Module for an air handling unit and air handling unit including such a module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air handling units face challenges in preventing air leaks at connection posts, which requires expensive and short-lived sealant application during assembly, and the used materials are not eco-friendly.
Innovation Solution
Incorporating rectilinear sealing gaskets into the bases of connection posts, which attach to the upper and lower surfaces of the module, eliminating the need for additional sealant and enhancing the sealing functionality between the fins and the module surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sealant is applied during assembly to prevent air leaks at connection posts, then sealing effectiveness is improved, but manufacturing cost increases and the solution becomes less durable
Solution Approach 1:
The sealing function is merged with the base component by integrating a sealing gasket directly into the base structure. The base now performs both its structural function (attaching the post to panels) and the sealing function (preventing air leaks), eliminating the need for separate sealant application and reducing manufacturing complexity and cost.
2Reliability
If sealant is used to seal the space between fins and panel surfaces, then air leak prevention is improved, but the solution deteriorates rapidly over time reducing durability
Solution Approach 1:
The sealing gasket is designed as a durable, replaceable component integrated into the base structure, replacing the short-lived sealant. The gasket can be easily replaced if needed, providing long-term sealing durability without the rapid deterioration issues of conventional sealants.
3Reliability
If sealant is applied to prevent air leaks at connection posts, then sealing performance is improved, but the process becomes more complex and time-consuming
Solution Approach 1:
The sealing function is combined with the base component, eliminating the need for separate sealant application steps. The base with integrated gasket is simply attached to the post, and the sealing occurs automatically through the gasket compression, simplifying the assembly process while maintaining sealing performance.
4Reliability
If conventional sealant is used for sealing, then air leak prevention is achieved, but the solution has negative environmental impact
Solution Approach 1:
The sealing gasket is designed as a durable, replaceable component that eliminates the need for conventional sealants with negative environmental impact. The gasket can be made from eco-friendly materials and replaced if needed, providing long-term sealing without the harmful effects of traditional sealant products.

AI summary
The invention relates to a module for an air handling unit, comprising at least one side surface formed by the assembly of several panels arranged next to one another, a connection post (12) between two adjacent panels, including two facing fins (122) for positioning the panels, and two bases (14) for attaching the post (12) to an upper surface and to a lower surface (2), respectively, of the module, these bases being mounted at the two ends of the post. Each base (14) comprises two facing strips (18) which carry, on the interior side of the module, a rectilinear sealing gasket (20) for sealing the space between the fins (122) of the post (12) and the upper surface or lower surface (2) of the module.
