Key Terms

Refrigerant
A substance used in refrigeration cycles to absorb and release heat.

Example: Freon is a common refrigerant used in air conditioning systems.

Heat Exchanger
A device that transfers heat between two or more fluids.

Example: In refrigerators, heat exchangers help cool the refrigerant.

Compression
The process of increasing the pressure of a gas, which raises its temperature.

Example: In a refrigerator, the compressor compresses the refrigerant gas.

Condensation
The process where a gas turns into a liquid as it loses heat.

Example: The refrigerant condenses in the condenser coils.

Evaporation
The process where a liquid turns into a gas as it absorbs heat.

Example: The refrigerant evaporates in the evaporator coils, cooling the surrounding area.

Entropy
A measure of disorder or randomness in a system.

Example: In refrigeration, entropy helps explain energy loss during heat transfer.
