Modularized air conditioning unit sealing structure and air conditioning unit

The invention discloses a modularized air conditioning unit sealing structure. Through the improvement on a connecting structure between two adjacent sub systems, a set of externally-mounted wind shield plates is used for connecting the two adjacent sub systems; a set of built-in wind shield plates is arranged in one sub system, so that the two sub systems share one set of wind shield plates; and the built-in wind shield plates and the externally-mounted wind shield plates are simultaneously combined for achieving the condenser sealing goal. Compared with a method in a sealing mode of using independent built-in wind baffle plates by all condenser components and in an assembly mode of adopting direct and simple splicing joint between the sub systems in the prior art, the modularized air conditioning unit sealing structure has the advantages that the connecting structure is simplified; one set of built-in wind shield plates in the two adjacent sub systems is omitted; the length of the whole machine can be effectively shortened; the size, the weight and the cost of an air conditioning unit are reduced; and the requirements of the air conditioning unit on the installing environment and the transportation condition are reduced. The invention also discloses the air conditioning unit adopting the modularized air conditioning unit sealing structure. Compared with the prior art, the air conditioning unit has the advantage that the whole unit length is shortened by about 360mm.
