Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air conditioner compressors consume a large amount of standby power due to continuous electric heating when in a standby state, leading to high energy consumption, as the outdoor environment's change trend cannot be predicted in advance.
Innovation Solution
A method and device that utilize a controller to monitor the shutdown duration of the air conditioner compressor, acquire weather forecast data, and generate a control strategy to start and stop electric heating based on temperature trend analysis, reducing unnecessary heating during non-ascending temperature periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electric heating belt of the compressor is always enabled during standby process to ensure reliability, then the compressor reliability is improved, but the standby power consumption increases significantly
Solution Approach 1:
The patent applies dynamics by transitioning the electric heating belt from a static always-on state to a dynamic controlled state. The controller adjusts the heating belt operation based on real-time temperature monitoring and weather forecast data, enabling the system to adapt its heating behavior to actual environmental conditions rather than maintaining a fixed operational mode
Solution Approach 2:
The patent implements preliminary action by acquiring weather forecast data in advance and analyzing temperature trends before making heating decisions. The controller uses predicted temperature changes to proactively determine when heating is necessary, allowing the system to prepare and respond to upcoming temperature drops rather than reacting after they occur
Solution Approach 3:
The patent employs feedback mechanisms by continuously monitoring the ambient temperature around the compressor and comparing it against threshold values and predicted temperature trends. This closed-loop feedback system allows the controller to adjust the heating belt operation based on actual temperature conditions and forecasted changes, creating a responsive control system that balances reliability with energy efficiency
2Object-affected harmful factors
If the electric heating belt operates continuously to protect the compressor, then the compressor protection is improved, but the energy consumption during standby increases
Solution Approach 1:
The patent applies parameter changes by modifying the operational parameters of the electric heating belt based on temperature conditions. Instead of maintaining constant operation, the system adjusts the heating belt's on/off status and duration according to ambient temperature parameters and their predicted changes, optimizing protection while reducing energy waste during periods when protection is not needed
