The question of who invented the refrigerator does not have one simple answer, since the path from The idea of refrigeration to the modern household appliance took more than two centuries and passed through the hands of dozens of brilliant engineers. Many people mistakenly believe that this invention belongs to one person, but in fact it is the result of the evolution of scientific discoveries in the fields of thermodynamics and chemistry. Initially, humanity used natural ice, delivered from mountainous regions or harvested in winter, which was expensive and unreliable.
The first experiments with artificial cold began in the 18th century, when scientists discovered that the evaporation of certain liquids causes a sharp drop in temperature. It is this principle of evaporative cooling that formed the basis of all future systems. If you are interested in which country gave the world this miracle unit, then it is worth noting the contribution of Great Britain, the USA, Germany and Russia, where active developments were carried out in parallel.
Today it is difficult to imagine life without this device, which has radically changed the diet and culture of food consumption. However, the path to creating a safe and effective compressor was full of experiments with dangerous gases and complex mechanical systems. Let's look at exactly how this technology developed and who was at the origins of the great refrigeration revolution.
Background: from glaciers to the first experiments
Before the advent of mechanical systems, people relied on “ice houses” and cellars, where food was preserved due to low temperature and insulation. In 1755, Scottish chemist William Cullen demonstrated the first known artificial method of refrigeration, using a pump to create a vacuum over a container of ether. This caused the liquid to boil at a low temperature and form a small amount of ice, which was a breakthrough in understanding the physics of the processes.
At the beginning of the 19th century, the American Oliver Evans described a closed cooling cycle using a volatile liquid, but never built a working machine. His ideas seemed fantastic in 1805, but they laid the theoretical foundation for future inventors. It is important to understand that early devices were bulky, inefficient, and often used toxic substances such as sulfuric acid or ammonia, making them impossible to use in the home.
⚠️ Warning: Early refrigerants, such as diethyl ether or methyl ether, were extremely flammable. Experimenting with them at home without special equipment is strictly prohibited due to the high risk of explosion.
By the middle of the 19th century, interest in refrigeration shifted to the industrial sphere, where it was necessary to preserve meat and beer for transportation. Australia and Argentina became the first countries to introduce vapor compression machines on ships for the transport of goods. This made it possible to establish global trade in products, which was previously limited by seasonality and geography.
Jacob Perkins and the first patent for a refrigeration machine
The official "father" of the refrigerator is often called the American inventor Jacob Perkins, who in 1834 received the first patent for a vapor-compression refrigeration machine. His device operated on a cycle that is used in modern refrigerators: compression, condensation, expansion and evaporation of the refrigerant. Perkins used ether as a working fluid, which made it possible to reach freezing temperatures of water.
Despite the successful patent, Perkins' machine did not have commercial success due to the complexity of the design and the danger of the substances used. However, his contribution to development thermodynamics cannot be overestimated. He proved that heat can be transferred against the natural temperature gradient, expending mechanical energy.
Why was ether stopped being used?
Ether had excellent refrigerating properties, but its extreme flammability made the operation of Perkins machines dangerous. Any spark could lead to disaster, so engineers began looking for safer alternatives such as ammonia and sulfur dioxide.
In the ensuing decades, various engineers made improvements to the design. French engineer Ferdinand Carré created an absorption refrigerator in 1859, which did not require a mechanical compressor, but worked by heating. This invention became popular in places where there was no electricity, and was used even at the beginning of the 20th century.
Karl von Linde and the industrial revolution of cold
The real breakthrough in the mass production of cold occurred thanks to the German engineer Carl von Linde. In 1876, he introduced the first efficient vapor compression machine using ammonia, methylamine or sulfur dioxide as a refrigerant. Von Linde's machine was so perfect that it made it possible to create ice on an industrial scale all year round, regardless of the season.
Linde's invention instantly spread throughout the world. Breweries, slaughterhouses and dairies were the first customers to appreciate the benefits of constant cold. It was Germany that at that time became the center of refrigeration engineering, setting the standards for reliability and efficiency.
- ❄️ Linde's ammonia units made it possible to reach temperatures down to -30°C, which was unattainable for ice.
- ⚙️ The introduction of horizontal compressors significantly increased the reliability of the system.
- 🌍 Technology made it possible to build refrigerated warehouses in hot countries where ice was a luxury.
By the end of the 19th century, refrigeration machines began to be installed on ships, which made it possible to import meat from New Zealand and Argentina to Europe. This event changed the world economy and the (eating habits of) millions of people. However, household appliances were still a dream due to their size and the need for constant maintenance.
The advent of household electric refrigerators
The transition from industrial ice to the home refrigerator occurred in beginning of the 20th century. In 1911, the company General Electric introduced the first household refrigerator with an electric compressor, designed by French monk and inventor Marcel Audifrene. However, this device was expensive, noisy and required complex maintenance. In 1913, the company began mass production of models for the home. These early units often had the compressor located in the basement and the cooling coil located in the kitchen, making the system bulky. It wasn't until the 1920s, with the advent of smaller, hermetically sealed compressors, that refrigerators began to find their way into everyday homes.
In 1913 the company Frigidaire (back then Guardian Refrigerator Company) began mass production of home models. These early units often had the compressor located in the basement and the cooling coil located in the kitchen, making the system bulky. It wasn't until the 1920s, with the advent of smaller, hermetically sealed compressors, that refrigerators began to make their way into everyday homes.
⚠️ Warning: Early electric refrigerators (1910s to 1930s) used sulfur dioxide, methyl chloride, and ammonia. The leakage of these gases was deadly. Only in the 1930s was freon synthesized, which solved the problem of toxicity.
By the 1930s in the United States, about 10% of households already had an electric refrigerator. The key point was the invention of freon (R-12) by the company's engineers General Motors i DuPont. This refrigerant was non-flammable, non-toxic and odorless, making household appliances safe. From that moment on, the era of widespread distribution of “white appliances” began.
Refrigerator in Russia: from glaciers to Biryusa
In Russia, the history of artificial cold has its own characteristics. For a long time, the main method of storing food remained glaciers - specially equipped cellars where ice was taken from rivers in winter. Industrial production of refrigeration began in the second half of the 19th century, but was of a local nature.
The Soviet Union set a course for mass production of household refrigerators only in the post-war years. In 1951, the first mass Soviet refrigerator "Moscow" was released, which copied the company's American designs. These models were reliable, but had a primitive defrosting system and a high noise level. General Electric. These models were reliable, but had a primitive defrosting system and high noise levels.
Later, in the 1960s, the famous ZIL and Biryusa refrigerators appeared, which became a symbol of comfort in a Soviet apartment. Engineers from the city of Krasnoyarsk (Biryusa plant) and Moscow (ZIL plant) were able to establish the production of affordable equipment using the domestic element base.
| Model | Year of manufacture | Country/Plant | Features |
|---|---|---|---|
| GE Monitor-Top | 1927 | USA, General Electric | First mass-produced, compressor on top |
| DH-2 (Moscow) | 1951 | USSR, ZIL | Copy of American models, volume 90 l |
| Biryusa-6 | 1960s | USSR, Krasnoyarsk | Reliable, with freezer |
| Samsung RB30 | 2000s | South Korea | No Frost, inverter compressor |
Today the Russian market is saturated with equipment from both domestic and foreign brands. However, the principles of work laid down by Perkins and Linde remain unchanged. Modern models differ only in the level of automation, energy efficiency and the refrigerants used.
The evolution of refrigerants: from ammonia to eco-standards
Safety and environmental friendliness are the main drivers of the development of refrigeration technology in the last 50 years. Following the discovery of the devastating effects of CFCs on the planet's ozone layer in the 1980s, the world community adopted the Montreal Protocol. This required an urgent replacement of refrigerants with safer analogues.
Modern refrigerators run on freons of the brands R134a, R600a (isobutane) and R404a. Isobutane, despite its flammability in high concentrations, is the most environmentally friendly solution, since it does not destroy the ozone layer and has a minimal greenhouse effect. Manufacturers have learned to make systems airtight, reducing the risk of leakage to zero.
☑️ Signs of a refrigerant leak
Engineers are constantly improving heat exchangers and insulating materials, to reduce energy consumption. Modern A++ class models consume several times less electricity than their predecessors from 20 years ago. This is the result of many years of work on the aerodynamics of air flows and the efficiency of compressors.
