The birth of domestic refrigeration
The early 20th century saw the introduction of household refrigerators, marking a pivotal moment in refrigeration history. The Kelvinator, introduced in 1913, and the General Electric “Monitor-Top,” released in the 1920s, were among the first commercially successful refrigerators. These early models used toxic refrigerants like sulfur dioxide and methyl formate.
Freon and household refrigeration revolution
In the 1930s, the introduction of non-toxic and non-flammable refrigerants, such as Freon (developed by Thomas Midgley Jr. and Charles Franklin Kettering), revolutionized household refrigeration. This breakthrough made refrigerators safer, more efficient, and widely accessible to households around the world.
Smart fridges and IoT integration
Fast forward to the 21st century, and refrigeration technology has reached unprecedented heights. Smart fridges, equipped with IoT capabilities, have become the epitome of convenience and efficiency. These intelligent appliances can connect to the internet, allowing users to monitor and control their refrigerators remotely. They feature touchscreens, cameras, and sensors that provide real-time information about food inventory, expiration dates, and even suggest recipes based on available ingredients.
