Refrigeration always has been closely intertwined with chemistry. In this episode we explore the history of refrigerants, from the first hints of artificial cooling in the mid-1700s, through the invention of the first practical refrigerator 8 decades later. We talk about a variety of refrigerants through the 20th century. Finally we examine some other newer or less-common methods of cooling.
