Notable inventors Benjamin Franklin and John Hadley also conducted experiments with innovative methods of cooling using volatile liquids. These groundbreaking experiments and inventions contributed to advancements in the field of refrigeration.
In 1805, American inventor Oliver Evans designed the blueprint for the first refrigeration machine, although he didn't physically construct a model. It wasn't until 1834 that Jacob Perkins built the first practical refrigerating machine based on Evans' design, which utilized a vapor compression cycle to achieve cooling temperatures.
1834 marked the creation of the first functional vapor-compression refrigeration system.
Throughout the 1900s, commercial refrigerators became highly important in various industries, especially in meat-packing. Due to their large size and high cost, early refrigerators were primarily used in commercial settings. In 1870, S. Liebmann's Sons installed the initial commercial refrigerator in a brewery in Brooklyn, and within two decades, almost every major brewery followed suit.
This mechanical refrigeration method proved to be a game-changer, allowing for convenient storage of a wide range of perishable items, including meat and dairy products, while significantly reducing food spoilage. By the mid-1880s, refrigeration had become a common household appliance.
In 1928, the Coca-Cola company enlisted the help of a sheet-metal manufacturing firm to create a specialized Coke cooler for individual retailers. This innovative design featured an icebox on top to hold full sodas and a slanted rack at the bottom for empty bottles.
Throughout the 20th century, advancements were made to develop lighter, more affordable, and easily accessible commercial refrigeration systems for various businesses, including supermarkets and restaurants. The glass-fronted beverage cooler predominantly serves as a commercial refrigerator.
