The history of the refrigerator is shrouded in legends and technical disputes, since the path from the idea of preserving cold to mass production took more than half a century. If we answer the question of where the refrigerator was invented, then the geographic starting point should be the United States of America and France at the beginning of the 19th century, where engineers independently experimented with artificial refrigeration. It was in the USA in 1803 that Thomas Moore patented the first glacier, and a little later, in 1834, an American doctor Jacob Perkins created the first working vapor compression machine.
However, we must not forget about the contribution of European scientists, in particular the Frenchman Ferdinand Carré, whose absorption plants became prototypes for many household models of the early 20th century. The development of technology proceeded in leaps and bounds: from bulky and dangerous installations that used toxic sulfuric ether to safe home appliances. Refrigeration equipment has come a long way before becoming an integral part of every kitchen.
It is important to understand that the invention of the refrigerator was not a one-time thing an act of insight, but a long process of evolution of engineering thought. Different countries contributed to the improvement of refrigerants, compressors and control systems. It was in the USA, in the state of Maryland, in 1803 that the first commercially successful prototype of a “refrigeration room” was created.
Predecessors: from glaciers to the first cars
Before the advent of electricity, people used natural ice for food preservation. In the cold season, ice was harvested from reservoirs and stored in special underground structures - glaciers. This technology was known in Ancient Persia and China, but in Europe and America it became widespread in the 18th-19th centuries. The glacier business flourished: ice was transported from north to south, packed in sawdust and straw to minimize melting.
The first attempts to create artificial cold were associated with chemical reactions. Scientists have noticed that some salts, when dissolved in water, greatly cool the solution. However, this method did not allow obtaining stable and long-lasting cold. The real breakthrough came when engineers turned their attention to the properties of gases. It turned out that when a compressed gas suddenly expands or when liquids evaporate, the ambient temperature drops.
⚠️ Attention: Early experimental installations often used flammable or toxic substances such as ether or ammonia. Working with them at home was deadly, so for a long time refrigerators remained the province of laboratories and industrial enterprises.
The key figures of this period were:
- 🧊 William Cullen —a Scottish doctor who in 1756 demonstrated the principle of artificial refrigeration by evaporating diethyl ether in a vacuum.
- ❄️ Oliver Evans is an American who in 1805 described the concept of a closed cycle using a compressor, although he never built a working model.
- ⚙️ Jacob Perkins - put Evans' ideas into practice and received the first patent for a vapor compression cycle.
American breakthrough: Jacob Perkins' patent
Many technology historians consider 1834 to be the official date of birth of the refrigerator. It was then that a machine operating on the principle of compression and expansion of steam was demonstrated in London (although Perkins was an American). etherwas used as a refrigerant. The device consisted of a compressor, condenser, expansion valve and evaporator - the same components that are used in modern models.
Perkins' machine was bulky and required constant manual control or a steam engine, which made it unsuitable for domestic use. Nevertheless, the operating principle was fundamentally correct. Unlike absorption systems, which appeared later, compression machines were more efficient, but required reliable sources of energy, which were not yet available in homes at that time.
The development of technology in the United States paralleled the development of railway transport. There is an urgent need for transportation of meat and perishable products over long distances. This stimulated engineers to create more powerful and reliable industrial refrigeration units. refrigerated cars for transporting meat and perishable products over long distances. This stimulated engineers to create more powerful and reliable industrial refrigeration units.
Why did they stop using ether?
Ether has high volatility and an extremely low ignition temperature. Any spark in the compressor could lead to an explosion, so at the end of the 19th century it was replaced with safer, although toxic, refrigerants like ammonia and sulfur dioxide.
European contribution: Carré absorption refrigerators
While compressors were being improved in America, an engineer in France Ferdinand Carré went a different route. In 1858, he introduced the absorption refrigerator, which did not require a mechanical compressor. In this system, circulation of the refrigerant was ensured by heating a solution of ammonia in water. This was a revolutionary invention, since the source of energy could be an ordinary gas lamp or even a kerosene burner.
Carré's absorption refrigerators were the first devices that began to penetrate rich homes and restaurants. They operated silently because they had no moving mechanical parts (except for the fan in later models). However, their efficiency (efficiency) was significantly lower than that of compression analogues, and the cooling process took a lot of time.
Comparison of technologies of that time shows a variety of approaches:
| Characteristics | Compression (Perkins) | Absorptive (Carre) | Ice cabinets |
|---|---|---|---|
| Energy source | Steam engine / Electricity | Gas / Kerosene / Heat | Natural ice |
| Noise | High | Silent | Silent |
| Efficiency | High | Low | Depends on ice |
| Safety | Risk of explosion (ether) | Risk of poisoning (ammonia) | Safe |
Despite Carré's success, by the beginning of the 20th century, with the spread of electricity, the compression circuit again came to the fore due to its power and ability to maintain consistently low temperatures.
The era of electricity and the emergence of household models
The real revolution occurred at the beginning of the 20th century century when electricity became available in homes. In 1911, General Electric introduced the first electric refrigerator for home use - DOMELRE (Domestic Electric Refrigerator). It was still dangerous: the refrigerant was sulfur dioxide, which when leaked formed sulfuric acid, and the compressor was located in the basement of the house due to noise and vibration.
Mass production began in the 1920s. Brands appeared that still exist, for example Frigidaire i Kelvinator. Engineers were looking for a replacement for toxic refrigerants. In 1928, Thomas Midgley Jr. synthesized Freon (R-12), a gas that was nonflammable, nontoxic, and ideal for household compressors. This ushered in the golden age of refrigeration.
By the 1930s, the refrigerator ceased to be a luxury and became a necessity in the United States and Europe. The design was improved: thermostats, automatic defrosting (in later models) and improved thermal insulation appeared.
Soviet experience: from “Christor” to “Biryusa”
In the Soviet Union, the history of the refrigerator developed as usual. The first experiments were carried out back in the 1930s at the Kharkov Kompressor plant, where, under the leadership of engineer K.I. Shendal created the first Soviet compressor. However, mass production of household refrigerators began only after the Great Patriotic War.
Legendary ZIS-KH (later “Moscow”), released in 1951, became a symbol of post-war reconstruction. It was a copy of the American General Electric refrigerator, the drawings of which were received under Lend-Lease. It was large, heavy, and had an external compressor, but it worked reliably for decades. Later, more compact models appeared, such as Saratov and Biryusa.
A feature of Soviet refrigerators was their maintainability and “indestructibility”. The simple design allowed craftsmen to change compressors and thermostats at home. Absorption refrigerators, such as “Sever” or “Morozko”, were also popular, especially in holiday villages where electricity was often cut off or there was no 220V network (some models ran on gas).
⚠️ Attention: Old Soviet refrigerators use thermal insulation made of glass wool, which can settle over time, impairing cold retention. Also, models before the 1970s often used flammable refrigerant R-600 (isobutane) or toxic R-12, which requires caution during disposal.
Modern technologies and environmental standards
By the end of the 20th century, humanity was faced with a new problem: freons, which were considered safe for humans, were destroying the ozone layer Earth. International agreements (the Montreal Protocol) were adopted that banned the use of chlorofluorocarbons (CFCs). Engineers had to change the chemical composition of refrigerants again.
Today, refrigerators use R-134a and R-600a (isobutane) gases. The latter is especially interesting: it is a natural gas that does not destroy ozone and has excellent refrigeration properties, but it is explosive when concentrated in air. Therefore, modern requirements for tightness systems are extremely high.
The evolution of refrigerators continues:
- 📱 Smart functions — control via Wi-Fi, cameras inside, product recognition.
- 💨 No Frost —automatic defrosting systems, eliminating the need to chip ice.
- 🌿 Eco modes —optimization of compressor operation to minimize energy consumption (class A+++).

Frequently asked questions (FAQ)
Who exactly is considered the inventor of the refrigerator?
There is no single inventor, but the father of the modern refrigeration cycle is often called Jacob Perkins (1834), who created the first vapor compression machine. However, the contribution of Carré (absorption) and later engineers who created safe household models is also invaluable.
Why were the first refrigerators dangerous?
Flammable substances (ether) or toxic gases (ammonia, sulfur dioxide) were used as refrigerants. A leak of such substances in a confined kitchen space could lead to a fire, explosion, or poisoning of residents.
When did refrigerators become safe for the home?
The mass distribution of safe models began in the 1930s after the invention of freon. However, the problem of safety and environmental friendliness is still being finally solved with the transition to isobutane (R-600a).
What is the difference between a compressor and an absorption refrigerator?
A compressor uses a mechanical pump to compress gas (noisy, but effective). Absorption uses heating of an ammonia solution (it works silently, can be powered by gas, but is less efficient and takes longer to cool).
The history of the creation of the refrigerator is a striking example how humanity's need to preserve food moved science forward. From simple glaciers to smart electronic systems with artificial intelligence - this journey took less than two hundred years, radically changing our way of life.
