Energy saving analysis of heat pump heat recovery systems in Jinan

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 system 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.
