Final answer:
The refrigeration compressor performs several functions, but maintaining a low pressure in the evaporator is not one of them.
Step-by-step explanation:
The refrigeration compressor performs several functions in a refrigeration system, but maintaining a low pressure in the evaporator is NOT one of them. Here are the functions of the refrigeration compressor: Raises the pressure of the refrigerant: The compressor increases the pressure of the refrigerant gas, which helps in transferring heat to the surrounding environment.
Raises the temperature of the refrigerant: The compressor also increases the temperature of the refrigerant gas by compressing it, which aids in heat transfer. Circulates refrigerant through the system: The compressor circulates the refrigerant throughout the refrigeration system, allowing it to undergo phase changes and absorb or release heat at different points.
Removes energy from the vapor: The compressor removes energy from the refrigerant vapor by compressing it, which facilitates the cooling process. Therefore, the correct answer is (C) Maintains a low pressure in the evaporator.
