Abstract

Pressurizing system for producing an air curtain for energy saving. It comprises a mechanism arranged between a door and an inner wall of a cooling chamber or refrigerator, and it comprises a fixed element, a moving element attached to the door and a compressing element between the fixed element and the moving element. The system is provided with orientable holes arranged in the frame of the refrigerator opening connected to the mechanism, such that, when the door opens the air curtain is produced with the air that has been compressed using the mechanism and that comes out through the orientable holes, thus preventing the cool air from the cooling chamber or refrigerator from being lost.
