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.
2.
FLASHCARD QUESTION
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.
3.
FLASHCARD QUESTION
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.
4.
FLASHCARD QUESTION
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.
5.
FLASHCARD QUESTION
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.
6.
FLASHCARD QUESTION
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.
