Shared Intermediate Plate for Multi-Compressor Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In refrigeration cycles with multiple compressors, the limited space within the machine chamber poses a challenge for compact layout and effective vibration isolation, especially when increasing compressor capacity or using two-stage compression.
Innovation Solution
A refrigeration cycle apparatus with multiple compressors supported by a shared intermediate plate through elastic members, which is itself supported by a bottom member, allowing for a more compact arrangement and improved vibration isolation by distributing the weight and optimizing the center of gravity for reduced vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple compressors are arranged separately in the machine chamber, then each compressor can be individually supported, but the implementation area becomes larger and space utilization is poor
Solution Approach 1:
The patent merges multiple compressors onto a single intermediate plate, which is supported by multiple elastic members on the bottom member. This combining approach reduces the implementation area by consolidating the space required for multiple separate mounting locations into one shared platform, while the multiple elastic members collectively provide enhanced vibration isolation for all compressors.
2Area of stationary object
If multiple compressors are placed on a shared intermediate plate, then the implementation area is reduced, but the overall weight increases affecting the vibration isolation
Solution Approach 1:
The patent changes the parameters of the elastic members by increasing their quantity and adjusting their physical properties (such as elasticity coefficient) to match the increased overall weight of the intermediate plate and compressors. This ensures that the vibration isolation performance is maintained despite the weight increase, as the elastic members are specifically designed to handle the combined load.
3Reliability
If separate intermediate plates are used for each compressor, then individual vibration isolation is achieved, but the device complexity and space requirement increase
Solution Approach 1:
The patent combines multiple compressors onto a single intermediate plate structure, reducing the number of separate mounting components needed. This merging approach simplifies the overall structure by eliminating the need for multiple individual intermediate plates and their associated mounting hardware, while the multiple elastic members provide collective vibration isolation for all compressors.
4Object-affected harmful factors
If compressors are arranged with maximum spacing for vibration isolation, then vibration transmission is reduced, but the machine chamber space is insufficient
Solution Approach 1:
The patent introduces elastic members as intermediary elements between the intermediate plate and the bottom member. These elastic members act as mediators that isolate vibrations from the compressors, allowing the compressors to be positioned closer together within the limited machine chamber space while still effectively reducing vibration transmission to the housing.
