Abstract
When a fully-closable expansion valve is used, there is a possibility that the expansion valve is fully closed thereby to block a refrigerant circuit. In an air conditionerof the present invention, an indoor heat exchangerincludes an auxiliary heat exchangerand a main heat exchangerdisposed leeward from the auxiliary heat exchanger. In an operation in a predetermined dehumidification operation mode, a liquid refrigerant supplied to the auxiliary heat exchangerall evaporates midway in the auxiliary heat exchanger, i.e., before reaching the outlet. Therefore, only an upstream partial area in the auxiliary heat exchangeris an evaporation region, while an area downstream of the evaporation region in the auxiliary heat exchangeris a superheat region. Further, an evaporation temperature sensorwhich detects an evaporation temperature is disposed downstream of an expansion valvein an outdoor unit
