Refrigerators are important in our daily lives. They help keep our food fresh and safe to eat. But have you ever wondered when refrigerators were invented? Let’s take a journey through time and find out!
Early Attempts at Cooling
Before refrigerators, people had to find other ways to keep food cool. Many used ice and snow. These were natural ways to preserve food.
In ancient times, people stored ice in cellars. They also used caves to keep food cool. These methods worked, but they were not very convenient.
The First Artificial Refrigeration
The first artificial refrigeration was invented in the 18th century. Dr. William Cullen, a Scottish scientist, made this discovery. In 1755, he demonstrated how to create ice using a pump. This was the beginning of artificial refrigeration.
In 1805, an American inventor named Oliver Evans designed a refrigerator. His design used vapor instead of liquid. However, he did not build it.
Jacob Perkins and the First Working Refrigerator
In 1834, Jacob Perkins, an American, built the first working refrigerator. He used Evans’ design. Perkins’ refrigerator used ether in a vapor compression cycle. This was a big step forward in refrigeration technology.
John Gorrie and Medical Refrigeration
In the 1840s, Dr. John Gorrie, an American physician, made another important discovery. He built a refrigerator to cool the air for his patients. His invention helped treat patients with yellow fever.
Gorrie’s refrigerator used a compressor to create ice. This was the first time refrigeration was used for medical purposes.
Carl von Linde and Modern Refrigeration
In 1876, a German engineer named Carl von Linde improved the refrigerator. He developed a new compressor. This made refrigerators more efficient.
Von Linde’s work led to the widespread use of refrigeration. It changed the way people stored and transported food.
The Introduction of Electric Refrigerators
In the early 20th century, electric refrigerators were invented. In 1913, Fred W. Wolf invented the first electric refrigerator for home use. It was called the “DOMELRE,” short for Domestic Electric Refrigerator.
In 1918, the Frigidaire company introduced a refrigerator with a self-contained compressor. This made refrigerators more popular in homes.
Refrigerators in Every Home
By the 1930s, refrigerators became common in households. They replaced iceboxes, which used ice to keep food cool. Refrigerators made life easier for families.
In the 1950s, refrigerators became even more advanced. They included features like automatic defrosting and separate freezer compartments.

Modern Refrigerators
Today, refrigerators are found in almost every home. They come in many shapes and sizes. Some have advanced features like water dispensers and smart technology.
Modern refrigerators are energy-efficient and environmentally friendly. They use less electricity and have better insulation.
The Impact of Refrigerators on Society
Refrigerators have changed the way we live. They help keep our food fresh and safe to eat. This has improved our health and well-being.
Refrigerators also make it easier to store and transport food. This has led to the growth of supermarkets and global food trade.
