摘要(Abstract)：

提出了一种空气/水复合热源热泵型空调器,冬夏使用中在采用空气作为热源同时可以回收利用家庭废水的低品位热能。运用热力学原理研究了夏季在不同新风比、不同室内温度时机组制冷系数随冷凝水回收后温度变化而变化情况;分析了机组冬季制热回收废水缓解室外换热器结霜的机理,研究了采用R22和R407C工质时回气温度和蒸发压力随回收废水量和出水温度的变化。结果表明,采用空气/水作为热泵型空调器的复合热源,能够提高机组夏季制冷循环的制冷系数,冬季制热时有利于延缓室外换热器结霜、改善冬季制热性能。
A heat pump air-conditioner which has multiple heat sources of air and family wastewater is presented.The low-grade heat of wastewater in the family can be utilized while air is used as the heat source.It is studied that the changes of the conditioner refrigeration coefficient vary with the utilized condensing water temperature and the conditioner is operating on different fresh air ratio and in-door temperature.The relieving frost mechanism of the operating conditioner with utilizing waste water during winter is analyzed,and then the temperature changes of the refrigerator return and the changes of evaporation pressure vary with the flow of waste water and outlet temperature.It is indicated that in summer the conditioner refrigeration coefficient will increase and in winter the frosting of the out-door heat exchanger will be relieved and the heating performance will be improved by utilizing air and family wastewater as multiple heat sources.
