Description

technical field [0001] This case belongs to the field of air conditioning, and involves the sealing structure of the side-opening maintenance door (or window) of the box of the air conditioning unit, especially suitable for the combined air handling unit. Background technique [0002] For mature industrial technologies such as air conditioners, the audience is more pursuing the improvement of product details, although the improvement of details is more difficult, such as the sealing problem of the inspection door in the air conditioner box. [0003] The casement inspection door (or window) mentioned in this case refers to a door (or window) whose hinges (or hinges) are mounted on the side of the door and open inwards or outwards. It is generally known in the art that there is no essential difference between the inspection doors and inspection windows described here, and they are collectively referred to as inspection doors hereinafter. [0004] Prior art such as disclosed C...

AI Technical Summary

Problems solved by technology

[0016] 1. Sealing problem. Due to the large pressure difference between the inside and outside of the central air-conditioning unit box, the problem of air leakage needs to be solved urgently

[0017] 2. The problem of tooling, the central air-conditioning unit box body is huge, so there is an urgent need for a door leaf and door frame assembly that not only has a sealed structure, but also has a simple structure and better assembly adaptability to working conditions.

[0018] 3. The problem of door leaf deformation and drooping. Drooping and deformation of the door leaf of the swing door is a common problem, so it needs to be solved urgently

[0019] Due to its structure, the existing technology cannot overcome the above problems well
