空调加热盘管防冻保护措施及要点

The Anti-freeze Protection Measures and Elements of Air-conditioning Heating Coil

针对严寒及寒冷地区的空调系统在运行过程中,经常出现的热水盘管冻裂问题及防冻保护对空调热风系统工作时产生的影响等问题,分析了问题产生的原因,并提出了在室外低温状态下的空调系统特殊运行方法的解决方式,并指出在设计过程中避免此种问题发生的设计要点。

This article points out the problems which the hot water heating coils often are f^ozen crack and the effect ofanti-freeze protection during the hot air system of air-conditioning operating in cold and fi＇eezing area. It analyses the reasons of these problems and raises solutions for the special operation technique of air-conditioning system in low-temperature state outside, and points out the design elements to avoid these problems in the design process.
