Title: Case Study on GSHP System for Single Residential in Heating Season
Abstract: In this paper,the monitoring on the operating parameters of heating of ground source heat pump system in single family houses in winter in Shanghai was carried out,and such indicators as heat absorption per meter of buried pipe of ground heat exchanger,performance coefficient COP of units and systems and system energy-saving rate were analyzed.The results shown that outlet water temperature of ground heat exchanger and heat transfer temperature difference were relatively stable,and heat absorption per meter of buried pipe was 27~32 W/m,system performance coefficient COP was greatly influenced by partial load rate,and COP fell within the range of 3.3~3.9 during the whole testing period.To achieve comfort,the energy that ground-source heat pump saved was 31.0% higher than that of air-source heat pump,therefore the energy-saving effect was rather apparent.
