notes
We will now review the main concepts that were covered in this clinic reagrding 
the vapor-compression refrigeration cycle.
Period One introduced the concept of heat and how it is transferred from one 
substance to another.
Recall that heat is a form of energy and can vary in both quantity and intensity 
(temperature). Heat energy cannot be destroyed, however, it can be transferred 
to another substance. Heat flows from a higher temperature substance to a 
lower temperature substance.
Refrigeration is a method of removing heat.
