Solution Overview
Problem
Refrigeration circuits face performance issues due to vortices and liquid components in the working fluid transferred between the evaporator and compressor, which affect the overall efficiency and uniformity of the fluid.
Innovation Solution
A piping assembly with deflector plates attached to the inner wall of the cavity, forming a transition between the inlet and outlet portions, designed to straighten the fluid flow and capture liquid components, improving fluid uniformity and reducing liquid content by creating parallel flow paths and utilizing porous materials for enhanced liquid capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional piping is used to transfer working fluid from evaporator to compressor, then the piping structure is simple, but the working fluid contains vortices and liquid components that adversely affect compressor performance
Solution Approach 1:
The piping assembly is divided into three distinct portions: inlet portion, transition portion, and outlet portion. Each portion serves a specific function in managing the working fluid flow. The inlet portion receives fluid with vortices, the transition portion contains straightening portions that eliminate vortices and separate liquid components, and the outlet portion delivers uniform gaseous fluid to the compressor. This segmentation allows the system to address the technical contradiction by creating a complex but functional structure that improves compressor performance.
Solution Approach 2:
The transition portion acts as an intermediary between the inlet and outlet portions. It contains straightening portions with deflector plates that mediate the transformation of working fluid from a state with vortices and liquid components to a uniform gaseous state. This intermediary structure performs the critical function of vortex elimination and liquid-gas separation, resolving the contradiction between simple piping and improved compressor performance.
2Stability of the object's composition
If the piping assembly includes straightening portions with deflector plates to eliminate vortices and separate liquid components, then the uniformity of working fluid is improved, but the device complexity increases
Solution Approach 1:
The straightening portions are strategically placed within the transition portion at specific locations where vortex elimination and liquid separation are most needed. The deflector plates are positioned to create localized flow straightening zones without requiring the entire piping assembly to be complex. This local application of quality improvement resolves the contradiction by achieving working fluid uniformity through targeted structural features rather than throughout the entire system.
Solution Approach 2:
The straightening portions utilize porous materials or porous structures that facilitate liquid component separation while allowing gaseous working fluid to pass through. These porous elements provide a mechanism for liquid-gas separation based on material properties rather than complex mechanical structures, thereby improving working fluid uniformity while controlling device complexity.
3Loss of substance
If porous materials are used in straightening portions for enhanced liquid capture, then liquid component removal is improved, but manufacturing complexity increases
Solution Approach 1:
The porous materials used in the straightening portions have controlled pore size parameters that are optimized for liquid component capture while maintaining ease of manufacture. By selecting porous materials with appropriate pore dimensions and distributions, the system achieves effective liquid removal without requiring complex manufacturing processes. The parameter optimization of porous material properties resolves the contradiction between enhanced liquid capture and manufacturing simplicity.
