Refrigeration Cycle Flashcard

Front

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

Back

Compressor

Front

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

Back

Condenser

Front

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

Back

Condenser

Front

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

Back

Expansion valve or Metering

Front

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.

Back

Refrigerant

Front

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

Back

Evaporator

Front

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

Back

Evaporation

Front

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

Back

Superheated and Compressor

Front

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

Front

The ________________________ and ________________________ are the dividing points between the low-pressure and high-pressure sides of the system.
