Patent ID: 7895854

Claim:
An electronics cabinet for housing a plurality of air-cooled electronic components, said electronics cabinet comprising: an inlet section through which air is configured to flow into the electronics cabinet; an outlet section through which air is configured to flow out of the electronics cabinet; and a refrigeration system for controlling airflow around the electronics cabinet through at least one of the inlet section and the outlet section, said refrigeration system comprising: a refrigerant line positioned in the at least one of the inlet section and the outlet section, wherein the refrigerant line is split into second refrigerant lines over a portion of the refrigerant line, the second refrigerant lines being arranged in a parallel configuration with respect to each other; a variable speed compressor for controlling the flow of refrigerant through the refrigerant line; evaporators positioned along the second refrigerant lines, said evaporators being positioned directly in the path of airflow around the components housed in the electronics cabinet through the at least one of the inlet section and the outlet section; a controller for controlling the speed of the variable speed compressor; and a temperature sensor positioned to detect air temperature at a location with respect to an interior section of the electronics cabinet, said temperature sensor also being configured to transmit signals related to the detected temperature to the controller, wherein the controller is configured to vary the speed of the variable speed compressor based upon the signals received from the temperature sensor.
