Title: Blowing method for purified air in clean room
Inventor: MIYAKOSHI TAKASHI
IPC: F24F7/06
Filed: 1988-05-02
Abstract: PURPOSE:To prevent the ascending air current of purified air, which is caused in a clean room, and to maintain high cleanliness by forming a cold air layer within a underfloor chamber. CONSTITUTION:Air in a ceiling chamber 12 is sucked into each of suction boxes 14 and passes through HEPA (high performance) filters 18 to be blown into a clean room 20 wherein the purified air flows down and passes through a grating floor 22 to be sent into an underfloor chamber 26. In this instance, there is a case where the purified air is warmed up by heat generated from equipment and the like or by heat generated artificially, and such warmed air once passes through the floor 22 by an inertial force to be sucked into the chamber 26. Since the warmed air is cooled down on the surface of a cold air layer A within the chamber 26, however, it does not ascend again from the chamber 26 into the clean room 20. The warmed air flows on the surface of the cold air layer A to be discharged through an opening 30 or into a circulation pipe 40. Accordingly, the downflow of the purified air is sufficiently maintained.
