Air Conditioner Side Air Guide Design to Reduce Direct-Blow Discomfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air conditioners often cause discomfort due to direct air blowing, especially when human body temperature and ambient temperature are low, and this issue is more pronounced for senior people.
Innovation Solution
An air conditioner design featuring a side air guide member with air vents forming an air dispersion structure, including micropores, bubbles, louvers, and fan blades, which diverts airflow to the sides, reducing direct air-blowing discomfort and enhancing air guiding efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air conditioner blows air directly to people, then cooling effect is improved, but comfort is worsened due to wind sensation and cold air discomfort
Solution Approach 1:
The air outlet is divided into a front air outlet and side air outlets. The front air outlet directs air forward while the side air outlets direct air to the left and right sides, segmenting the airflow paths to reduce direct wind sensation on people while maintaining cooling effectiveness through distributed air delivery.
Solution Approach 2:
The patent introduces side air outlets that discharge air in lateral directions (left and right sides) in addition to the front direction. This adds dimensional diversity to the airflow pattern, transforming the single-direction direct blow into multi-directional distributed airflow, thereby reducing wind sensation while preserving cooling effect.
2Productivity
If air is blown directly to people, then air distribution is improved, but comfort is worsened especially for senior people when body temperature and ambient temperature are low
Solution Approach 1:
The air distribution system is segmented into multiple outlets (front and side outlets) that distribute air to different areas. This segmentation allows the air conditioner to maintain effective air distribution while reducing the intensity of direct cold air exposure on people, particularly benefiting senior people who are more sensitive to cold air.
Solution Approach 2:
Different regions of the air outlet structure are assigned different functions: the front air outlet provides general air distribution, while the side air outlets provide lateral air delivery. This local differentiation optimizes air distribution efficiency in different zones while minimizing cold air discomfort in occupied areas.
3Ease of operation
If side air guide member with air vents is added, then air guiding effect is improved and comfort is enhanced, but device complexity increases
Solution Approach 1:
The side air guide member integrates multiple functions: it serves as both a structural component of the air conditioner and as an air guiding device with built-in air vents. By merging the air guiding function into the existing side structure, the patent achieves improved air guiding effect without adding completely separate components, thereby limiting the increase in device complexity.
Solution Approach 2:
The side air guide member is designed as a multi-functional component that combines structural support with air guiding and air distribution functions. The air vents in the side air guide member enable it to perform both structural and airflow control functions, reducing the need for additional dedicated components and thus controlling device complexity.
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 solution provides a comfortable and efficient air distribution by reducing wind sensation while maintaining airflow intensity, improving cooling efficiency and energy efficiency by dispersing airflow laterally and controlling air discharge.
Implementation Method 1
the air vents in the side air guide member form an air dispersion structure. The air dispersion structure includes at least one of micropores, bubbles, louvers and fan blades
