PROBLEM TO BE SOLVED: To provide dehumidification operation which is close to a genuine reheating whole degradation of heating efficiency is suppressed. SOLUTION: An indoor heat exchanger comprises heat exchangers 22 and 23 which, provided windward, act as an evaporator at dehumidification operation, a heat exchanger 24 which, and provided leeward of the heat exchanger 23, acts as a reheater at dehumidification operation, and a heat exchanger 21 which, provided adjoining the heat exchanger 22, acts as a reheater at dehumidification operation. Since, a worm air from the heat exchanger 21 at high temperature, a chilled air from the heat exchanger 22 at low temperature, and an air from the heat exchanger 24 at near room temperature are sucked, in layer in a fan 33, 3 kinds of air is efficiently mixed, for dehumidification operation close to a genuine reheating while degradation of heating efficiency suppressed. |
