The invention discloses a low-noise rail transit air conditioning unit and belongs to the technical field of a railway vehicle air conditioning unit. The air conditioning unit comprises a box body with an evaporation cavity and a condensation cavity, an air feeder, an evaporator and an electric heater are arranged in the evaporation cavity, a compressor, a condenser and a condensation fan are arranged in the condensation cavity, and the air conditioning unit is characterized in that the air feeder, the evaporator and the electric heater are sequentially arranged between an air return port andan air supply port in the evaporation cavity. The air conditioning unit is advantaged in that by changing a flowing mode of airflow between an air return opening and an air supply opening, the air feeder can be far away from the position of the air supply opening greatly, a low-noise backward centrifugal fan is adopted, noise at the air outlet of the unit can be greatly reduced, and more comfortable riding experience is provided for passengers, the whole air conditioning unit is low in noise, low in cost and low in failure rate, and competitiveness of products is effectively improved.
本发明公开了一种低噪音轨道交通空调机组,属于轨道车辆空调机组技术领域,包括具有蒸发腔和冷凝腔的箱体,在所述蒸发腔内设有送风机、蒸发器和电加热器,在所述冷凝腔内设有压缩机、冷凝器和冷凝风机,关键在于:所述送风机、所述蒸发器和所述电加热器依次设置在所述蒸发腔中的回风口和送风口之间。本发明的有益效果是:通过改变回风口与送风口间气流的流经方式,使送风机可以极大的远离送风口的位置,采用了低噪音的后向离心风机,可以极大的降低机组出风口处的噪音,为乘客提供更加舒适的乘坐体验;整个空调机组低噪音、低成本、低故障率,有效提升了产品的竞争力。
