2. 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.

3. 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.

4. 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

5. Questions Do you have cooling systems in your home?
If so, what are they?
-When you put your hands near the back of a refrigerator, why do you feel heat coming off of it?
-Why is a refrigerator a “heat pump”?

6. Questions (continued)
-Why is it that on a cool day, when a car is washed hot water will freeze more rapidly than warm water
