The invention relates to an urban rail vehicle air conditioning and ventilation system and an urban rail vehicle. The urban rail vehicle air conditioning and ventilation system comprises an air conditioning unit, an air supply duct and a return air duct; an air supply outlet and an air return inlet are formed in the air conditioning unit; the air conditioning unit is fixedly installed on a vehicle steel structure; a space defined by a side top plate and/or middle top plate in a guest room and the vehicle steel structure is taken as the air supply duct; a vehicle inner air supply outlet for supplying air to the guest room and a vehicle inner air return inlet are formed in the corresponding side top plate and/or the middle top plate; the air supplying outlet of the air conditioning unit and the vehicle inner air supplying outlet are communicated with the air supply duct; and the vehicle inner air return inlet is communicated with the air return inlet of the air conditioning unit through the return air duct. According to the urban rail vehicle air conditioning and ventilation system, an in-built top space is reasonably used, a problem that the air supply duct cannot be arranged on the top of the guest room, and a separated duct structure can be omitted; the cavity between the in-built top plates and the vehicle body is used for supplying air, the weight is reduced, and the cost is saved; and moreover, the height between the top plates and the vehicle body can be lowered, so that the height of the vehicle is lowered, and limiting requirements of the vehicle are met.
