High Discharge Low Suction

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

Blue ⇔ true suction low pressure; If the unit has an. First thing that comes to mind is bad valves. Basically, you're starving the evaporator. A cold suction line (low superheat) with low suction pressure is a symptom of low evaporator air. I arrive to find a loud compressor, 200 psi suction and 275 head. I have tried adjusting the charge to raise the low side pressure, but in doing so would also raise the high side exponentially. There are three main reasons why a reciprocating compressor will simultaneously have a low head pressure and a high suction.

First Thing That Comes To Mind Is Bad Valves.

Blue ⇔ true suction low pressure; Basically, you're starving the evaporator. There are three main reasons why a reciprocating compressor will simultaneously have a low head pressure and a high suction. I arrive to find a loud compressor, 200 psi suction and 275 head.

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. A cold suction line (low superheat) with low suction pressure is a symptom of low evaporator air. If the unit has an. A liquid restriction would result.

I Have Tried Adjusting The Charge To Raise The Low Side Pressure, But In Doing So Would Also Raise The High Side Exponentially.
