摘　　要：传统地下水源热泵(GWHP)对地下水储存的冷量利用十分有限。结合温湿度独立控制空调系统优点,构建了一种地下水分级冷却的地源热泵(GGWHP)空调系统,并搭建GGWHP空调系统实验装置。实验研究新风量、地下水温度和地下水流量对GWHP和GGWHP空调系统供冷性能的影响。实验结果表明:GGWHP空调系统的能耗低于GWHP空调系统。新风量从305 m^(3)/h增加到1 835 m^(3)/h, GGWHP空调系统与GWHP空调系统相比,能耗节省4.78%;GGWHP空调系统的性能系数(COP)减少0.89。地下水温度从17℃增加到21℃,GGWHP空调系统与GWHP空调系统相比,能耗节省8.41%;GGWHP空调系统的COP减少1.02。地下水流量从550 kg/h增加到1 320 kg/h, GGWHP空调系统与GWHP空调系统相比,能耗节省8.59%;GGWHP空调系统的COP增加1.03。The conventional groundwater source heat pump(GWHP)has very limited utilization of cooling capacity for groundwater storage.Combining the advantages of independently controlling air conditioning systems based on temperature and humidity,a graded-cooling groundwater source heat pump(GGWHP)air conditioning system was been constructed,and the experimental devices of GGWHP air conditioning system was built.The experiments of the effects of fresh air volume,groundwater temperature and groundwater flow rate on the cooling performance of GWHP and GGWHP air conditioning systems were conducted.The experimental results indicate that the energy consumption of GGWHP air conditioning system is lower than that of GWHP air conditioning system.The fresh air volume increased from 305 m 3/h to 1835 m 3/h,the energy consumption of GGWHP air conditioning system decreased by 4.78%compared to GWHP air conditioning system,and the coefficient of performance(COP)of GGWHP air conditioning system decreased by 0.89.The groundwater temperature increased from 17℃to 21℃,the energy consumption of GGWHP air conditioning system decreased by 8.41%compared to GWHP air conditioning system,and the COP of GGWHP air conditioning system decreased by 1.02.The groundwater flow rate increased from 550 kg/h to 1320 kg/h,and the energy consumption of GGWHP air conditioning system decreased by 8.59%compared to GWHP air conditioning system,and the COP of GGWHP air conditioning system increased by 1.03.
