🔍 Key Concepts

• Difference between open, semi-hermetic, and fully hermetic refrigeration compressors • How the motor is arranged relative to the crankcase (inside the shell vs outside, directly coupled vs belt or coupling) • Visual clues such as bolted access covers, welded shell, and any external drive components

💭 Think About

• Look closely at figure B: can you see any separate motor, shaft, belts, or coupling outside the compressor shell? What does that tell you about the drive? • Do you see any large bolted joint or crankcase cover that could be removed for internal servicing, or is the shell a single sealed container? • Which drive arrangement type is typically used when the motor and compressor are enclosed together in a sealed steel shell to prevent refrigerant leaks?

✅ Before You Answer

• Confirm whether the shell in figure B has bolted joints or appears continuously welded/sealed • Verify if there is an external motor or drive shaft visible outside the compressor body • Match that visual evidence to the option that describes a sealed shell with the motor and compressor inside
