Abstract

PURPOSE: To effectively utilize cooling air by stopping a cooling mechanism such as a fan, when air flow rate detecting means detects a large air flow rate.
CONSTITUTION: In the case of an underfloor air conditioning in which pressurized cooling air is fed from an underfloor 6, opening/closing means 13 is opened by the pressure of the air, and the air is fed into a device 5 through passages 10, 11. In this case, a skirt is mounted around a lower part of the device 5 to block a gap to a floor surface 19, thereby preventing leakage of the air. On the other hand, in the case of air conditioning in the room by lowering a temperature in the room, since the cooling air does not have a pressure, the means is closed, and the air is sucked by a fan 14 through the passage 11. When air flow rate detecting means 15 detects a large air flow rate, the fan 14 is stopped. Thus, the air can be effectively utilized.
