HVAC Damper Control Module with External Antenna for Retrofit Zoning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing HVAC systems face challenges in retrofitting zoning capabilities, particularly due to the diverse configurations of register vents and ducts, which complicates the installation of wireless dampers and control modules, leading to difficulties in accurately controlling environmental conditions within buildings.
Innovation Solution
A control module system that includes a damper assembly with a movable air damper, a control module housing secured to a register boot, and an antenna for wireless communication, allowing for remote control of damper positions and integration with existing HVAC systems, enabling precise control of air flow through ducts and vents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless dampers and control modules are installed in existing HVAC systems, then zoning capabilities are added, but installation difficulty increases due to variety of register vent and register boot configurations
Solution Approach 1:
The control module is designed with a universal mounting mechanism that can be installed on various register boot configurations. The housing includes mounting features that adapt to different register vent and register boot types, allowing the same control module to be universally installed across diverse existing HVAC systems without requiring custom modifications for each configuration.
2Adaptability or versatility
If control module is installed within register boot, then integration with existing HVAC system is achieved, but antenna positioning becomes challenging for wireless communication
Solution Approach 1:
The antenna is positioned in a third dimension by extending it through an opening in the register boot housing. This allows the antenna to protrude outward from the control module housing, providing adequate clearance for wireless signal transmission while maintaining the control module's integrated position within the register boot. The antenna extension resolves the spatial conflict between compact integration and effective wireless communication.
3Measurement precision
If existing HVAC system is retrofitted with zoning, then environmental control precision is improved, but system complexity increases
Solution Approach 1:
The control module integrates multiple functions into a single unit: the housing provides structural mounting, the controller manages damper positioning, the antenna enables wireless communication, and the opening facilitates both antenna extension and system integration. By combining these elements into one integrated control module, the system adds zoning precision without proportionally increasing overall system complexity.

AI summary
A control module configured to control operation of a damper assembly includes an air damper configured to be disposed within an air duct and movable between an open end position and a closed end position, the air duct providing conditioned air to a register boot proximate the air duct. The control module includes a control module housing that is securable to the register boot. A controller is disposed within the control module housing and is configured to generate damper position control signals, the controller providing the damper position control signals to the damper assembly via a control cable that operably couples the control module with the damper assembly. An antenna extends from the control module housing and is operably coupled to the controller, and is configured to extend through an opening formed within a wall of the register boot to be positioned exterior to the register boot.
