Who invented the refrigerator: from ancient glaciers to the first household ones models

A refrigerator today is an indispensable household appliance, without which it is difficult to imagine a modern kitchen. But few people think about how this invention appeared and who was at its origins. The history of refrigeration technology goes back centuries: from primitive glaciers of antiquity to complex systems with compressors and freon. In this article we will understand who really invented the refrigeratorwhat stages cooling technology has gone through and why the first household models became a revolution for households.

Spoiler: the answer to the question is not as clear-cut as it seems. The fact is that the refrigerator in its modern form is the result of the work of dozens of inventors from different countries. Someone proposed a theoretical basis, someone designed the first working prototype, and someone adapted the technology for the mass consumer. We will trace the entire path: from experiments with ice in Ancient Egypt to mass production General Electric and Frigidaire in the 20th century.

We will pay special attention to key figures - those whose ideas changed the world. You will learn why William Cullen is considered the “father” of artificial refrigeration, how Jacob Perkins built the first refrigeration unit, and why Carl von Linde revolutionized the industrial production of ice. Let's also look at the myths: is it true that Einstein invented the refrigerator, and why Soviet engineers contributed to the development of technology.

Ancient predecessors: how people stored food before the invention of the refrigerator

Long before the advent of electric refrigerators, humanity had already solved the problem of preserving food. Archaeological finds confirm: the first “refrigeration chambers” appeared in 3000 BC Mesopotamia and Ancient Egypt. People used natural sources of cold - ice and snow - to slow down the spoilage of food.

The easiest way is glaciers (or pits for storing ice). They were dug into the ground, insulated with straw or clay, and filled with snow and ice in winter. In summer, such a “refrigerator” could maintain a low temperature for up to several months. In Persia, for example, special yachchal towers were built, where ice was stored all year round thanks to a unique ventilation system.

• 🏺 Ancient Egypt (2000 BC): clay jugs with porous walls in which food was placed and lowered into water - evaporation created a cooling effect.
• ❄️ China (1000 BC): the first glaciers for storing ice cut down from lakes in winter. Ice was transported over long distances for the nobility.
• 🏛️ Ancient Rome (500 BC): cellars with wells where snow brought from the Alps was stored. Emperor Nero allegedly spent fortunes on delivering ice to cool drinks.

Interestingly, in the Middle Ages in Europe, glaciers became a luxury: only rich families could afford to store ice in special cellars. And in Russia, until the 19th century, peasants used ice pits deep wells filled with snow in winter and covered with straw. Such “refrigerators” kept the temperature around +2…+4°C even in July.

The first steps towards artificial refrigeration: scientific discoveries of the 18th–19th centuries

The turning point in the history of refrigerators came when scientists began to study physical principles of refrigeration. In the 18th century, several key discoveries were made that laid the foundation for future inventions:

1. 1748: A Scottish chemist William Cullen first demonstrated artificial refrigeration by evaporating ether in a vacuum. In his experiment, the temperature dropped to -12°C, which became a sensation.
2. 1805: American inventor Oliver Evans described a project for a refrigeration machine running on compressed ether. However, he never built it.
3. 1834: the British Jacob Perkins received a patent for the first compression refrigeration unit. His machine used liquid ammonia and could produce ice, but was too bulky for domestic use.

The main problem of early refrigeration machines — toxicity of refrigerants. Ammonia, ether and sulfur dioxide, which were then used, were dangerous to health. In addition, the systems required constant maintenance and took up an entire room. However, these inventions proved: artificial refrigeration is possible without natural ice.

It was Jacob Perkins who is often called the “inventor of the refrigerator” in textbooks, although his machine was not a household one. His 1834 patent was the first documentary evidence of the performance of the compression cycle - the principle that underlies 90% of modern refrigerators.

The Industrial Revolution and Refrigeration Machines: The Contribution of Carl von Linde

The real breakthrough occurred in the second half of the 19th century, when a German engineer Carl von Linde developed industrial refrigeration plant. His system, patented in 1876 yearused ammonia compressor and became the first truly efficient machine for making ice on a large scale.

Linde not only improved the design, but also founded the company Linde AGwhich is still a leader in the production of refrigeration equipment. Its installations were used in breweries, meat processing plants and medical institutions. For example, thanks to his invention, it became possible to transport meat from Argentina to Europe without spoilage - this revolutionized world trade.

• ⚙️ 1871: Linde creates the first closed-cycle refrigeration machine (ammonia is compressed, cooled, evaporated).
• 🍺 1873: brewery Spaten-Franziskaner-Bräu in Munich becomes Linde's first client - his machine cools the fermentation tanks.
• 🚢 1876: the first refrigerated ship "Frigorifique" transports frozen meat from Buenos Aires to Rouen.

However, household refrigerators were still a dream. Linde's industrial installations were too large and expensive for home use. In addition, ammonia remained dangerous: leaks could lead to poisoning. The solution to this problem was found only in the 20th century.

The first household refrigerators: who released a serial model for the home

The transition from industrial installations to household refrigerators occurred in 1910–1920s. The main merit here belongs to American companies General Electric (GE) i Frigidaire, which for the first time launched mass production of compact refrigerators.

The first household refrigerator called DOMELRE (DOmestic ELectric REfrigerator) was released by the company General Electric v 1911. It cost $1000 (about $30 000 in today's money!) and was available only to wealthy families. The device operated on toxic gas - sulfur dioxide (SO₂), and therefore required careful handling.

The breakthrough occurred in 1918when Frigidaire (division General Motors) introduced the model with automatic control. The refrigerator itself maintained the set temperature, which was innovative. By 1923 the company sold more than 200,000 units, and the price fell to $200–300.

K 1930s refrigerators have become safer: instead of sulfur dioxide they began to use Freon-12 (CCl₂F₂) - non-toxic and non-flammable refrigerant. This invention belongs to an American chemist Thomas Midgleywho worked for the company DuPont. Freon refrigerators quickly replaced dangerous models and became the standard for the next 50 years.

Why the first were refrigerators so expensive?

The price consisted of several factors:

1. Manual assembly —each device was made almost by hand, without a conveyor.

2. Expensive materials —copper for tubes, steel for the body, glass thermal insulation.

3. Dangerous refrigerants —systems with SO₂ required enhanced sealing and control.

4. Low demand —the first models were bought only by the rich, so manufacturers could not reduce the price due to scale.

5. Electricity —not all houses in the 1910s–1920s were electrified, which narrowed the market.

Soviet trace: how refrigerators were created in the USSR

In the Soviet Union, the development of refrigeration technology went its own way. If in the USA and Europe household refrigerators became widespread, then in the USSR their serial production began only after the war. The first domestic models appeared in 1930s, then in the USSR their serial production began only after the war. The first domestic models appeared in 1950s, and their production was associated with the name of the designer Sergei Alekseevich Lebedev.

In 1951 on Borets Refrigeration Engineering Plant (Serpukhov) they released the first Soviet household refrigerator - "Mir". It worked for ammonia, had a volume of 160 liters and cost 2500 rubles (the average salary then was about 600 rubles). Despite the high price, the demand was enormous: people stood in queues for years.

• ❄️ "Mir" (1951): the first Soviet refrigerator, absorption type, manual defrosting.
• 🍦 "Saratov" (1959): compression refrigerator with freezer, produced in Saratov factory.
• ⚡ "ZIL-Moskva" (1962): legendary model with automatic defrosting, a symbol of Soviet life.
• 🏆 "Biryusa" (1960s): refrigerators from Krasnoyarsk, known for reliability and simplicity.

It is interesting that Soviet engineers contributed to the global refrigeration industry. For example, in 1960s the USSR developed the first refrigerators with the No Frost system (automatic defrosting), which were later improved abroad. And the model "Oka-6" (1970s) became one of the most popular in the country due to its compactness and efficiency.

Myths and legends: is it true that Einstein invented the refrigerator?

On the Internet there is often a statement that Albert Einstein he invented the refrigerator. This is a half-truth. Indeed, the great physicist, together with his colleague, received a patent for (US patent No. 1781541). However, their invention did not become widespread. Leo Szilard received a patent for absorption refrigerator V 1930 (US Patent No. 1781541). However, their invention did not become widespread.

Einstein and Szilard proposed a system working on ammonia, water and butane, without moving parts. The main advantage is lack of a compressor, which made the refrigerator silent and reliable. But there were also disadvantages:

• ⚠️ Complexity of production —the technology required high-precision parts.
• ⚠️ Low efficiency —cooling took longer time than compression models.
• ⚠️ Competition —by the 1930s, freon refrigerators already dominated the market.

Einstein's patent remained an experimental project. However, his later ideas were used in gas refrigerators (for example, in camping models) where electricity is not available. Today, the original copy of Einstein's refrigerator is kept in The German Museum in Munich.

Another common myth is that the refrigerator was invented. Thomas Edison. In fact, Edison had nothing to do with refrigeration, although his companies produced electric motors for early models. But Nikola Tesla he really worked on improving electrical systems for refrigerators, but did not receive patents for the devices themselves.

Evolution after the war: from freon to inverter compressors

After World War II, refrigerators became a mass product. Key development milestones:

1. 1950s: emergence two-chamber refrigerators (separate zones for cooling and freezing). The company Whirlpool was the first to release a model with a freezer on top.
2. 1960s: distribution automatic defrosting (system Frost Free). There was no longer any need to manually chip the ice!
3. 1980s: transition to more environmentally friendly refrigerants due to the ban on freon (Montreal Protocol, 1987). It was replaced by R-134a and other ozone-safe gases.
4. 1990s: emergence inverter compressors (company Hitachi). They consumed 30–50% less energy and operated almost silently.
5. 2000s: integration smart technologies — Wi-Fi modules, touch panels, cameras inside the chamber (for example, Samsung Family Hub).

Today refrigerators have become not just household appliances, but high-tech devices. Modern models are equipped with:

• 🤖 Artificial intelligence (habit analysis user).
• 🌿 Systems BioFresh for long-term storage of vegetables and fruits.
• 🔋 Solar batteries (for autonomous operation).
• 📱 Mobile applications for remote control.
