Ceiling Cassette Air Outlet With Rotatable Louvers for Uniform Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ceiling-embedded air conditioners have difficulty uniformly air-conditioning a room due to fixed air blowing openings, which restrict airflow direction and range.
Innovation Solution
A ceiling-embedded air conditioner design featuring a box-shaped main unit with a decorative panel that includes a fixed air blowing portion and movable air blowing portions, allowing the second air blowing opening to rotate within a predetermined angle range, enabling airflow in multiple directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed air blowing opening is used in the decorative panel, then the structure is simple and easy to manufacture, but the air blowing range is limited and the room cannot be uniformly air-conditioned
Solution Approach 1:
The patent applies the dynamics principle by making the air blowing portions rotatable around the air blowing opening. The movable air blowing portions can rotate within a predetermined angle range to change the air blowing direction, transforming a static structure into a dynamic one that adapts to different air conditioning needs while maintaining uniform temperature distribution throughout the room
2Adaptability or versatility
If airflow direction vanes are provided at the air blowing opening, then the airflow direction can be adjusted, but the air blowing range remains limited to one direction that the air blowing opening faces
Solution Approach 1:
Instead of using fixed airflow direction vanes that only adjust within a limited range, the patent employs rotatable movable air blowing portions that can change the orientation of the air blowing opening itself. This dynamic approach allows the air blowing direction to be adjusted to face different sides of the decorative panel, providing comprehensive room coverage without the complexity of multiple vane mechanisms
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 allows for uniform air conditioning of a room by directing conditioned air over a wide range, improving airflow coverage and room temperature consistency.
Implementation Method 1
The air sucked from the suction opening can exchange heat with the refrigerant in the heat exchanger
Implementation Method 2
a blowing fan formed of a sirocco fan surrounded by a fan casing in the center of the heat exchanger
