History of appearance artificial cold goes back centuries, when humanity was just beginning to think about ways to preserve food. For a long time, the only available method was to use natural ice, which was collected in winter and stored in glaciers, but this solution was seasonal and unreliable. The answer to the question of when the first refrigerator in the world was created is not as clear as it might seem at first glance, since the path from theoretical research to a working household appliance took almost two centuries.
The first experimental installations capable of producing cold artificially appeared at the beginning of the 19th century, but they were bulky, dangerous and accessible only to a select few. Invention of the refrigerator became the result of the work of many scientists, engineers and enthusiasts from different countries who gradually improved gas compression and absorption technologies. It was their work that allowed us today to enjoy fresh food at any time of the year, without depending on the vagaries of nature.
In this article we will examine in detail the key stages in the evolution of refrigeration technology, from the first steam engines to modern smart systems. You will find out who exactly is considered the creator of the first working unit, what substances were used as refrigerants and why the path to mass production was so difficult and thorny.
Prerequisites for the creation of artificial cold
Before the advent of mechanical devices, humanity relied on natural sources of cold for millennia. In ancient times, deep cellars covered with snow and ice were used to store food, and in hot countries they used clay vessels with porous walls, where water evaporated and cooled the contents. However, these methods had a critical drawback: they could not generate cold, but only retained it for a limited time.
The scientific breakthrough began in the 18th century, when researchers began to study the properties of gases and their ability to absorb heat during expansion. Scottish scientist William Cullen first demonstrated the principle of artificial refrigeration in 1748 by creating a vacuum over ethyl ether, causing it to boil and form ice. Although Cullen did not create a practical device, his experiments laid the foundation for future refrigeration cycles. At the beginning of the 19th century, interest in refrigeration increased due to the needs of industry and medicine. American inventor Oliver Evans developed a theoretical model of a machine powered by steam compression in 1805, but never physically built it. His ideas were later implemented by other engineers who proved that a closed cycle of gas compression and expansion could form the basis for refrigeration cycles.

His ideas were later implemented by other engineers who proved that a closed cycle of gas compression and expansion could become the basis for commercial refrigerator.
⚠️ Warning: Early experiments were often conducted using toxic or explosive substances such as ether and ammonia, which made the process extremely risky for researchers of the time.
The first working prototypes: mid-19th century
The mid-19th century was marked by a transition from theories to practice. In 1834, American Jacob Perkins received the first patent for a vapor-compression refrigeration machine. His device, powered by ether, did produce ice, but due to difficulties with sealing and high cost, it was not widely used. Nevertheless, it was Perkins’s machine that is often called the world's first working refrigeratorwhich laid down the principle of operation of modern compressors.
In parallel with Perkins, the American doctor John Gorey worked on the creation of refrigeration units. In 1844, he created an apparatus for cooling the air in a hospital ward to ease the suffering of patients with yellow fever. Gorey's device successfully lowered room temperatures, but like many inventions of the time, it was too bulky and energy-intensive for domestic use.
In the 1850s, French engineer Edmond Carré introduced the absorption refrigerator, which did not require a mechanical compressor. His device used a solution of ammonia in water, which, when heated, released ammonia gas, creating cold as it expanded. This technology turned out to be more reliable and safe, which made it possible to establish industrial ice production in many European countries industrial ice production in many European countries.

Despite advances in industry, household refrigerators were still a dream. The installations required constant maintenance, refueling or a complex mechanical drive, which made them inaccessible to the average person. For a long time, the main consumers of “artificial cold” were restaurants, hospitals and food production.
The era of Karl von Linde and the industrial revolution
A real breakthrough in the history of refrigeration technology occurred thanks to the German engineer Karl von Linde. In 1876, he introduced the first efficient ammonia refrigeration machine, which worked on the principle of vapor compression and was devoid of many of the shortcomings of its predecessors. Von Linde's device was so perfect that its operating principle formed the basis of most modern compressor refrigerators. Von Linde's invention made it possible to establish mass production of ice and refrigerate products on an industrial scale. Breweries, meat processing plants and dairies were the first to appreciate the benefits of the new technology. This led to global changes in logistics: products could be transported over long distances without fear of spoilage, which stimulated the development of international trade. compressor refrigerators.

⚠️ Warning: Ammonia, used in the first von Linde machines, is a toxic gas. Leaks in enclosed spaces could be deadly, so such installations were placed in separate buildings or on the street.
By the end of the 19th century, refrigeration machines began to appear on ships, which made it possible to deliver meat from Australia and Argentina to Europe. This event was called the "Cold Revolution". However, the household was still dominated by an ice cabinet - a wooden box into which imported ice was periodically placed. Electric refrigerator still remained a futuristic concept awaiting the development of electrical engineering.
The appearance of the first household electric refrigerators
The beginning of the 20th century brought with it electrification, which opened up new horizons for household appliances. In 1913, the company General Electric introduced the first home refrigerator with a compressor, designed by engineer Fred Wolf. However, this model was extremely expensive, noisy and required complex maintenance, so demand for it was minimal.
The situation changed in the 1920s, when engineers learned to synthesize safe refrigerants. Until this point, refrigerators used sulfur dioxide, methyl chloride and ammonia, the leakage of which could lead to a fire, explosion or poisoning of residents. The development of freon (R-12) in 1928 was a turning point: this gas was non-toxic, non-flammable and odorless, making domestic refrigerators safe for installation in the kitchen.
In 1927, the company General Electric released the "Monitor-Top" model, which became the first truly mass-produced refrigerator. The compressor in this model was located on top and cooled by natural air circulation. Despite the high price, equal to the cost of a car, the demand for the "Monitor-Top" was enormous, and by the 10th anniversary of the model more than a million units had been sold.

- 🧪 1928 — Synthesis of freon, safe refrigerant.
- 🏠 1927 — Launch of mass production of the "Monitor-Top" model.
- ❄️ 1930s —The appearance of the first models with automatic defrosting.
At the same time, absorption technology developed. In 1922, Swedish engineers Balthasar von Platen and Karl Munters created a silent refrigerator that ran on gas or electricity with no moving parts. The rights to this technology were later bought by the company Electrolux, which still produces refrigerators based on the absorption principle, especially popular in hotels and campsites.
Evolution of refrigerants and environmental safety
For a long time, freon was considered an ideal substance for refrigerators, but in the second half of the 20th century centuries, scientists have discovered its destructive effects on the Earth's ozone layer. In 1987, the Montreal Protocol was signed, which obliged manufacturers to phase out the use of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). This required a new technical revolution in the industry.
Modern refrigerators run on ozone-friendly refrigerants such as R-134a, R-600a (isobutane) and R-290 (propane). Interestingly, the industry has come full circle: isobutane and propane, used in the earliest experiments of the 19th century, have returned in the form of high-tech, environmentally friendly solutions. They have excellent refrigeration properties and zero ozone depletion potential.
⚠️ Attention: Modern refrigerants (R-600a, R-290) are flammable gases. It is strictly forbidden to open the refrigeration circuit yourself or try to refill the refrigerator at home without special equipment and skills.
Why can’t you use old refrigerants?
Freons R-12 and R-22, used in old refrigerators, when released into the atmosphere, rise to the upper layers, where they are destroyed under the influence of ultraviolet radiation, releasing chlorine. One chlorine atom can destroy up to 100,000 ozone molecules.
Replacing refrigerants required changes in the design of compressors and seal materials. Modern oils used in compressors must be compatible with new gases, and the system itself must be completely sealed to prevent the leakage of flammable substances. This has made modern refrigerators more difficult to repair, but much more environmentally friendly.

Each the stage in this table marked not just a technical improvement, but a change in the way people lived. The advent of the freezer made it possible to make supplies for months, and the system No Frost relieved housewives from having to manually defrost the unit every few weeks.
Today we are witnessing a new stage of evolution: the introduction of “smart” technologies, inverter compressors and freshness zones. Modern refrigerators can be controlled from a smartphone, order products via the Internet and independently diagnose faults. The journey from an ice block in the basement to a high-tech center in the kitchen was a long one, but the result was worth it.
Frequently asked questions (FAQ)
Who exactly is considered the inventor the first refrigerator?
It is difficult to name one inventor. Jacob Perkins created the first working prototype in 1834, Carl von Linde developed the first efficient industrial machine in 1876, and Fred Wolf and General Electric were responsible for the first mass-produced household electric refrigerator from 1913 to 1927. Why were old refrigerators so dangerous?
Why were old refrigerators so dangerous?
Until the 1930s, Ammonia, sulfur dioxide and methyl chloride were used as refrigerants. These substances are toxic, explosive or flammable. A leak of such gas in the kitchen could lead to serious poisoning or a fire, so early models required installation in separate rooms.
When did refrigerators become available to ordinary people?
Mass availability began in the USA in the 1930s, after the invention of safe freon and the establishment of conveyor production. In Europe and the USSR, this process stretched over the post-war decades (1950-1960s), when active construction of factories for the production of household appliances began.
How did the first refrigerator work without electricity?
The first absorption refrigerators (for example, the Carré or later Electrolux systems) worked on heating. A gas burner or electric heating element boiled a solution of ammonia in water, separating the components and creating pressure for a cooling cycle. They had no moving mechanical parts, such as a compressor.
Is it still possible to buy an ammonia refrigerator?
