Refrigeration Cycle Quiz

The __________________________ is the heart of the vapor-compression refrigeration cycle.

• Compressor

• Evaporator

• Condenser

• Expansion Valve

________________________ -pressure, ______________________ -temperature, superheated refrigerant vapor enters the compressor and is compressed, changing it to a -pressure,________________________ -temperature, superheated vapor.

• High

• High

• Low

• Low

• Medium

It then moves to the __________________________ where some of the heat is removed, and condensing it into a ________________________________.

• Condenser

• Liquid

• Evaporator

• Gas

• Heater

Before it leaves the________________________ as a high-pressure liquid, the liquid refrigerant is ______________________ to a point below the liquid saturation temperature.

• Condenser

• Subcooled

• Evaporator

• Superheated

• Compressor

It then flows to the________________________ or ________________________ device as a high-pressure, subcooled liquid.

• Expansion valve

• Metering

• Compressor

• Evaporator

• Condenser

As the refrigerant flows through the metering device, the pressure of the__________________ is reduced, causing a small percentage of the liquid ______________________ to a vapor (flash-gas), lowering the temperature of the remaining refrigerant to its____________________ temperature.

• Saturation

• Evaporates

• Condenses

• Refrigerant

• Compressor

The low-pressure, low-temperature refrigerant flows into the ________________________ as a low-temperature saturated refrigerant.

• Evaporator

• Condenser

• Compressor

• Expansion Valve

As the refrigerant absorbs heat, it evaporates into a low-temperature vapor. This______________________ process is referred to as direct expansion.

• Evaporation

• Condensation

• Sublimation

• Deposition

During this process, the refrigerant vapor is________________________ above its saturation temperature and then enters the __________________________.

• Superheated and Condenser

• Subcooled and Evaporator

• Superheated and Compressor

• Condensed and Expansion Valve

From the ________________________, refrigerant enters the ____________________ as a low-pressure, low temperature, ____________________ to repeat the cycle.

• evaporator, compressor, gas

• condenser, expansion valve, liquid

• compressor, evaporator, liquid

• expansion valve, condenser, gas
