Air Curtains and Doors for Distribution Centers: Mechanism, Application and Benefits
The air curtain acts as a thermal barrier that considerably reduces energy costs while raising the level of comfort and well-being. Primarily, they are used in industrial houses, warehouses, restaurants, shopping malls, commercial buildings and distribution centers. Depending on the size of the door and installation conditions, they are installed either horizontally or vertically. The sole purpose of this appliance is to secure the building from external contaminant and ensure that hot/fresh air is kept inside.
Benefits of Air Doors:
The integrated fans of the air curtain recover interior ambient air from below the ceiling and propel it through the conical nozzles. This process creates an air barrier against the exterior air while allowing free movement of people and equipment. In addition to the rate of efficiency (up to 70%) and maintaining the quality of the interior atmosphere, the fans consume very little electricity. This combination of performance allows the air curtain to surpass all conventional air.
Utilization of Air Doors in Different Areas:
Air doors are often used where doors are required to stay open for operational purposes, like loading docks and vehicle entrances. Heated air doors are commonly used when supplemental heat is needed for a space, and to reduce the wind chill factor across the opening in colder climates. Air curtains can be used to save energy by reducing the heat transfer (via mass transfer when air mixes across the threshold) between two spaces, although a closed and well-sealed physical door is much more effective. A combination is often utilized. An air door may pay for itself in a few years by reducing the load on the building's heating or air conditioning system. When the door is opened, the running air door minimizes the air flow from inside to outside and vice versa.
