The invention relates to a cooling system for cooling data centers (1), which cooling system includes an air liquid heat exchanger for transferring the heat from the air circulation cooling the data center into the liquid and means for cooling the liquid. According to the invention, the means for cooling the liquid include a heat recovery module (2) including a compressor circuit (3), into a primary circuit (4) of which the liquid to be cooled is conveyed and a secondary circuit (5) of which is connected to a heat use (6). In addition, a return channel (7) of the primary circuit includes a controlled return circulation (8) for returning the liquid exceeding a specific temperature to the primary circuit and for conveying the liquid below this specific temperature back to a liquid channel (9) provided from the data center. Further, the liquid channel (9) from the data center includes a direct flow connection past the recovery module (2) to a backup cooling device (10,11,12) provided with a return channel (13) for conveying the cooled liquid to the air liquid heat exchanger of the data center. |
