Heating Control Using Window Detection and Stored Room Heat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heating system control methods fail to account for heat stored in rooms, leading to unnecessary high heating and energy consumption when windows are opened, causing the system to overshoot the target temperature.
Innovation Solution
A method that monitors the actual room temperature and its gradient, using the last measured temperature before a window opening to control the heat generator when the gradient indicates a window is open, and continuing to use this temperature even after the window is closed to utilize stored heat for reheating, while avoiding high energy expenditure and temperature overshooting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the heat generator heats with high output after window closing to restore target temperature, then the room temperature is brought back to target level, but energy consumption increases unnecessarily and temperature overshooting occurs
Solution Approach 1:
The system detects window opening in advance and preemptively reduces heat generator output before the window is closed, rather than reacting after temperature drops. This preliminary action prevents unnecessary heating cycles and utilizes stored heat in building structures, avoiding energy waste and temperature overshooting while maintaining comfortable temperature levels.
2Speed
If the heat generator operates at full load after window closing, then the room is heated quickly, but the stored heat in floors, walls and furnishings causes overshooting of target temperature
Solution Approach 1:
The system continuously monitors room temperature and detects window opening events by analyzing temperature gradients. When window opening is detected, the control device adjusts heat generator output based on feedback from temperature sensors, preventing both excessive heating and temperature overshooting by adapting to real-time thermal conditions and stored heat release patterns.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces energy consumption and prevents overheating by leveraging stored heat in the room's furnishings, floors, and walls, ensuring efficient heating and maintaining the target temperature.
Implementation Method 1
at least one temperature sensor for determining the actual room temperature in the room to be heated
Implementation Method 2
a heat generator (30)... for heating at least one room (100)
Implementation Method 3
heat generator heats with a very high and even highest heating level in order to bring the room to be heated back up
Implementation Method 4
there is still so much heat in the room to be heated due to the heat storage in the floors, walls and furnishings that is given off to the room
Implementation Method 5
heat stored in the room, ie heat stored in the floor, the walls and furnishings of the room to be heated
