Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of heating installations with heat pumps lack means to compare actual performance with advertised performance and verify energy savings, and are not provided with information on the ecological footprint of their installations.
Innovation Solution
A method and device for indicating the consumption and efficiency of heating installations by determining and displaying energy quantities Q2F (billed energy) and Q3 (free energy taken from the external environment) over a predetermined period, using sensors and meters, and calculating financial equivalents to provide users with information on economic and ecological performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If heat pump systems are used to reduce energy consumption and ecological footprint, then energy efficiency is improved, but users lack means to verify actual performance and savings
Solution Approach 1:
The patent implements a feedback mechanism by providing users with real-time or periodic information about their heating installation's actual energy consumption and performance through displays, documents, or electronic communication. This allows users to verify whether the heat pump system is delivering the expected energy savings and compare actual performance with advertised performance, thereby resolving the information asymmetry between theoretical efficiency claims and actual operational performance.
2Loss of information
If detailed energy measurement and display systems are implemented, then user information on performance is improved, but device complexity increases
Solution Approach 1:
The patent employs an intermediary device or system that acts as a mediator between the complex heat pump installation and the user. This intermediary handles the measurement, calculation, and presentation of energy performance data, simplifying the interface between the complex technical system and the end user. The intermediary can process raw sensor data, calculate energy consumption and savings, and present this information in an easily understandable format through displays or documents, thereby managing complexity while providing comprehensive performance information.
