The compressor in a refrigeration system is controlled solely by a variable speed drive which controls the motor of the compressor by virtue of the varying of the frequency of the electricity provided to the motor. To minimize the initial cost and to minimize operating costs, the variable speed drive is cooled by refrigerant from the refrigeration system which permits the use of a smaller drive, and the variable speed drive is operated at, or approaching, a unity power factor.

A compressor for compressing refrigerant in an air conditioning or refrigeration system, including a housing having a suction port, a discharge port, and a compression chamber, a mechanism for producing a compression cycle for compressing the refrigerant, wherein the compression cycle occurs in the suction port, discharge port and compression chamber, and a mechanism for providing liquid refrigerant into the compression cycle at a desired location for reducing pressure pulsations and associated radiated noise produced during the compression cycle.

A discharge collector and diffuser for a screw compressor, including a housing having an inlet for receiving flow from a compressor and an outlet and defining therebetween a collector portion, a transition portion and a diffuser portion, the collector portion being adapted to receive a plurality of non-parallel streams from a compressor and to guide the streams into a substantially parallel flow direction, the housing further having a splitter plate positioned in the collector portion to separate the non-parallel streams from each other, whereby the streams are maintained separate until they are substantially parallel, thereby reducing flow losses.
