Overhead Fan Misting Layout for Wider Quiet Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional misting systems have a limited cooling area due to the size and noise constraints of high-velocity fans or blowers used to direct water-bearing airflows, which are often bulky and loud, making them unsuitable for larger or more effective temperature reduction.
Innovation Solution
An overhead fan misting system with a housing unit and axial fan that directs airflow through a series of chutes with misting nozzles positioned above them, increasing the cooling area by enhancing airflow velocity and distribution without the need for large or noisy equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If high-velocity fans or blowers are used to direct water-bearing airflows, then the cooling area is increased, but the fans become large and bulky
Solution Approach 1:
The patent divides the housing into multiple sections with multiple apertures and corresponding misting nozzles. The airflow is segmented into multiple streams rather than using a single large fan, allowing the cooling area to be extended without requiring a bulky high-velocity fan.
Solution Approach 2:
The patent uses multiple apertures arranged in a pattern on the housing, distributing the cooling function across multiple spatial dimensions. This allows the cooling area to be expanded in multiple directions simultaneously without increasing the size of individual fan components.
2Area of stationary object
If high-velocity fans or blowers are used to direct water-bearing airflows, then the cooling area is increased, but the fans become noisy
Solution Approach 1:
By segmenting the airflow into multiple lower-velocity streams through multiple apertures and nozzles, the system reduces the noise generated by each individual airflow stream while maintaining an extended cooling area collectively.
Solution Approach 2:
The patent introduces misting nozzles as intermediary elements between the fan and the environment. These nozzles disperse the airflow into fine mist streams, reducing the velocity and noise of the airflows while extending the cooling area through the mist distribution.
3Area of stationary object
If the size and speed of fans/blowers are increased to expand cooling area, then the cooling area is increased, but the system becomes too noisy to converse around
Solution Approach 1:
The system segments the cooling function across multiple low-velocity airflow streams instead of using a single high-velocity stream. This segmentation reduces the noise level to conversational thresholds while maintaining an extended cooling area through the distributed aperture and nozzle arrangement.
Solution Approach 2:
The patent changes the parameters of the airflow system by using multiple apertures with lower individual velocities rather than a single high-velocity stream. This parameter change reduces the noise generation while extending the cooling area through the distributed pattern of apertures and nozzles.
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 system effectively extends the cooling area by using low-pressure, high-flow axial fans in conjunction with strategically positioned misting nozzles and channels, providing quieter and more efficient cooling without the bulkiness and noise issues of traditional high-velocity systems.
Implementation Method 1
an axial fan that directs airflow through a series of chutes
Implementation Method 2
When water molecules evaporate into the air, the water changes from a liquid to a gas state. A certain amount of energy or heat is needed to assist this process of changing water from a liquid to a gas, which is automatically drawn from the surrounding air, thus lowering the ambient temperature around the misted area.
Implementation Method 3
The openings and/or nozzles may be used so that the water flowing through the tubing may be dispersed in the form of a mist.
