A pressure gauge reading of 26 psig (179 kPa)inside the evaporator of a system using R-134a means the evaporating temperature of the refrigerant is about

Question

Quizplus · Accepted Answer

The pressure-temperature relationship for refrigerants, including R-134a, allows us to determine the evaporating temperature at a given pressure. A pressure of 26 psig (179 kPa) for R-134a corresponds approximately to an evaporating temperature of 30°F (-1.1°C). This relationship can be found in refrigerant pressure-temperature charts or tables specific to R-134a.
