摘要(Abstract):

霜对制冷装置的换热带来不利的影响。为了帮助系统设计人员正确地使用和理解设备制造厂家所提供的技术参数 ,选定冷量及系统中主要部件的规格 ,本文介绍了一些重要的参数 ,旨在使制冷装置高效地运行。
Frosting on refrigerating plant exerts a negative influence on heat transfer.It will lead to a decrease of heat transfer coefficient and an increase of flow resistance of air.The research on frosting and defrosting on heat exchangers reported are summarized.Some important parameters to help system designers to select and understand design parameters correctly are illustrated,which make plants run efficiently.
