The invention provides an electric vehicle and a noise reduction air conditioning system and noise reduction method thereof, the noise reduction air conditioning system comprises an air conditioning module and a noise reduction module, and the air conditioning module comprises an air conditioner, an air outlet duct and an air return duct; the noise reduction module comprises a noise monitor, an air conditioner controller, a noise processing module and a playing module, the air conditioner controller, the noise processing module, the playing module and the noise monitor are in communication connection, and the noise monitor is installed in the air outlet duct and/or the air return duct; the air conditioner controller obtains the operation state of the air conditioner module by receiving noise information collected by the noise monitor. The noise processing module is used for receiving the noise information and converting the noise information into a corresponding audio waveform signal; the playing modules are used for receiving audio waveform signals and outputting noise reduction sound waves with the same frequency and the opposite phase as the audio waveform signals, and the playing modules are installed at the air outlet duct and/or the air return duct. The noise reduction air conditioning system solves the problem that the noise reduction effect of the whole environment in an existing electric vehicle is poor.

    本发明提出了一种电动车及其降噪空调系统和降噪方法,该降噪空调系统包括空调模块和降噪模块,空调模块包括空调、出风风道和回风风道;降噪模块包括噪声监测器、空调控制器、噪声处理模块和播放模块,空调控制器、噪声处理模块、播放模块和噪声监测器之间通信连接,噪声监测器安装于出风风道和/或回风风道;空调控制器通过接收噪声监测器采集的噪声信息获取空调模块的运行状态;噪声处理模块用于接收噪声信息并将噪声信息转换为相对应的音频波形信号;播放模块用于接收音频波形信号并输出与音频波形频率相同、相位相反的降噪声波,出风风道和/或回风风道处安装有播放模块。本发明的降噪空调系统解决了现有的电动车内整体环境降噪效果差的问题。
