Columnar Airflow Stator Vanes for Ceiling Air Destratification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional heating, ventilation, and air conditioning systems suffer from air temperature stratification, leading to inefficient heating and cooling costs due to the dispersion of air, particularly in large spaces with high ceilings, and existing solutions like ceiling fans and vertical tube fans are either ineffective or aesthetically unpleasing.
Innovation Solution
A columnar air moving device with modular stator vanes that convert rotary airflow into laminar and axial airflow, minimizing lateral dispersion and requiring no physical tube, featuring a housing with a rotary fan and stator vane assembly that can be easily assembled and disassembled for configuration adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a ceiling fan is used to move air, then air circulation is improved, but the air disperses laterally and fails to maintain a columnar pattern from ceiling to floor
Solution Approach 1:
The air moving device is divided into multiple functional segments: an impeller section for generating airflow, a stator vane section for converting rotary flow to axial flow, and a housing structure for guiding the air column. This segmentation allows each component to perform its specific function optimally, maintaining the columnar pattern while ensuring effective air circulation.
Solution Approach 2:
Stator vanes are introduced as an intermediary element between the impeller and the surrounding environment. These stator vanes convert the rotary airflow generated by the impeller into a laminar axial flow, acting as a mediator that transforms the airflow characteristics to maintain a stable columnar pattern from ceiling to floor.
2Productivity
If a fan connected to a vertical tube is used, then air de-stratification is achieved, but the device interferes with floorspace use and is aesthetically unpleasing
Solution Approach 1:
The physical tube that previously extended from ceiling to floor is extracted and replaced by a compact housing structure containing the impeller and stator vanes. The housing is mounted near the ceiling and generates a columnar airflow pattern that extends downward without requiring a physical tube, thereby eliminating the interference with floorspace while maintaining air de-stratification effectiveness.
3Productivity
If the impeller blades are positioned close to the stator vanes, then airflow conversion is improved, but manufacturing complexity increases due to molding difficulties
Solution Approach 1:
The housing is divided into multiple separable components including the impeller section, stator vane section, and end caps. This segmentation allows each component to be manufactured independently using standard molding techniques, avoiding the complexity of molding a single integrated structure with tight tolerances, while still enabling precise positioning of the impeller blades relative to the stator vanes for optimal airflow conversion.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively destratifies air by maintaining a columnar airflow pattern from ceiling to floor with minimal dispersion, reducing energy loss and noise, while being aesthetically pleasing and requiring low power consumption.
Implementation Method 1
modular stator vanes, which direct air in an axial direction away from the device
Implementation Method 2
converting the rotary component of the air flow into laminar and axial air flow in the housing
Implementation Method 3
A rotary fan is mounted in the housing near the air inlet and having an impeller with a diameter and a plurality of blades that produce an air flow with rotary and axial air flow components
Implementation Method 4
A device with a rotary fan that minimizes the rotary component of the air flow while maximizing the axial air flow quantity and velocity can provide a column of air that flows from a high ceiling to a floor in a columnar pattern with minimal lateral dispersion

AI summary
A columnar air moving device can comprise separately formed modular stator vanes in a stator vane assembly. The stator vanes can be arranged in a radial pattern, and can direct air in an axial direction. The modular stator vanes, as well as other components of the stator vane assembly, can be replaced, adjusted, and/or removed from the columnar air moving device.
