Technician A says the suction line connected to the compressor should be cool to the touch. Technician B says the discharge line from the compressor to the condenser should be hot along its entire length. Who is correct?

Question

Quizplus · Accepted Answer

Technician A is correct because the suction line, which carries low-pressure refrigerant to the compressor, should indeed be cool as it reflects the refrigerant's state before compression. Technician B is correct because the discharge line, which carries high-pressure, high-temperature refrigerant from the compressor to the condenser, should be hot, indicating the refrigerant is in a high-energy state post-compression.
