    摘要： An air conditioning unit that will be more efficient by generating its own voltage. The present invention is a way to make an air conditioning unit more efficient by placing an actuator in line with the expanding refrigerant gas in communication with a generator that will generate a direct voltage (DC) that will in turn drive the two fan motors that most air conditioning units have.

    摘要： A method and system for reducing windage losses in compressor motors is provided. The compressor motor is cooled by circulating refrigerant from a closed refrigerant loop incorporating the compressor. A pumping device coupled to a liquid expander in the closed refrigerant loop circulates refrigerant through the motor cavity and produces a motor cavity pressure lower than evaporating pressure. The lower pressure in the motor cavity reduces the density of the gasses in the motor cavity, resulting in reduced windage losses of the motor. Additionally, the pumping device is powered by the recovered liquid expansion energy between the condenser and the evaporator.
