Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressors in heat pumps and refrigeration systems experience undesirable vibration transmission, leading to structure-borne and airborne noise due to their mounting configurations, despite the use of damping elements.
Innovation Solution
A holder is connected to the compressor housing in the intermediate area, featuring a collar or belt that supports feet or surfaces, which are attached via elastic elements to a base, optimizing the attachment point to minimize vibration transmission by aligning with the compressor's low-vibration rest line, enhancing stability and noise reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If damping elements are used to minimize vibration transmission, then vibration transmission is reduced, but unwanted vibrations are still transmitted to large-area components causing structure-borne and airborne noise
Solution Approach 1:
The patent extracts the harmful vibration transmission path by detaching the compressor from the base plate and suspending it independently using elastic elements. The compressor housing is separated from direct contact with the base plate, removing the transmission path for structure-borne noise while maintaining operational stability through the elastic suspension system.
Solution Approach 2:
Elastic elements serve as intermediary components between the compressor housing and the mounting structure. These elastic elements act as vibration isolators that decouple the compressor from the base plate, allowing the compressor to be suspended without rigid connections that would transmit vibrations to large-area components and generate noise.
2Stability of the object's composition
If the compressor is mounted at the lower end with feet or support points, then the compressor is stable, but vibrations are transmitted to the base plate causing noise
Solution Approach 1:
The patent replaces the traditional mechanical rigid mounting system (feet or support points welded to a bracket) with an elastic suspension system. Instead of rigid mechanical connections that transmit vibrations, elastic elements are used to suspend the compressor, substituting the mechanical transmission path with an elastic isolation mechanism that prevents noise generation.
3Reliability
If rigid mounting is used to ensure stability, then the compressor is securely mounted, but vibrations are transmitted causing structure-borne and airborne noise
Solution Approach 1:
The patent changes the mechanical parameter of the mounting connection from rigid to elastic. By introducing elasticity into the mounting system through elastic elements, the connection becomes compliant and capable of absorbing vibrations while maintaining secure attachment. This parameter change allows the mounting to remain reliable while preventing vibration transmission to the base plate.

AI summary
The invention relates to a compressor (1) with a housing (2) having an upper end (3) and a lower end (4) and a cylindrical intermediate section (5) with a cylinder axis (6), for installation with a vertical cylinder axis (6), wherein a support (8) is provided which is connected to the housing (2) in the cylindrical intermediate section (5), extends from there to below the lower end (4), and terminates in three, four, or more feet (11) or a support area with three, four, or more contact surfaces. The support (8) is preferably connected to the housing (2) approximately in the middle of the intermediate section (5), particularly preferably in a low-vibration section (7) near a compressor equilibrium line (15) determined by tests and/or calculations.The present invention makes it possible to keep a compressor (1) low in vibration, so that during its operation hardly any vibrations are transmitted to other structures that could generate unwanted airborne noise.
