Extending the usage of refrigerants in cooling systems (TBD Words) Imagine sitting at home in the middle of July. Now, imagine if that day had a high temperature of over 100 degrees, and a heat index of over 115 degrees. If you are living in the United States, then you are probably imagining yourself sitting in a room with some sort of air conditioning system keeping you cool. That comfort, however, comes at a price. In 1985, it was discovered that chlorofluorocarbons (CFC’s), one of the main refrigerants used in air conditioning systems, played a substantial role in the depletion of the ozone layer (Farman, Gardiner and Shanklin). CFC’s were ultimately banned as a means of refrigeration, which ushered in the next generation of coolant types known as hydrofluorocarbons (HFC’s). Unfortunately, “systems using these HFCs, however, make a moderate contribution to global warming because of their efficiency and low emission rates.” (Sand, Fisher and Baxter, P.E.). While addressing the issue of the ozone layer, HFCs initiated a new set problems themselves, including having an increased Global Warming Potential (GWP). Despite the negative environmental impacts of the past, the use of refrigerants in home cooling systems should continue.
Beginning in the late 1800’s, air conditioning systems have been a part of everyday living. From through-the-window air conditioners to centralized duct systems, nearly every home built in
