Split Fan Panel Assembly for Duct Type Air Conditioners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Duct type air conditioners with single fan panels face challenges in handling and assembly due to increased weight, requiring careful handling and reduced workspace, making maintenance and repair cumbersome.
Innovation Solution
The air conditioner is designed with multiple separate fan panels, each with a motor support and fan unit, reducing the overall weight and size of the fan mechanism, allowing for easier handling and assembly, and enabling individual unit replacement during maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If mechanical components are mounted to a single fan panel in a large duct type air conditioner, then the structural integrity and stability are improved, but the weight of the assembly is increased to such extent that one worker cannot handle the assembly, causing an assembling performance to deteriorate
Solution Approach 1:
The single fan panel is divided into multiple separate fan panels (first fan panel and second fan panel). Each fan panel can be handled and assembled separately by one worker, improving assembling performance while maintaining structural integrity through proper mounting on the front plate
2Stability of the object's composition
If mechanical components are mounted to a single fan panel, then the structural stability is improved, but even when one component is to be replaced, it is needed to remove said single fan panel with the result that the handling of such air conditioner is required to be done with the same level of care as heavy objects with the result that the availability of a work space lowers and the working environment also deteriorates
Solution Approach 1:
The fan mechanism is segmented into multiple independent fan panels mounted on the front plate. When one component needs replacement, only the specific fan panel containing that component needs to be removed, not the entire assembly. This significantly improves ease of repair and reduces the weight handling requirements during maintenance
Solution Approach 2:
The problematic heavy single fan panel assembly is extracted and replaced with multiple lighter separate fan panels. This extraction allows selective removal of individual panels for component replacement, improving both ease of repair and working environment
3Stability of the object's composition
If a single fan panel is used, then the structural integrity is maintained, but the total weight of fan units is increased, requiring careful handling and reduced workspace
Solution Approach 1:
The heavy single fan panel is segmented into multiple lighter fan panels. The total weight is distributed across several separate units, each with its own motor and fan components. This segmentation maintains the overall structural integrity of the air conditioner while reducing the weight of individual components that need to be handled

AI summary
There is provided a duct type air conditioner that solves problems of assembling properties and serviceability.The duct type air conditioner includes a front plate formed with a discharge duct mounting frame outwardly thereof so as to surround discharge openings, a fan mechanism mounted inwardly of the front plate by way of a fan panel interposed therebetween, a back plate formed with a suction duct mounting frame outwardly thereof so as to surround the suction opening, and a heat exchanger mounted inwardly of the back plate so as to face the fan mechanism. The fan mechanism includes two fan units having separate fan panels such as formed by dividing a fan panel into two panels, motors mounted on the respective separate fan panels, and fans positioned inwardly of the separate fan panels and driven by the motors. The respective fan units are mounted inwardly of the front plate by attaching the respective fan panels to the front plate on the inside thereof.
