Abstract
Systems and methods for cooling an inverter of a variable frequency drive that drives a compressor in a cooling system for electronic equipment are disclosed. The system includes a first fluid circuit that cools electronic equipment using a first fluid flowing therethrough and a second fluid circuit that free cools a second fluid flowing therethrough. The second fluid circuit cools the first fluid using the free-cooled second fluid. The system further includes a third fluid circuit that mechanically cools the second fluid using a third fluid flowing therethrough as a function of the wet bulb temperature of atmospheric air. The third fluid circuit includes at least one compressor compresses the third fluid and is driven by a motor coupled to the variable frequency drive. At least a portion of the first fluid flowing through the third fluid circuit is diverted to cool the inverter of the variable frequency drive.
