ABSTRACT:
A universal direct current brushless air conditioning system preferably includes a blower unit and a compressor unit. The blower unit preferably includes an evaporator, at least one inlet fan, at least one outlet vent, a direct current controller, a thermostatic expansion valve and a mounting enclosure. The compressor unit preferably includes a compressor, a condenser, at least one exhaust fan and a mounting enclosure. The compressor includes a motor. Significantly, the inlet fans, the at least one exhaust cooling fan and the compressor motor are a DC brushless type for drawing less electrical power. The blower unit and compressor unit are connected to each other through any suitable tubing and wires. A reverse valve is preferably included to allow the universal direct current brushless air conditioning system to be used as a heat pump to output heat.
