1. Field of the Invention
The present invention relates generally to air conditioners and more specifically, to 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. The motors will run on the DC voltage generated by the generator.
The present invention is an air conditioning circuit having a fan driving a generator with the fan driven by the compressor discharge line gases. The generator has a DC output that powers the blower motor and the condenser fan motor.
