According to the cab air conditioning unit, the cab and the railway vehicle, an evaporation cavity is integrated in a machine shell, the machine shell is further provided with an air supply assembly, an air return opening and a fresh air opening, one end of the air supply assembly and one end of the air return opening communicate with the evaporation cavity, and the other end of the air supply assembly and the other end of the air return opening communicate with the interior of the cab; air supply in the cab can be achieved without additionally arranging an independent air supply duct machine shell. Meanwhile, the bottom wall, corresponding to the outer side of the air supply assembly, of the machine shell is concave inwards and is opposite to the cab vehicle body to form an air return cavity, so that a cavity between the interior top plate and the cab vehicle body can be communicated, the air return area is effectively increased, and the air return effect is improved; and secondly, the air supply assembly and the air return opening are integrated at the bottom of the machine shell, an air conditioning unit mechanism is optimized, the overall size is reduced, the overall weight is reduced, and the weight of the railway vehicle is further reduced.
本申请实施例中提供了一种司机室空调机组、司机室及轨道车辆,在机壳内集成有蒸发腔室,机壳还设有送风组件、回风口和新风口,送风组件和回风口的一端均与蒸发腔室连通,另一端与司机室内部连通,其无需额外设置单独的送风道机壳实现司机室内部的送风;同时,送风组件的外侧对应的所述机壳的底壁内凹、并与司机室车体相对形成回风腔室,以能够对内装顶板和司机室车体之间的空腔连通,有效增加回风面积,提高回风效果;其次,将送风组件和回风口集成在机壳的底部,优化空调机组机构,缩减整机尺寸,降低整机重量,进一步减轻轨道车辆的重量。
