Mar 9, 2020 · This small amount of heat to reject will cause a low condensing pressure and temperature. Most of the refrigerant will then be stored in the condenser and receiver, simulating a pumped-down refrigeration system. Symptoms of a liquid line restriction include: Low evaporator (suction) pressure; High superheats; Head pressure: 400 lbs. Condenser air in: 140º F. I guess Condenser air out: what; about 160º F. I am guessing? LSC is: 30º F. - so the system has plenty of refrigerant in it Suction Pressure: 105 lbs. Suction Line Temp: 65º F. SSH: 30º - so the evaporator does not have enough refrigerant in it. What am I missing? PHM-----Low suction pressure high head pressure is a common issue that can occur in an air conditioning (AC) system. This condition is characterized by a decreased refrigerant pressure in the system, known as suction pressure, and an increased output pressure in the compressor, known as head pressure.High Head Pressure. High head pressure is typically accompanied by a low suction pressure. This combination can be indicative of restricted refrigerant. Essentially, this means that air and vaporized water travel through your HVAC’s evaporator until they get to the top of the compressor, where it remains because it will not condense.Both fans working fine. Good air flow through evaporator and condenser. There are no leaks, and no icing. I have tried adjusting the charge to raise the low side pressure, but in doing so would also raise the high side exponentially. (i.e. Increase the suction pressure by 20 psi, and the head pressure would jump as much as 150 psi)Low suction pressure and high head pressure is a condition where there is a decreased refrigerant pressure in the AC system and at the same time a high output pressure in a compressor. This condition is mainly caused by a defective or malfunctioning TXV valve. See moreAnd, just as common, is suction pressure and/or head pressure being involved in the cause. Often, the refrigeration system will still run, but it’ll run inefficiently because the suction pressure is too high while the head pressure is simultaneously too low. ... Compressor amperes: low.

problems. Fluid flows from areas of high pressure to areas of low pressure. Pumps operate by creating low pressure at the inlet which allows the liquid to be pushed into the pump by atmospheric or head pressure (pressure due to the liquid’s surface being above the centerline of the pump). Consider placing a pump at the top of the mercuryConnecting the low pressure side to the suction side of the compressor helps in sucking out the excess pressure from low side AC. c. Close the Service Valve Before Releasing Pressure. You can use a hex key or a wrench to close the service valve on the high-pressure side but don’t close it entirely. d.Attach a drum of proper, clean refrigerant to the center port of the charging manifold with one of the charging hoses. Attach a second charging hose to the suction gauge (low pressure) side of the gauge manifold. Remove the cap from the suction line valve. Loosely attach the suction gauge hose to the line valve.The TXV also needs a proper pressure drop (about 100 PSI); without that pressure drop, the TXV can’t do its job properly. When the suction pressure is low, the technician should take the subcooling and superheat inside and outside.
