Combined air conditioning unit

The invention provides a combined air conditioning unit, and belongs to the technical field of air conditioning units. Comprising a rack, one side of the rack is connected with an air inlet and a filtering device, and the other side of the rack is provided with a first draught fan, a second filtering section, a surface air cooler, a dehumidifier, a condenser and a second draught fan. And a controller electrically connected with the first fan, the surface air cooler, the dehumidifier, the condenser and the second fan is mounted at the front end of the rack. By arranging a baffle and a positioning spraying mechanism, the whole filter plate is mounted in a clamping manner, meanwhile, a moving space is provided, the filter plate is convenient to dismount and mount, under the vibration action of the filter plate and the heating action of an electric heating plate, the drying time of the filter plate is shortened, the situation that the wet filter plate more easily adsorbs dust is avoided, and the service life of t
