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

Running a compressor in short intervals or throttling the suction valve after prolonged shutdowns prevents liquid slugging and excessive oil foaming caused by refrigerant migration and boiling in the crankcase.
