摘　　要：基于公共浴室热水生产设备节能减排改造的需要,本文设计了可回收洗浴废水余热的空气源/污水源复合热泵热水系统,在合肥工业大学屯溪路校区建立了应用示范工程,进行了运行测试和应用研究工作。结果显示:在8℃±1.2℃的环境温度、50℃供水设定温度的运行条件下,通过预热器和污水源热泵机组进行余热回收,洗浴废水温度从30.6℃降低至15.5℃,热回收的能量约占热水生产总能量的1/3;在10℃±1℃的环境温度、45℃供水设定温度的条件下,复合热泵系统的能效比为3.45,与单独运行空气源热泵的2.96相比,能效提高16%;与传统的燃气锅炉设备、电热水器对比分析,复合热泵系统可分别节约运行费用53.3%、72.4%,节能、环保和降费的优势明显。In order to achieve energy conservation and emissions reductions, an air source/sewage source heat pump hot water system was designed. Field tests were conducted in a demonstration project on Tunxi Road at Hefei University of Technology. The results show that at an ambient temperature of 8 ℃ -1.2 ℃ and a water supply temperature of 50 ℃ condition, the wastewater temperature is decreased from 30. 6℃ to 15.5℃ through preheater and waste heat recovery. Heat recovery energy accounts for about 1/3 of the total energy for hot water heating. At an ambient temperature of 10 ℃- 1 ℃ and a water supply temperature of 45 ℃ condition, the energy efficiency of the composite heat pump system was 3.45. Compared with a separate air source heat pump, the energy efficiency is increased by 18%. Compared with a gas water heater and an electric water heater, the composite heat pump system can reduce operating costs by 53.3 % and 72.4%, respectively. The results show obvious advantages of composite heat pump system on energy saving, environmental protection, and cost reduction.
