Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heating systems often waste energy due to inaccurate adjustment of the heat curve, leading to either customer dissatisfaction or excessive energy consumption, as installers typically set the curve too high to avoid complaints, and frequent adjustments are costly.
Innovation Solution
The method adjusts the heat curve by comparing emitted heat to a maximum level, decreasing the slope when heat is low and increasing it when heat is high, using a predetermined fraction of maximum heat emission, and maintaining the curve when heat is within a specific range, allowing for automatic adjustment and optimal heat delivery based on demand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the heat curve is set too high to avoid customer complaints, then customer satisfaction is improved, but energy waste increases
Solution Approach 1:
The heating system automatically adjusts the heat curve based on measured heat emission data without requiring manual installer intervention. The control device autonomously optimizes the heat curve by comparing actual heat emission to the maximum level and automatically modifying the slope accordingly, eliminating the need for conservative high-setting adjustments while preventing energy waste.
Solution Approach 2:
The system implements a feedback mechanism where the control device continuously monitors the heat emission from heat exchangers and uses this information to automatically adjust the heat curve. By measuring actual heat emission and comparing it to the maximum level, the system receives feedback that enables precise optimization of the heat curve slope, resolving the contradiction between customer satisfaction and energy efficiency.
2Loss of energy
If the heat curve is adjusted accurately to minimize energy waste, then energy efficiency is improved, but adjustment costs increase due to multiple installer visits
Solution Approach 1:
The heating system performs automatic heat curve adjustment without requiring installer intervention. The control device autonomously measures heat emission, calculates the optimal heat curve slope, and implements adjustments automatically, completely eliminating the need for multiple installer visits while achieving accurate energy optimization.
Solution Approach 2:
The manual mechanical adjustment process by installers is replaced with an automated electronic control system. The control device uses electronic sensors to measure heat emission and electronically adjusts the heat curve parameters, substituting the mechanical installer intervention process with an automated electronic system that achieves the same optimization goal without the associated time and cost.
3Reliability
If the supply temperature is increased to ensure adequate heating, then heating reliability is improved, but energy consumption increases
Solution Approach 1:
The heat curve slope is made dynamically adjustable based on actual heat emission conditions. Instead of using a fixed high supply temperature to ensure heating reliability, the system automatically optimizes the supply temperature by adjusting the heat curve slope according to measured heat emission data, achieving reliable heating only when necessary and reducing energy consumption when full heating capacity is not needed.
