PURPOSE:To prevent the air flow amount from lowering by a method wherein, simultaneous with the operation of outdoor unit of the present machine, outdoor blowers are also operated in parallel while the outdoor blowers perform operations whose revolutions are reverse to each other, air flow directions of each blowers are made in the manner that interference in air flow of each blowers are minimized to the possible extent. CONSTITUTION:In front of a main casing 1, a plurality of air guiders 6-1, 6-2, and 6-3 for smoothing blown out air flows are arranged in cascade fashion, while a plurality of propeller type blowers 7-1, 7-2, and 7-3 for outdoor use are provided at respective positions relatively to the air guiders 6-1, 6-2 and 6-3, whose fixing directions of vanes and revolution directions thereof are different to each other. In the same manner as outdoor blower 7-1, revolution direction of the outside blower 7-3 is set clockwise as viewed from its front, however, on the contrary, the blower 7-2 is changed in its vane pitch, i.e. it revolves counterclockwise. Between outdoor blowers 7-1 and 7-2; outdoor blowers 7-2 and 7-3 respectively, blown out air flows are so designed that the two blow out airs moderate the respective air flows with each other, thereby lowering the blown out air amount mutually, while alleviating another's blow out interference in blowing strength. |
