Abstract: The present invention describes a cooling system integrated for cabinets and a cooling cabinet by forced air. Specifically, the present invention includes a cooling system presented in a hot region including a cooling fluid compressor set and cooling fluid condensation medium, and a cold region including heat exchanger, ventilation mean, air inlet and air outlet, in a way that the configuration of element allows the cooling system to present a reduced size consuming low internal volume of a cabinet, when installed on the same. The present invention is situated on the technical field of thermodynamic systems and cabinet refrigeration.
