The invention of the refrigerator has revolutionized the way we store and consume food. From the early days of ice harvesting to the modern refrigerators that we use today, the concept of refrigeration has come a long way. In this article, we will explore the history of refrigeration and find out when the first refrigerator was made.
Early Days of Refrigeration
The concept of refrigeration dates back to ancient civilizations. The ancient Egyptians, for example, used clay pots filled with water and left them in the shade to keep food cool. Similarly, the ancient Greeks and Romans used underground cellars to store food and keep it cool.
In the 17th and 18th centuries, scientists began to experiment with the concept of refrigeration. In 1748, the British scientist William Cullen discovered that evaporation of ether could cool the surrounding air. This discovery led to the development of the first refrigeration machines.
The First Refrigeration Machines
In the early 19th century, the first refrigeration machines were developed. These machines used a combination of evaporation and condensation to cool the air. One of the earliest refrigeration machines was invented by the American inventor Oliver Evans in 1805. Evans’ machine used a compressor to compress air, which then expanded through a valve to cool the surrounding air.
In 1834, the British inventor Jacob Perkins developed a refrigeration machine that used a compressor to compress air, which then expanded through a valve to cool the surrounding air. Perkins’ machine was more efficient than Evans’ machine and was able to cool the air to a temperature of around 40°F (4°C).
The Development of the Refrigerator
In the late 19th century, the development of the refrigerator began. In 1876, the American inventor Carl von Linde developed a refrigeration machine that used a compressor to compress air, which then expanded through a valve to cool the surrounding air. Linde’s machine was more efficient than previous machines and was able to cool the air to a temperature of around 20°F (-7°C).
In the early 20th century, the refrigerator began to take shape. In 1913, the General Electric Company developed the first household refrigerator, which was called the “Monitor-Top” refrigerator. The Monitor-Top refrigerator was a large, freestanding unit that was powered by electricity and had a capacity of around 7.5 cubic feet.
The Modern Refrigerator
Today, the refrigerator is a common household appliance that is used to store food and keep it cool. Modern refrigerators are designed to be more energy-efficient and have a larger capacity than their predecessors. They also have a range of features, such as automatic defrosting and ice makers, that make them more convenient to use.
Some of the key features of modern refrigerators include:
- Energy efficiency: Modern refrigerators are designed to be energy-efficient, which means they use less electricity to cool the air.
- Larger capacity: Modern refrigerators have a larger capacity than their predecessors, which means they can store more food and drinks.
- Automatic defrosting: Many modern refrigerators have an automatic defrosting feature, which means they can defrost themselves without the need for manual intervention.
- Ice makers: Many modern refrigerators have an ice maker, which means they can produce ice cubes without the need for an external ice maker.
- Smart features: Some modern refrigerators have smart features, such as Wi-Fi connectivity and touch screens, which make them more convenient to use.

The first refrigerator was made in 1913 by the General Electric Company. It was called the “Monitor-Top” refrigerator and was a large, freestanding unit that was powered by electricity and had a capacity of around 7.5 cubic feet.
Who invented the first refrigerator?
The invention of the first refrigerator is credited to several individuals, including Oliver Evans, Jacob Perkins, and Carl von Linde. These individuals developed early refrigeration machines that used a combination of evaporation and condensation to cool the air.
What is the history of refrigeration?
The history of refrigeration dates back to ancient civilizations. The concept of refrigeration was first developed in the 17th and 18th centuries, when scientists began to experiment with the concept of evaporation and condensation. The first refrigeration machines were developed in the early 19th century, and the development of the refrigerator began in the late 19th century. The first household refrigerator was developed in 1913.
What are the features of modern refrigerators?
Modern refrigerators have a range of features, including energy efficiency, larger capacity, automatic defrosting, ice makers, and smart features such as Wi-Fi connectivity and touch screens. These features make modern refrigerators more convenient to use and more energy-efficient than their predecessors.
How do refrigerators work?
Refrigerators work by using a refrigerant to cool the air. The refrigerant is pumped through a series of coils and condensers, which cool the air and cause it to expand. The expanded air is then pumped back through the coils and condensers, where it is cooled again and the cycle repeats. This process is known as the “vapor-compression refrigeration cycle.”
