Convoluted Refrigerant Line Isolation for Compressor Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air conditioning systems, particularly those with screw compressors, face challenges in reducing vibration and noise transmission due to rigid refrigerant lines that carry high-pressure refrigerant, causing operational noise and vibration propagation to other system components.
Innovation Solution
A vibration isolation apparatus is introduced, featuring a convoluted conduit structure connected between the compressor and refrigerant pipes, with stabilizing members and structural supporting elements to absorb and impede vibration, utilizing vibration isolation members to decouple the structural supporting members from the stabilizing members, thereby reducing vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid pipes are used to withstand high refrigerant pressure, then structural strength is improved, but vibration transmission to other components increases
Solution Approach 1:
The rigid pipe system is segmented by introducing a flexible conduit section between the compressor and other components. This segmentation allows the rigid pipes to maintain structural strength while the flexible conduit isolates vibration, preventing transmission to other system components.
Solution Approach 2:
A flexible conduit acts as an intermediary element between the rigid high-pressure pipe system and the compressor. This intermediary absorbs and isolates vibration while allowing the rigid pipes to maintain their pressure-containing function.
2Stress or pressure
If rigid refrigerant lines are used to carry high-pressure refrigerant, then pressure containment is improved, but noise generation increases
Solution Approach 1:
The refrigerant line is segmented into rigid sections for pressure containment and a flexible conduit section for vibration isolation. This segmentation allows the system to maintain pressure containment while reducing noise generation from vibration.
Solution Approach 2:
A flexible conduit with convoluted structure is introduced into the rigid refrigerant line system. This flexible section absorbs vibration and reduces noise while the rigid sections maintain pressure containment capability.
3Object-generated harmful factors
If a flexible conduit is used to absorb vibration, then vibration isolation is improved, but structural supporting capability deteriorates
Solution Approach 1:
The system is segmented into flexible vibration-isolating sections and rigid structural supporting sections. The flexible conduit provides vibration isolation while the rigid pipes and supporting structures maintain the necessary structural strength for pressure containment.
Solution Approach 2:
The invention merges the functions of flexible vibration isolation and rigid structural support into a single integrated system. The flexible conduit with convoluted structure combines vibration-absorbing flexibility with sufficient structural integrity to handle refrigerant flow.

The apparatus effectively reduces vibration and noise levels in air conditioning systems by up to 10-15 dB, enhancing the structural integrity to withstand high refrigerant pressures and minimizing vibration propagation through the convoluted conduit's flexible design.
Implementation Method 1
the vibration of the compressor may migrate to other parts of the air conditioning system through a flow passage including a suction line and/or a discharge line, causing noise
Implementation Method 2
The conduit may have a convoluted structure to absorb vibration
Implementation Method 3

AI summary
A vibration isolation apparatus for an air conditioning system may include a flow passage, at least a portion of which has a convoluted structure. The flow passage may also be coupled to two stabilizing members. The vibration isolation apparatus may include a structural supporting member to retain the two stabilizing members. The rod may be isolated from the stabilizing members by vibration isolation members. The vibration isolation apparatus may be positioned in a refrigeration line between an outlet of a compressor and a refrigerant pipe. The stabilizing members, the convoluted flow passage and the vibration isolation members may attenuate the vibration generated by the compressor so as to reduce the vibration transmitted to the refrigerant pipe. The structural supporting member may enhance the structural strength of the vibration isolation apparatus to withstand the pressure of the compressed refrigerant.
