介绍了不同的废气余热回收装置的特点，并以实际工程为例，介绍了转轮换热器、板翅式换热器和回收式新风热泵机组三种回收式废气余热回收系统，分析了这三种回收式余热回收系统的节能经济性，并对系统的初期投资和回收期进行了估算，认为回收式新风热泵机组具有较大的节能潜力。
Characteristics of different heat recovery devices from exhaust air were introduced.An actual project was taken as an example,three heat recovery systems from exhaust air by rotary wheel exchanger,plate- fin heat exchanger and recovery fresh air heat pump units were presented.The energy saving and economic of these heat recovery systems were analyzed.Initial investment and payback period of the system was reckoned.Considering the above situation,the recovery fresh air heat pump unit has a considerable energy saving potential.
