Air Diffuser with Low Flow Adapter Nozzles for Enhanced Dispersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air diffusers fail to provide significant dispersion of conditioned air when the air flow through ducts is at low rates or volumes, leading to inadequate heating, cooling, or ventilation in interior spaces.
Innovation Solution
An enhanced air diffuser design featuring a low flow adapter with extruded nozzles angled relative to the horizontal plane, which increases air velocity and induction, and a diffusion plate to enhance the dispersion of conditioned air into interior spaces, even at low flow rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional air diffusers are used, then the structure is simple and easy to manufacture, but the dispersion of conditioned air is insufficient at low flow rates
Solution Approach 1:
The air diffuser is divided into multiple functional components: a mounting plate with a central opening, a low flow adapter with multiple nozzles, and a diffusion plate. This segmentation allows each component to perform a specific function - the nozzles accelerate air while the diffusion plate spreads it - thereby improving air dispersion effectiveness at low flow rates without significantly complicating manufacturing
Solution Approach 2:
The low flow adapter acts as an intermediary component between the duct opening and the diffusion plate. It includes multiple nozzles that accelerate the conditioned air flow before it reaches the diffusion plate, which then disperses the air throughout the space. This intermediary mechanism enables effective air distribution at low flow rates where conventional diffusers fail
2Loss of energy
If low flow rates are used, then energy consumption is reduced, but air velocity and dispersion are insufficient
Solution Approach 1:
The low flow adapter changes the flow parameters by accelerating the air through multiple angled nozzles. Even though the overall flow rate remains low (reducing energy consumption), the air velocity is increased locally as it passes through the nozzles. This parameter change enables effective dispersion without requiring high energy input
Solution Approach 2:
The system dynamically adapts to low flow conditions by using the low flow adapter to concentrate and accelerate the limited air supply. The angled nozzles create dynamic air patterns that enhance dispersion effectiveness, allowing the system to maintain performance at varying flow rates including low energy consumption scenarios
