High Superheat - Ferguson HVAC

15/5/2017· Excessive or high superheat is an indiion of insufficient refrigerant in the evaporator coil for the heat load present. This could mean that not enough refrigerant is entering the coil or this could also indie an excessive amount of heat load on the evaporator coil.

Operating principles and symptoms:High suction and …

High suction and low discharge pressures This condition is usually due to a fault within the compressor, such as broken valve reeds or incorrect seating of the valve reeds. If the suction reeds are at fault, some of the discharged vapour will be forced back into the suction side of the compressor as the piston reaches the top of its stroke.

AC Hose

Suction Hoses (low side) attach from the compressor to the evaporator. Discharge (high side) attach from compressor to condenser. Liquid Lines attach condenser to evaporator. Manifold hoses are coinations of suction and discharges lines.

Diagnosing A Restricted Liquid Line Can Be Tricky

26/11/2002· Many service technicians often become confused when the liquid line becomes restricted in the refrigeration system. This is because the symptoms often look like an undercharge of refrigerant. This article covers a refrigeration system with a restricted liquid line after the receiver using R-134a as the refrigerant. The refrigeration system is a low temperature freezer with a receiver and a TXV.

25/1/2019· The condenser is connected to the compressor by the discharge or High (Pressure) Side line. The discharge line should be HOT to the touch. The condenser is like a radiator with the refrigerant flowing thru it and giving off heat to condense (gas to liquid) the refrigerant into a liquid.

Suction Pressure - Questions On Suction Pressure …

When you have low suction pressure and high head pressure that means the there is a restriction in the liquid line and that the evaporator is getting starved. Check to see if the unit has an expansion valve on the evaporator inlet.

R22 Operating Pressure? | Yahoo Answers

1/8/2011· I have measured the pressures on my R22 AC system. I get 63 psig suction and 252 psig high side. The air discharge temperature at the duct nearest to the evaporator is 62 degrees. What does that tell me about the operation of my system?

ac - What is the purpose of high pressure service port in …

Also, when the system is vacuumed from the high side only, the discharge valve in the compressor stays opened and the low side is vacuumed from there. The expansion valve has an equalizer line and the valve''s diaphragm is exposed to the low side pressure (which acts on the underside of the diaphragm) from this line.
