In this case, the air curtain 33 is a flat plate corresponding to the width of each of the nozzle 31 and the exhaust manifold 32.

The air collected by the exhaust manifold 32 is returned to the back of the ceiling 271 of the target space 27 by the circulation fan 34 through the circulation duct 35, and is sent into the interior of the target space 27 from the outlet 36 provided on the ceiling 271. Further, the air is exhausted by an exhaust louver 37 provided on the floor 272 to perform indoor ventilation.

In this case, a filter 38 may be provided at the outlet 36 or the circulation duct 35. Further, by forming the exhaust louver 37 provided on the floor 272 as a manifold and adding an exhaust fan, the air in the target space 27 can be forcibly exhausted.

According to such a configuration, the supply air branched from the supply air duct 28 to the duct 29 is supplied to the air supply fan 30 together with the air in the target space 27 taken from the intake manifold 311. Pressurized, ceiling 2
A flat jet having a predetermined width is jetted from the air supply nozzle 31 attached to the nozzle 71 into the target space 27 to form an air curtain 33 for isolating the target space 27 from others.

The jet air forming the air curtain 33 is collected in the exhaust manifold 32 provided on the floor 272 of the target space 27, and is forcibly returned to the ceiling 271 through the circulation duct 35 by the circulation fan 34. This time, the air is supplied from the outlet 36 to the target space 27 as ventilation air, and is further exhausted to the outside from the exhaust louver 37 provided on the floor 272, thereby performing indoor ventilation of the target space 27.

In this case, the air curtain 33
Is attracted into the jet air, and contaminated air may be partially mixed in during ventilation of the target space 27. Therefore, depending on the required level of the degree of contamination with respect to the supply of air to the target space 27, the problem is solved by providing a filter 38 in the outlet 36 or the circulation duct 35.

Therefore, by doing so, the object space 27
