 According to the construction load characteristics of Qingdao Science and Technology Museum, the distribution of energy around the project and the operation time, this paper presents the configuration ideas of the cold and heat source of the combined ground-source heat pump system (gas boiler for auxiliary peak-shaving heating in winter, and chiller plus cooling tower system for auxiliary cooling in summer), and analyses the application rationality from the aspects of initial investment, operating costs, static payback period, etc. In order to reduce the energy consumption of the system, this paper carries out a preliminary study on the control strategy of the compound ground-source heat pump according to the dynamic load of the Qingdao Science and Technology Museum and the operating characteristics of the units, with a view to provide guidance for the application of the compound ground-source heat pump system to actual projects.
