Solution Overview
Problem
Existing heating systems face inefficiencies in controlling room temperatures across multiple rooms, leading to poor energy balance and increased operational costs due to full-load operations triggered by extreme temperature differences in individual rooms.
Innovation Solution
A method that compares temperature differences across rooms to prioritize energy distribution, adjusting heat exchange performance in each room through operating parameters like flow rates and control valve settings to divert energy flow dynamically, ensuring rapid temperature achievement while maintaining energy efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the heat source device is operated at full load to quickly reach target temperature in the guide room, then the temperature control speed is improved, but the energy efficiency deteriorates
Solution Approach 1:
The patent applies dynamics by making the heat exchange performance of individual heat exchangers dynamically adjustable based on real-time temperature differences. Instead of operating the entire heating system at fixed full load, each heat exchanger's performance is individually optimized according to its room's specific needs, allowing rapid temperature correction where required while minimizing energy consumption elsewhere.
Solution Approach 2:
The patent implements local quality by treating each room's heat exchanger independently with customized control parameters. The guide room receives focused heating attention with higher priority control, while other rooms receive appropriate heating based on their smaller temperature differences. This localized control approach avoids the energy waste of heating all rooms at full load when only one room requires urgent temperature correction.
2Stability of the object's composition
If the heat source device operates at full load to maintain target temperatures in all rooms, then the temperature stability is improved, but the energy consumption increases
Solution Approach 1:
The patent changes the control parameters of individual heat exchangers based on their specific temperature differences. The guide room's heat exchanger operates with higher performance parameters to ensure rapid and stable temperature achievement, while other rooms' heat exchangers operate with reduced parameters proportional to their smaller temperature deviations. This parameter differentiation maintains overall temperature stability across all rooms while significantly reducing total energy consumption compared to uniform full-load operation.
3Loss of energy
If individual room control is implemented to improve energy efficiency, then the energy balance is improved, but the system complexity increases
Solution Approach 1:
The patent segments the central heating system into individually controllable heat exchanger units, each with its own control parameters. This segmentation allows independent optimization of each room's heating based on its specific temperature difference, improving energy balance. The complexity is managed by implementing a hierarchical control structure where a central controller coordinates the segmented units based on simple temperature difference comparisons, avoiding the need for overly complex distributed control systems.
