Abstract

The embodiment of the present invention discloses an air-conditioning system, including: an air-conditioning unit, a motor electronically controlled heat dissipation unit, and a motor electronically controlled heat dissipation and heat recovery switching unit; the air-conditioning unit is used to heat or cool air; To dissipate heat from the associated motor and control system, when the motor electronically controlled heat dissipation and heat recovery switching unit is switched to heat recovery mode, the motor electronically controlled heat dissipation unit is also used to transfer the heat dissipated by the associated motor and control system to the air conditioning unit so that the air-conditioning unit uses the heat to heat the air; the motor electronically controlled heat dissipation and heat recovery switching unit is used to control the working mode of the motor electronically controlled heat dissipation unit. Through the above-mentioned air-conditioning system, not only air-conditioning refrigeration or heating is realized, but also the associated motor and control system can be dissipated, and the heat generated by the motor and control system can be recycled, reducing system cost and complexity. Improved energy efficiency.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of automobile air conditioning, and in particular to an air conditioning system. Background technique [0002] With the continuous increase of automobile consumption, traditionally relying on burning gasoline, diesel and other fossil fuels to provide power, not only consumes a lot of energy, but also emits a large amount of automobile exhaust, causing environmental pollution and becoming one of the main causes of smog. one. Therefore, energy-saving and environment-friendly new energy vehicles are increasingly favored by the government and society, especially the pure electric vehicles that are currently being used in large quantities. Pure electric vehicles rely on the power battery pack to provide power for the motor, and at the same time provide power for the vehicle's air conditioning system and control system. As an energy storage element, the battery pack is a key component of a ...
