Answer

B. The coil that is connected to the permanent suction Explanation 1. Identify the Function of an Evaporator In a heating or cooling system, the evaporator is the coil where the refrigerant absorbs heat and evaporates. It is typically connected to the suction side of the compressor. 2. Analyze Each Option A. The coil connected to the uncovered port - This does not determine the evaporator. B. The coil that is connected to the permanent suction - This is correct as the evaporator is on the suction side. C. The coil that has its port covered by the sliding valve - This does not determine the evaporator. D. The indoor coil that is always connected - This is not specific enough to determine the evaporator.
