Hvac superheat verses subcooling


superheat is the difference of line temperture at suction of the compressor to the pressure converted to temperture for freon used in system. subcooling is the difference of temperture measured on liquid line compared to pressure measured at discharge line converted to temperture for the freon used in system.

When technicians take an air conditioning course, one of the first things they learn is to use superheat to charge a fixed orifice air conditioning system.

Superheat is not hard to deal with, but the technician needs to take four good measurements.

To get the actual superheat, the technician measures suction line pressure and suction line temperature. When he reads suction line pressure, he reads the *F scale on his gauge. That's the boiling point of that refrigerant at that pressure. To get actual superheat, subtract the suction line boiling point temperature from the measured temperature of the suction line.

To read get the required superheat from the most common A/C manufacturer's superheat charts, the technician measures indoor "wet bulb" temperature and outdoor air temperature ("dry bulb"). Using these two temperatures the technician can look up the required superheat on most A/C manufacturers' superheat charts. Required superheat's can vary from 5 *F to over 45*F depending on the conditions (indoor wet bulb and out door dry bulb). The higher the load, the higher the required superheat.
The technician adds or subtracts refrigerant to decrease or increase the actual superheat to match the required superheat.

Superheat is the temperature difference between the boiling point of the refrigerant in the evaporator and the actual temperature of the refrigerant gas after the evaporator. It is the "extra" temperature (or temperature rise) the refrigerant picks up in the evaporator after it boils.

When charging the system, the technician adds as much refrigerant as he can. But if he adds too much (overcharge), he risks flooding the compressor with liquid refrigerant.

The biggest risk of flooding is under low load conditions: low outside temperatures and low indoor wet bulb temperatures. The refrigerant boils off late in the evaporator. To make sure the refrigerant is all boiled off before the end of the evaporator, the the A/C manufacturer's required superheat chart directs the technician to stop adding refrigerant when the suction line temperature gets down to within a few degrees of the boiling point inside the evaporator. The "few degrees" is the superheat. At low load conditions, the superheat is often specified as five or six degrees. It's a safety factor to make sure no liquid gets to the compressor.

At other load conditions, as determined by outdoor air and indoor wet bulb temperatures, the required superheat is given by a the superheat chart supplied by the A/C manufacturer. The higher the temperatures, the higher the load and the higher the required superheat.

Doing a superheat analysis is the best way to insure that an air conditioner has the proper charge.
