Final answer:
The initial charge of a refrigeration system is typically added to the low-pressure side, which is true (A). This is part of the necessary steps in operating the refrigeration cycle, beginning with the compression of refrigerant gas.
Step-by-step explanation:
When charging a refrigeration system, the statement 'the initial charge is added to the low-pressure side of the system' is typically True. This process involves adding a refrigerant into the system which is in a low-pressure, gaseous state. The low-pressure side of a refrigeration system is where the refrigerant is in a state that makes it easier to introduce new refrigerant without disrupting the system's operation.
A refrigeration cycle begins with the electrically driven compressor, which compresses the low-pressure gas, raising its temperature and pressure, and sends it through the condenser coils. After the refrigerant condenses into a liquid by losing its heat to the surroundings, it moves through an expansion valve and returns back at a lower temperature to absorb the heat from the inside of the refrigerator, completing the cycle.
