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.

Installation Operation and Maintenance Manual

Installation Operation and Maintenance Manual

Magnitude chillers are equipped with one or two compressors operating in parallel with a single evaporator and single condenser. The chillers use refrigerant R-134a that operates at a positive pressure over the entire operation range, so no purge system is required. The controls are pre-wired, adjusted and tested.

May 22, 2012 I have a trane chiller model # CVHE500 that has a problem with surging after initial startup. When I switch over to this chiller, as soon as the vanes start opening the chiller starts surging very loudly. I look at the head pressure and it is at -0.1 psig. I assumed if there was air in the condenser it would be reflected in high head pressure while the machine is surging …
