Basic Refrigeration Cycle
All air conditioning and refrigeration systems are designed to control and contain a circulating refrigerant. The basic refrigeration cycle absorbs unwanted heat at one location and carries it to another location where it can be discarded. Refrigerants are the vital working fluids in any refrigeration system. Refrigerant will absorb heat by evaporation (changing from a liquid to a gas). Then, they release the heat through condensation (changing a gas back to a liquid). In a proper operating system, the refrigerant will not break down, wear out, or become lost unless there is a leak.
A good understanding of the basic refrigeration system is important to your success as a technician since “complicated” systems are simply basic systems with one or more components added to make them more efficient, versatile, or serviceable. You must learn the refrigeration cycle well.
