Abstract
Present embodiments relate to an air conditioning system for a vehicle. More specifically, but without limitation, present embodiments relate to a vehicle air conditioning system which comprises a variable speed motor and a controller which is capable of auto selecting an input current and which auto tunes according to the AC or DC voltage presented at the input. A controller is also provided which is capable of controlling two or more motors for an air conditioning system.
Claims18
An air conditioning device for a vehicle including:
- a main body;
- a blower including an inlet and an outlet, the blower further including blades rotating therein;
- a compressor located on said main body;
- a variable speed motor operably connected to said compressor, said variable speed motor driving rotation of said compressor;
- a refrigerant conduit in fluid communication with said compressor;
- an evaporator positioned on said main body, said evaporator in fluid communication with said compressor and in air communication with the inlet of said blower;
- a heat exchanger in fluid communication with said refrigerant conduit, said compressor, and said evaporator, said heat exchanger being a coil-in-coil open water heat exchanger;
- at least one additional motor;
- a controller having a dual voltage input for alternating current (AC) and direct current (DC), said controller operating said variable speed motor and said at least one additional motor.
