Many users, wondering about when 1 refrigerator appeared, do not even suspect that the path to a modern kitchen unit took several centuries. For a long time, the only way to preserve food was to use natural ice, which was mined in winter and stored in special glaciers - deep cellars with thick walls. It was a labor-intensive task, dependent on the vagaries of nature, and did not guarantee the safety of food in the hot summer months.
The turning point in history was the era of the industrial revolution, when engineers began to look for ways to artificially produce cold. History of the refrigerator it began not with a household appliance, but with bulky industrial units used to cool beer and meat in factories. It was these experiments that laid the foundation for the technologies we use today, allowing us to keep food fresh all year round without the use of ice.
In this article we will take a detailed look at the chronology of inventions, determine the exact date of the appearance of the first full-fledged household refrigerator and consider how cooling technologies have changed. You'll learn about key figures, such as Jacob Perkins and Carl von Linde, whose discoveries revolutionized the idea of food storage. We will also discuss the evolution of refrigerants and designs that have led to the emergence of quiet and energy-efficient models.
The Age of Ice: Predecessors of Modern Units
Before the invention of mechanical refrigeration, humanity relied on for “ice cabinets” - wooden boxes insulated with cork, sawdust or straw. A block of natural ice was placed inside such a cabinet, which, when melted, absorbed heat from the chamber. Temperature the inside depended on the frequency of ice replacement, which was expensive and inconvenient. Such devices were popular in the 19th century, but they only slowed down the spoilage and did not stop it completely.
The first attempts to create artificial cold date back to the 18th century. A Scottish professor William Cullen in 1748 demonstrated the possibility of producing ice by evaporating ether in a vacuum. However, its installation was more of a scientific curiosity than a practical device. Almost another hundred years passed before the technology became suitable for commercial use.
By the middle of the 19th century, the need for artificial ice has become critical for the meat processing industry. It was necessary to transport meat across oceans, and natural cold was no longer sufficient. This stimulated engineers to look for more efficient methods of the cooling cyclebased on the compression and expansion of gases.
The first working refrigerator: Perkins' experiments
The official date of the appearance of the first working refrigeration device is considered to be 1834. It was then that the American inventor Jacob Perkins received a patent for a machine operating on the principle of a vapor compression cycle. His apparatus used ether, which evaporated at low pressure, absorbing heat, and condensed back into liquid at high pressure.
Although Perkins' apparatus could produce small amounts of ice, it was not widely used due to its high cost and difficulty of maintenance. Ether was flammable, and the seals of that time quickly failed. Nevertheless, the operating principle laid down by Perkins remains the basis for the operation of most modern refrigerators. compressor, pioneered by Perkins, remains the basis for the operation of most modern refrigerators.
⚠️ Attention: Early experimental models often used toxic or explosive substances (ammonia, sulfur dioxide, ether). Attempts to repeat these experiments at home are strictly prohibited due to the risk of poisoning or explosion.
In the following decades, various engineers made improvements to the design. The Frenchman Edmond Carré in the 1850s created an absorption machine that ran on a mixture of water and sulfuric acid, and later on ammonia. These devices were more reliable and began to be used for the industrial production of ice, which was then sold to the public.
The birth of the household refrigerator: the beginning of the 20th century
The real boom occurred at the beginning of the 20th century, when technology reached the average consumer. Many people mistakenly believe that the first household refrigerator appeared immediately after the invention of electricity, but the journey took time. In 1913, the company General Electric introduced the DOMELRE model (DOMestic ELectric REfrigerator), which became the first electric refrigerator for the home.
DOMELRE was a bulky, noisy and very expensive device. It consisted of two parts: the upper one, where the ice maker was located, and the lower one for storing food. The compressor was located under a cabinet and required constant maintenance. Despite the shortcomings, it was a breakthrough: you no longer had to wait for the iceman.
In 1927, the company General Electric introduced the model Monitor-Top. It was the first mass-produced refrigerator with a hermetically sealed compressor located on top of the body (hence the name, reminiscent of a monitor warship). The device ran on sulfur dioxide, was reliable, and ushered in the era of mass introduction of refrigerators into American homes.
By the 1930s, competition between manufacturers led to lower prices and improved performance. Models with automatic defrosting and safer refrigerants appeared. FreonInvented in 1928, it became an industry standard, replacing toxic gases and making refrigerators safe to install right in the kitchen.
Evolution of refrigerants and technologies cooling
The history of the refrigerator is also the history of the search for the ideal refrigerant. Early models used ammonia, propane, methyl chloride and sulfur dioxide. All of them had serious drawbacks: toxicity, flammability or corrosivity. Engineers needed a substance that was chemically inert, nonflammable and effective.
In 1928, Thomas Midgley Jr. developed Freon-12 (dichlorodifluoromethane). This gas was a revolution: it was safe for humans (odorless and colorless) and stable. However, by the end of the 20th century it became clear that freons destroy the Earth's ozone layer. This has led to new changes in the design and charging of refrigeration systems.
☑️ Signs of a refrigerant leak
Modern refrigerators run on isobutane (R600a) or propane. These substances are environmentally friendly, but flammable. That is why the instructions for new models contain strict warnings about the prohibition of mechanical damage to the evaporator tubes. Safety is now a higher priority than in the era of the first experiments.
| Refrigerant type | Period active use | Features and risks |
|---|---|---|
| Ether, alcohol | 1830–1860 | High fire hazard, low efficiency |
| Ammonia, sulfur dioxide | 1860–1930 | Toxic, corrosive, required frequent repairs |
| Freon (R12) | 1930–1990 | Safe for humans, but harmful to the environment |
| Isobutane (R600a) | 1990–present | Eco-friendly, energy efficient, but flammable |
Soviet refrigerators: from "KhTZ" to "Biryusa"
In the Soviet Union, the history of household refrigeration began later than in the USA and Europe. The first samples appeared in the late 1930s, but mass production started only after the war. The legendary refrigerator KhTZ-120 (Kharkov Tractor Plant) became a symbol of post-war reconstruction. It was simple, reliable and repairable.
In the 1960s, more modern models came to replace them, such as ZIL and Saratov. They already had automatic defrost and quieter compressors. Design has become more important: colored enamels, chrome handles and interior lighting have appeared. The refrigerator has turned from a utilitarian cabinet into the central element of the kitchen.
Why did Soviet refrigerators work for decades?
Simplicity of design, absence of complex electronics, thick metal body and the ability to repair any part they were made by hand to be practically immortal.
By the 1980s, Soviet industry was producing millions of pieces of equipment per year. Models Oka, Biryusa i Don were exported to many countries. However, by the end of the century, they began to be inferior to foreign analogues in energy efficiency and noise level, which led to the need to modernize factories.
⚠️ Attention: Old Soviet refrigerators (manufactured before 1990) often contain glass wool or phenolic resin insulation, as well as refrigerants that are banned today. When disposing of such equipment, compliance with special environmental standards is required.
Modern technologies: No Frost and smart home
The current stage of development of refrigeration equipment is characterized by the implementation of the system No Frost. If previously users had to regularly defrost the chambers manually by chipping the ice with a knife, now ventilation and special heaters make this process automatic. This is not only convenient, but also extends the life of the compressor.
Modern models are equipped with inverter compressors that operate silently and smoothly regulate power. Smart refrigerators they can control the temperature via a smartphone, order products online and even show the contents of the chambers through the built-in cameras. Technology has come a long way since the first ice chest appeared.
Despite the complexity of the electronics, the basic principle remains the same: compression and gas expansion to extract heat. Engineers continue to work to improve efficiency and use environmentally friendly materials. The future probably belongs to refrigerators that can completely recycle their waste or run on alternative energy sources.
Frequently asked questions (FAQ)
In what year was the first electric refrigerator invented?
The first electric refrigerator for home use, which became widely known, was introduced by General Electric in 1913 (model DOMELRE). However, it became widespread and accessible only in the late 1920s with the advent of the Monitor-Top model.
Who is considered the inventor of the principle of operation of the refrigerator?
The founder of the principle of the vapor compression cycle is considered to be an American Jacob Perkinswho received a patent in 1834. It was his machine that first demonstrated the possibility of a continuous refrigeration cycle, which is still used today.
Why can't you open the door on older refrigerators?
Models of the 1950s and earlier used snap locks that could only be opened from the outside. Children, having played too much, could slam the door and get stuck inside, which led to suffocation. Modern refrigerators have magnetic seals or mechanisms that allow even a baby to open the door from the inside.
When did they stop using freon in refrigerators?
The process of eliminating ozone-depleting freons (R12) began after the 1987 Montreal Protocol. By the early 2000s, most manufacturers switched to safer refrigerants, such as isobutane (R600a) and tetrafluoroethane (R134a).
