Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional building heating systems are inefficient due to significant heat losses during distribution, and they contribute to environmental issues through high gas consumption and emissions.
Innovation Solution
The method involves disconnecting and removing an existing boiler and connecting an air source heat pump to the existing fluid line, air inlet pipe, and flue gas discharge pipe, utilizing the existing infrastructure for efficient installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a centralized boiler system is used to heat building water, then the system structure is simple and easy to install, but significant heat losses occur during heat transport over large distances
Solution Approach 1:
The patent divides the centralized heating system into multiple distributed heat pump units, each serving specific zones or recipients within the building. This segmentation eliminates long heat transport distances and reduces distribution losses, while maintaining manageable system complexity through modular deployment
2Object-generated harmful factors
If an oil or gas boiler is used for heating, then the system can provide sufficient heating capacity, but it consumes fossil fuels and emits harmful substances
Solution Approach 1:
The patent changes the energy source parameter from fossil fuels (oil/gas) to renewable electricity, and changes the heating mechanism parameter from direct combustion to heat pump technology with electrical compression cycles, thereby eliminating harmful emissions while maintaining heating capacity
Solution Approach 2:
The patent replaces the mechanical combustion system of traditional boilers with an electrical heat pump system that uses electrical compression and phase change mechanisms to generate heat, substituting chemical energy conversion with electrical energy conversion
3Loss of energy
If a new heating system is installed to replace the existing boiler, then energy efficiency can be improved, but installation time and cost increase
Solution Approach 1:
The patent designs the heat pump units to serve multiple functions including heating water for taps, utility water, and central heating systems, allowing a single infrastructure installation to replace multiple separate systems and reduce overall installation time
Solution Approach 2:
The patent utilizes the existing infrastructure (fluid lines, air inlet pipes, flue gas discharge pipes) that has already been installed in the building, performing preliminary preparation work before the heating system renewal to minimize on-site installation time and disruption
