北方地区某新风能量回收系统用户风机盘管冻裂原因分析
Cause analysis for fan-coil frosting cracking in a fresh air energy recovery system user in northern residence
摘要：
分析了该住户风机盘管在供暖初期冻裂的原因——空气空气能量回收系统新风送风温度低于0 ℃，指出为防止送风温度过低导致盘管冻裂，应避免在住宅供暖设计中采用将新风直接送入热水盘管再热的方式。

Abstract：
Analyses the reason for fan-coil cracking in the early heating period when the fresh air supply temperature of ERV system is lower than 0 ℃, and points out that in order to prevent fan-coil frosting cracking caused by the low supply air temperature, reheating fresh air by the hot water coil in residential building heating design should be avoided to adopt.
