The power consumption of air-conditioning systems accounts for over 40%~50% of the total building energy which in turn, takes over 25% of total electrical power consumption in the nation. The disadvantage of thermal storage is the load consumption may exceed a tolerable range if chilled water supply temperature has not controlled in the on-peak demand. This article takes optimal control with chilled water supply temperature to reduced load consumption by the cooling load. Experimental result indicates a decrease of 15% of power consumption with optimal control in spring and fall. In winter, the optimal control decrease of 30% of power consumption.
