Question 58Refrigeration & AC - Assistant Engineer
70% to passIn addition to the indicated gauge pressure, what other information is presented on the compound gauge for the hypothetical refrigerant illustrated? Illustration GS-RA-16
Athe actual temperature of the refrigerant at the point of measurement
Bthe saturation temperature of the refrigerant that corresponds to the gauge pressure at the point of measurement
Cthe absolute pressure of the refrigerant at the point of measurement
Dthe metric pressure equivalent of the refrigerant at the point of measurement
AI Explanation
The correct answer is B) the saturation temperature of the refrigerant that corresponds to the gauge pressure at the point of measurement. This is because a compound gauge for a refrigeration system typically displays both the gauge pressure and the corresponding saturation temperature of the refrigerant at that pressure. The saturation temperature is the temperature at which the refrigerant would begin to condense or boil, based on the pressure measured. This information is critical for technicians to diagnose the refrigeration system's performance. The other options are incorrect because they do not represent the full information conveyed by a compound gauge in a refrigeration system.
