Air conditioning unit

The utility model relates to the technical field of air conditioners, in particular to an air conditioning unit which can solve the problems that when only a surface air cooler in an air conditioning host is used for dehumidification, the dehumidification efficiency is low, and the humidity requirement of a clean room is difficult to meet to a certain extent. The air conditioning unit comprises an air inlet pipeline, an air conditioning host and an air outlet pipeline which are sequentially connected in the fresh air inlet direction. The air inlet pipeline comprises a first air inlet pipeline and a second air inlet pipeline, a dehumidification device is arranged on the second air inlet pipeline, and the dehumidification device is used for dehumidifying air entering the second air inlet pipeline; the ends, away from the air conditioner host, of the first air inlet pipeline and the second air inlet pipeline are each provided with a first adjusting valve used for adjusting the air inlet flow of the air inlet pip
