摘要
针对目前能源紧缺及热泵热水器的发展现状,搭建了循环加热污水源热泵热水器实验台,维持蒸发侧污水源进水温度、冷凝侧和蒸发侧水流量恒定,测量记录保温水箱水温从15℃升高到55℃过程中的加热区间能耗、进出水温差、压缩机吸排气压力、电功率等参数。数据分析得出,系统平均能效比达到3.73,具有较好的节能性。
According to the energy shortage and the development of heat pump heater,the experimental study was carried out on the performance of sewage source heat pump water heater with circulating heat function.Maintaining the evaporation side sew-age inlet temperature,voltage,the condensation and evaporation side water flow constant,measuring and recording system pa-rameters such as energy consumption of heating interval,the temperature difference of inlet and outlet water,the suction and dis-charge pressure e of the compressor,electric power,with the water tank temperature increased from 15 ℃to 55 ℃.The results show that the average COP of system reaches 3.73,which show that this type of heat pump water heater has better energy saving performance.
