Solution Overview
Problem
Existing heating systems face challenges in efficiently controlling temperature across different spaces in a building, especially when there are varying usage patterns and external influences such as solar radiation and outside temperature.
Innovation Solution
A system comprising at least one heat exchanger per heated space, a heat generation unit, and a control device that adjusts the heating unit based on the difference between setpoint and actual temperatures, allowing for precise control of room temperature and energy savings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a heating system uses multiple heating points with individual control valves and room temperature controllers, then the temperature control precision for different rooms is improved, but the device complexity increases due to multiple controllers and data bus communication
Solution Approach 1:
The patent combines multiple room temperature controllers and control valves into a single integrated heating unit with a central control device. This merging approach maintains the ability to control different rooms independently while reducing the overall number of separate components and simplifying the system architecture.
Solution Approach 2:
The heating unit is designed as a universal device that can serve multiple rooms simultaneously, with the control device capable of managing different heating points through a single unit. This multi-functional design eliminates the need for separate controllers in each room while maintaining precise temperature control.
2Ease of operation
If the heating unit operates autonomously without external electrical control signals, then the ease of operation is improved, but the adaptability to different room requirements decreases
Solution Approach 1:
The heating unit incorporates autonomous operation capabilities where the integrated control device can automatically regulate heating without external intervention. The system monitors temperature conditions and adjusts heating output independently, maintaining ease of operation.
Solution Approach 2:
The control device is designed to be dynamically adaptable, allowing it to adjust its operation based on different room requirements and conditions. This dynamic capability enables the system to switch between autonomous operation and responsive control modes as needed.
3Ease of operation
If the heating system uses a central temperature sensor for ambient temperature, then the ease of operation is improved, but the measurement precision for individual room temperatures decreases
Solution Approach 1:
The patent introduces an integrated control device as an intermediary that receives temperature information and coordinates heating output for multiple rooms. This intermediary enables the system to operate with simplified temperature sensing while maintaining the ability to control individual room temperatures through centralized coordination.

AI summary
System and method for operating a heating unit in a building with one or more rooms to be heated. The method comprises the steps of providing one or more setpoint temperatures Tn,setpoint for one or more rooms to be heated; providing an actual temperature Tn,actual for the one or more rooms to be heated; determining a difference ΔTn between a setpoint Tn,setpoint of a room to be heated and the actual temperature Tn,actual of the room to be heated; and controlling a heating unit depending on the determined difference ΔTn.
