Refrigeration is the process of removing heat from an enclosed space generally by evaporating and condensing a substance (usually a CFC gas).
Almost all have been phased out due to harmful effects to either the surrounding area or the o-zone layer.
Cooling both a freezer and a refrigerator involves the coolant previously mentioned (usually Freon), getting put through a short process.
When a special thermometer detects that the fridge has reached the proper temperature, it simply shuts off the motor and the refrigeration cycle is halted.
If a temperature is set on a refrigerator, the cycle just continues until the desired temperature is reached.
