Basic Refrigeration topics include: Rrefrigeration units and performance, open air refrigeration system, heat pump, air refrigerator working on reverse carnot and bell coleman cycle.

The basic refrigeration cycle has four main processes:

Compression: The compressor increases the pressure and temperature of refrigerant gas by decreasing its volume.
Condensation: The condenser transfers heat from the refrigerant gas to an external cooling source, such as water or air. The condenser turns the vapor into liquid and absorbs some of the heat.
Expansion: The refrigerant proceeds to the expansion valve, where it expands, losing pressure and heat.
Evaporation: The refrigerant enters the evaporator in a liquid state. The evaporator turns the refrigerant from liquid to gas, absorbing heat and turning the air cold around it. This is where the “conditioning” of the air occurs. 

The other components of the basic refrigeration cycle are: Restriction, Refrigerant.
