PURPOSE:To quicken the start-up of an indoor unit, provided with two sets of constituting elements such as a cross flow fan, a heat exchanger, an air suction port, an air outlet port and the like, upon heating operation. CONSTITUTION:A louver unit 31, provided at the air outlet port 11 of a first unit 3, is divided laterally into three divisions. A part of outlet air from the air outlet port 11, which is guided to a central louver 31a, is sucked into the air suction port 9 of a second unit 5 while air, guided to left and right louvers 11b, 31c, is sucked into the air suction port 7 of a first unit 3, then, the air is heated in heat exchangers 21, 19 respectively and, thereafter, is sent out of the air outlet ports 13, 11. By this method, the temperature of outlet air is risen. |
