Experiment on the Solar Energy and Buried Pipe Heat Pump Joint Heating

The authors had researched the heat accumulation capacity of solar energy system and the heating capacity of the solar-ground source heat pump system. The solar-ground source heat pump system was built for 220 square meters of the building. Considering winter heating load as building energy demand,we built the solar-ground source heat pump system. The experimental results suggest that,the soil temperature has been raised 3 ℃,and the heating capacity of heating system has been improved by8%,it is feasible to use this system in heating seasons.
