摘　　要：针对现有中央空调预热盘管防冻方法的弊端,通过预热盘管入口温度与预热盘管后侧温度同时监测,以及区分机组运行状态和机组停机状态下预热盘管调节阀开度的不同控制方法,彻底解决中央空调机组预热盘管冬天冻裂问题。In view of the disadvantages of the existing anti freezing methods for the preheating coil of central air conditioning,through the simultaneous monitoring of the inlet temperature of the preheating coil and the rear temperature of the preheating coil,as well as the different control methods to distinguish the opening of the regulating valve of the preheating coil under the operation state and the shutdown state of the unit,the problem of winter frost crack of the preheating coil of central air conditioning unit can be solved thoroughly.

关 键 词：预热盘管入口温度 预热盘管后侧温度 预热盘管调节阀
