Nested Intake-Exhaust Duct Assembly for Packaged Air Conditioners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaged air conditioners with dual air pipes are complex to install and have an unsightly appearance, leading to poor user experience and inefficient heat exchange.
Innovation Solution
A dual-air-pipe structure is formed by arranging an air exhaust pipe and an air intake pipe that sleeves the air exhaust pipe, with a connection pipe linking the air exhaust pipe to the air exhaust volute, creating a sealed heat exchange duct and improving user experience and energy efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two independent air pipes are used for air intake and exhaust, then the air conditioner can exchange heat with the outdoor environment, but the structure becomes complicated and difficult to install
Solution Approach 1:
The air intake pipe is designed to sleeve the air exhaust pipe, with the air intake channel formed between the inner wall of the air intake pipe and the outer wall of the air exhaust pipe. This nested configuration integrates two independent air pipes into a compact unified structure, maintaining separate air intake and exhaust functions while significantly reducing structural complexity and installation difficulty.
2Reliability
If two independent air pipes are used for air intake and exhaust, then the air conditioner can exchange heat with the outdoor environment, but the appearance becomes unsightly
Solution Approach 1:
By nesting the air intake pipe around the air exhaust pipe, the design consolidates two separate components into a single integrated assembly. This reduces the visual clutter and occupies less space, resulting in a more aesthetically pleasing appearance while preserving the heat exchange functionality.
3Reliability
If a connection pipe is added to link the air exhaust pipe to the air exhaust volute, then the sealing performance is improved, but the device complexity increases
Solution Approach 1:
The connection pipe is integrated into the existing air exhaust pipe structure, forming a continuous sealed pathway from the air exhaust channel through the connection pipe to the air exhaust volute. This merging approach enhances sealing performance by eliminating potential leakage points while avoiding the need for additional separate connection components.

AI summary
An air intake and exhaust assembly includes an air exhaust pipe, a connection pipe, and an air intake pipe arranged adjacent to the air exhaust pipe. The air exhaust pipe includes an air exhaust channel formed in the air exhaust pipe. One end of the connection pipe is connected to a lower end of the air exhaust pipe and another end of the connection pipe is configured to be connected to an air exhaust volute of a packaged air conditioner, such that the air exhaust channel is communicated with an air outlet of the air exhaust volute. An air intake channel is formed between an inner wall of the air intake pipe and an outer wall of the air exhaust pipe, and the air intake channel is communicated with an air inlet of the packaged air conditioner.
