Description

Technical Field

[0001] This utility model belongs to the field of air conditioning equipment technology, and in particular relates to an air inlet flange. Background Technology

[0002] In air conditioning systems, terminal equipment, as part of the system, needs to circulate and exchange heat with indoor air. When the air-conditioned area is far from the terminal equipment, supply and return air ducts need to be installed. To connect to the ducts, air vent flanges are usually installed at the supply and return air inlets of the air conditioning unit, and filters are installed inside the flanges, which can be pulled out from the side for replacement. These flanges are generally installed directly onto the unit from the outside, creating a protrusion that causes the maximum size of the equipment to exceed the unit's dimensions, increasing the overall unit size. Furthermore, because of this protrusion, padding is needed in the packaging to prevent damage to the air vents, increasing the packaging thickness and costs. Additionally, the protrusion causes the final packaged size of the equipment to exceed the unit's dimensions, increasing shipping costs.

[0003] The bulge in the air conditioning unit is caused by the fact that after the air vent flange is installed on the unit, the flange body is located outside the unit, which inevitably causes the outer side of the air vent to protrude above the unit panel. Summary of the Invention
