, in addition to using water treatment technology, It can also periodically descale and clean the water system pipes and cooling towers to improve heat exchange efficiency.
