Hypothermia
Subcooling is the difference between the condensing temperature and the temperature of the refrigerant leaving the air conditioner condenser. Subcooling increases the amount of liquid refrigerant in the air conditioner circuit.
Overheat
Superheat is the difference between the temperature of the refrigerant at the outlet of the cooler and the evaporation temperature.
Overheating converts a large amount of refrigerant into a gaseous state in the refrigeration circuit.
Supply air temperature
The temperature of the incoming air must be between 2°C and 10°C.
Note. In all cases, measure the superheat temperature and the supply air temperature.
