Heat Generator Output Sizing via Daily Energy Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining the required output of a heat generator often rely on theoretical assumptions, leading to oversized systems and inefficiencies, particularly due to changes in building insulation and varying heating demands between hot water preparation and space heating.
Innovation Solution
A method that measures energy consumption in domestic and heating water circuits over a day, using heat meters to determine daily energy values, which are then processed to calculate specific power requirements, accounting for parallel or priority operations, and adjusting for factors like vacancy rates and outside temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heat generator output is determined using theoretical assumptions and safety margins, then legal protection for heating engineers is achieved, but the heat generator becomes oversized and inefficient
Solution Approach 1:
The patent applies feedback by continuously monitoring actual energy consumption through heat meters in both domestic water and heating water circuits, then using this real data to determine the required heat generator output. This replaces theoretical assumptions with actual measured feedback, allowing precise sizing without oversizing while maintaining reliability.
Solution Approach 2:
The system performs self-service by automatically measuring energy consumption and calculating required output without needing manufacturer-specific interfaces or external tools. The heat meters and evaluation device work autonomously to determine the optimal heat generator size based on actual property consumption patterns.
2Power
If heat generator is designed based on space heating requirements, then heating demand is met, but hot water preparation demand may not be satisfied in highly insulated buildings
Solution Approach 1:
The patent segments the heating system into two separate measured circuits: domestic water heating circuit and heating water circuit. By independently measuring energy consumption in each circuit through separate heat meters, the system can determine the specific power requirements for each function and ensure the heat generator is adequately sized for both space heating and hot water preparation.
3Measurement precision
If manufacturer-specific interfaces are used to access heat generator data, then device-specific information is obtained, but the method becomes restricted to particular manufacturers
Solution Approach 1:
The patent introduces heat meters as intermediary devices installed in the domestic water and heating water circuits. These heat meters measure energy consumption directly at the point of use and provide data to an evaluation device, serving as a neutral intermediary that enables precise measurement without needing to access manufacturer-specific interfaces or proprietary systems.
