摘　　要：介绍并给出了浴室废水余热回收热泵热水系统模型,利用此污水源热泵可回收城市公共浴室废水中存在的大量废热能,减少城市余热的排放,节省了一次能源消耗。通过对该热泵热水系统模型的分析,得到了系统循环各部件（热水箱、混水器、淋浴过程、热泵）的流情况、系统效率、系统损失系数与废水进出口温度、热泵性能系数等因素的关系曲线。与普通电加热形式的热水系统的效率进行比较,得出该余热回收热泵热水系统效率是普通电加热热水系统的1.5~2倍,是理想的供热水设备。The bathroom waste heat recovery heat pump system model is given.Take advantage of this water source heat pump,plenty of waste heat which exits in urban public bath waste water can be recycled.Urban heat emissions is also reduced.The relation curves of exergy flow of system components（i.e.,hot tank,water to water jet,shower process,heat pump）,exergy efficiency of system,exergy loss coefficient of system and import and export of waste water temperature,heat pump coefficient of performance are analyzed by exergy analysis of this hot water system model.Then,exergy efficiency of this system is compared with electric heating hot water system under the premise of the same shower temperature.The exergy utilization of this waste heat recovery heat pump hot water system is higher.
