The question of who exactly created the first refrigerator does not have one simple answer, since the path to a modern household appliance took more than a century and a half. The history of food refrigeration is a series of brilliant insights, unsuccessful experiments and gradual improvement of technologies that ultimately led to the emergence of compression cycle. Many believe that the invention occurred in the 20th century, but the first prototypes appeared much earlier, when humanity was just beginning to comprehend the laws of thermodynamics.
Initially, people used natural ice, but the need for artificial refrigeration arose long before the advent of electricity. The key figures were scientists and engineers from different countries, each of whom contributed to the development of compression systems. It was their joint efforts that made it possible to create a device that today stands in every kitchen and preserves food freshness. absorption and compression systems. It was their joint efforts that made it possible to create a device that today is in every kitchen and preserves food freshness.
In this article we will analyze the chronology of events, determine which year can be considered the date of birth of the refrigerator, and find out how this technique has evolved. You will understand why the first models were dangerous, and which inventions became truly revolutionary. The history of the creation of the refrigerator is a fascinating example of engineering.
Backgrounds for the creation of artificial cold
Before the advent of mechanical devices, the only way to preserve food was to collect ice in winter and store it in special glaciers. However, this method was seasonal and climate dependent, requiring a more reliable solution. Scientists began experimenting with the evaporation of volatile liquids, noticing that this process was accompanied by the absorption of heat. It was this physical principle that formed the basis for the operation of all future refrigeration machines. In the 18th century, Scottish professor William Cullen demonstrated the first artificial cold, using a pump to create a vacuum over diethyl ether. Although his installation was not intended for domestic use, it proved the possibility of producing cold artificially. This discovery became the foundation for further research in the fields of thermodynamics and cryogenics. refrigeration machines.

⚠️ Warning: Early experiments were often carried out using toxic or explosive substances such as ether and ammonia, which made them extremely dangerous for home use.
Later, the American doctor Oliver Evans described a theoretical model of a refrigeration machine operating in a closed loop. cycle, although he never physically built it. His ideas were implemented by another inventor who was able to create a working prototype. Thus, the theoretical basis was ready for practical implementation.
The first practical models of the 19th century
The first person to build a working refrigerator is the American Jacob Perkins. In 1834, he received a patent for a device using the evaporation of ether in a vacuum to cool water. His machine could produce ice, but was too bulky and expensive for mass use, remaining more of a laboratory curiosity. However, 1834 is often cited as the date of the first refrigerator.
In the mid-19th century, Australian James Harrison created a more advanced system based on ether compression, which was successfully used for brewing and meat processing plants. His plants were the first to produce ice on an industrial scale, which revolutionized the food industry of the time. However, household refrigerators were still a dream due to the difficulty of maintenance.
In the 1850s, French engineer Edmond Carré developed an absorption refrigerator that ran on a mixture of water and ammonia. This technology did not require a mechanical compressor, making it more reliable, although less efficient. Absorption models subsequently became popular in areas where there was no reliable power supply.
- 🧊 Jacob Perkins —created the first working closed-cycle machine in 1834.
- 🍺 James Harrison —introduced the commercial use of refrigerators into Australian industry.
- ⚗️ Edmond Carré —developed a safe absorption system without moving parts.
Electrification and the emergence of household models
The real breakthrough occurred at the beginning of the 20th century, when electricity became available to the broad masses. In 1913, the company General Electric introduced the first household refrigerator with an electric compressor, designed by engineer Fred Wolf. This unit, known as Audiffren-Singreen, still used sulfuric acid and sulfur dioxide, which was unsafe, but it marked the beginning of the era of home refrigeration.
Mass production began a little later, thanks to the efforts of the company Frigidaire (a division of General Motors). In the 1920s, they began producing reliable models that could be installed in the kitchen of an ordinary family. The cost gradually decreased, making the “miracle cabinet” accessible to the middle class.
Why were the first refrigerators so noisy?
Early compressors operated in an open cycle and did not have high-quality insulation. In addition, the refrigerants used required high pressure to condense, which created a strong vibration noise and hum comparable to the operation of a modern motorcycle.
An important milestone was the invention of freon in 1928 by Thomas Midgley. This gas was non-flammable and non-toxic (unlike ammonia and sulfur dioxide), allowing refrigeration units to be placed directly inside a kitchen cabinet rather than in the basement or yard. This invention made the refrigerator a truly home appliance.
⚠️ Attention: Although safe for humans, CFCs were later found to be destructive to the ozone layer, which led to their ban in the 1980s and the transition to new refrigerants.
Key inventors and their contributions
The history of the refrigerator is the result of the work of many engineers, whose names often remain in the shadows. It is important to highlight those whose developments have become the basis for modern technology. For example, the Dane Christian Stenhausent in the 1870s created the first machine powered by carbon dioxide, which was a safer alternative to ammonia.
American Carl von Linde at the end of the 19th century developed a process for liquefying air and created the first efficient compression machine that was used in industry. One of the world's largest companies for the production of refrigeration equipment bears his name - Liebherr (although the brand is named after the founder of the company, Linde's technologies lie at the heart of the industry).
We should also not forget about the Soviet engineers who in the 1930s launched the production of refrigerators "KhTZ" and the famous "ZIS-KH", ensuring the safety of products in the conditions of a huge country. Each of these models required adaptation of technologies to local operating conditions.

Evolution of refrigerants: from ether to eco-gases
The safety and efficiency of a refrigerator directly depend on the refrigerant used. At the beginning of the journey, flammable substances such as ether and butane were used, which often led to fires. The industry then switched to ammonia and sulfur dioxide, which were effective but toxic if leaked.
The discovery of freon (R-12) became the gold standard for half a century, allowing the creation of safe and compact models. However, at the end of the 20th century, it was discovered that chlorofluorocarbons were destroying the Earth's ozone layer. This led to the Montreal Protocol and the search for new substances.
Today, modern refrigerators use hydrofluorocarbons (HFCs), such as R600a (isobutane), which again brings us back to hydrocarbons, but in safe microdoses. These gases do not destroy the ozone layer and have excellent thermodynamic properties.
- 🌿 Natural refrigerants —a return to the use of propane and isobutane in modern safe systems.
- 🚫 Freons (CFC) — prohibited due to environmental damage, but historically important for the development of the industry.
- ⚡ Ammonia - still used in industrial absorption refrigerators and camping models.
Modern technologies and the future refrigerators
Today, a refrigerator is a complex electronic device with microprocessor control. Systems No Frost relieved users of the need for manual defrosting, and inverter compressors made the equipment quiet and energy efficient. Smart refrigerators can order food, monitor expiration dates and be controlled from a smartphone.
Engineers continue to work to improve energy efficiency, introducing vacuum insulation panels and more advanced compressors. The future lies in technologies that minimize energy consumption and completely eliminate harmful emissions.
☑️ What to look for when choosing a refrigerator
When choosing equipment, it is worth remembering that the basic principles laid down by Perkins and Linde still work, just at a higher technological level level. Understanding the history helps to better evaluate the capabilities of modern devices.
⚠️ Attention: When purchasing, pay attention to the type of refrigerant indicated on the nameplate. R600a models require special care during transportation and repair due to the flammability of the gas.
