Heat Transfer Flashcards
What does the cooling fan do in the heat transfer process?
Blows warm air over the cold evaporator coil.
Example: The cooling fan helps cool down the warm air inside the cab.
How does the Low Pressure Liquid in the evaporator absorb warmer air?
The warmer air in the cab is absorbed by the cold Low Pressure Liquid in the evaporator.
No additional information.
What happens to R134a when its temperature increases above its boiling point?
It evaporates (boils) into a low pressure gas.
No additional information.
What is done to the warmer low pressure gas R134a before it is sent back to the compressor?
It is routed back to the compressor.
No additional information.
What does the compressor do to the low pressure gas in the heat transfer process?
Pressurizes the low pressure gas, which increases heat. It is then routed to the condenser.
No additional information.
What happens to the refrigerant inside the condenser?
It is cooled (releases heat) due to the air flowing over the condenser.
No additional information.
What state does the high pressure gas condense into inside the condenser?
High pressure liquid, and release heat energy.
No additional information.
