Priority-Based Indoor Unit Control for Outdoor Unit Energy Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for controlling multiple indoor units connected to an outdoor unit in IoT environments face challenges in energy efficiency due to varying cooling/heating capacities and different heat change rates across separate interior spaces, making coordinated control difficult and inefficient.
Innovation Solution
A method and apparatus that identify the high efficiency range of the outdoor unit and prioritize the operation of indoor units based on energy consumption and comfort zone requirements, recalculating priorities as needed to optimize energy use and maintain comfort zones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If indoor units are individually controlled without coordination, then each indoor unit can operate independently to meet local comfort needs, but the overall energy efficiency of the outdoor unit deteriorates
Solution Approach 1:
The system segments indoor units into different priority groups (first priority, second priority, third priority) based on their operational characteristics and comfort requirements. This segmentation allows the outdoor unit to be controlled in a coordinated manner while still meeting individual indoor unit requirements, resolving the contradiction between independent control and overall energy efficiency.
Solution Approach 2:
The control system dynamically adjusts the operation of indoor units based on real-time conditions, outdoor unit efficiency ranges, and priority levels. The outdoor unit operates in different modes (first operation mode, second operation mode, third operation mode) corresponding to different efficiency ranges, enabling adaptive energy optimization while maintaining individual indoor comfort needs.
2Use of energy by moving object
If indoor units are controlled in a coordinated way to improve energy efficiency, then overall energy consumption decreases, but scheduling becomes more difficult due to different high efficiency ranges of outdoor units
Solution Approach 1:
The system changes operational parameters by defining specific priority levels for different indoor units and establishing corresponding control strategies. First priority indoor units are controlled to maintain outdoor unit operation in high efficiency ranges, while second and third priority units are adjusted accordingly. This parameter-based approach simplifies the scheduling complexity by providing clear control rules rather than requiring complex real-time optimization algorithms.
3Use of energy by moving object
If the outdoor unit operates in high efficiency ranges, then energy consumption is reduced, but the ability to meet diverse cooling/heating demands of different interior spaces is limited
Solution Approach 1:
The system segments indoor units into different priority groups based on their operational characteristics and comfort requirements. First priority indoor units are controlled to maintain outdoor unit operation in high efficiency ranges, while second and third priority units are adjusted accordingly. This segmentation allows the system to prioritize energy efficiency for critical spaces while maintaining adaptability for other spaces.
Solution Approach 2:
The control system implements periodic adjustment of indoor unit operations, switching between different operation modes of the outdoor unit based on accumulated energy efficiency data and changing indoor conditions. This periodic action allows the system to maintain high efficiency operation while periodically adapting to meet diverse indoor demands.
