Solution Overview
Problem
HVAC systems face inefficiencies in airflow distribution, leading to hot and cold spots and increased energy costs due to insufficient airflow rates in ducts.
Innovation Solution
A Venturi-like tube apparatus is mounted inside HVAC pipes, featuring an entrance cone, throat, and exit cone, which accelerates airflow through the Venturi effect, creating a cyclonic flow pattern that enhances airflow velocity and prevents hot and cold spots by ensuring consistent air distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If airflow rate is increased to prevent hot and cold spots, then air distribution uniformity is improved, but energy consumption increases
Solution Approach 1:
The patent changes the physical parameters of the duct system by introducing variable cross-sectional area sections (tapered sections) that modify airflow characteristics. This allows achieving better temperature distribution uniformity through geometric parameter optimization rather than simply increasing airflow rate, thus avoiding proportional energy consumption increase.
Solution Approach 2:
The patent applies different cross-sectional area characteristics at different locations along the duct - tapered sections in specific regions and constant sections in others. This local differentiation optimizes airflow distribution in problem areas without requiring system-wide airflow increase, reducing overall energy consumption while improving local temperature uniformity.
2Speed
If duct cross-section is reduced to increase flow velocity, then airflow velocity is improved, but pressure loss increases
Solution Approach 1:
The patent divides the duct into multiple segments with different cross-sectional characteristics - tapered sections for velocity enhancement and constant sections for pressure recovery. This segmentation allows velocity increases only where needed while maintaining pressure in other sections, reducing overall pressure loss compared to continuous reduction.
Solution Approach 2:
The patent uses tapered (curved) cross-sectional transitions instead of abrupt changes. The gradual curvature of the tapered sections reduces flow separation and turbulence, minimizing pressure losses while still achieving the desired velocity increase through the transition zones.

AI summary
Disclosed herein is an apparatus for facilitating improving flow of fluid in a duct, in accordance with some embodiments. The apparatus comprises a first portion, a third portion, and a second portion. Further, continuously attaching an inlet edge using an attachment member and an outlet edge defines an interior space. Further, a first amount of the fluid entering a first interior space through an inlet opening flows to a third interior space with a first velocity and a first direction. Further, portions of a second amount of the fluid flows into the third interior space through second openings with a second velocity and second directions. Further, the fluid flows from the third interior space with a third velocity and a cyclonic flow pattern for exiting through an outlet opening based on interacting of the portions of the second amount of the fluid with the first amount of the fluid.
