Causes And Solutions Of High Pressure Failures Of Chillers

Causes And Solutions Of High Pressure Failures Of Chillers

Dec 09, 2019 Dec. 09, 2019. The high-pressure fault of the chiller means that the compressor exhaust pressure is too high, which causes the high-pressure protection relay to operate. The compressor discharge pressure reflects the condensing pressure. The normal value should be 1.4 ~ 1.8MPa, and the protection value setting is recommended not to exceed 2.0MPa.
