摘　　要：单元式风冷冷风空调机组普遍采用波纹翅片管冷凝器。对冷凝器进行设计的关键是确定制冷工质在铜管内的冷凝换热系数及空气在翅片侧的表面换热系数,同时也需要考虑空气流过冷凝器的压降,以便选择风机。采用数学模型及换热关联式计算相关参数,在此基础上对R134a单元式风冷冷风空调机组的冷凝器进行设计。Wavy fin heat exchangers are usually applied as condensers for unit air conditioning. Obtaining condensation heat transfer coefficient of refrigerants inside copper tubes and surface heat transfer coefficient of air flowing fin-tube bundle is the key to condenser design. Meanwhile, pressure drop of air flowing condensers must be considered in order to choose air fans. Uses mathematical models and heat transfer correlation to calculate these parameters. Then designs a wavy fin-tube condenser of unit air conditioning using R134a as refrigerant.
