Duct type air conditioning device and method for assembling and disassembling the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Duct type air conditioning devices face challenges with air leakage and increased workability due to the large number of fixing screws required for connecting the blowing and heat exchanging portions, which complicates repairs and requires multiple workers for heavy components.
Innovation Solution
The use of link members with extension portions that form multiple airtight points by being inserted into grooves on the cabinets' plates, reducing the number of fixing screws needed and enhancing the airtight seal between the blowing and heat exchanging portions, allowing for easier connection and disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple fixing screws are used to connect the blowing portion and heat exchanging portion, then the connection strength is improved, but the ease of repair deteriorates due to increased disassembly time and complexity
Solution Approach 1:
The partition panel is divided into multiple sections with individual link members for each section. Each link member can be independently removed, allowing partial disassembly for targeted repairs without requiring removal of all fastening elements, thus reducing repair time while maintaining connection strength where needed.
Solution Approach 2:
The link members are designed to be separable and reconfigurable, transitioning from a fixed multi-screw connection to a dynamic system where connection points can be quickly adjusted or removed based on maintenance needs, improving ease of repair while maintaining structural integrity during operation.
2Reliability
If multiple fixing screws are used to connect the blowing portion and heat exchanging portion, then the connection reliability is improved, but the device complexity increases due to more fastening components
Solution Approach 1:
The link members serve multiple functions: they provide structural connection, ensure airtight sealing through groove engagement, and facilitate easy disassembly for maintenance. This multi-functionality replaces the need for separate fastening and sealing components, reducing device complexity while maintaining connection reliability.
Solution Approach 2:
The fastening and sealing functions are merged into a single link member structure. The link members engage with grooves on the partition panel, simultaneously providing mechanical attachment and airtight sealing, thereby reducing the number of separate components needed while ensuring reliable connection.
3Manufacturing precision
If the cabinet is lifted to connect the coupling portion into the coupling groove, then the connection precision is improved, but the ease of operation deteriorates due to heavy components requiring multiple workers
Solution Approach 1:
The link members are designed to engage with grooves at the same elevation level on the partition panel, eliminating the need to lift one cabinet relative to another. The connection points are positioned such that both cabinets can be aligned horizontally and connected without vertical displacement, making the operation easier while maintaining precision.
4Object-affected harmful factors
If the link members form multiple airtight points by being inserted into grooves, then the air leakage prevention is improved, but the device complexity increases due to additional structural features
Solution Approach 1:
The grooves on the partition panel serve dual purposes: they guide the link members into proper alignment for precise connection and simultaneously create multiple airtight sealing points. This multi-functionality prevents air leakage without requiring separate sealing components, thus not increasing device complexity.

AI summary
A duct type air conditioning apparatus is provided with a blowing portion including a first cabinet in which a blower assembly is installed and a heat exchanging portion including a second cabinet in which a heat exchanger is installed. The air conditioning apparatus includes a partition panel arranged between the first and second cabinets and connected to facing sides of the first and second cabinet, and first and second link members separably fastened along an upper end and a lower end of the partition panel to keep an airtight seal in a connection portion between the first and second cabinets.
