Experimental Research on the Exhaust Heat Recovery System Based on Heat Pump

Research purposes: In order to solve the defect of exhaust heat recovery system at present,a exhaust air heat recovery system based on heat pump was proposed,and its system performance was tested in winter conditions. The result can provide a reference for practical engineering applications.Research conclusions:The performance of exhaust heat recovery system based on heat pump was tested in winter. The following results by experiments was obtained:(1) The recycled heat by exhaust heat recovery system based on heat pump is greater than by the conventional heat recovery system.(2) The efficiency of exhaust heat recovery system is more than 2. 6,which is effective and energy conservation.(3) It can fully recycle indoor heat,guarantee the supply air temperature in the special environment and improve heat recovery efficiency.(4)It will provide important reference for the applications of exhaust air heat recovery system based on heat pump in practical engineering.
