Integrated Conduit Absorber for Air-Conditioning Pressure Pulses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing absorbing devices for reducing pressure pulses in air-conditioning systems are complex and require expensive fabrication, with a need for separate parts that increase system costs and complexity.
Innovation Solution
A hollow, enclosed chamber integrated between opposing ends of an air-conditioning conduit, formed from two connectable pot parts with reduced passage openings and tapered transitional sections, allowing for reduced diameters while maintaining expansion rate and performance, and optionally using coaxial mouthpieces for increased expansion rate and performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional absorbing device with complex internal arrangement is used, then the pressure pulse absorption function is achieved, but the device complexity and fabrication cost increase
Solution Approach 1:
The absorbing device is divided into two separate pot parts that are connectable to each other. Each pot part is integrally formed with a respective end of the air-conditioning conduit, eliminating the need for complex internal arrangements while maintaining the pressure pulse absorption function through the reduced passage opening and tapered transitional section design.
2Reliability
If separate parts are used in the absorbing device, then the pressure pulse absorption function is achieved, but the fabrication cost increases
Solution Approach 1:
Each pot part is integrally formed with a respective end of the air-conditioning conduit, merging the absorbing device with the conduit structure. This eliminates the need for separate fabrication of additional parts and reduces overall fabrication cost while maintaining the pressure pulse absorption function through the optimized geometry of the reduced passage opening and tapered transitional section.
3Volume of moving object
If the diameter of the absorbing element is reduced, then the device size is reduced, but the expansion rate and performance may be compromised
Solution Approach 1:
The device incorporates a reduced passage opening with a tapered transitional section that creates localized expansion zones. This allows the overall device diameter to be reduced while maintaining the necessary expansion rate for pressure pulse absorption through the optimized local geometry of the tapered sections, which provide the required flow expansion without increasing the overall device size.

AI summary
The absorbing device includes a hollow enclosed chamber including two pot parts. Open ends of the pot parts are connectable to each other by welding or soldering. Each of the pot parts is integrally formed in an opposing end of an air-conditioning conduit, wherein open ends of the pot parts are oriented toward each other. Each of the pot parts is provided with a reduced passage opening interconnected with an internal space of the air-conditioning conduit via a tapered section.
