Improvement in air-conditioner for cabinets, is a model to be installed in different electrical panels, sideboards or cabinets (1), with a complement of emergency installation (2) for supplying electrical energy of direct current, then, all internal system of air-conditioning (3), besides establishing an internal refrigeration air flow (4), it is also fed by alternating current (AC), when the equipment is in normal operation state, however, if there are failures (defects) in the air-conditioning or there are lack of alternating current (AC), an electrical system of commutation makes one part of the air-conditioning (3) to be fed with direct current (DC) supplied by emergency installation accumulators (2), consequently, one emergency operation emergency condition is established together with one or more fans, so that internal temperature of the cabinet may be kept inside the strip that does not compromise equipment operation integrity of the equipment inside the cabinet. |
