Compact Ventilation Layout With Integrated Air Purification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional ventilation systems require additional space and separate air purifiers, leading to inefficiencies in spatial and economic usage, and may directly introduce polluted outdoor air into indoor environments.
Innovation Solution
A compact ventilation system with integrated air purifying capabilities, featuring a case with inlets and outlets, an air supply duct, a fan, an air guide, and an air purifying member that purifies air before it is supplied to the indoor space, allowing for both ventilation and air purification without raising the floor height or requiring a separate air purifier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional ventilation system is installed within the ceiling, then ventilation function is provided, but the floor height between bottoms of upper and lower floors must be increased
Solution Approach 1:
The air purifying member is arranged in the radial direction of the fan rather than the axial direction, utilizing the horizontal space within the ceiling. This dimensional reconfiguration allows the purification function to be added without increasing the vertical floor height, thereby resolving the contradiction between providing ventilation function and maintaining compact floor height.
2Ease of operation
If a separate air purifier is purchased to purify indoor air, then air purification function is provided, but additional expense and device complexity are required
Solution Approach 1:
The air purifying member is integrated into the ventilation system's case, combining the ventilation fan and air purification functions into a single unified device. This merging eliminates the need for a separate air purifier, reducing both additional expenses and device complexity while providing both ventilation and air purification functions simultaneously.
Solution Approach 2:
The ventilation system is designed to perform multiple functions: it provides both ventilation by moving air and air purification through the integrated air purifying member. This multi-functionality allows a single device to replace what would traditionally require two separate devices (ventilation system and air purifier), thereby reducing system complexity and cost.
3Productivity
If outdoor air is introduced by the ventilation system, then ventilation is achieved, but polluted outdoor air is directly supplied to the room
Solution Approach 1:
The air purifying member is positioned to purify outdoor air before it is supplied to the room. By performing purification in advance (preliminary action) as air enters through the inlet, the system ensures that only cleaned air is introduced into the indoor space, thereby maintaining high ventilation efficiency while eliminating harmful pollutants.
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 effectively purifies indoor air and supplies fresh outdoor air, enhancing indoor environments while reducing construction costs and eliminating the need for additional air purification units, thereby improving spatial and economic efficiency.
Implementation Method 1
a fan provided within the case, the fan sucking air introduced into the case via the air supply duct, the fan blowing out the sucked air to the at least one outlet
Implementation Method 2
an air purifying member situated next to a lateral side of the fan between the fan and the at least one outlet to purify the air blown from the fan
