WebAug 19, 2024 · If superheat is high and sub-cooling is high: Could have blockage in coil, orifice or line set. If superheat is low and sub-cooling is low: Orifice could be too big, there is no orifice in the unit of the orifice is stuck and refrigerant is by-passing it. Superheat is telling you what is going on in the evaporator. WebHigh superheat= not enough refrigerant in the evaporator. Low subcool= not enough refrigerant in the condenser . Compression ratio is fine, unlikely to be the valves. ... This would cause the low pressure/temperature of the discharge and SCT which gives us the no subcooling. Also causes the liquid line pressure to be low which will either cause ...

WebJan 22, 2024 · High superheat low subcooling on a TXV system means that there is no sufficient amount of refrigerant in the evaporator and there is low amount of the refrigerant in the condenser unit. This condition is mainly caused by low charge in an air conditioning system and can be fixed by sealing leaks and adequately charging the system with a … WebHow to Check Subcooling. Attach the thermometer to the liquid line. This time, near the condenser. Then take the head pressure in Psi and convert it to the temperature on the pressure/temperature chart. Assuming you are dealing with a R22 system, let’s say the head pressure is 260Psi. This will convert to 120F. can i use pc controller on ps3
