It has the functions of cooling, dehumidifying, heating and humidifying, filtering and purifying, supplying and returning air, and introducing fresh air. It is mainly used in industry, medicine and health, large and medium-sized buildings, such as hotels, luxury commercial facilities, sports and entertainment centers and other places.

[0003] After checking the announcement number: CN220250281U, an air-conditioning box structure and an air-conditioning are disclosed. This technology discloses "including a box body and an inspection panel, a maintenance port is arranged on the top of the box body, the inspection panel includes an inspection part and a shielding part, the shielding part is installed on the left and right panels and the bracket of the nylon filter by screws, and the inspection part is arranged at the inspection port and other technical solutions, which have the characteristics that when the box body needs to be opened for inspection, one side of the inspection part is pulled up, and the other side of the inspection part is rotated relative to the box body to open the inspection port, so as to facilitate the maintenance of the electrical equipment in the box body. When the inspection part closes the inspection port, one side of the inspection part is rotated and connected to the box body, and the other side of the inspection part is fitted with the shielding part, so that the inspection port of the box body is in a closed state.
