Solution Overview
Problem
Existing heating systems face challenges in efficiently and cost-effectively adjusting heating output to changing heat requirements within buildings, often relying on complex and costly individual room temperature measurements and direct volume flow measurements.
Innovation Solution
A heating system with a control and/or regulation unit that adjusts the heat generator unit's output based on pump output parameters from a speed-controlled circulation pump and radiator valve position, using sensors to detect current consumption and speed, allowing for rapid and needs-based adjustments without direct volume flow measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual room temperature measurements and direct volume flow measurements are used to adjust heating output, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the essential information needed for heating control (pump power and valve position) and uses this subset of data instead of comprehensive room temperature and direct volume flow measurements. This reduces measurement system complexity while maintaining sufficient control accuracy.
Solution Approach 2:
The patent introduces pump power and valve position as intermediary parameters that indirectly represent the actual heating demand and flow conditions. These intermediaries simplify the measurement system by avoiding direct temperature sensing in each room and direct volume flow measurement, while still enabling effective heating output adjustment.
2Productivity
If rapid adjustment of heating output to changing heat requirements is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback control mechanism where the control unit continuously monitors pump power and valve position, and automatically adjusts the heating output accordingly. This enables rapid response to changing heat requirements while keeping the control logic relatively simple by focusing on these two key parameters rather than complex multi-room temperature feedback.
Solution Approach 2:
The patent enables dynamic adjustment of heating output by continuously varying the heating generator's power based on real-time pump performance characteristics and valve positions. This dynamic control allows rapid adaptation to changing thermal demands without requiring a complex system architecture.
3Loss of energy
If cost-effective heating system operation is achieved, then loss of energy is reduced, but measurement precision deteriorates
Solution Approach 1:
The patent enables the heating system to self-regulate by using the pump's own performance characteristics and valve positions as control inputs. This self-service approach reduces energy waste by automatically matching heating output to actual demand without requiring expensive external measurement systems, achieving cost-effective operation with sufficient (though not highly precise) measurement capability.
