Pipe conduit panel and floor structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In underfloor heating systems, continuous connecting lines pose challenges in temperature regulation due to their layout, leading to overheating in small rooms and inefficiencies in energy use, as they must be laid with small laying distances and can cause excessive heating in adjacent areas.
Innovation Solution
A pipeline panel with adjustable pipe guide channels that allow for height changes, enabling connecting pipelines to be raised from an insulation level to a higher screed level, reducing overheating and improving temperature control by integrating pipes directly into the insulation level, thus allowing for separate heating circuit installation and regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If connecting pipelines are laid on insulation over bare floor, then heat dissipation is constant and meets regulatory requirements, but rooms become overheated and energy efficiency decreases
Solution Approach 1:
The patent introduces a vertical dimension change by raising connecting pipelines from the floor level (first laying plane) to the screed level (second laying plane) using pipeline panels with inclined pipe guide channels. This dimensional transition allows pipes to be positioned within the thermal mass of the screed rather than remaining on the insulation surface, thereby reducing unwanted heat dissipation into the floor structure and improving room temperature control and energy efficiency.
2Temperature
If connecting pipelines are raised from insulation level to screed level, then temperature control is improved and overheating is reduced, but height offsets and construction steps must be compensated
Solution Approach 1:
The patent divides the floor structure into distinct segments: the insulation layer at floor level, the pipeline panel with inclined channels for height transition, and the screed layer at the elevated level. This segmentation allows connecting pipelines to be laid on the insulation up to the door frame area, then transitioned vertically through the pipeline panel to the screed level, compensating for height offsets without requiring complex continuous structures.
Solution Approach 2:
The pipeline panels incorporate inclined and curved pipe guide channels that smoothly transition pipes from the horizontal floor level to the elevated screed level. This curved transition path within the pipeline panel effectively compensates for construction-related steps and ledges, enabling seamless height compensation while maintaining pipeline integrity.
3Ease of operation
If connecting pipelines are laid with small laying distances, then continuous supply lines can be installed, but adjacent rooms are heated above target temperature
Solution Approach 1:
The patent extracts the connecting pipelines from the room level insulation and repositions them to the screed level using pipeline panels with inclined channels. By removing pipes from the direct path over small rooms and corridors and elevating them into the thermal mass of the screed, the system prevents these pipes from contributing to overheating in adjacent rooms while maintaining the ease of continuous pipeline installation.
