PROBLEM TO BE SOLVED: To provide an air conditioner that enables appropriate selection of a first dehumidification heating mode and a second dehumidification heating mode.SOLUTION: An indoor evaporator 20, heating means 34 and an indoor condenser 12 are disposed in this order in a flowing direction of air sent to an air-conditioning target space. The control means 40 controls operations of refrigerant flow switching means 17, 23, 50 such that a mode is switched to a first dehumidification heating mode when a target blowout temperature TAO is lower than a threshold value α and the mode is switched to a second dehumidification heating mode when the target blowout temperature TAO is higher than the threshold value α, and as a suction air temperature TCIN of the indoor condenser 12, a suction air temperature TIN of the indoor evaporator 20 and an outside air temperature TAM increase, the threshold value α is increased.SELECTED DRAWING: Figure 2 |
