Energy-saving analysis of frequency conversion in air conditioning cooling water systems

Establishes the mathematical models of refrigerator, pump and cooling tower in cooling water systems, and studies the effects of the frequency conversion of cooling water pump and cooling tower fan on the energy consumption of cooling water system. The results show that when the cooling water pump is adjusted to the working point of maximum energy saving, the frequency conversion of cooling water pump is of positive significance to reduce the energy consumption of the refrigeration system, and the frequency conversion of cooling tower fan can not effectively reduce the energy consumption of the refrigeration system.
