摘　　要：表冷器在空调工程中的应用十分广泛.通过控制变量法来分析流体以叉流形式流动的表冷器的效能,结果表明表冷器效能随水流速的增大而增大,随迎面风速和析湿系数的增大而减小.为表冷器设计者在综合考虑这些因素而进行设计时提供数据参考,全面提高表冷器效能,达到节能降耗的目的.Surface air coolers are widely used in air conditioning engineering. The control variable method was used to analyze the efficiency of surface air coolers whose fluid flows in the form of cross flow. The results show that surface air cooler efficiency increases with the increasing of flow velocity, and decreases with the increasing of wind speed against the face and the damp coefficient. It provides reference data for surface air cooler designer in comprehensive considering of these factors when designing, increases the efficiency of the surface air cooler, and achieves the goal of saving energy consumption.
