Air duct device and air handling apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioning systems require separate installation of air ducts for temperature and humidity regulation and air purification, lacking an integrated solution for both functions.
Innovation Solution
An integrated air duct system with a first air duct for heat exchange and a second air duct for purification, where the air input end of the second duct passes by the output end of the first duct, allowing for heat exchange and air purification within a shared housing, reducing temperature fluctuations and noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate air duct systems are used for temperature regulation and air purification, then each system can be optimized independently, but the device complexity and installation requirements increase
Solution Approach 1:
The patent combines the air conditioner and ventilator into a single integrated unit that shares a common air duct system. The air duct device includes both a cooling air duct and a purification air duct that are merged into one structure, allowing both temperature regulation and air purification functions to be performed through a unified system rather than separate installations.
Solution Approach 2:
The integrated air duct device performs multiple functions simultaneously: it serves as both a cooling duct for the air conditioner and a purification duct for the ventilator. The shared air duct structure enables the system to handle both temperature control and air purification tasks through a single multi-functional component.
2Reliability
If separate air conditioner and ventilator installations are used, then each device can be independently optimized, but the installation space and cost increase
Solution Approach 1:
The patent merges the air conditioner and ventilator into a single integrated installation with a shared housing and common air duct system. This consolidation reduces the total installation space required compared to having two separate devices, while still allowing each function to be independently optimized through dedicated components within the integrated structure.
3Temperature
If the air input end of the second air duct passes by the air output end of the first air duct, then heat exchange between ducts is improved, but the risk of air flow interference increases
Solution Approach 1:
The patent divides the air duct system into separate segments: a cooling air duct and a purification air duct, each with dedicated input and output ends. The segmentation allows the ducts to pass by each other for heat exchange while maintaining independent air flow paths, thus preventing interference between the cooling and purification air streams.
Solution Approach 2:
The patent applies different structural characteristics to different parts of the air duct system. The section where the cooling and purification ducts pass by each other is designed with specific insulation and spatial arrangement to enable heat exchange, while other sections maintain separate and distinct air flow paths to prevent interference.
