The liquid line temperature is 88°F. Subtracting the two numbers gives 36°F. High superheat and high subcooling indicates a problem with the metering device.

Subcooling is when the liquid refrigerant in your is colder than the minimum temperature required to keep it from boiling. This can happen when the system is first turned on, or if there’s a problem with the system. When this happens, the liquid refrigerant can change from a liquid to a gas phase, which can cause problems with the HVAC system.Using Superheat and Sub-cooling THE REFRIGERATION CYCLE Based on the principle that heat flows naturally from warmer areas to cooler areas, the refrigeration cycle consists of seven stages: 1. Compression of hot gas 2. Cooling 3. Condensing 4. Subcooling 5. Expansion 6. Evaporation 7. Super heating A basic vapor compression refrigeration systemSuperheat and subcooling are the two fundamental concepts in any HVAC system.

SUPERHEAT Superheat is the amount of heat added to a dry vapor, in the absence of liquid, to raise the vapor temperature above its boiling point (saturation point) corresponding to the pressure at which it is operating. If there is liquid refrigerant present, there can be no superheat. 33748 It's simply shedding heat energy, moving left all the way through the saturation dome, and even subcooling the refrigerant slightly at the end. Point 3 : The "throttle" is the metering device that separates the high-pressure condenser from the low-pressure evaporator -- usually a thin capillary tube in household refrigerators. ots carried Subtract the two numbers to get the subcooling. For example, 275 psi head pressure on an R-22 system converts to 124°F. The liquid line temperature is 88°F. Subtracting the two numbers gives 36°F. High superheat and high subcooling indicates a problem with the metering device. Subcooling is measured at the high side liquid line. In most basic terms, subcooling measures by how many degrees a liquid refrigerant is cooled below the saturation temperature. All of this subcooling is happening in the 2nd part of the condenser coils (outdoor unit). You can read all about subcooling and superheat here. How to measure SUPERHEAT and SUBCOOLING!
