In this video, we break down the refrigeration cycle in a simple, practical way for HVAC technicians and students. You’ll learn how refrigerant moves through the compressor, condenser, metering device, and evaporator, what the refrigerant is doing in each part of the system, and how pressure and temperature work together. We also cover saturated, superheated, and subcooled refrigerant, how to use a PT chart, and why superheat and subcooling matter when diagnosing and charging a system.
Whether you’re brand new to HVAC or just want a clearer understanding of the basics, this lesson is designed to make the refrigeration cycle easy to follow and apply in the field.
