Floor Construction Drying With HEPA Filter Belt Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drying methods for building components, particularly floor constructions, suffer from pollutant contamination of room air due to the release of microorganisms and pollutants during drying, inefficiency, high energy consumption, and negative impact on sound insulation.
Innovation Solution
Utilizing a HEPA filter belt, preferably H13, to seal air outlet openings and edge joints, allowing dry air to absorb moisture while preventing pollutant release into the room air, and maintaining air flow to enhance drying efficiency and sound insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If positive pressure drying is used to dry floor constructions, then drying effectiveness is improved, but pollutant release into room air increases
Solution Approach 1:
A HEPA filter is introduced as an intermediary component between the drying system and the room environment. The filter allows moisture-laden air to pass through while trapping pollutants, spores, and microorganisms, thus mediating between the drying process and indoor air quality requirements
Solution Approach 2:
The air outlet system is segmented into multiple components: the HEPA filter medium itself, a support structure, and a housing. This segmentation allows each component to be optimized independently - the filter media for pollutant capture, the support for structural integrity, and the housing for installation and maintenance accessibility
2Object-generated harmful factors
If negative pressure drying is used to extract moist air, then pollutant release is reduced, but energy consumption increases
Solution Approach 1:
Instead of using negative pressure (extraction) to achieve pollutant containment, the invention inverts the approach by using positive pressure drying combined with a HEPA filter at the outlet. This allows the beneficial effects of positive pressure (better drying performance) while achieving pollutant containment through filtration rather than extraction
3Object-generated harmful factors
If edge joints are sealed to prevent pollutant release, then indoor air quality is improved, but sound insulation decreases
Solution Approach 1:
The sealing approach is applied locally rather than globally. HEPA filters are installed specifically at air outlet openings and extraction points where pollutant release occurs, while edge joints and other building envelope elements maintain their original sound-insulating properties. This localized application preserves sound insulation in non-critical areas
4Object-generated harmful factors
If HEPA filter belt is used to seal air outlets, then pollutant release is prevented, but device complexity increases
Solution Approach 1:
The invention uses flexible HEPA filter belts that can be rolled out and installed over air outlet openings and extraction points. These thin film filters are easy to position and secure, replacing complex rigid filtration systems while maintaining effective pollutant containment
Solution Approach 2:
The HEPA filter belts are designed as replaceable, cost-effective components that can be easily installed and removed. Rather than investing in permanent, complex filtration infrastructure, the system uses affordable filter belts that can be swapped out when needed, reducing overall system complexity and cost
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively prevents pollutant release, reduces energy consumption, and maintains sound insulation by using a HEPA filter belt to seal air outlets and edge joints during building drying processes.
Implementation Method 1
completely closing and, in particular, sealing the air outlet opening with a HEPA filter, in particular with a HEPA filter H13
Implementation Method 2
Flowing dry air into the air inlet opening by means of an air supply device of an air dehumidification system, so that moisture from the floor construction is taken up or absorbed by the dry air and discharged from the air outlet opening together with the dry air
