Understanding the fundamental process behind all HVACR systems
Key Concept
Refrigeration is NOT about making things cold - it's about removing unwanted heat from one location and moving it to another location where it doesn't matter.
Four Main Components
Compressor
Condenser
Metering Device
Evaporator
Continuous Cycle
Refrigerant flows continuously through all four components, changing state from gas to liquid and back to gas, while pressure and temperature vary at each stage.
