PROBLEM TO BE SOLVED: To positively reduce air-conditioning load in a room without causing energy loss by appropriately operating an air flow system. SOLUTION: This air flow system is provided with a heat insulating screen 4 liftably disposed in an indoor opening in a position spaced from a window opening, to form a sealed space 8a partitioned from a living room space 1, between an outdoor sash 3 and the heat insulating screen 4 in a totally closed state of being lowered into a lowermost position while forming a ventilating clearance 9 and an air flow passage 8 in a state of being held into a clearance forming position lifted by a predetermined amount from the lowermost position; a temperature sensor 10 disposed in the clearance between the outdoor sash 3 and the heat insulating screen 4; and an exhaust means 11 having a suction port 13a opened to the upper part of the clearance, a shutter 14 for opening/closing the suction port 13a, and an exhaust fan 15. The heat insulating screen 4, the shutter 14 and the exhaust fan 15 are operated on the basis of the detected temperature of the temperature sensor 10. COPYRIGHT: (C)2005,JPO&NCIPI
