RefrigerationPregunta 58 de 110
A technician measures a suction pressure whose saturation temperature is 40 F and a suction line temperature of 52 F. What is the superheat?
a.4 degrees
b.8 degrees
c.12 degrees
d.20 degrees
Explicación
Superheat equals the suction line temperature minus the saturation temperature: 52 F minus 40 F equals 12 degrees. This value helps confirm proper evaporator feeding and charge. Very low superheat risks liquid floodback, while very high superheat suggests underfeeding.
