The output of known cooling equipment cabinets fitted with air-to-air heat exchangers is not sufficient for hot climates. The proposed cooling system is bipartite, comprising a first set of cooling equipment that provides for closed cooling air circulation inside the cabinet, and a second set of cooling equipment that provides for open cooling air circulation inside the cabinet. For most of the year, cooling of the cabinet can be handled with the first set of cooling equipment, which consists of an air-to-air heat exchanger (100). For the short period of time that the heat exchanger alone cannot ensure sufficient cooling of the air inside the cabinet, the second set of cooling equipment will be employed to provide through-flow air circulation. This is achieved by drawing air into the cabinet through a filter (104) and blowing warmed-up air out. Because the period of time when the through-flow equipment needs to be used is short, it is not necessary to encase the equipment and the risk of the filters getting clogged is low, meaning that they need to be replaced less frequently. |
