Plenum conversion kit for HVAC system and method of installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing HVAC systems face challenges in integrating new equipment with existing ductwork, requiring custom fabrication of metal plenums and transitions, which is time-consuming, costly, and demands specialized skills. Additionally, existing kits often lack necessary components for various sizes and configurations, and do not adequately address noise reduction and vibration dampening.
Innovation Solution
A comprehensive plenum conversion kit that includes pre-cut panels with noise-reducing cross breaks and dual hems, S-cleats for secure attachment to ductwork, and all necessary securing hardware and instructions. This kit is designed to be universally compatible with various HVAC systems, reducing the need for custom fabrication and minimizing labor costs and potential errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If custom fabrication of metal plenums and transitions is performed manually, then fit and configuration accuracy can be achieved, but installation time and labor costs increase significantly
Solution Approach 1:
The patent applies preliminary action by providing pre-cut panels with pre-formed hemmed edges and pre-configured attachment features. These panels are manufactured in advance with precise dimensions and built-in attachment mechanisms, eliminating the need for on-site measuring, cutting, and fabrication. This allows installers to simply assemble the pre-prepared components, dramatically reducing installation time while maintaining fit accuracy.
2Ease of operation
If complete all-in-one kit with all necessary components is provided, then installation convenience and speed improve, but kit complexity and initial cost increase
Solution Approach 1:
The patent applies merging by combining multiple separate components (panels, S-cleats, fasteners, and instructions) into a single integrated all-in-one kit. This consolidation ensures that all necessary elements for a complete installation are provided together, eliminating the need for technicians to source additional materials separately. The kit is designed as a unified system where components work together seamlessly, simplifying the installation process despite the multiple components included.
3Ease of manufacture
If standard panels without vibration dampening features are used, then manufacturing simplicity is maintained, but noise reduction and system durability are compromised
Solution Approach 1:
The patent applies local quality by incorporating cross breaks specifically at strategic locations on the panels where vibration and noise occur. These cross breaks create localized rigidities that dampen vibrations without requiring the entire panel structure to be complex. The hemmed edges also provide localized reinforcement and damping at the attachment points. This targeted approach reduces noise and vibration while keeping the overall manufacturing process relatively simple.

AI summary
A plenum conversion kit for enclosing an evaporator coil within a building's plenum is provided. The kit includes a flat panel, one or more S-cleats, duct tape, screws, and an angle bracket tailored for integrating an air conditioning evaporator coil during HVAC system upgrades or installations. This kit facilitates a seamless transition by allowing the evaporator coil to be installed within the plenum space of existing furnace systems without requiring extensive custom fabrication. The flat panel is designed with dimensions to accommodate common evaporator sizes and includes pre-measured fold lines and cuts to ensure accurate assembly. The primary advantage of this kit is its efficiency and convenience, significantly reducing installation time and material waste by providing all necessary components in one package. Additionally, the design of the kit promotes a stable and secure enclosure for the evaporator, enhancing system performance and durability.
