And after the redundant solar energy is stored in the soil, the heat of the soil source can be continuously supplemented, and the defect that the efficiency of a single ground source heat pump is gradually reduced along with the prolonging of the service life is avoided. The soil source is continuously supplemented with solar energy, the longer the service life is, the higher the long-term efficiency is, and the temperature of the ground source can meet the requirement of direct heat supply in about 3 years, so that direct heat supply of a heat pump is separated, and the consumption of traditional energy sources is further reduced. With the prolonging of the service time, the solar energy heat pump can completely get rid of the traditional energy sources, and can supply heat all weather by only solar energy (including the solar energy part stored in the soil source), thereby obtaining the best matching effect of the solar energy and the ground source.
