Control method and air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioner control technologies inadequately address abnormal weather conditions such as rain, snow, sand, and dust, leading to malfunctions and reduced reliability of outdoor units, which can accelerate aging and increase maintenance costs.
Innovation Solution
A control method that obtains real-time abnormal weather information to determine optimal operating parameters for the draught fan of the outdoor unit, allowing it to adjust its operation according to specific weather conditions, thereby reducing the adverse impact of weather on the unit and preventing failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the outdoor unit only monitors outdoor environment temperature to adjust capacity, then the control system remains simple, but the protection measure against abnormal weather conditions is insufficient
Solution Approach 1:
The system obtains abnormal weather information in advance through weather information acquisition modules (including web crawlers and weather APIs) before the weather actually affects the outdoor unit. This allows the control system to prepare appropriate operating parameters preemptively, enhancing protection without requiring complex real-time decision-making infrastructure
Solution Approach 2:
The control method segments different abnormal weather conditions (rain, snow, sand and dust, storm wind, hail) into distinct categories, each with predefined operating parameters. This segmentation allows the system to handle multiple weather types through a structured approach, balancing comprehensiveness with manageable complexity
2Reliability
If the draught fan operates without weather-based parameter adjustment, then the operation remains simple, but the adverse impact of weather on the outdoor unit increases
Solution Approach 1:
The control system automatically obtains weather information, determines the current weather condition, selects appropriate operating parameters, and adjusts the draught fan without user intervention. The system serves itself by integrating weather information acquisition, condition judgment, and parameter adjustment into an autonomous control loop, maintaining ease of operation while enhancing reliability
Solution Approach 2:
The system changes the operating parameters of the draught fan based on weather conditions, including rotation speed, operating cycle, and airflow direction. These parameter adjustments are automatically determined by the control system based on the obtained weather information, allowing the fan to adapt to different weather conditions without complex manual operation
3Measurement precision
If real-time weather information is obtained and processed, then the control accuracy improves, but the information processing time and system complexity increase
Solution Approach 1:
The system performs preliminary judgment of weather conditions by comparing obtained weather information against predefined weather condition criteria. This preliminary assessment quickly identifies the current weather category, allowing the system to proceed directly to parameter selection without extensive analysis, thus reducing processing time while maintaining accuracy
Solution Approach 2:
The system uses predefined operating parameter sets for different weather conditions, essentially copying proven effective parameters from historical data or design specifications. Instead of calculating optimal parameters in real-time, the system selects from pre-established parameter templates, significantly reducing computation time while maintaining control accuracy
