济南地区热泵式热回收系统节能分析

Energy saving analysis of heat pump heat recovery systems in Jinan

建筑热回收技术是降低建筑能耗的重要途径,文章探讨了热回收系统的常见类型;阐述了热泵式热回收系统的应用原理;提出了热回收系统的评价方法;通过与普通显然热回收系统的分析比较,探索了济南地区气候条件下热泵式热回收系统的节能潜力。结果表明:对于排风量较大的中央空调系统,采用普通热回收装置与热泵式热回收系统联合运行模式,冬季热回收系统的效率可达到3.18。

Heat recovery technology in building is an important way of reducing energy consumption and this article probes into the common types of heat recovery system. It describes the application principle of heat pump heat recovery system, gives the evaluation method of heat recovery system and by comparing it with common sensible heat recovery system, explores the energy saving potential of heat pump heat recovery system in Jinan climate conditions. The results show that heat recovery sys- tem efficiency can reach 3.18 when the common heat recovery device and heat pump heat recovery system are used jointly in winter in the central air conditioning system of large exhaust air.
