Hermetic Refrigerant Condenser Connection Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hermetically encapsulated refrigerant compressors experience efficiency losses due to heat transfer from the compressor housing to the suction and pressure pipes, which heats the refrigerant before compression, reducing the compressor's efficiency.
Innovation Solution
A connection device with a body element and spacer element is used to create a thermal barrier, distancing the body element from the suction or pressure pipe, and the body element is attached to the compressor housing outside the connection opening, with materials like austenitic steel, foam glass, or ceramic materials used to minimize heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the suction pipe or pressure pipe is connected directly to the compressor housing, then the connection is simple and reliable, but heat transfer from the compressor housing to the pipe causes refrigerant heating and efficiency losses
Solution Approach 1:
A connection device with a body element and spacer element is introduced as an intermediary component between the compressor housing and the suction/pressure pipe. The spacer element creates a thermal barrier that reduces heat transfer from the compressor housing to the refrigerant-carrying pipe, while the body element maintains the hermetic seal and mechanical connection. This intermediary structure resolves the contradiction by providing both reliable connection and thermal isolation.
2Loss of energy
If insulation is added to the suction and pressure pipes, then heat transfer is reduced, but the device complexity increases
Solution Approach 1:
The connection device integrates multiple functions into a single component assembly: the body element provides the hermetic seal and mechanical attachment, while the spacer element provides thermal insulation. By merging the sealing function and insulation function into one integrated connection device, the patent reduces overall device complexity compared to adding separate insulation layers to already-connected pipes.
3Stability of the object's composition
If the body element is placed in direct contact with the suction or pressure pipe, then the connection is stable, but heat transfer to the refrigerant increases
Solution Approach 1:
The spacer element serves as a thermal intermediary between the body element and the suction/pressure pipe. It maintains the mechanical stability of the connection while blocking the direct thermal path from the body element to the refrigerant, thus preventing unnecessary heating of the refrigerant while preserving connection stability.
