Question 83Refrigeration & AC - 1st Asst/Chief

The correct answer is B) prevent liquid slugging or overloading the compressor. When starting a refrigeration system after a prolonged shutdown, the compressor should not be run continuously at full capacity. Doing so could lead to liquid refrigerant entering the compressor, known as "liquid slugging," which can damage the compressor. Instead, the compressor should be operated in short, intermittent spurts or the suction isolation valve should be throttled to gradually cool the refrigerated compartment. This allows the refrigerant to properly evaporate and prevents the compressor from being overloaded, protecting the system from potential damage. The other options are incorrect because A) is not necessary, C) is an incomplete explanation, and D) is unrelated to the purpose of the starting procedure.
