HVAC Return Air Intake Manager for Thermal Stratification Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
HVAC systems face inefficiencies due to stratified air temperatures, leading to increased energy consumption, operational costs, and decreased comfort, as existing methods do not optimally manage air intake and return pathways, particularly in heating and cooling modes.
Innovation Solution
An air intake manager apparatus with multiple inlets and an adjustable outlet that can be positioned to engage with return air vents, allowing for selective intake of warmest or coolest air based on operational mode, thereby optimizing air return to the HVAC system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If air return vents are placed at fixed locations without optimization, then the HVAC system can operate with simple installation, but the system experiences stratified air temperatures leading to increased energy consumption and decreased efficiency
Solution Approach 1:
The air return vent system is made dynamically adjustable through the air intake manager, which can be positioned at different heights and orientations to optimize air intake based on thermal stratification patterns. This dynamic adjustment allows the system to adapt to varying temperature distributions in the space, improving efficiency while managing energy consumption.
Solution Approach 2:
The invention changes the physical parameters of the air return system by introducing adjustable height and angle positioning capabilities. The air intake manager can be installed at different vertical positions and angles to intercept air at optimal temperatures, thereby changing the thermal characteristics of the returned air and improving overall system efficiency.
2Loss of time
If air delivery and return vents are placed without optimal positioning, then installation is simpler, but the HVAC system cannot reach desired temperatures quickly and experiences over-cooling and over-heating
Solution Approach 1:
The air intake manager provides dynamic positioning capabilities that allow optimization of air intake locations without requiring complex permanent installations. The adjustable design enables quick adaptation to different spatial configurations and thermal patterns.
Solution Approach 2:
The air return system is segmented into multiple adjustable components rather than a single fixed vent. This segmentation allows independent optimization of different air intake points, enabling faster temperature regulation while maintaining installation simplicity.
3Productivity
If return air vents are positioned without considering heating vs. cooling mode differences, then the system structure remains simple, but optimal operating efficiency is not achieved
Solution Approach 1:
The air intake manager is designed as a universal component that can serve both heating and cooling modes effectively. The same adjustable structure can be positioned to optimize for either mode, eliminating the need for separate vent configurations for each mode while maintaining optimal efficiency.
