摘要
对总热换热器的三种流道形式(穿孔型、狭缝型、压花打孔型)进行研究,研究表明,这三种不同流道的总热换热器在热交换率和空气压降等方面比表面光滑的普通总热换热器有不同程度的增加,通过改进流道形式来提高热回收通风系统的换热性能。
This paper studies three runner type of total heat exchange facility,bored,slit and coining hole.The result shows that the heat exchange ratio and air-pressure drop of these three heat-exchange facilities increased compared with common heat exchange facility with smooth surface.The heat exchange property of heat recovery ventilating system can be improved by improve runner form.
