The chemistry of air conditioning
Today’s Video of the Day from the American Chemical Society (ACS) describes the science behind air conditioning.
Just like refrigeration, air conditioners use a fluid called a refrigerant that constantly shifts between a gas and liquid state to absorb heat and carry it outside where it is released. A compressor provides the pressure that is needed to condense the refrigerant into a liquid over and over again, so that it can continue to move heat outdoors.
