Refrigeration Cycle Explained

This course provides a comprehensive introduction to the refrigeration cycle and explains how vapor compression systems remove heat to provide continuous cooling. Widely used in marine refrigeration, HVAC systems, industrial cooling, and domestic appliances, the refrigeration cycle is one of the most important thermodynamic processes in modern engineering.

You'll begin by learning the difference between the refrigeration cycle and the vapor compression cycle, including why heat pumps also use vapor compression without being refrigeration systems.

The course then examines the four essential components of a vapor compression refrigeration system: the compressor, condenser, expansion valve, and evaporator, and explains how refrigerant continuously circulates through these components in a closed loop. You'll follow the refrigerant through each stage of the cycle while learning how pressure, temperature, and phase changes enable efficient heat transfer.

By the end of this course, you'll understand how refrigeration systems extract heat from a cooled space, reject it to the surrounding environment, and maintain continuous cooling through the vapor compression process.
