Imagine if all the food we ate was stored and shipped in briny sea water? While this might seem gross to us today, just 100 years ago this was the most common method of shipping meat and other perishable food products. Thankfully, technology advanced, and today we have fully functioning refrigerators.
The concept of a refrigerator began in the mid-1700s with a man named William Cullen. Cullen was the first to discover that compressed gas could actually be used to cool the air. Nearly a century later, a man named John Gorrie developed the first functional vapor-compression refrigerator and these quickly became popular with breweries and the meat-packing industry. Eventually J.P. Morgan’s General Electric released the very first commercial refrigerator in 1911 and the rest is now history.
However, these early model refrigerators have very little in common with their modern counterparts. Whereas these older models utilized compressed gases that could kill a human, modern refrigerant doesn’t pose any dangers to humans or the environment. More importantly, modern refrigerators require less electricity and many operate under the Energy Star label.
