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.

Compressor
A device that increases the pressure of the refrigerant, allowing it to circulate through the system.

Example: The compressor is often referred to as the heart of the refrigeration system.

Condenser
A component that cools the refrigerant, allowing it to change from gas to liquid.

Example: In a car's air conditioning, the condenser is usually located at the front of the vehicle.

Evaporator
The part of the system where the refrigerant absorbs heat and evaporates into gas.

Example: In a refrigerator, the evaporator is located inside the cooling compartment.

Thermodynamics
The branch of physics that deals with heat and temperature and their relation to energy and work.

Example: The laws of thermodynamics explain how refrigeration systems operate.

Heat Exchanger
A device that transfers heat between two or more fluids without mixing them.

Example: Heat exchangers are used in both condensers and evaporators.
