The role and efficiency of the air curtain system in optimizing the energy consumption of buildings (residential, commercial and government buildings)
Official reports show that the building sector (residential, commercial and public buildings) accounts for 41% of energy consumption.
The main part of this energy consumption is the building sector, which includes space heating (37%), space heating (10%), water heating (12%) and lighting (9%), which accounts for about 70% of the cost The energy gains the building. For commercial buildings, air penetration can be up to 18 percent of the total energy waste. Air penetration (or air leakage) is often due to the accidental penetration of air from the outside air into a building through the door slot or the entrance of the building. These buildings include restaurants, retail stores, supermarkets, offices and hospitals.
Air curtains that are typically installed on top of the doors separate indoor and outdoor temperatures. The airflow is designed to be fully strategically designed to hit a specific speed and position. The air curtain prevents the air from penetrating into the interior and at the same time allows the air to flow outside the building. The air curtain for wide door entry / exit is also applicable. This device prevents the entry of insects, dust, cold winds, and humidity to the outside environment. Inspections have shown that the entrances equipped with air curtains more energy than the inputs of this device They do not hold and generally affect the energy consumption of the building.
