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, comprising:
- an air conditioner having a compressor, an evaporator, and at least one heat exchanger associated with ambient air or open water heat exchange;
- an input bus from one or more modules which provides a configuration message or a dynamic message;
- a driver associated with each of an inverter compressor motor of the compressor, a first brushless DC motor of the evaporator, and a second brushless DC motor of the at least one heat exchanger;
- a controller that controls the compressor, the evaporator and the at least one heat exchanger;
- wherein the controller derates power output based on an amount of available power and input from the input bus.
An air conditioning device, comprising:
- a main body;
- a blower including an inlet and an outlet;
- 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 and in air communication with said blower;
- an evaporator in fluid communication with said compressor and in air communication with said blower;
- a heat exchanger in fluid communication with said refrigerant conduit, said compressor, and said evaporator, said heat exchanger being a condenser for exchange of refrigerant heat to atmosphere;
- a dual voltage input for alternating current (AC) and direct current (DC);
- and,
- an auto-tuning function which selects output power based on available input power.
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 in fluid communication with said compressor and in air communication with said blower;
- a heat exchanger in fluid communication with said refrigerant conduit, said compressor, and said evaporator, said heat exchanger being a condenser which exchanges refrigerant heat to atmosphere;
- 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.
