Air Supply Assembly for Uniform Circumferential Air Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air-conditioners supply air with low flow rate and non-uniform distribution, leading to uncomfortable indoor air circulation and user experience, especially in cooling mode, due to direct blowing of heat-exchanged air without additional distribution mechanisms.
Innovation Solution
An air-conditioner air supply apparatus with an airflow distribution assembly is introduced, featuring a non-annular cover body, deflectors, and bilaterally symmetric airflow distribution plates to distribute heat-exchanged air uniformly in the circumferential direction, enhancing air intake volume and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If heat-exchanged air is directly blown out from the air outlet without additional air supply apparatus, then the device complexity is low, but the air flow rate is low and indoor air circulation is slow
Solution Approach 1:
The air supply apparatus is nested within the air conditioner body, with the cover body, heat-exchanged air duct, and airflow distribution assembly integrated into the existing internal air duct structure. The airflow distribution assembly is positioned within the heat-exchanged air duct, creating a compact nested arrangement that increases air flow rate without significantly increasing overall device complexity.
2Manufacturing precision
If heat-exchanged air is directly blown out without additional air supply apparatus, then the device complexity is low, but the air supply uniformity in circumferential direction is poor
Solution Approach 1:
The airflow distribution assembly segments the heat-exchanged air flow into multiple directional streams using several airflow distribution plates arranged at different angles. These plates divide the single air flow into multiple smaller flows that are distributed more uniformly in the circumferential direction, improving air supply uniformity without requiring a completely new system.
Solution Approach 2:
The airflow distribution plates are arranged in three-dimensional space within the heat-exchanged air duct, extending in different directions to distribute air not only radially but also axially. This multi-dimensional arrangement of distribution plates creates more uniform circumferential air supply by utilizing spatial dimensions rather than simply increasing duct cross-sectional area.
3Ease of operation
If all supplied air is heat-exchanged air, then the device complexity is low, but the supplied air is not mild enough and user comfort is reduced
Solution Approach 1:
The airflow distribution assembly acts as an intermediary between the heat-exchanged air source and the air outlet. By introducing this intermediate distribution mechanism, the harsh direct heat-exchanged air flow is transformed into a more uniform and milder air supply that is comfortable for users, without requiring mixing with external air or complex temperature control systems.
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 solution increases air intake volume, accelerates indoor air circulation, and provides a more uniform and comfortable air supply by mixing heat-exchanged and non-heat-exchanged air, improving user experience and air distribution uniformity.

AI summary
An air-conditioner air supply apparatus includes a non-annular cover body (101). A through-duct running through the non-annular cover body (101) is formed in the middle of the non-annular cover body (101). The non-annular cover body (101) has a front opening and a rear opening. The front opening forms a mixed air outlet (1016). The rear opening forms a non-heat-exchanged air inlet (1017). A non-annular main heat-exchanged air duct (1011) communicating an internal air duct (15) of an air-conditioner having the air-conditioner air supply apparatus with the through-duct is formed on a wall of the non-annular cover body (101). An airflow distribution assembly (18) for circumferentially distributing heat-exchanged air that enters the main heat-exchanged air duct (1011) from a heat exchanger of the air-conditioner is disposed in the non-annular main heat-exchanged air duct (1011). Also disclosed is an air-conditioner having the air-conditioner air supply apparatus.
