Referring to fig. 1, in an embodiment of the present invention, the air handling unit further includes an air conditioner body 2000, the air conditioner body 2000 and the filter screen assembly 1000 are detachably connected to realize a modular design, such as a filter module, a heat exchange module, etc., wherein the filter screen assembly 1000 belongs to a part of the filter module. It can be appreciated that the screen assembly 1000 is removably attached to the air conditioner body 2000 to facilitate handling of the air handling unit. The air handling unit is disassembled into a plurality of parts, so that the air handling unit is favorable for single person carrying, narrow passageways and other scenes. It should be noted that the filter screen assembly 1000 may be disposed at the lower end or the upper end of the air conditioner body 2000, and a suitable mounting position is selected according to actual conditions.

Referring to fig. 1 and 2, in an embodiment of the present invention, the filter screen assembly 1000 and the air conditioner body 2000 are detachably connected by means of the buckle 300. For example, the buckle 300 has a plurality of buckles arranged around the outer circumferential wall of the box 100, and when the filter screen assembly 1000 is connected to the lower end of the air conditioner body 2000, the buckle 300 protrudes from the upper end of the box 100, so that the buckle 300 can be clamped with the air conditioner body 2000, thereby fixing the relative positions of the filter screen assembly 1000 and the air conditioner body 2000; when the filter screen assembly 1000 is connected to the upper end of the air conditioner body 2000, the buckle 300 is disposed on the air conditioner body 2000, and the buckle 300 of the air conditioner body 2000 is clamped to the filter screen assembly 1000, so as to fix the relative positions of the filter screen assembly 1000 and the air conditioner body 2000.

Referring to fig. 2, in the embodiment of the present invention, the outer wall of the box 100 is provided with a groove 113, and the buckle 300 is disposed in the groove 113 to improve the integrity and the aesthetic appearance of the box 100.

Referring to fig. 8, in the embodiment of the present invention, the first frame 140 is provided with a positioning groove 141, and the second frame 150 is provided with a positioning protrusion (not shown). When the air conditioner body 2000 is connected with the filter screen assembly 1000, the positioning groove 141 of the first frame 140 or the positioning protrusion of the second frame 150 can play a positioning role, so that the filter screen assembly 1000 and the air conditioner body 2000 can be aligned quickly, and the installation efficiency is improved.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
