Ceiling Air Conditioner Partition Air Guide to Prevent Air Returning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ceiling-type air conditioners face issues with air flow control at corner portions and performance degradation due to re-absorption of weakly spreading flows at discharge ports, leading to air returning phenomena and reduced performance.
Innovation Solution
An air guide with parallel partitions and a curved arc-shaped connection is inserted into the discharge port, partitioning the inner space of the discharge panel to prevent air from being re-intaken and maintain maximum air volume discharge, while being detachable and easily manufacturable and mountable, and capable of detecting indoor temperature to reduce operation stoppages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a ring-shaped integrated discharge port is used to discharge air in all directions, then air discharge coverage is improved, but air flow control at corner portions deteriorates and air returning phenomenon occurs
Solution Approach 1:
The air guide divides the ring-shaped discharge port into multiple segments using partition walls. Each partition wall creates a separate discharge region that can control air flow independently, preventing air returning phenomenon at corner portions while maintaining overall 360-degree coverage.
Solution Approach 2:
The air guide acts as an intermediary component installed within the discharge port. It includes partition walls and guide surfaces that mediate the air flow between the blowing passages and the room, directing air away from corner portions where returning occurs while preserving the ring-shaped discharge pattern.
2Productivity
If the air guide is installed to prevent air returning, then air flow performance is improved, but device complexity increases
Solution Approach 1:
The air guide includes a rotatable curved portion that can change orientation to adjust air flow patterns. This dynamic element allows the system to adapt between different discharge modes (horizontal for cooling, vertical for heating) without requiring multiple fixed structures, managing complexity through controlled mobility.
Solution Approach 2:
The air guide serves multiple functions: it prevents air returning, directs horizontal air flow for cooling, directs vertical air flow for heating, and can be rotated to form swing air flows. This multi-functionality reduces the need for separate components for each function, thereby managing overall device complexity.
3Ease of operation
If a fixed air guide structure is used to control air flow, then air flow direction is improved, but ease of manufacture and installation deteriorates
Solution Approach 1:
The air guide is designed as a pre-assembled unit that can be installed into the discharge port without modifying the original air conditioner structure. The partition walls and curved portion are pre-positioned to achieve optimal air flow control, simplifying installation while maintaining effective air direction control.
Solution Approach 2:
The air guide uses simple geometric shapes (partition walls and curved surfaces) that provide sufficient air flow control without over-engineering. The partition walls extend only as needed to prevent air returning, and the curved portion provides adequate guidance without excessive complexity, balancing manufacturing ease with functional effectiveness.
