Abstract
A refrigerant management system provides for optimal compressor performance by providing a compressor motor designed to operate at peak efficiency under a first cooling load and at least one sensor for generating a signal that indicates the actual cooling load. A controller is provided that determines any difference between the first cooling load and the actual cooling load from the sensor signal data. The controller is coupled to a refrigerant storage device to either add or remove refrigerant to maintain the system at or near the first cooling load in accordance with the signal form the first sensor indicating the actual cooling load. Consequently, the present invention provides for automatic adjustment of the amount of refrigerant in a cooling loop system to maintain a predetermined cooling load that allows operate a compressor motor to operate at its peak efficiency.
