Ceiling Air Conditioner Vane Control for Uniform Natural Wind
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ceiling type air conditioners take longer to reach a desired indoor air conditioning environment and provide uneven temperature and airflow distribution, especially in natural wind mode, leading to a less pleasant user experience.
Innovation Solution
The method involves a ceiling type air conditioner with four discharge vanes that rotate through specific angle groups to guide airflow in different directions, mimicking natural wind patterns, with a controller managing the rotation angles and cycles to ensure rapid and uniform temperature and airflow distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rotation angular speed of vanes is reduced with periodic stop times to implement natural wind characteristics, then the natural wind effect is improved, but the time required to reach desired indoor air conditioning environment is excessively increased
Solution Approach 1:
The air conditioner divides the discharge airflow into four separate streams through four independently controllable discharge vanes positioned at different locations. Each vane can be controlled separately to create a distributed airflow pattern that simulates natural wind without requiring periodic stopping, thus maintaining both the natural wind effect and rapid cooling/heating performance
Solution Approach 2:
The discharge vanes are designed to rotate dynamically to different angles rather than being fixed or periodically stopped. The controller adjusts the rotation angles of the four discharge vanes in real-time to optimize airflow distribution, creating natural wind characteristics while continuously maintaining effective temperature control
2Device complexity
If single-direction discharge airflow is used to simplify the structure, then the device complexity is reduced, but the temperature distribution and airflow distribution in indoor space become uneven
Solution Approach 1:
The discharge system is segmented into four separate discharge vanes positioned at different locations around the air conditioner unit. Each vane directs airflow in a different direction, creating a multi-directional airflow pattern that ensures uniform temperature and airflow distribution throughout the indoor space without requiring complex mechanical structures
Solution Approach 2:
The four discharge vanes are positioned asymmetrically around the unit rather than in a simple linear arrangement. This asymmetric positioning allows each vane to cover different zones of the room, creating more effective and uniform airflow distribution compared to symmetric single-direction discharge
3Stability of the object's composition
If four discharge vanes with multiple rotation angles are implemented to improve airflow distribution, then the temperature distribution uniformity is improved, but the device complexity increases
Solution Approach 1:
The control system merges the control of four discharge vanes into a unified control architecture. The controller simultaneously manages all four vanes using a coordinated control strategy, reducing the overall system complexity compared to four independent control systems while maintaining the ability to achieve uniform airflow distribution
Solution Approach 2:
The controller is designed with multi-functionality to handle various operation modes (cooling, heating, natural wind mode) and automatically adjust the discharge vane angles accordingly. This universal control approach simplifies the device by using a single controller for multiple functions rather than separate controls for each mode
