| Abstract: | Based on the load characteristics of the actual project in cold area,the ground-solar source heat pump coupled system with auxiliary heat source is designed.The annual cost method is used to analyze the economy of the system,and the optimal allocation ratio of two heat sources for combined heating in winter is obtained.The thermal equilibrium situation of the soil all the year round is calculated.Aimed at the thermal equilibrium of soil,the area of solar collector is calculated.The operation data of the project show that the system runs steadily,the thermal equilibrium of soil behaves well,and the energy-saving benefits are remarkable. |
