<p>In an air conditioner (1), a refrigerant circulation cycle is constituted by sequentially connecting a compressor (2), an indoor heat exchanger (4) having an indoor fan (4a), a PMV and an outdoor heat exchanger (6) having an outdoor fan (6a). An alternative refrigerant having a saturated pressure higher than that of HCFC22(R22) at the same temperature is used as a refrigerant. The blowout angle of air blown out from the indoor fan (4a) is vertically regulated by lateral louvers. An indoor controller, a louver motor (LM) and a louver drive circuit are adapted to control, at the start of heating operation, the lateral louvers (27a,27b) so as to direct the air flow upward toward a ceiling side in the room and, when the indoor heat exchanger (4) reaches a state capable of executing heat exchange operation, adapted to control the lateral louvers (27a,27b) so as to direct the air flow downward toward a floor side in the room.</p> |
