Question 55Refrigeration & AC - Assistant Engineer

The correct answer is D) saturated refrigerant temperature. Most compound and standard pressure gauges used for refrigeration service are provided with a scale indicating the saturated refrigerant temperature. This is because the pressure of a refrigerant in a closed system is directly related to its saturation temperature. By referencing the pressure reading on the gauge, the technician can determine the corresponding saturation temperature of the refrigerant, which is a critical parameter for monitoring and troubleshooting the refrigeration system. The other options are incorrect because they do not directly correspond to the information provided by a standard pressure gauge. Superheated and subcooled refrigerant temperatures, as well as absolute pressure, are not directly indicated on these types of gauges used for refrigeration service.
