摘　　要：提出一种兼具供暖与提供生活热水的户式太阳能联合污水源热泵系统,根据TRNSYS仿真结果,分析联合系统在北京地区住宅的运行性能以及经济性。供暖期平均室内温度为21.5℃,供热质量良好。室内温度低于18℃的时间仅占供暖期的0.06%。供暖期内,供暖热水平均供水温度为40.9℃,内水箱生活热水平均出水温度为38.2℃。将燃气热水炉系统、电热水炉系统作为对比方案。联合系统、燃气热水炉系统、电热水炉系统的费用现值分别为10926.3、19275.4、13255.5元。联合系统的费用现值最小,经济性最好。A household solar combined sewage source heat pump system with both heating and domestic hot water supply is proposed.According to the TRNSYS simulation results,the operation performance and economy of the combined system in Beijing area housing are analyzed.The average indoor temperature during the heating period is 21.5℃,and the heating quality is good.The time when the indoor temperature is lower than 18℃only accounted for 0.06%of the heating period.During the heating period,the average water supply temperature of heating hot water is 40.9℃,and the average outlet temperature of domestic hot water in the inner water tank is 38.2℃.The gas water boiler system and the electric water boiler system are taken as comparison schemes.The cost present values of the combined system,gas water boiler system and electric water boiler system are 10926.3 yuan,19275.4 yuan and 13255.5 yuan respectively.The combined system has the smallest cost present value and the best economy.
