What are the four main components of a basic refrigeration circuit?

• Compressor, Condenser, Expansion Valve, Evaporator

• Solenoid Valve, Heat Exchanger, Filter Drier, Ball Valve

• Condensing Unit, Evaporator, Sight Glass, Copper P-Trap

• Compressor, Heat Exchanger, Solenoid Valve, Evaporator

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

• It lowers the temperature and pressure of the refrigerant gas.

• It raises the temperature and pressure of the refrigerant gas.

• It converts the refrigerant gas into a liquid state.

• It absorbs heat from the surrounding environment.

During condensation in a refrigeration system, what transformation occurs in the condenser?

• The hot gas absorbs heat and turns into a low-pressure gas.

• The hot gas expands and drops in temperature.

• The hot gas releases heat, turning it into a high-pressure liquid.

• The liquid refrigerant evaporates into a gas.

What effect does the expansion valve have on the refrigerant in a refrigeration system?

• It increases the pressure and temperature of the refrigerant.

• It converts the refrigerant from a gas to a liquid.

• It absorbs heat from the refrigerant.

• It lowers the pressure, causing a drop in temperature.

In the evaporator, what happens to the low-pressure liquid-gas?

• It absorbs heat, turning it into a low-pressure gas.

• It releases heat, turning it into a high-pressure liquid.

• It is compressed to increase its temperature and pressure.

• It is filtered to remove impurities.
