Refrigeration Systems Step 1: the refrigeration fluid is pumped into the cooling unit where it is forced through a tiny opening to evaporate and draw heat Step 2: The gas is then directed outside the cooling unit to the coils located in the back.

Refrigeration systems (continued) Step 3:As the gas condenses into the coils, heat is given off to the surrounding air. Step 4: The liquid returns to the cooling unit and the cycle continues.

A motor pumps the fluid through the system, where it enters the processes of evaporization and condensation A cooling system simply pumps heat from one part of the unit to the other
