Ceiling Cassette Airflow Flap Layout for Draft-Free Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ceiling-embedded type air conditioners with visible main and sub-flaps mar the appearance while attempting to control air direction and speed, and they often cause unpleasant cold drafts during cooling operations.
Innovation Solution
The air conditioner features a main flap and a sub-flap with a second guide part that rotates to change air direction, and a heat insulating member is used to prevent dew condensation, allowing air to flow in a desired direction without compromising design aesthetics and reducing cold draft discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If main flap and sub-flap are installed to control air direction, then air flow control is improved, but appearance is marred due to visible flaps and parting lines
Solution Approach 1:
The sub-flap is nested within the main flap structure, where the sub-flap is positioned inside the contour of the main flap. This nesting arrangement allows both flaps to function for air direction control while the sub-flap remains hidden within the main flap's visual boundary, eliminating visible parting lines and maintaining a clean appearance.
2Productivity
If flaps are designed to blow air to feet during heating, then heating efficiency is improved, but cold drafts occur during cooling operations
Solution Approach 1:
The flaps are designed with dynamic adjustability, allowing the main flap and sub-flap to rotate and change orientation based on operational mode. During heating, the flaps direct air downward to feet for efficient heating. During cooling, the flaps automatically adjust to lateral positions to direct air horizontally, preventing cold drafts from reaching occupants directly.
3Adaptability or versatility
If second guide part rotates to change air direction, then air direction flexibility is improved, but device complexity increases
Solution Approach 1:
The second guide part is merged with the sub-flap structure, combining the guiding function into the existing flap assembly. This integration allows the sub-flap to serve dual purposes: controlling air direction through rotation and guiding air flow through the merged second guide part, thereby achieving air direction flexibility without proportionally increasing device complexity.

AI summary
Disclosed herein is an air conditioner capable of guiding air in a desired direction with an adjusted speed without marring the appearance to solve the above-described problems. An air conditioner comprising a ceiling-embedded type indoor unit configured to discharge air into an indoor room through an air outlet simultaneously sucking indoor air through an air inlet, wherein a air conditioner comprises, a main flap configured to guide a direction of air discharged from a air outlet in a preset direction, and a sub-flap configured to guide the direction of air between the main flap and the sub-flap in the preset direction, wherein a length of a main flap in a direction where air flows is longer than that of the sub-flap in the direction where air flows.
