Dear all, We are operating Packaged HVAC system of 60 Tons.
We are facing the problem of compressor suction falling suddenly & compressor trips due to low suction pressure. We suspect that the NRV in the outlet of Air cooled condenser is the cause.
Refer the attached SLD. If we start the compressor A, then condenser-A will start automatically. the NRV (Red) in the outlet of the condensor-B passes the gas sometimes, so the R-22 gas enter the standby condensor-B, causing the Pr. drop in the system.
Kindly help us to get rid off this problem.
