The invention relates to the technical field of railway vehicle air conditioning systems, and provides a noise reduction method for an air conditioner of a high-speed motor train unit, which comprises the following steps: step 1, when air conditioner fan blades enter a low-speed rotating mode, a first electric sliding door slides towards two sides, an electric push rod pushes a connecting pipe to approach the air conditioner fan blades, and the air conditioner fan blades rotate to drive the first electric sliding door to rotate; the two rotary cleaning brushes rotate towards one side at the same time to clean dust attached to the surfaces of the air conditioner fan blades. Secondly, when dust on the surfaces of the air conditioner fan blades is cleaned, a blowing and sucking machine is started to adsorb the dust in the cleaning process, and air full of the dust is filtered; and thirdly, when the dust on the surfaces of the air conditioner fan blades is cleaned, the reciprocating cleaning brush swings back and forth to scrape the dust falling on the blocking net. Through rotation of the air conditioner fan blades, the two rotary cleaning brushes rotate towards one side at the same time to clean dust attached to the surfaces of the air conditioner fan blades, the blowing and sucking machine adsorbs the dust in the cleaning process and filters air full of the dust, accumulated dust is reduced, airflow is more stable when the fan works, and therefore noise is reduced.

    本发明涉及轨道车辆空调系统技术领域,提供一种高速动车组空调的降噪方法,包括以下步骤:步骤一、当空调扇叶进入低速旋转模式时,第一电动滑门向两侧滑动,电动推杆推动连接管向空调扇叶靠近,通过空调扇叶旋转,两个旋转清洁刷同时向一侧旋转对空调扇叶表面粘附的灰尘进行清理;步骤二、当空调扇叶表面的灰尘被清理时,启动吹吸机对清理过程中的灰尘进行吸附,对充满灰尘的空气进行过滤;步骤三、在空调扇叶表面的灰尘被清理时,往复清洁刷来回摆动对掉落在阻拦网上的灰尘进行刮蹭。通过空调扇叶旋转,使两个旋转清洁刷同时向一侧旋转对空调扇叶表面粘附的灰尘进行清理,吹吸机对清理过程中的灰尘进行吸附,对充满灰尘的空气进行过滤,使积尘减少,风扇工作时的气流更加稳定,从而减少噪音。
