Refrigeration Accessories

What is the purpose of a filter drier in a refrigeration system?

• To regulate the flow of oil in the compressor

• To remove water and contaminants from the refrigerant

• To increase the temperature of the refrigerant

• To reduce the pressure in the system

What is the function of a solenoid valve in a refrigeration system?

• Control the flow of refrigerant

• Increase the humidity in the system

• Regulate the compressor speed

• Monitor the oil level in the system

Where is a liquid receiver located in a refrigeration system?

• Between the condenser and the expansion device

• Next to the compressor

• Inside the evaporator coil

• At the end of the refrigerant line

What is the purpose of a suction accumulator in a refrigeration system?

• Control the temperature of the refrigerant

• Prevent liquid flooding and slugging in the compressor

• Increase the pressure in the system

• Regulate the flow of refrigerant

Why is a service valve important in a refrigeration system?

• Monitors the pressure in the condenser

• Controls the temperature inside the evaporator

• Regulates the oil flow in the system

• Allows convenient access to the refrigerant for troubleshooting

What is the function of an oil separator in a refrigeration system?

• Increases the efficiency of the condenser

• Separates oil from the refrigerant and sends it back to the compressor

• Controls the flow of refrigerant

• Reduces the temperature of the refrigerant

Why is a relief valve necessary in a refrigeration system?

• Regulates the flow of oil in the compressor

• Increases the cooling capacity of the system

• Controls the humidity level in the system

• Prevents the refrigeration vessel from rupturing under high pressures

What is the purpose of a vibration eliminator in a refrigeration system?

• Regulates the flow of refrigerant

• Increases the pressure in the condenser

• Absorbs compressor vibrations and minimizes noise transmission

• Controls the temperature inside the evaporator

What does a sight glass/moisture indicator allow a technician to do?

• Directly observe the state and condition of the refrigerant

• Adjust the compressor speed

• Increase the oil flow in the system

• Monitor the temperature inside the evaporator

Which of the following is NOT a common refrigeration accessory?

• Oil separator

• Solenoid valve

• Filter drier

• Expansion valve
