摘　　要：针对冀南地区某高校公共浴室洗浴热水问题,采用太阳能+污水源热泵复合热水系统,以燃气锅炉为辅助热源,该系统具有高效、稳定、清洁、经济等优势。通过测试该新建洗浴热水系统在4种不同工况下的水温、水流量以及耗电量,计算得到了太阳能集热量、热效率以及污水源热泵系统的实际热回收量、能效比(COP)。结果表明:在4种不同辐射量区间内太阳能的贡献率分别为100%、49.96%、39.82%、0%;污水源热泵机组的COP维持在5~6之间,系统COP维持在4~5之间,余热回收效率高。此外,太阳能+污水源热泵系统相比燃气锅炉运行费用节省了5.3万元。因此太阳能+污水源热泵复合系统运行效果好且运行费用低。Aiming at the hot water supply problem of a public bathroom in an university in southern Hebei province,a composite hot water system with solar energy and a sewage source heat pump was adopted,and a gas⁃fired boiler was used as the auxiliary heat source.This system features a highly efficient,stable,clean,and economical performance.By testing the water temperature,flow rate and power consumption of the new bath hot water system under four different working conditions,the actual heat recovery amount and energy efficiency ratio(COP)of the solar heat collection,thermal efficiency,and sewage source heat pump system were calculated.The results show that the contribution rate of solar energy is 100%,49.96%,39.82%,and 0%respectively in four different radiation ranges.The COP of the sewage source heat pump unit is maintained between 5~6 and the COP of the system is maintained between 4~5,with high waste heat recovery efficiency.In addition,the operating cost of the solar+sewage source heat pump system is 53,000 Yuan less than that of the gas⁃fired boiler.Therefore,the solar energy+sewage source heat pump system has a sound operation effect and low cost.
