Abstract :
A system of Solar-Ground Coupled Heat Pump with Energy Storage (SGCHPES) was built with space heating, air conditioning and hot water. The energy storage comprised Seasonal Storage in soil and Phase Change Heat Storage in the SGCHPES system. The operation modes of the SGCHPES system and the energy use in solar and ground energy were obtained in different seasons and different operation modes. Based on TRNSYS platform, the solar & ground energy combination and match use, and its contribution to the SGCHPES system were studied. The seasonal storage in soil and its energy balance were analyzed. Experiments were also carried out in a SGCHPES demonstration project.
