Show answer and explanation Correct answer: (B) Evaporator
Explanation P is the indoor heat exchanger. In cooling mode it absorbs room heat while the refrigerant evaporates, so it is the evaporator, B. The outdoor heat exchanger rejects heat as a condenser; the compressor and expansion device occupy the other labelled circuit positions.
