Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern, airtight buildings face challenges in achieving acceptable indoor air quality due to lack of natural ventilation, leading to high CO2 levels, humidity issues, and increased risks of mold and allergy symptoms, which existing ventilation systems often fail to adequately address, especially in terms of ease of maintenance and compatibility with advanced building materials and construction methods.
Innovation Solution
A ventilation radiator system with a large air flow cross-sectional area, simple and robust design, easy filter replacement, and efficient air flow regulation, featuring a flat duct with horizontal air deflection and a filter holder that can be easily accessed and cleaned, along with an air flow regulating plate to control air introduction, ensuring comfortable and healthy indoor air quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a ventilation system is installed in modern airtight buildings, then indoor air quality is improved, but device complexity and maintenance difficulty increase
Solution Approach 1:
The patent combines the ventilation function with the heating radiator into a single integrated unit. The ventilation radiator serves dual purposes: heating the room and providing fresh air intake with filtration. This merging eliminates the need for separate ventilation systems, reducing overall device complexity while maintaining air quality improvements.
Solution Approach 2:
The ventilation radiator is designed as a multi-functional device that simultaneously performs heating, ventilation, and air filtration. The same radiator structure that heats the room also serves as the air intake path for fresh air, and the filter integrates into this dual-function design. This universality reduces the number of separate components needed.
2Object-affected harmful factors
If fine filters are used to ensure air quality, then air filtration effectiveness is improved, but pressure drop and air flow resistance increase
Solution Approach 1:
The patent specifies using F7 class filters which represent a particular filtration efficiency level. By selecting this specific filter class, the system achieves adequate air quality improvement while managing the pressure drop characteristics. The filter design and positioning are optimized to balance filtration effectiveness with air flow resistance.
3Productivity
If the radiator is sealed to prevent air leakage, then ventilation efficiency is improved, but accessibility for filter replacement deteriorates
Solution Approach 1:
The ventilation radiator is designed with separable components that allow the filter to be accessed and replaced independently from the main radiator body. The filter is positioned in a location that can be accessed by opening the radiator housing or removing specific panels, enabling maintenance without compromising the sealed ventilation path when the system is assembled.
4Productivity
If the air path is made wide and open to reduce pressure drop, then air flow rate is improved, but the risk of air infiltration increases
Solution Approach 1:
The air intake path is merged with the radiator structure itself, using the radiator's wide surface area as the air flow path. This integration allows for a large effective air flow area that reduces pressure drop while the radiator housing provides the sealing function to prevent unwanted air infiltration. The convection plates and housing work together to maintain sealed pathways.
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
The system provides effective ventilation, maintaining recommended CO2 levels, relative humidity, and air flow rates, reducing health risks and operational complexity, while being adaptable to various building types and activities.
Implementation Method 1
the fresh air is heated when the thermostat has stopped the water circulation in the radiator. It is possible to let the interior air flow through the cool radiator and thus heat up the radiator body and with it the incoming outside air
Implementation Method 2
Modern ventilation radiators not only heat the air flowing into the room and prevent cold drafts, but also filter the air at the same time, i.e. free it of dust in particular

AI summary
An air vent (2) feeds outside air to a radiator. The vent is a cassette duct which encases the uptight radiator on four vertical sides. The duct inlet and outlet have guide vanes in-line with the direction of flow through the radiator. The inlet zone further incorporates a push-fit air filter.
