摘要

The cooling air line (8) is installed in the cellar (12) of the building, and leads in to the refrigerator (5) or the freezer installed in an upper region (21). The cooling air line (8) includes a cooling air collection line (9), which is provided with several connection places (17), from which air supply lines (22) are led to the flow ducts (7) of one or more refrigerators (5). The cooling air line (8) has an outer branch line (8) leading to the external section (13) of the building (1), for the supply of external air, and an inner branch line (10) leading in the cellar region (12) of the building. A changeover valve (14) connected to the air collection line (9) is fitted between the two branch lines (10, 11), which depending on the required cooling air temp., can be changed over. ADVANTAGE - Efficiency of refrigerator is improved.
