Solution Overview
Problem
Existing heating systems struggle with inefficient energy consumption due to incorrect switching between heating and non-heating operations, particularly in transition periods, leading to unnecessary energy costs and discomfort, as they rely on volatile outside temperature fluctuations.
Innovation Solution
A method for operating state monitoring that determines a setpoint value for the heating system based on a consumption prediction value, using a consumption prediction function that considers outside temperature and energy consumption thresholds, allowing for robust and efficient switching between heating and non-heating modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the heating system switches operating state based on outside temperature, then the system can adapt to environmental conditions, but incorrect switching decisions occur due to temperature volatility
Solution Approach 1:
The system performs preliminary evaluation by calculating an energy consumption indicator before making the switching decision. This preliminary calculation uses the outside temperature to predict energy consumption, and only when this predicted consumption exceeds a threshold does the system switch to heating mode. This prevents premature or incorrect switching due to temporary temperature fluctuations.
Solution Approach 2:
The patent introduces an energy consumption indicator as an intermediary between the outside temperature and the switching decision. Instead of directly switching based on temperature, the system first converts temperature into an energy consumption prediction, then uses this intermediate value to make the final switching decision. This intermediary layer filters out the volatility of raw temperature data.
2Ease of operation
If manual switching of operating state is used, then operator control is maintained, but switching occurs too late resulting in unnecessary energy consumption
Solution Approach 1:
The system continuously monitors outside temperature and automatically calculates the energy consumption indicator, providing real-time feedback about when switching is necessary. This automated feedback loop ensures timely switching decisions without requiring manual operator intervention, thereby preventing unnecessary energy consumption while maintaining the ability for operators to override decisions if needed.
Solution Approach 2:
The heating system performs self-monitoring and self decision-making regarding operating state switching. The system automatically evaluates the energy consumption indicator and switches states without manual intervention, enabling it to serve itself in making optimal switching decisions based on current environmental conditions.
3Ease of operation
If heating system operates in warm months, then heating function is available, but unnecessary energy consumption occurs
Solution Approach 1:
Before activating heating in warm months, the system preliminarily evaluates the outside temperature against the energy consumption threshold. This preliminary check prevents unnecessary heating activation when temperatures are sufficiently warm, while still maintaining the heating function's availability when truly needed.
Solution Approach 2:
The system dynamically adjusts the heating operation based on the outside temperature parameter. When the temperature parameter indicates warm conditions, the energy consumption indicator remains below the threshold and heating is suppressed. When temperature drops and the indicator exceeds the threshold, heating activates. This parameter-based control optimizes energy usage while maintaining heating availability.
