Question 201Refrigeration & AC - Assistant Engineer

The correct answer is D) sub cooled high-pressure liquid. In a refrigeration system, the refrigerant entering the receiver is in a sub-cooled high-pressure liquid state. After the refrigerant is compressed in the compressor, it becomes a high-pressure vapor. This high-pressure vapor then flows through the condenser, where it is cooled and condensed into a high-pressure liquid. The liquid refrigerant is then sub-cooled before entering the receiver, which is a storage tank for the liquid refrigerant. The other options are incorrect because: A) the refrigerant is not in a superheated state at this point, B) the refrigerant is not in a superheated vapor state, and C) the refrigerant is not in a sub-cooled low-pressure liquid state.
