Abstract:
An air duct system for a sleeping berth compartment and an air conditioning system for sleeping berth multiple units, relating to railway vehicle technology. The air duct system for a sleeping berth compartment comprises: a cross wall air duct (3) and a lower berth air duct (1); the cross wall air duct (3) is disposed in a cross wall of the sleeping berth compartment and extends along the height direction of a train body; an upper end of the cross wall air duct (3) is used for communicating with a branch air duct; a lower berth activity space is formed between a lower berth and a berth above the lower berth in the sleeping berth compartment; the lower berth air duct (1) is disposed on or in a wall surrounding and defining the lower berth activity space so that the lower berth air duct (1) can supply air to the lower berth; and one end of the lower berth air duct (1) is communicated with the cross wall air duct. In the system, the lower berth air duct (1) is provided on or in the wall of the lower berth activity space and one end of the lower berth air duct (1) is communicated with the cross wall air duct (3); therefore, the lower berth air duct (1) can sufficiently supply air to the lower berth.
