Air Conditioning Sensor Re-Association for Accurate Temperature Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioning control systems in stores face challenges in maintaining accurate temperature control when the position of temperature sensors changes, leading to inefficient energy use and failure to reach the target temperature due to the distance between air conditioning units and sensors.
Innovation Solution
A control system that associates air conditioning apparatuses with temperature sensors based on the fastest change rate of measured temperature, allowing for dynamic adjustment of target temperatures and preventing excessive heating or cooling by calculating correction temperatures based on reference values and measured change rates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If temperature sensors are fixedly installed at specific positions to control air conditioning apparatuses, then the control system is simple to implement, but the system fails to maintain accurate temperature control when sensor positions change or when sensors are placed too far from air conditioning units
Solution Approach 1:
The patent applies dynamics by transitioning from fixed sensor-apparatus associations to dynamic re-association based on change rate measurements. The system periodically determines which sensor has the fastest temperature change rate and re-associates it with the corresponding air conditioning apparatus, allowing the control relationships to adapt dynamically to sensor position changes while maintaining measurement accuracy.
Solution Approach 2:
The system implements self-service through automatic re-association functionality. When sensor positions change, the control apparatus automatically detects the fastest temperature change rate among sensors and re-associates them with appropriate air conditioning apparatuses without requiring manual intervention, thereby maintaining accurate temperature control while simplifying operation.
2Ease of manufacture
If temperature sensors are placed far from air conditioning apparatuses for ease of installation, then installation is simpler, but the temperature control accuracy deteriorates due to distance effects
Solution Approach 1:
The patent applies feedback by continuously monitoring the temperature change rate at each sensor position and using this information to determine optimal sensor-apparatus associations. The system measures how quickly temperature changes occur at each sensor location and uses this feedback to dynamically re-associate sensors with the nearest or most relevant air conditioning apparatus, ensuring accurate temperature control regardless of initial sensor placement.
3Measurement precision
If the system continuously monitors all temperature sensors to detect position changes, then temperature control accuracy is maintained, but energy consumption increases
Solution Approach 1:
The patent applies periodic action by implementing re-association at specific intervals or under specific conditions rather than continuously. The system periodically determines the fastest temperature change rate among sensors and performs re-association only when necessary, thereby maintaining temperature control accuracy while reducing unnecessary energy consumption from continuous monitoring and adjustment operations.
