In this paper, an economic mathematics model was founded to analyze the economic technology properties of an ice storage air conditioning system of Chao Yang plaza at Beijing. The Power input of the ice storage system of Beijing Chao Yang Plaza air conditioning engineering was compared with that of a conventional air conditioning system if it used for the engineering. The impaction of the operation strategy to the economic technology properties of the ice storage air conditioning system was also investigated. The operating cost of ice storage system is lower than that of an ordinary air conditioning system, and the difference of time-shared electrovalence is bigger, the profit is more. The operating strategy of a priority of release cold quantity is should be adopted in order to reduce the operating cost.
