Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing reciprocating compressors with separate suction and discharge mufflers face issues such as increased assembly complexity, refrigerant leakage, suction loss due to overheating, and higher material costs, which affect compressor performance and efficiency.
Innovation Solution
An integral muffler design is introduced, where the suction and discharge noise devices are integrally formed with a connection-fixing device, reducing the number of components, minimizing assembly procedures, and using materials with varying internal pressure strengths to prevent leakage and enhance mechanical properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If separate suction and discharge mufflers are used, then noise removal effectiveness is improved, but assembly complexity and device structure increase
Solution Approach 1:
The patent merges the suction muffler and discharge muffler into a single integrated muffler unit. The suction noise device and discharge noise device are combined within one housing structure, reducing the number of separate components from two to one, thereby simplifying assembly procedures while maintaining noise removal effectiveness for both suction and discharge sides.
2Object-affected harmful factors
If separate suction and discharge mufflers are used, then noise removal effectiveness is improved, but refrigerant leakage risk increases
Solution Approach 1:
By integrating the suction and discharge mufflers into a single unit with a unified housing and sealing structure, the patent reduces the number of connection interfaces and sealing points. This integrated design eliminates potential leakage paths that would exist between separate muffler components, thereby improving reliability and preventing refrigerant leakage while maintaining effective noise removal.
3Object-affected harmful factors
If separate suction and discharge mufflers are used, then noise removal effectiveness is improved, but material costs and manufacturing complexity increase
Solution Approach 1:
The integrated muffler design consolidates the housing, suction noise device, and discharge noise device into a single manufactured component or assembly. This reduces the total material consumption compared to two separate mufflers and simplifies manufacturing processes. The unified structure allows for more efficient production and reduces overall material costs while maintaining the noise removal effectiveness of both suction and discharge sides.
4Object-affected harmful factors
If separate suction and discharge mufflers are used, then noise removal effectiveness is improved, but the number of components and assembly procedures increase
Solution Approach 1:
By combining the suction and discharge mufflers into one integrated unit, the patent reduces the number of components that need to be assembled. Instead of installing two separate mufflers with multiple fastening operations, the integrated design allows for a single installation process, thereby improving assembly efficiency and productivity without compromising noise removal effectiveness.

AI summary
A muffler for a compressor and a compressor having the same are provided, in which a suction noise device and a discharge noise device may be integrally formed to reduce a number of components of a suction side muffler and a discharge side muffler so as to reduce leakage of refrigerant generated at an assembled portion of the muffler, and to reduce a length of a suction passage and a discharge passage. Such a division between the suction noise device and the discharge noise device may prevent discharged refrigerant from unintentionally heating suctioned refrigerant, which may reduce suction loss. The formation of the suction and discharge noise devices using a plastic material may reduce fabricating costs, and the structures of the suction and discharge side noise spaces may be simplified and noise removal effects may be improved, reducing an overall size of the muffler and improving noise effects.
