Refrigeration Cycle Flashcard

Front

What is the refrigeration cycle?

Back

The refrigeration cycle is a thermodynamic process that removes heat from a designated area to lower its temperature, using a refrigerant that circulates through various components including the evaporator, compressor, condenser, and expansion valve.

Front

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

Back

The evaporator absorbs heat from the environment, causing the refrigerant to evaporate and turn into a gas, which cools the surrounding area.

Front

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

Back

The compressor increases the pressure of the refrigerant gas, allowing it to flow through the system and facilitating the heat exchange process.

Front

What does the condenser do in the refrigeration cycle?

Back

The condenser cools and condenses the refrigerant gas back into a liquid by rejecting heat to the environment.

Front

What is the purpose of the expansion valve in the refrigeration cycle?

Back

The expansion valve reduces the pressure of the liquid refrigerant, allowing it to expand and cool before entering the evaporator.

Front

How does the refrigeration cycle maintain a low temperature?

Back

By continuously circulating the refrigerant through the system, absorbing heat from the area to be cooled and rejecting it outside.

Front

What is a refrigerant?

Back

A refrigerant is a substance used in the refrigeration cycle that absorbs and releases heat as it changes from liquid to gas and back.

Front

What happens to the refrigerant in the evaporator?

Back

In the evaporator, the refrigerant absorbs heat and evaporates into a gas.

Front

What is the significance of pressure difference in the refrigeration cycle?

Back

The pressure difference created by the compressor allows the refrigerant to flow through the system, facilitating heat transfer.

Front

Where is the condenser typically located in a refrigeration system?

Back

The condenser is usually located outdoors, where it can reject heat to the outside environment.
