<P>PROBLEM TO BE SOLVED: To provide a simplified air conditioning system utilizing air in an air-conditioned room for simply air-conditioning another room. <P>SOLUTION: The simplified air conditioning system allows air in a first room R air-conditioned by air conditioning sources C1, C2 to be introduced into a second room T not air-conditioned to air-condition the second room. The simplified air conditioning system comprises an air passage 1 communicating the first room R with the second room T, a blowing device 12 having a blowing fan 2 for blowing air in the first room R via the air passage 1 to the second room T, and a backflow preventing means 3 for preventing the backflow of air from the second room T to the first room R. The backflow preventing means 3 opens the air passage 1 during operation of the blowing fan 2 and closes the air passage 1 during non-operation. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
