Air Conditioner Swing Louver Reset Control for Position Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioners face issues with inconsistent swing louver positions due to manual adjustment, leading to non-uniform temperature distribution and potential interference, as well as noise and dust entry when louvers are closed abruptly.
Innovation Solution
Implementing a control method that resets swing louvers to fully open positions upon power-on and power-off, with timed closures and recalculations to ensure accurate positioning and synchronized movement, reducing interference and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If swing louvers are adjusted manually by users, then ease of operation is improved, but positioning accuracy deteriorates leading to inconsistent swing positions
Solution Approach 1:
The control system automatically detects and corrects louver position deviations without requiring manual user intervention. The processor monitors actual louver positions and sends correction commands to restore predetermined swing angles, enabling the system to self-correct positioning errors that would otherwise require manual adjustment.
Solution Approach 2:
The system implements a feedback mechanism where the processor continuously monitors the actual positions of swing louvers and compares them against predetermined positions. When deviations are detected, the system sends correction commands to adjust the louvers back to their correct positions, creating a closed-loop control system that maintains positioning accuracy.
2Measurement precision
If swing louvers are reset to fully open position, then positioning accuracy is improved, but loss of time increases due to reset operation
Solution Approach 1:
The system performs a preliminary reset of swing louvers to fully open positions before normal operation begins. This preliminary action ensures that all louvers start from a known reference position, eliminating any previous position deviations and establishing a consistent baseline for subsequent swing operations.
Solution Approach 2:
The reset operation is executed as a brief, intensive preliminary action that is completed quickly before normal operation commences. By concentrating the position correction into a focused reset phase rather than attempting continuous correction during operation, the system minimizes the time impact on overall performance.
3Productivity
If multiple swing louvers operate simultaneously, then productivity is improved, but harmful factors increase due to mutual interference and noise
Solution Approach 1:
The system divides the control of multiple swing louvers into independent, individually controllable units. Each louver can be positioned and adjusted separately by the processor, allowing precise control of each element rather than treating them as a single group. This segmentation enables coordinated operation that minimizes mutual interference while maintaining high productivity.

AI summary
The present application provides an air conditioner and a control method thereof. The air conditioner includes an indoor unit having a first air outlet. First swing louvers capable of controlling an opening-closing range of the first air outlet are disposed at the first air outlet. A controller including a memory and a processor is disposed in the indoor unit. The memory stores a computer program, and when the program is executed by the processor, a following step is able to be implemented: when the indoor unit is powered on, the first swing louvers operate to be in a fully open state to reset, and then operate to be in a fully closed state. The control method of the air conditioner is capable of executing the above program. A deviation between an actual swing and a required swing of swing louvers due to changes in initial positions of the swing louvers when the air conditioner is turned on is avoided.
