Abstract： With the rapid development of social economy， the problem of energy bottleneck becomes increasingly prominent. It is urgent to find more efficient heating and air conditioning system. Since its inception， ground source heat pump system has been vigorously developed with its characteristics of high efficiency and energy saving. With the advantage of "cutting peak and filling valley"， the cold storage system has always been favored. The advantages of two system are complementary. Taking a practical project as an example， this paper use DeST software to set up building model to simulate the annual load characteristics， then study analysis the characteristics of ground source heat pump combined with cool storage air conditioning system. The following conclusions are drawn： compared with multi connected air conditioning system， the annual operation cost of coupling system is reduced by 40%.

Key Words：Ground source heat pump; Cool storage; DeST; Coupling system

众说周知，空调耗电量约占建筑运行能耗50%～60%，且空调和电力负荷曲线趋势类似，这加剧电力供需矛盾。因此，降低空调能耗是降低建筑能耗的关键，是“削峰填谷”的重要措施。

由于土壤蓄热性能好，故与空气源热泵相比，机组效率更高，无需除霜，没有结霜和融霜的能耗损失，系统稳定，运行费用低。冰蓄冷空调技术，是在电力负荷很低的夜间用电低谷期，采用电动制冷机制冰，用蓄冰设备将冷量贮存起来，电力负荷较高的白天，将贮存的冷量释放出来，一方面平衡电网;另一方面利用峰谷电价差，节约空调系统运行费用[1-2]。

王建华等人对目前复合系统存在的问题提出相应解决措施[3];周瑞芳等人结合实际工程，对地源热泵联合蓄冷系統的经济性进行分析[4];褚赛等人以某工程为例，分析了复合系统的运行策略[5];王俊等人分析了分布式能源高效应用的途径[6];陈明彪从能效和经济性2个方面对跨季节蓄冷技术进行了分析[7]。……
