ーテンを形成することができる。<Function> Air forced through the supply duct from the air source enters the porous damper in the wind pressure supply chamber, and is uniformly pumped throughout the air pressure supply chamber by the porous damper. Furthermore,
The pressure inside the wind pressure supply chamber is equalized by a resistor provided on the lower surface of the wind pressure supply chamber, and the pressure in the wind pressure supply chamber is uniformly blown out from the entire surface of the wind pressure supply chamber to the lower intake chamber in a laminar flow. The air is then filtered and sucked into the intake chamber, and then circulated again through the intake duct to the blowing source. In particular, stratified air that is wider than the wind pressure supply chamber is pumped out, thereby creating a stratified air curtain. can be formed.

に構成している。The drawings relate to the present invention, and FIG. 1 is a perspective view of the entire air curtain equipment. In the figure, one end of a supply duct 4 is connected to the upper air blowing side of the air source 3, and the other end of the supply duct 4 is connected to the wind pressure supply chamber I and is directed downward; Intake chambers 2 are disposed at opposing positions, and the inlet chambers 2 and the suction side of the blower source 3 are connected by an inlet duct 5, so that air circulates throughout the air curtain equipment.

The air filters 7 and 8 are made of a known material, such as a urethane filter or a fibrous activated carbon filter.

に均一に圧送するためのものである。Furthermore, a porous damper 10 as shown in FIG. 3 is installed inside the air pressure supply chamber 1 so as to face the opening of the supply duct 4. This porous damper IO may be, for example, a cloth bag, and the cloth bag temporarily stops receiving the air pressurized from the supply duct 4 to prevent the pressurized air from flowing out into the wind pressure supply chamber l at once, as shown in FIG. 3a. This is for uniformly feeding the entire air pressure supply chamber 1 as shown in FIG.

持して形成されている。Further, a resistor 9 is installed on the lower surface of the wind pressure supply chamber 1 so as to be located below the porous damper 10. This resistor 9 has a structure as shown in FIG. 2, and is formed by sandwiching a porous filter 13, such as a sponge, between top and bottom between strings 12, and then sandwiching this between top and bottom between a frame 11. has been done.

室１内の空気が一気に下方へ流出せず、風圧供給室１内
の空気圧は適度に保たれる。The air forced into the wind pressure supply chamber 1 passes through the resistor 9 and is blown toward the lower intake chamber 2, but due to the action of the porous filter 13 forming the resistor 9, The air inside the air pressure supply chamber 1 does not flow downward all at once, and the air pressure inside the wind pressure supply chamber 1 is maintained at an appropriate level.

択すれば工場等の施設は常に清浄な状態に保たれる。When installed in facilities such as factories and laboratories, as shown in Figure 4, a layered curtain base is formed over the length of the curtain, so even if the curtain layer between A and A' is broken and outside air is Even if air enters, outside air can be blocked between B and B', between c and c', or between D and D', so that it cannot infiltrate to facility R such as a factory. Even if a part of the curtain layer is broken and outside air enters, the outside air is sucked into the air intake chamber 2 within the length L of the curtain and is filtered by the air filter 7 and the porous filter 13. Therefore, if the length of the curtain is selected depending on the intended use of the present invention, facilities such as factories can be kept clean at all times.

ルブ■を設けて流路面積を絞る方法などがある。Further, by forming the curtain base in layers, a sufficient blocking effect can be obtained without increasing the wind speed as in the conventional example, so a wind speed control mechanism may be provided. This wind speed control method includes a method of controlling the number of rotations of a blower fan using an inverter (not shown), or a method of providing a butterfly valve (2) in the intake duct 5 to narrow down the flow path area.

る。Effects> As is clear from the above explanation, the present invention replaces the conventional linear air curtain with a layered air curtain, which improves the ability to block outside air, and is suitable for clean rooms that require this.
If attached to facilities such as factories and laboratories, it will not only be possible to keep the inside of the facility clean without causing tail flow phenomenon without particularly increasing the wind speed, but also improve heating and cooling efficiency.

するので、施設内の作業環境が悪化する虞れはない。In addition, the entire air curtain equipment is of a circulation type, and even if outside air enters, the air is filtered and circulated again due to the filtering effect of the upper surface of the intake chamber and the resistor, which reduces the risk of deteriorating the working environment within the facility. There is no such thing.
