Ceiling-Embedded Air Outlet Layout for Wider Room Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ceiling-embedded air conditioners have difficulty uniformly air-conditioning a room due to fixed air blowing openings that restrict airflow direction, limiting their ability to condition the entire space effectively.
Innovation Solution
Incorporating a fixed air blowing portion with movable air blowing portions that rotate within a predetermined angle range, allowing conditioned air to be blown out over a wider area along the panel surface, thereby enhancing airflow distribution across the room.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed air blowing opening is used, then the structure is simple and reliable, but the air blowing range is limited to one direction making it difficult to air-condition the entire room
Solution Approach 1:
The air blowing structure is divided into a fixed air blowing portion and multiple movable air blowing portions. Each movable air blowing portion can independently rotate to change its blowing direction, allowing the system to cover a wider air conditioning range while maintaining a relatively simple overall structure.
Solution Approach 2:
The movable air blowing portions are designed to rotate between different positions (first position facing a specific side, second position facing another adjacent side). This dynamic capability enables the air conditioner to adaptively adjust airflow directions to cover different areas of the room, resolving the contradiction between fixed structure simplicity and air blowing versatility.
2Adaptability or versatility
If airflow direction vanes are provided at the air blowing opening, then airflow direction can be adjusted, but the air blowing opening itself remains fixed limiting the air blowing range to one direction
Solution Approach 1:
Instead of only adjusting airflow direction within a fixed opening plane using vanes, the invention adds a rotational dimension to the air blowing portions themselves. This allows the air blowing openings to face different sides of the room, expanding the air conditioning coverage from a single directional plane to multiple spatial dimensions.
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 enables uniform air conditioning by allowing conditioned air to be blown out in multiple directions, improving airflow coverage and room conditioning efficiency.
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

AI summary
In order to quickly condition a room by blowing conditioned air from an air blowing opening over a wide range, a fixed air blowing portion 75 is disposed at a central portion in a raised portion 740 in which a part of a decorative panel 70 is raised toward the air conditioning room. Movable air blowing portions 77 are disposed on both sides thereof. The movable air blowing portion 77 is rotatable within a predetermined angle range around an axis orthogonal to the panel surface of the decorative panel 70 or to the ceiling surface, while air blowing openings 754 and 783 are formed on each side surface of the fixed air blowing portion 75 and the movable air blowing portion 77. As a result, the conditioned air is blown out in a wide range in the horizontal direction from the air blowing opening 783 as the movable air blowing portion 77 rotates.
