地下水分级冷却的地源热泵供冷性能实验
Experiment on Cooling Performance of Graded-cooling Groundwater Source Heat Pump
摘要
Abstract
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 m3/h to 1 835 m3/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 1 320 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.关键词
