Circular Air Supply Structure for Uniform Vertical AC Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vertical air-conditioners suffer from low indoor air circulation and non-uniform air distribution, leading to discomfort, as they primarily supply heat-exchanged air without additional air supply apparatuses, resulting in limited application scope and assembly flexibility.
Innovation Solution
A vertical air-conditioner air supply apparatus comprising three circular air guiding bodies with sequential through-ducts and airflow distribution assemblies that mix non-heat-exchanged air with heat-exchanged air, ensuring uniform air distribution and increased intake volume, featuring adjustable structures for enhanced user comfort and broader application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional vertical air-conditioner supplies only heat-exchanged air directly from the heat exchanger to the air outlet, then the structure is simple, but the indoor air circulation is slow and the air flow rate is low
Solution Approach 1:
The air supply apparatus is divided into multiple independent components: a cover body with through-duct, circular deflectors with air outlet ducts, and an airflow distribution assembly. This segmentation allows each component to perform its specific function while maintaining overall system efficiency and enabling flexible assembly and disassembly.
2Ease of operation
If all supplied air is heat-exchanged air, then the air supply structure is simple, but the supplied air is not mild enough and users feel uncomfortable
Solution Approach 1:
The apparatus merges heat-exchanged air from the heat exchanger with non-heat-exchanged air from the indoor environment through the through-duct and circular air outlet ducts. This combination produces milder air that improves user comfort while avoiding the discomfort of direct cold air blowing.
3Manufacturing precision
If the fan supplies air from bottom to top, then the air supply method is simple, but the heat-exchanged air is not uniformly distributed in the circumferential direction
Solution Approach 1:
The airflow distribution assembly includes multiple circular deflectors positioned at different locations around the through-duct, with each deflector having air outlet ducts oriented in different directions. This local differentiation ensures uniform air distribution in all circumferential directions, addressing the non-uniformity caused by bottom-to-top air supply.
4Adaptability or versatility
If the circular deflector and circular air outlet duct are both formed on one circular cover body, then the structure is integrated, but it is not convenient to flexibly select and control the structure
Solution Approach 1:
The cover body, circular deflectors, and airflow distribution assembly are designed as separate components that can be independently manufactured, selected, and assembled. This segmentation provides flexibility in structure selection and control while simplifying assembly and maintenance operations.

AI summary
A vertical air-conditioner and a vertical air-conditioner air supply apparatus (1) are disclosed. The vertical air-conditioner air supply apparatus (1) includes three circular air guiding bodies (11, 12, 13) that are hollow and have front and rear openings. Each of the circular air guiding bodies (11, 12, 13) is a single component. The three circular air guiding bodies (11, 12, 13) are arranged sequentially from front to rear, and a through-duct that runs through from front to rear is formed in the middle. An air inlet (122) of a rear-end circular air guiding body (12) located at the rear end forms a non-heat-exchanged air inlet of the air supply apparatus. An air outlet (111) of a front-end circular air guiding body (11) located at the front end forms a mixed air outlet. A circular heat-exchanged air duct (14, 15) is formed between two adjacent circular air guiding bodies (11, 12, 13). An airflow distribution assembly (16) for circumferentially distributing heat-exchanged air is disposed in at least one of the circular heat-exchanged air ducts (14, 15). In a vertical air-conditioner that uses the air supply apparatus (1), the air supply is uniform, the air flow of the air supply is large, and the temperature of the air supply is comfortable.
