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 A) welded, fully hermetic.
The illustration GS-RA-41 shows a refrigeration compressor, and a fully hermetic compressor has the drive mechanism, typically an electric motor, fully sealed and welded into the compressor unit. This design is common for small refrigeration systems and ensures a completely sealed, airtight system that requires minimal maintenance. The other options, such as an external-drive, open, or semi-hermetic design, would not match the illustration provided.
