Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If outdoor reset curve is used for heating control, then building temperature control is achieved, but energy waste occurs due to lack of systematic adjustment and feedback
Solution Approach 1:
The patent implements a feedback mechanism where energy consumption data from the energy meter is continuously monitored and fed back to the energy optimizer. The energy optimizer then adjusts the outdoor reset curve parameters based on this feedback to minimize energy consumption while maintaining comfort. This closed-loop control system enables systematic adjustment of heating parameters based on actual energy usage patterns.
Solution Approach 2:
The outdoor reset curve is transformed from a static, manually configured parameter set into a dynamic, automatically adjusting system. The energy optimizer continuously modifies the reset curve parameters in response to changing energy consumption data and outdoor temperature conditions, enabling the system to adapt optimally to varying operational conditions throughout the heating season.
2Ease of manufacture
If conventional heating control is used, then simple control logic is maintained, but unnecessary costs and emissions result
Solution Approach 1:
The heating control system performs self-optimization through the energy optimizer, which automatically adjusts the outdoor reset curve parameters using energy consumption data from the energy meter. This eliminates the need for manual commissioning adjustments and systematic reviews by technicians, enabling the system to self-correct and self-optimize its performance throughout the heating season, thereby reducing emissions without increasing operational complexity.
Solution Approach 2:
The patent replaces manual mechanical adjustment of heating parameters with an automated electronic optimization system. The energy optimizer uses computational algorithms to process energy meter data and automatically adjust control parameters, substituting the manual technician review and adjustment process with an automated electronic system that continuously optimizes performance and reduces emissions.
3Ease of operation
If outdoor reset curve parameters are manually set, then initial configuration is simple, but parameters are rarely reviewed and optimized
Solution Approach 1:
The energy optimizer enables continuous optimization of the outdoor reset curve parameters throughout the heating season, replacing the traditional approach where parameters were set once during commissioning and rarely reviewed. The system continuously monitors energy consumption data and automatically adjusts parameters in real-time, ensuring optimal performance without requiring periodic manual interventions or technician reviews.
