Air Supply Device with Tornado-Like Vortex Flow for Temperature Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air supply devices often blow air into rooms that is too cold or too hot, and they fail to create well-defined vortex currents, leading to uncomfortable air flow and temperature differences, as well as high air velocity causing turbulence.
Innovation Solution
The air supply device features a casing with pocket portions and obliquely directed air nozzles that create a tornado-like air flow, mixing inlet air with room air and reducing static pressure to draw ambient air in, resulting in a stable and comfortable air flow with reduced temperature differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air is blown directly into the room through conventional air supply devices, then air supply function is achieved, but the air temperature differs significantly from room temperature causing discomfort
Solution Approach 1:
The patent applies preliminary action by creating tornado-like air flow and mixing inlet air with room air before the air is supplied to the room. The feed openings are configured to generate rotational flow that draws room air into the casing interior, pre-mixing the temperatures before discharge, thus avoiding the discomfort of direct cold or hot air blowing.
2Productivity
If high air velocity is used in air supply devices, then air flow efficiency is improved, but turbulence and discomfort to persons in the room increase
Solution Approach 1:
The patent applies dynamics by creating a tornado-like rotational air flow instead of direct linear flow. The feed openings are configured to generate swirling motion that maintains steady air flow while reducing turbulence. The rotational flow pattern naturally reduces velocity fluctuations and creates a more comfortable environment while maintaining effective air supply.
3Productivity
If conventional air supply devices are used, then air supply function is achieved, but no well-defined vortex currents are created reducing air intake efficiency
Solution Approach 1:
The patent applies spheroidality by creating tornado-like rotational air flow with well-defined vortex currents. The feed openings are configured to generate swirling motion that forms stable vortex structures within the casing. This curved rotational flow pattern enhances air intake efficiency by creating low-pressure regions that draw in ambient air, while maintaining stable and well-defined vortex structures.
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
This design achieves a comfortable room climate by mixing inlet air with room air, reducing temperature differences and air velocity, and creating a stable, non-disturbing air flow, even when the inlet air is significantly colder or warmer than the room temperature.
Implementation Method 1
cause a tornado-like air flow in each pocket portion, whereby the air circulating in the tornado-like air flow interacts with air from the room
Implementation Method 2
Because of the tornado-like air flow, there will be a drop in static pressure adjacent to such circulating air, which will draw ambient air into interior of the casing

AI summary
An air supply device for blowing air into a room is disclosed. The device has a casing (2) with two opposite, first and second side walls (21, 22) and a third wall there between, provided with a supply air opening (4). In the interior of the casing, there is an air feed tube (3) provided with feed openings (31-34) arranged so as to bring inlet air towards two pocket portions (25) located on each side of the supply air opening (4). The inlet air will circulate in a tornado-like air flow in the pocket portions and interact with the air from the room before it flows out through the supply air opening (4) into the room. Hereby the room climate will be improved.
