Question 65Refrigeration & AC - QMED

The correct answer is A) the saturation temperature of the refrigerant that corresponds to the gauge pressure at the point of measurement. On a compound gauge for a refrigerant system, in addition to the indicated gauge pressure, the saturation temperature corresponding to that pressure is also displayed. This is because the saturation temperature is a critical piece of information needed to understand the state and behavior of the refrigerant in the system. The other options are incorrect because they do not represent the complete information provided on a compound gauge. Option B is incorrect as the gauge does not display metric pressure equivalents. Option C is incorrect as the gauge displays gauge pressure, not absolute pressure. Option D is incorrect as the gauge displays the saturation temperature, not the actual temperature of the refrigerant.
