Energy saving analysis and discussion of cooling towers of central air conditioning systems

With the development of the central air conditioning energy saving technology, energy saving schemes and control strategies of chilled water system tend to unify, but the energy saving space of the cooling tower in cooling water side remains controversial. Striving to further improve the energy saving ratio of central air conditioning systems, from the aspects of theory and practice, expounds the influences of operating numbers of cooling towers and operating frequency of fans on the performance of chillers and the energy consumption of the whole central air conditioning system. Concludes that through the optimization control of cooling towers, the power saving ratio of the central air conditioning system increases by 5%.
