Ceiling Air Conditioner Air Guide to Prevent Corner Re-Intake
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ceiling-type air conditioners with circular designs face issues with air flow control at discharge ports, leading to air being re-absorbed at corners, which degrades performance and results in a returning air phenomenon.
Innovation Solution
An air guide with parallel partitions and a curved portion is integrated into the discharge panel, allowing for detachable installation and enhancing air flow directionality, preventing air re-intake and maintaining maximum air volume discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a ring-shaped integrated discharge port is used for 360° air discharge, then air can be evenly discharged in all directions, but air flow control at corner portions is not possible and air re-intake occurs at corners
Solution Approach 1:
The discharge port is divided into multiple segments: a main discharge port for primary air ejection and corner discharge ports for directional control. The air guide further segments the airflow into multiple streams that can be independently directed, allowing precise control at corner portions while maintaining overall 360° discharge capability.
Solution Approach 2:
An air guide structure is introduced as an intermediary component between the blowing passages and the discharge port. This air guide includes partition walls that redirect airflow away from corner regions, preventing re-intake while maintaining discharge performance. The air guide acts as a mediator that resolves the conflict between omnidirectional discharge and corner flow control.
2Shape
If a circular air conditioner design is used, then aesthetic appearance is improved, but air re-intake at corners degrades heating performance
Solution Approach 1:
The air guide structure applies local quality modification by introducing partition walls at specific corner regions while maintaining the overall circular design. The partition walls are strategically positioned to block re-intake paths only at corner portions, leaving the main discharge areas unaffected. This localized intervention preserves heating performance without compromising the aesthetic circular appearance.
3Reliability
If an air guide with multiple partitions is installed, then air flow directionality is improved and re-intake is prevented, but device complexity increases
Solution Approach 1:
The air guide structure incorporates movable or adjustable partition walls that can be dynamically positioned to optimize airflow patterns. The partition walls are designed to be flexible or rotatable, allowing the system to adapt to different operating conditions (heating/cooling modes) and room configurations, thereby improving airflow directionality control while managing structural complexity through dynamic adaptability.
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 air guide effectively prevents air re-intake, maintains discharge air volume, and improves air flow directionality for enhanced cooling and heating performance, reducing operation stoppages and user discomfort.
Implementation Method 1
the air guide includes at least two partitions formed to be parallel to a radial direction of the opening and partitioning the inner space of the discharge panel in a circumferential direction; and a curved portion connecting the at least two partitions and having an arc shape

AI summary
An air guide for a ceiling-type air conditioner is applied to the ceiling-type air conditioner comprising: an indoor unit having a heat exchanger and a blower embedded therein, and having a plurality of blowing passages for discharging, to the outside, air which has passed through the heat exchanger; a plurality of inlets for receiving the air discharged through the plurality of blowing passages; and a discharge panel having an inner space, of which at least a portion communicates with the plurality of inlets, and a ring or arc-shaped opening for discharging, into a room, air which has flowed into the inner space. The air guide includes: at least two partition parts formed in parallel to the radial direction of the opening, and dividing the inner space in the circumferential direction; and a curved part connecting the at least two partition parts, and formed in an arc shape, and is detachably inserted into the inside of the opening from the outside of the opening.
