Refrigerant Compressor Gap Filter to Prevent Spiral Nozzle Blockage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerant compressors in air-conditioning systems face blockages due to particles, which reduce efficiency and can lead to malfunctions, necessitating additional filters that increase production costs and installation space.
Innovation Solution
A gap filter with defined geometric shape and dimensions is formed in the compressor housing to filter out blocking particles, eliminating the need for separate filters and minimizing space and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate filter is installed in front of the spiral nozzle insert, then particles are filtered out and blockages are prevented, but the device complexity, installation space, and production costs increase
Solution Approach 1:
The filter function is merged with the housing structure by forming a gap filter directly in the housing in front of the spiral nozzle insert. This integration eliminates the need for a separate filter component while maintaining the particle filtration function, thereby reducing device complexity and installation space.
Solution Approach 2:
The housing structure is given multiple functions: it not only provides structural support but also incorporates a filter function through the formed gap. This multi-functionality approach eliminates the need for dedicated filter components, reducing both device complexity and production costs while maintaining blockage prevention.
2Reliability
If a separate filter is installed to filter particles, then blockages are prevented, but production costs and installation space increase
Solution Approach 1:
The filter function is merged with the housing structure through gap formation, eliminating the need for separate filter components. This reduces the number of parts to be manufactured and assembled, thereby lowering production costs and simplifying the manufacturing process.
Solution Approach 2:
The housing is designed to serve multiple purposes including structural support and particle filtration through the integrated gap filter. This multi-functionality reduces the total component count and assembly steps, leading to lower production costs and simpler installation.
3Productivity
If the spiral nozzle has a reduced cross-section to generate back pressure, then compression efficiency is improved, but the risk of particle blockage increases
Solution Approach 1:
The gap filter is positioned in front of the spiral nozzle insert to perform preliminary particle filtration before the refrigerant enters the reduced cross-section spiral nozzle. This preliminary action removes particles that could cause blockages, allowing the spiral nozzle to maintain its reduced cross-section for efficient compression without increased blockage risk.
