What is the drive arrangement of refrigeration compressor shown in figure "B" of the illustration? Illustration GS-RA-41
AI Explanation
The correct answer is C) welded, fully hermetic.
This is the correct answer because a fully hermetic refrigeration compressor has a welded casing that is not designed to be serviced. This type of compressor is sealed and not accessible for maintenance, which makes it a more reliable and durable design for marine applications where accessibility may be limited.
The other options are incorrect - option A describes a semi-hermetic compressor that is designed to be serviced, option B refers to an open drive compressor which has an external drive mechanism, and option D describes an external-drive compressor which is not a fully integrated, hermetic design.
