Abstract: PURPOSE:To improve the comfort and efficiency of heating by an air conditioner which includes an indoor unit with an indoor heat exchanger and a heat conveying device that circulates refrigerant. CONSTITUTION:An air conditioner includes an indoor unit equipped with an indoor heat exchanger 19 and a cross-flow fan 15 and a heat conveying device that circulates a refrigerant. The indoor heat exchanger 19 consists of two sections arranged vertically or in a doglegged form. A group of heat transfer tubes 18 is connected and formed into a refrigerant path so that the upper section above the bend 20 of the doglegged form is at high-temperature and the lower one below the bend 20 is at low-temperature. Therefore, among air sucked into the heat exchanger 19, a portion passing through the upper section is heated to high temperatures, makes a U-turn and is blown out from below by the cross-flow fan 15. The other portion passing through the lower section makes a U-turn and is blown out from above as it remains at rather low temperatures. Therefore, the low temperature air blown from above restrains the high-temperature air blown from below from flowing up, so that the hot-air can reaches to a distance.
