Taking a large and medium-sized comprehensive gymnasium in Hangzhou as an example, the optimization of the operation strategy of the ice cool storage air conditioning system is discussed. The operation strategies of the ice cool storage system under 85%, 75%, 50% and 25% load rates are studied, and the operating costs of the traditional chiller priority control strategy and optimal operation strategy are compared. The results show that the optimal operation strategy under different load rates can achieve the effect of “peak load shifting”, and save 20%, 22%, 27% and 21% of the daily operating costs, respectively. The feasibility and effectiveness of the optimized operation strategy are verified, which provides a basis for the application of the ice cool storage system to comprehensive gymnasium.
