Refrigeration Cycle Quiz

What is the primary function of the compressor in a refrigeration cycle?

• To lower the pressure of the refrigerant

• To increase the temperature and pressure of the refrigerant

• To cool down the refrigerant

• To remove moisture from the refrigerant

Which component of the refrigeration cycle is responsible for absorbing heat from the refrigerated space?

• Compressor

• Condenser

• Expansion valve

• Evaporator

What happens to the refrigerant in the condenser?

• It evaporates into a gas

• It condenses into a liquid

• It expands into a gas

• It turns into ice

In the expansion valve, what change occurs to the refrigerant?

• It changes from a high-pressure liquid to a low-pressure liquid

• It changes from a gas to a liquid

• It changes from a low-pressure liquid to a high-pressure liquid

• It increases in temperature

What is the role of the evaporator in the refrigeration cycle?

• To raise the pressure of the refrigerant

• To condense the refrigerant into a liquid

• To absorb heat and evaporate the refrigerant

• To remove air from the refrigerant

Which phase of the refrigerant is present when it leaves the compressor?

• Low-pressure liquid

• High-pressure liquid

• Low-pressure gas

• High-pressure gas

What happens to the temperature of the refrigerant as it passes through the expansion valve?

• It increases

• It stays the same

• It decreases

• It turns into a solid

Where does the refrigerant release the heat it has absorbed from the refrigerated space?

• Evaporator

• Compressor

• Condenser

• Expansion valve

Which thermodynamic principle explains the refrigerant's ability to absorb heat in the evaporator?

• Boyle's Law

• First Law of Thermodynamics

• Second Law of Thermodynamics

• Charles's Law

Which type of refrigerant state enters the expansion valve?

• High-pressure gas

• Low-pressure gas

• High-pressure liquid

• Low-pressure liquid
