Abstract：
Taking a groundsource heat pump project in Chongqing as an example, explores its operating characteristics with measured data from energy consumption monitoring system and ground temperature monitoring system. Analyses the parameters variation, including the inlet and outlet water temperature of the unit, energy consumption, COP of the heat pump unit and system, energy efficiency ratio of cooling water system and the soil temperature, and finds the problems of soil heat accumulation and low system efficiency.
Keywords:hot summer and cold winter zone, groundsource heat pump, operating characteristic, heat accumulation, monitoring
