RefrigerationCâu 57 / 110
Superheat is defined as the temperature of the refrigerant vapor above what?
a.Its condensing temperature
b.Its saturation (boiling) temperature at the existing pressure
c.The outdoor ambient temperature
d.The compressor discharge temperature
Giải thích
Superheat is the number of degrees the refrigerant vapor has been heated above its saturation temperature for the measured pressure. Adequate superheat ensures only vapor, not liquid, returns to the compressor. Technicians measure it to evaluate evaporator charge and load.
