The invention discloses a ventilated air conditioning wall for a multi-storey building. The ventilated air conditioning wall comprises a water supply device and a heat exchange wall, wherein the water supply device comprises a water supply pipe, a flow regulating valve and a spray device, the flow regulating valve is arranged on the water supply pipe, and the spray device is communicated with the water supply pipe; the heat exchange wall comprises an external thermal insulating wall, an internal thermal insulating wall, a filtering drainage piece, an air inlet, a ventilated heat exchange interlayer, an activated carbon filtering layer and an air induced feeder, a gap between the external thermal insulating wall and the internal thermal insulating wall serves as the ventilated heat exchange interlayer, the activated carbon filtering layer and the filtering drainage piece are arranged in the ventilated heat exchange interlayer, the air inlet is arranged on the external thermal insulating wall, and the air induced feeder is arranged in the internal thermal insulating wall; the spray device is arranged in the ventilated heat exchange interlayer, and located between the activated carbon filtering layer and the filtering drainage piece; and the part, below the air inlet, of the ventilated heat exchange interlayer serves as a water return pool, and a water return pipe is communicated with the water return pool through a water return regulating valve. According to the invention, air is subjected to heat exchange and humidification through spraying cool water to an inner cavity of a wall in summer and spraying hot water to the inner cavity of the wall in winter, and then the air is fed indoors so as to achieve the purpose of ventilated air conditioning.
