What is the purpose of running a refrigeration compressor in short intermittent spurts or throttling the suction isolation valve when starting the system after a prolonged shutdown?

Correct Answer: Option A — prevent liquid slugging or overloading the compressor

Throttling the suction valve or running the compressor in short bursts after a shutdown prevents liquid slugging and excessive initial suction loads caused by refrigerant migration and crankcase oil dilution.
