The use of air curtains has now become common at work premises, storage areas and industries for keeping the temperature of the place cool and relevant.
The device blows a good amount of air that stops insects, flies and pollutants from entering inside the place. They are especially mounted to keep the environment clean and dust free. They control the flow of warm and cold air as per the climatic conditions outside.
An air curtain is the electronic device that is fan-powered and it creates an invisible barrier over the doors and windows that limits the entry of fumes, flies and other pollutants inside the resident, industrial buildings and commercial places.
It is a continuous broad stream of air circulated across the doorway of a conditioned space that reduces penetration of insects and unconditioned air into the conditioned space. It forces an airstream over the entire entrance that blocks the path of insects and flies.
How Do Air Curtains Work?
The device runs on electricity but consumes low electrical units as compared to other air cooling devices. If we talk about the working of an air curtain then it consumes different units and voltages as per the model.
The device is equipped with two or more fans that extracts all the warm air along with dirt and pollutants and flows out cool and fresh air in the atmosphere.
The air door has a grille that helps to easily extract the bad odor, fumes and dust which is compressed by the internal fans. It has a filter that cleans the air and then circulates it in the atmosphere. The most common types of flow are axial, centrifugal and cross-flow.
The air stream works with a velocity and angle such that any air that tries to penetrate the curtain is restricted.
It should be placed at the right angle so that the entire room gets proper ventilation. They can be mounted horizontally or vertically depending on the flow of the air. Usually the air curtains are placed horizontally above the openings of the door and windows so that it breaks the chain of dirt and dust in the place.
