<P>PROBLEM TO BE SOLVED: To provide a negative pressure type closed space forming system which does not leak contaminated air directly out of a closed space, inhibits the influence of purified air of this contaminated air on a non-closed space and the closed space as low as possible and can reduce the air conditioning load by reducing the discharge of the air in the closed space to the outside. <P>SOLUTION: The system is configured to be installed in an indoor space A, forms a closed space 3 using an air curtain 2 in at least a part of the space A, discharges air in this closed space 3 to the outside to hold the inside of the closed space 3 in a negative pressure state, purifies air discharged from the inside of the closed space 3 to the outside with an air purifier 20, discharges the purified air from an air discharge port provided adjacently to an boundary face 2a on the opposite closed space side of the air curtain 2 along the boundary face 2a, and circulates and utilizes this discharged air 5 as external entrainment air of the air curtain 2, so that the air is purified by the air purifier 20 each time. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
