Abstract

The vehicle air conditioner driving system comprises a microprocessor, a first driving unit, an inversion unit, a power conversion unit and a second driving unit, and the microprocessor, the first driving unit and the inversion unit form a driving loop of a compressor. The adopted principle is that direct-current voltage is converted into three-phase alternating-current voltage capable of driving and controlling a compressor, the microprocessor and the second driving unit form a driving loop of the fan, and the adopted principle is that the direct-current voltage is directly adopted to drive and control the fan. Therefore, the dual-motor driving function is achieved, the compressor and the draught fan can be driven and controlled at the same time, the rotating speed of the compressor and the rotating speed of the draught fan can be monitored in real time so that accurate speed regulation of the compressor and the draught fan can be achieved, the circuit is compact, the size is small, the integration degree is high, power is supplied only through a storage battery of the vehicle, and energy conservation and environment protection are achieved.

Description

technical field [0001] The invention relates to the technical field of vehicle air conditioners, in particular to a vehicle air conditioner drive system. Background technique [0002] Climate change and energy crisis are two major topics that people are generally concerned about in the world today. Under the dual pressure of energy and environmental protection, governments and vehicle companies in various countries regard energy saving and environmental protection as the inevitable direction of future vehicles. [0003] Vehicle air conditioning is an important part of the vehicle, which is responsible for providing a comfortable temperature environment for the driver and passengers. The original vehicle air conditioner on the vehicle uses the engine to drive the compressor, so that the temperature inside the vehicle can be cooled through the work of the entire air conditioning system. Although this type of vehicle air conditioner can achieve a better cooling effect, it will ...
