A refrigeration system for controlling airflow around an air-cooled heat generating device having a plurality of components includes a refrigerant line split into second refrigerant lines, which are arranged in a parallel configuration with respect to each other. Evaporators are positioned along the second refrigerant lines and in the path of airflow supplied into the components or airflow exhausted from the components. The refrigeration system further includes a variable speed compressor and a controller for controlling the speed of the variable speed compressor. Furthermore, the refrigeration system includes a temperature sensor configured to transmit signals related to a detected temperature to the controller, and the controller is configured to vary the speed of the variable speed compressor based upon the detected temperature.
