Background
The energy market at present faces huge opportunities and challenges, and energy conservation and carbon reduction become a focus of attention of the whole society. The soil source heat pump extracts heat from underground soil in a heating season through a device for converting low-grade geothermal energy in the soil into high-quality thermal energy through the heat pump, and the device is used for heating users. When the temperature is required to be reduced in non-heating seasons, heat is transferred to underground soil. The ground source heat pump can stably operate through heat taking and heat release in heating seasons and non-heating seasons.

Therefore, the solar energy is used as an auxiliary heat source to relieve the problem of uneven cold and hot loads of the soil source heat pump used in the alpine region.
