Question 54Refrigeration/AC - Assistant Engineer70% to pass
If the valve labeled "D" in the illustration is a suction service valve, what will the port labeled "7" be connected to? Illustration GS-RA-08
AI Explanation
The correct answer is C) to the line connected to the evaporator outlet.
In a refrigeration system, the suction service valve labeled "D" is typically connected to the outlet of the evaporator. This allows the suction line, which is the line connected to port "7", to draw refrigerant vapor from the evaporator after it has absorbed heat and undergone a phase change. This suction line then carries the refrigerant vapor back to the compressor inlet.
The other answer choices are incorrect because they do not align with the typical refrigeration system layout. Option A would connect the suction line to the wrong side of the compressor, while options B and D would not properly draw refrigerant vapor from the evaporator outlet.
