摘　　要：以空气源热泵为辅助热源的太阳能集中热水系统,不仅节能效率高,而且能保证全天候连续热水供应,是近年来太阳能利用的发展方向之一。淮海工学院学生浴室采用了空气源热泵辅助太阳能热水系统,设计用水人数17 000人,日需热水量184 t。介绍了该热水系统的工作原理及设计计算,并对5种热水工程方案从初期投资和运行费用方面进行了详细的经济性分析,结果表明:以空气源热泵为辅助热源的热水方案较其他方案具有更好的经济、环保效益。The high energy-efficient solar energy water heating system in conjunction with air source heat pump, supplying all-weather continuous hot water, is one of the developing direction of solar energy utilization in recent years. Students＇ Bathroom of Huaihai Institute of Technology use solar water heating system assisted with air source heat pump for 17000 students, requiring 184 tons of hot water every day. The working prineiple and design calculation of hot water system are expounded with detailed analysis of the initial investment and operating costs for five kinds of heating water engineering solutions. Results show that air source heat pump as auxiliary heat source has better economic and environmental benefits.
