Inside will be each model individually:

with two fans - Verts: 5371, Faces: 4781.
The archive contains all the conditioner individually in different formats. In the models there are triangles and ngons, but only in the most necessary and inconspicuous places, the rest of the geometry consists of quads. Video rendering was done in Eevee with low quality.
