Hybrid ground-source heat pump system design of a hospital building in Chongqing

Taking a hospital in Chongqing as an example, based on the dynamic load simulation, presents that the annual thermal balance of underground soil is the key problem in hybrid ground-source heat pump system design. In view of cooling and heating load difference between summer and winter, summarizes the ground-source heat pump system design scheme which designs the ground heat exchanger based on winter heating load, and the cooling tower as an auxiliary in summer. Discusses the heat and cold sources energy-saving operation programs based on the above design ideas.
