Abstract
The solar-ground source heat pump (SGSHP) heating system is proposed based on the analysis of advantage and disadvantage of Solar Heat Pump (SHP) and ground source heat pump GSHP. In this paper the operation mode and energy-saving effect were researched. Through the experiment of SHP, GSHP and SGSHP in a whole heating season?shown that operation mode of SGSHP is feasible. By analysis of experimental data, comparing the performance of GSHP with that of SGSHP, it indicted that the average COP of heat pump of SGSHP was 4.33 and total system COP of SGSHP was 3.98 in the whole heating season. Integrated performance was better than any other system.
