PROBLEM TO BE SOLVED: To reduce noise during operation, without having to increase to the size of an indoor unit. SOLUTION: Dimensions of respective parts are determined, such that the relation 1.5L1 <=L2 <=3.5L1 is satisfied, between an interval L1 from an indoor heat exchanger 23a to the circumferential surface of a tangential fan 25 and an interval L2 from the boundary of the indoor heat exchanger 23a and an indoor heat exchanger 23b to the circumferential surface of the tangential fan 25. |
