Air conditioner and air conditioner control method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air conditioners have high energy consumption due to the need for continuous operation of compressors to maintain cooling, leading to inefficient energy use and increased costs.
Innovation Solution
An air conditioner system that includes a compressor, a room temperature detector, and an integrated controller capable of adjusting the compressor's operating frequency based on user-set target temperatures and power-saving commands, allowing for real-time adjustments to reduce energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the compressor operates continuously at high frequency to maintain cooling, then the cooling performance is improved, but the energy consumption increases
Solution Approach 1:
The patent applies dynamics by making the compressor's operating frequency variable rather than fixed. The integrated controller dynamically adjusts the operating frequency based on real-time temperature differences between the target and actual room temperatures, allowing the system to optimize between cooling performance and energy consumption according to actual conditions.
Solution Approach 2:
The patent changes the operating parameter (frequency) of the compressor based on the temperature difference. When the temperature difference is large, the compressor operates at higher frequency for rapid cooling; when the difference is small, it operates at lower frequency to save energy, thus resolving the contradiction between cooling performance and energy consumption.
2Speed
If the compressor operates at high frequency to meet cooling demand, then the cooling speed is improved, but the power consumption increases
Solution Approach 1:
The system dynamically adjusts the compressor's operating frequency based on the temperature difference. During initial cooling when the temperature difference is large, the compressor runs at high frequency for fast cooling. As the temperature approaches the target, the frequency is reduced, optimizing the balance between cooling speed and power consumption throughout the operation cycle.
Solution Approach 2:
The patent implements periodic adjustment of the compressor frequency based on monitoring the temperature difference at set intervals. The controller periodically evaluates whether the temperature difference warrants high-frequency operation or if lower frequency is sufficient, creating a rhythmic adjustment pattern that optimizes power consumption while maintaining cooling effectiveness.
