What is the difference between a hermetic and a semi-hermetic compressor?
A. A hermetic compressor has all parts enclosed in a welded shell.
B. A semi-hermetic compressor has a motor with valves above the cylinders.
C. A semi-hermetic compressor has pistons and a crankshaft.
Answer (2)
Hermetic compressors are fully sealed and require complete replacement if they fail, while semi-hermetic compressors allow for easier maintenance and repair. The latter has accessible motors and often features pistons and crankshafts for larger applications. Understanding these differences is crucial for choosing the right compressor for your needs. ;
A hermetic compressor is fully sealed and cannot be repaired if it fails, requiring complete replacement. In contrast, a semi-hermetic compressor has accessible components that allow for easier maintenance and repair, making it more suitable for larger applications. Choosing between the two depends on the specific refrigeration needs and maintenance considerations.
