  1. The Inner Workings of Old and Modern Refrigerators Eric Abercrombie Levi Algozino E-Design 100 Section 9 Pennsylvania State University http://upload.wikimedia.org/wikipedia/commons/3/36/ExpensiveRefrigerators.JPG

  2. Refrigeration is the process of removing heat from an enclosed space generally by evaporating and condensing a substance (usually a CFC gas). http://firstcoastac.com/faq/freon/

  3. Several Types of Gases have been used in refrigeration systems as chemists discover more efficient systems. Almost all have been phased out due to harmful effects to either the surrounding area or the o-zone layer. http://upload.wikimedia.org/wikipedia/commons/thumb/3/30/Methyl_Chloride.svg/261px-Methyl_Chloride.svg.png http://www.gcsescience.com/Ammonia-Molecule.gif http://upload.wikimedia.org/wikipedia/commons/thumb/3/34/Sulfur_dioxide.svg/467px-Sulfur_dioxide.svg.png

  4. Cooling both a freezer and a refrigerator involves the coolant previously mentioned (usually Freon), getting put through a short process. • 1: Compression • 2: Release of heat • 3: Expansion • 4: Cooling of unit • 5: Back to compression http://www.realsimple.com/food-recipes/tools-products/appliances/how-does-refrigerator-work-00100000087962/index.html

  5. The interior refrigeration system Heat absorbed Substance vaporized Substance liquefied http://www.energyquest.ca.gov/how_it_works/refrigerator.html

  6. 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. http://www.tmchallcrest.com/fridge-freezer-indicators.php
