Abstract:
A refrigeration system for a temperature-controlled storage device includes a refrigeration circuit, a cooling circuit, and a controller. The refrigeration circuit includes a compressor driven by a brushless DC motor operable at multiple different speeds, a first heat exchanger, an expansion device, and a cooling unit in fluid communication via a first working fluid. The cooling circuit includes a pump and a second heat exchanger in fluid communication with the first heat exchanger via a second working fluid such that the first heat exchanger is liquid-cooled by the second working fluid. The controller operates the brushless DC motor at multiple different speeds to accommodate multiple different thermal loads experienced by the refrigeration system. Each of the speeds corresponds to a different thermal load. The controller modulates the speed of the brushless DC motor to maintain a desired temperature of a temperature-controlled space within the temperature-controlled device.

Claim (Index 7):
A refrigeration circuit for a temperature-controlled storage device, comprising:\n a compressor configured to circulate a first working fluid through the refrigeration circuit; a variable-speed brushless DC motor operable to drive the compressor; a heat exchanger configured to receive the first working fluid from the compressor and provide cooling for the first working fluid; a valve operable to modulate a flow rate of a second working fluid through the heat exchanger; an expansion device configured to receive the cooled first working fluid from the heat exchanger and expand the first working fluid to a lower-temperature state; a cooling element configured to receive the expanded first working fluid from the expansion device and provide the first working fluid to the compressor; and a controller configured to operate the variable-speed brushless DC motor at multiple different speeds to accommodate multiple different thermal loads, each of the speeds corresponding to a different thermal load, wherein the controller is configured to modulate a speed of the brushless DC motor to maintain a desired temperature of a temperature-controlled space within the temperature-controlled storage device, and the controller is configured to operate the valve to maintain the measured pressure of the first working fluid at the inlet of the first heat exchanger at a desired pressure; wherein the compressor, the heat exchanger, the expansion device, and the cooling element are in fluid communication via the first working fluid.
