Solution Overview
Problem
Existing temperature control systems for buildings, such as those using underfloor heating, lack efficient self-regulation mechanisms that can adapt to individual room conditions and user behavior, often resulting in inefficient energy use and comfort issues.
Innovation Solution
A self-regulating adjustment device for flow control valves in consumer loops with heat exchangers, which adjusts the volume flow of a heating medium based on activation and deactivation durations, linked with control influences from prior art, to maintain an energy-efficient operating range and adapt to user behavior without requiring a central control unit or extensive wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a central control unit with extensive sensor networks is used to regulate temperature control systems, then measurement precision and control accuracy are improved, but device complexity and installation cost increase
Solution Approach 1:
The patent divides the temperature control system into independent consumer loops, each with its own flow control valve and control logic. This segmentation eliminates the need for a centralized control unit while maintaining precise temperature control in each zone independently.
Solution Approach 2:
Each consumer loop is equipped with self-regulating capabilities through flow control valves that automatically adjust based on local temperature conditions. The system serves itself without external control, reducing complexity while maintaining measurement precision through local sensing and actuation.
2Loss of energy
If flow control valves are manually adjusted for hydraulic balancing, then energy efficiency is improved, but loss of time and labor cost increase
Solution Approach 1:
The flow control valves are designed with dynamic adjustment capabilities, allowing them to automatically adapt to changing thermal loads and conditions. This eliminates the need for manual hydraulic balancing while maintaining optimal energy efficiency through continuous automatic optimization.
Solution Approach 2:
The system incorporates feedback mechanisms where temperature sensors monitor local conditions and automatically adjust flow control valve positions. This closed-loop control achieves energy efficiency without manual intervention, eliminating the time and labor required for manual hydraulic balancing.
3Adaptability or versatility
If temperature control systems are designed with individual room adaptation, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system is segmented into independent consumer loops, each capable of individual room adaptation. This modular approach allows each zone to be customized for its specific thermal characteristics without increasing overall system complexity, as each segment operates autonomously with identical control logic.
Solution Approach 2:
The patent employs universal control components and algorithms that can be applied to any consumer loop regardless of specific room characteristics. This multi-functionality allows individual room adaptation while maintaining consistent, simple control logic across the entire system.
