| Abstract | A demonstration project of Solar-Ground Coupled Heat Pump with Seasonal Storage (SGCHPSS) was set up and a data acquisition system was developed. In the SGCHPSS system, the abundant solar energy in summer was stored into the underground soil, in order to rise the soil temperature as the heat source for the Ground Coupled Heat Pump (GCHP), and to enhance its efficiency. That realized solar energy transfer utilization through the energy inter-seasonal storage. The phase change heat storage was designed to store and balance solar energy use in the short-term. Primary experiment on the SGCHPSS system was obtained, including the solar collection temperature, solar collection power and storage power. |
