中央空调在高层建筑中是耗电大户,其耗电量约占建筑物总耗电量的60%。因此,对中央空调系统进行适当的节能技术改造,降低能耗,显得尤为重要。文章着重探讨在中央空调机组运行过程中,利用变频器,将温差控制器在中央空调冷冻泵、冷却泵进行节能改造的应用,并阐述其原理方法及节能效果。 Central air conditioning in high-rise buildings is a large power consumption, its power consumption accounts for about 60% of the total building electricity consumption. Therefore, the central air conditioning system for energy-saving technological transformation, reduce energy consumption, it is particularly important. This article focuses on the application of frequency converter in the operation of central air conditioning unit, energy saving of temperature controller in central air conditioning refrigeration pump and cooling pump, and expounds the principle and method and energy saving effect.
