Overview

The refrigeration cycle is a vital process that allows us to cool spaces and preserve food by removing heat from designated areas. It involves four main processes: compression, condensation, expansion, and evaporation, each playing a crucial role in the cycle's efficiency. Understanding the componen...

Key Terms

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

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

Compressor
A device that compresses the refrigerant, raising its pressure and temperature.

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

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

Example: In a refrigerator, the condenser is usually located at the back.

Evaporator
A component where the refrigerant absorbs heat and evaporates into gas.

Example: The evaporator coils are found inside the refrigerator.

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

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

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

Example: Thermodynamics principles are applied in designing refrigeration systems.
