Exhaust air sensible heat recovery equipments include Plate Sensible Heat Exchangers, Heat Pipe Exchangers; Exhaust air total heat (enthalpy ) recovery equipments consist of Plate-fin Type total Heat Exchangers, Rotary Heat Exchangers, Heat Pump Heat Exchangers, Rotating Channel Heat Recovery Devices, Solution Enthalpy Recovery Devices. And Plate Sensible Heat Exchangers are comprised of Plate Type Sensible Heat Exchangers and Plate-fin Type Sensible Heat Exchangers; Heat Pipe Exchangers involve Gravity Heat Pipe Type Heat Exchangers, Gravity Heat Pipe Waste Heat Recovery System, Sperated-type Thermo-siphon Heat Exchangers. Moreover, in this paper Pulsating Heat Pipe with potential application in HVAC systerm is introduced briefly. This paper makes a simple analysis and comparison in terms of operational principle and pros and cons of every heat recovery devices involved. Based on what is shown above, by combining project example existing in some papers, this paper emphasises
