Question 96Refrigeration & AC - 1st Asst/Chief

The correct answer is B) to the line connected to the evaporator outlet. The reasoning is that if valve "D" is a suction service valve, it would be connected to the suction side of the refrigeration system, which is the line from the evaporator outlet. This allows the suction service valve to access the low-pressure refrigerant vapor exiting the evaporator before it enters the compressor. The other options are incorrect because: A) The compressor inlet would be on the suction side, not the outlet. C) The evaporator inlet would be on the high-pressure side, not the suction side. D) The compressor outlet would be on the high-pressure side, not the suction side.
