PURPOSE: To prevent a dripping of water from being carried out on a cross-flow fan by a method wherein the number of rows of heat exchanging tubes of an indoor heat exchanger is set such that the number of rows of heat exchanging tubes in a heat exchanger installed at an upper side is made to be lower than the number of heat exchanging tubes of a heat exchanger placed at the most near lower side of a cross-flow fan. CONSTITUTION: A first indoor heat exchanger 4 is placed at a lower side near a cross- flow fan 2, and a second indoor heat exchanger 7 is placed at an upper side which is a far position from a cross-flow fan 2. The number of rows of heat exchanging tubes 7a of the second indoor heat exchanger 7 is set to be lower than the number of rows of heat exchanging tubes 4a of the first indoor heat exchanger 4. Drain condensed by the first indoor heat exchanger 4 is positively received by a first drain pan 3, drain condensed in the second indoor heat exchanger 7 is reduced in correspondence with the less number of rows of the heat exchanging tubes 7a of the second indoor heat exchanger 7 in view of its volume, the volume does not reach such an amount of overflowed drip against its flowing-down action, but the flow is positively flowed down onto the first indoor heat exchanger 4, and the flow is flowed down into the first drain pan 3. |
