摘　　要：在结构特性一定且风量不变的情况下,室内机中表面式换热器的通用热交换效率与进风参数无关,利用厂家实测值对其进行了验证。为多联机室内机在变配电房内干工况运行时的制冷量计算提供了方便,有利于多联机系统合理选型。With the certain structural characteristics and constant air volume,the general heat exchange efficiency of the surface heat exchanger in the indoor unit has nothing to do with the air inlet parameters,and the measured value of the manufacturer is used to verify the performance in this paper.When the VRF operating in dry condition for the transformer substation,the related analysis makes the calculation of cooling capacity easier,which is beneficial the reasonable selection of the system.

关 键 词：通用热交换效率 多联机室内机 干工况 制冷量
