PURPOSE:To improve drastically the dehumidifying capability by a method wherein at the time of dehymidifying operation, the drain water which is generated at a heat-exchanger to provide the reaction of an evaporator is assuredly prevented from flowing in a heat-exchanger to provide the reaction of a reheater, and the reheating efficiency of the heat-exchanger is completely ensured. CONSTITUTION:A first indoor side heat-exchanger 8 and a second indoor side heat-exchanger 9 are bent into an L-shape, and are integrally constituted into a heat-exchanger main body 7 which consists of a large number of fins 16 of which the upper sides are tilted, heat-exchanging pipes 17 which are penetrated in the fins while being arranged by plural lines in the longitudinal direction, and slits 18 which are provided serially between respective lines of the heat- exchanging pipes 17 with a specified interval and divide the fins 16 and heat- exchanging pipes 17 in the longitudinal direction. Then, a tilt angle which is the tilt angle beta of the fin 16 or higher is given to joints 19 which are confronted end parts of the slit 18. |
