摘要
在空气和霜层之间为过饱和空气假设的基础上,针对平肋肋片管式换热器的结霜过程,建立了数学模型,考虑了霜层密度变化和霜层阻力引起空气流量减小等因素,并将结霜模型与换热器传热特性模型有机地结合起来。
Based on the assument that the water vapor is supersaturated at the interface between the air steam and frost layer, eastablish a mathematic model for the frost accumulation on the firmed tuble heat exchanger, taking into account the variation of frost density and the decrease of air steam rate caused by frost density. Contact the heat transfer characterist model of heat exchanger with frosting model for the improved studty.
