摘要： PURPOSE:To reduce noise due to a blower and also to increase a blowing efficiency by combining the main body of air conditioner with a blowing device. CONSTITUTION:A heat exchanger 8 is provided in an air conditioner 3. An intake port 6 for introducing air is provided on one side of the heat exchanger 8, and during an ordinary operation by a fan motor 2 and a propeller fan 7, the air is sent to the upper part of the air conditioner 3 from an intake port 6. In order to increase a blowing effect, the air conditioner is made to have a structure making it possible to use it in combination with a blowing device 4. The blowing device 4 has a structure provided with the fan motor 2, the propeller fan 7 and straightening plates 1. Besides, the blowing device 4 can operate in gearing with the motion of the air conditioner 3. The number of the straightening plates 1 is different from that of vanes of the propeller fan 7 and it is possible to suppress a swirl generated in a stream of air at the time of blowing and to straighten the stream by the straightening plates 1. Accordingly, the blowing device of which the noise is suppressed efficiently is obtained. Besides, the air conditioner can be made small in size and a long duct can be used for a draft duct 5.
