压缩机运行出现结霜现象、运行压力偏低导致报警A、 冷冻水系统故障。 1

Compressor operation appears frosting, resulting from low operating pressure alarm <br>A, chilled water system failure. <br>1) Is there an air (exhaust air) within the examination chilled water system. <br>Whether 2) Check the chilled water system water and makeup water of normal (control supplement water tank <br>level).

The compressor operation frosting phenomenon, low operating pressure leads to alarm<br>A, the frozen water system failure.<br> 1) Check the frozen water system for air (discharge air).<br> 2) Check the amount of water in the frozen water system and the replenishment water is normal (control the water tank<br> water level).

The alarm is caused by frosting and low operating pressure during compressor operation<br>A. failure of chilled water system.<br>1) check whether there is air (exhaust air) in the chilled water system.<br>2) check whether the water volume and make-up water of the chilled water system are normal (control the make-up water tank)<br>Water level).<br>
