Solution Overview
Problem
Conventional hybrid heating devices with heat pumps and gas heating blocks face limitations in achieving high temperatures, requiring a switch to gas heating when higher temperatures are needed, and lack flexibility in energy sources and usage efficiency.
Innovation Solution
A hybrid heating system with at least two heating units, including a fuel heating block and a heat pump, where an alternative electric heating block can be easily installed or exchanged, allowing for flexible operation based on energy requirements and temperature needs, with a compact design that includes a buffer tank and fluid control elements for efficient heat management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a heat pump is used to supply heat energy, then energy efficiency is improved, but the maximum temperature is limited to around 55°C
Solution Approach 1:
The heating system dynamically switches between heat pump operation and gas heating block operation based on temperature requirements. When high temperatures are needed, the gas heating block is activated; when moderate temperatures suffice, the heat pump operates, optimizing energy efficiency while meeting temperature demands.
Solution Approach 2:
The heating device integrates two different heating principles (heat pump and gas heating block) into a single system, allowing it to function effectively across a wide temperature range by selecting the appropriate heating method based on requirements.
2Temperature
If a gas heating block is switched on for higher temperatures, then temperature requirements are met, but fossil fuel consumption increases
Solution Approach 1:
The system changes the operating parameters by switching between two different heating technologies based on temperature requirements. The gas heating block is used only when necessary for high temperatures, while the heat pump handles moderate temperature requirements, thereby reducing overall fossil fuel consumption.
Solution Approach 2:
The control system monitors temperature requirements and automatically switches between heating sources. When the heat pump can meet the temperature demand, it operates; when higher temperatures are required, the gas heating block is activated, optimizing the balance between temperature fulfillment and fossil fuel usage.
3Adaptability or versatility
If an alternative electric heating block is installed for flexibility, then adaptability to energy changes is improved, but device complexity increases
Solution Approach 1:
The heating system is divided into separate, independently controllable heating units (heat pump and gas heating block). This segmentation allows each unit to be optimized for specific operating conditions while maintaining overall system flexibility. The units can be selectively activated based on energy availability and temperature requirements.
Solution Approach 2:
The system maintains flexibility through dynamic control of multiple heating units. The alternative electric heating block can be easily installed or exchanged, and the control system dynamically selects which heating unit to operate based on energy prices, availability, and temperature requirements, achieving adaptability without requiring complex integration.
