Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heating systems fail to optimize the use of stored heat from solar accumulators, often requiring fossil fuel-based generators to operate unnecessarily, wasting energy and increasing costs.
Innovation Solution
The heat generator is only switched on when the solar accumulator's heat is insufficient to meet the heating circuit's demands, ensuring that stored energy is prioritized and fossil fuels are used only when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the heat generator is switched on whenever the heating circuit requires heat, then the heating demand is reliably met, but the heat generator operates unnecessarily when the heat accumulator has sufficient stored energy, wasting fossil fuels and increasing costs
Solution Approach 1:
The control unit continuously monitors the temperature in the heat accumulator and compares it with the return temperature of the heating circuit. This feedback mechanism enables the system to automatically switch between operating modes (heat accumulator support vs. heat generator) based on real-time thermal conditions, ensuring optimal energy utilization while reliably meeting heating demands.
Solution Approach 2:
The system dynamically adjusts its operating mode based on the thermal state of the heat accumulator. When the accumulator temperature exceeds the return temperature by at least 5 K, the system switches to accumulator support mode, bypassing the heat generator. This dynamic adaptation allows the system to optimize fossil fuel consumption without compromising heating reliability.
2Productivity
If the heat generator is frequently switched on and off, then the system responds quickly to changing heating demands, but the heat generator experiences excessive wear and reduced lifespan
Solution Approach 1:
The heat accumulator pre-stores thermal energy during periods of excess supply (e.g., sunny days), preparing the system in advance for future heating demands. This preliminary action reduces the need for frequent heat generator startups, thereby extending its operational life while maintaining quick response capability when actual heating is required.
Solution Approach 2:
The system recovers and stores excess heat energy in the accumulator during periods when heating demand is low or solar supply is high. This recovered energy is then utilized during peak demand periods, reducing the frequency of heat generator operation and extending its service life while maintaining heating productivity.
3Loss of energy
If the system prioritizes using stored heat from the heat accumulator, then fossil fuel consumption is reduced, but the heat generator may not be switched on in time when the accumulator's heat is insufficient
Solution Approach 1:
The control unit continuously monitors the temperature difference between the heat accumulator and the heating circuit return. When this difference falls below the 5 K threshold, the system immediately switches to heat generator mode, ensuring timely response. The feedback mechanism balances energy optimization with rapid response by dynamically adjusting the operating mode based on real-time thermal conditions.
Solution Approach 2:
The system changes its operational parameters (operating mode) based on the thermal state of the heat accumulator. By monitoring temperature parameters and switching between accumulator support mode and heat generator mode, the system optimizes fossil fuel consumption while ensuring timely heat supply through parameter-based control.

AI summary
The invention relates to a method for operating a heating system, in which heat stored in a heat accumulator (1) is fed to a heating circuit (3) of the heat generator (2) to support a heat generator (2) when the heat accumulator (1) minus a predetermined hysteresis value, a higher temperature than is determined at the return of the heating circuit (3). According to the invention, the heat generator (2) is only switched on with ongoing support from the heat accumulator (1) if a setpoint temperature required from the heating circuit (3) is greater than a temperature prevailing in the heat accumulator (1).
