When taking readings at the suction service valve of an operating refrigeration compressor to determine pressure and temperature, what statement is true?

Question

Accepted Answer

The pressure is directly read on the compound gauge pressure scale and the temperature is directly read on a separate thermometer temperature scale as the refrigerant is superheated at this point.

Answer

The pressure is directly read on the compound gauge pressure scale and the temperature is directly read on the compound gauge saturation temperature scale as the refrigerant is saturated at this point.

Answer

The pressure is directly read on the compound gauge pressure scale and the temperature is directly read on a separate thermometer temperature scale as the refrigerant is sub cooled at this point.

Answer

The pressure is directly read on the compound gauge pressure scale and the temperature is directly read on the compound gauge saturation temperature scale as the refrigerant is superheated at this point.
