High Discharge Low Suction

High Discharge Low Suction - Basically, you're starving the evaporator. I arrive to find a loud compressor, 200 psi suction and 275 head. There are three main reasons why a reciprocating compressor will simultaneously have a low head pressure and a high suction. A cold suction line (low superheat) with low suction pressure is a symptom of low evaporator air. A liquid restriction would result. Blue ⇔ true suction low pressure; First thing that comes to mind is bad valves. I have tried adjusting the charge to raise the low side pressure, but in doing so would also raise the high side exponentially. Low suction and high head is usually due to a restriction in the liquid line. Red ⇔ high pressure (either refrigerant line) place an insulated temperature probe on.
