Question 60Refrigeration & AC - Assistant Engineer

The correct answer is C) holds the entire refrigerant charge after system pump down. The receiver in a refrigeration system acts as a storage tank for the refrigerant charge. After the system is pumped down, the receiver holds the entire refrigerant charge, ensuring it can be reintroduced into the system when needed. This is an essential function, as it prevents the loss of refrigerant and allows the system to be serviced or repaired without completely discharging the refrigerant. The other options are incorrect because they do not accurately describe the primary function of the receiver. Option A is the role of the accumulator, Option B is the role of the superheater, and Option D is the role of the filter-drier.
