Refrigerant Suction Guide Structure for Reciprocating Compressor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reciprocating compressors experience reduced efficiency due to high flow resistance in the suction channels, which prevents optimal inhalation of refrigerant gas, leading to inefficiencies in the compressor's operation.
Innovation Solution
The refrigerant suction guide structure incorporates inclined surfaces within the suction channels of the piston to guide refrigerant flow, reducing resistance and enhancing the amount of refrigerant inhaled by the compressor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional straight suction channels are used, then the structure is simple, but the flow resistance of inhaled refrigerant is high which reduces compressor efficiency
Solution Approach 1:
The suction channels are designed with curved surfaces instead of straight channels. The curved surfaces guide the refrigerant flow smoothly from the suction port through the piston, reducing turbulence and flow resistance. This curvature allows refrigerant to follow a more natural flow path, improving inhalation efficiency while maintaining structural simplicity.
2Quantity of substance
If the suction channel diameter is increased to reduce flow resistance, then more refrigerant can be inhaled, but the piston size and device complexity increase
Solution Approach 1:
By curving the suction channels, the effective flow path length is optimized and flow resistance is reduced without increasing the channel diameter. This allows adequate refrigerant quantity to be inhaled while maintaining compact piston dimensions.
Solution Approach 2:
The channel geometry parameters (curvature radius, inclination angle) are optimized to achieve the best balance between flow resistance reduction and piston volume maintenance. The curved surfaces with specific geometric parameters enable efficient refrigerant flow through the existing piston volume.

AI summary
A refrigerant suction guide structure of a reciprocating compressor is provided. The refrigerant suction guide structure includes a cylinder having an accommodating space inside, a piston having suction channels through which refrigerant is inhaled inside and inserted into the cylinder to be in a linear reciprocating motion, a suction valve included in the end of the piston to open and close the suction channels, and a valve fixing member for combining the suction valve with the piston. The suction channels of the piston include inclined surfaces for guiding refrigerant to the outside in which the suction valve is first opened. The suction channels are formed so as to be inclined to reduce flow resistance of inhaled refrigerant such that the amount of the inhaled refrigerant is increased. Therefore, it is possible to improve the efficiency of a compressor.
