The history of food preservation is the history of human survival. For a long time, the only way to extend the life of perishable food was to collect ice in winter and store it in deep cellars. However industrial revolution set the engineers the task of creating a machine capable of producing cold artificially, regardless of the time of year and weather conditions. It was this technological leap that made it possible to change the gastronomic habits of millions of people.
Many mistakenly believe that the electric refrigerator appeared suddenly, like a miracle of technology. In fact, the path to mass production took almost the entire 19th and early 20th centuries. The first attempts to create artificial refrigeration were cumbersome, dangerous and accessible only to the richest strata of society. It is important to understand that the invention of the refrigerator was not one event, but a chain of discoveries, each of which brought us closer to a familiar household appliance in the kitchen.
In this article we will analyze in detail the chronology of events in order to accurately answer the question of when the first refrigerator was invented. We will go from the theoretical calculations of physicists to the appearance of the first production model that an ordinary person could buy. You will learn about the risks of early refrigerants and how the design of storage chambers changed.
Background: from glaciers to absorption
Before the advent of mechanical devices, people used glaciers special storage facilities where ice collected in winter was stored for months. However, in 1805, American inventor Oliver Evans described a theoretical model of a machine that used a closed cycle of evaporation of a volatile liquid to create cold. He never built a working prototype, but his ideas formed the basis for future inventions.
The first who was able to bring the theory to life was the American doctor John Gorey. In 1844, he demonstrated an apparatus capable of producing ice and cooling air. Gori system worked on compressing ether, which was extremely dangerous due to the flammability of the substance. Nevertheless, this was the first step towards the creation of an artificial climate.
In parallel, the direction of absorption refrigerators developed. French engineer Ferdinand Carré in 1858 created a machine that runs on a mixture of water and ammonia. Its device did not require complex compressors and could operate on direct heating. Absorption cycle became key for household models of the early 20th century, as it was easier to manufacture.
⚠️ Attention: Early models of refrigerators used ammonia, sulfur dioxide and methyl chloride as refrigerants. These substances are toxic and explosive. The operation of such devices in residential premises without ventilation was deadly.
The development of technology was uneven. While some engineers were improving compressors, others were looking for safe ways to insulate the chambers. The first units were the size of a room and were installed in ice manufacturing plants or breweries. Household use seemed then to be a distant future.
The first electric refrigerator: the birth of an idea
The real breakthrough occurred at the beginning of the 20th century, when electricity began to penetrate into the homes of citizens. In 1910, the company General Electric introduced the first electrically powered household refrigerator. However, this model was still far from perfect: the compressor was located in the basement, and the cold was supplied through pipes to the kitchen.
The situation changed dramatically in 1913, when engineer Fred W. Wolf from Chicago created a device called DOMELRE (Domestic Electric Refrigerator). It was the first self-contained unit that could be installed directly in the kitchen. It consisted of a food box and a compressor mounted on top.
Despite its bulkiness and high noise level, DOMELRE became the forerunner of all modern refrigerators. The cost of such a miracle of technology was about $900, which at that time was comparable to the price of a good car. Therefore, at first the demand was minimal, and the device was considered a luxury product.
Engineers continued to work on reducing size and increasing efficiency. The key point was the introduction of automatic thermostats, which made it possible to maintain constant temperature without constant human intervention. This made the device truly convenient for everyday use.
The evolution of refrigerants: from ammonia to freon
Safety was the main brake on the mass adoption of refrigerators. The use of flammable and toxic substances required ideal tightness, which the technologies of the beginning of the century could not provide. Leaks led to fires and poisoning, which frightened potential buyers.
In the 1920s, the company Frigidaire (a division of General Motors) began an active search for a safe substitute. A group of chemists led by Thomas Midgley managed to synthesize dichlorodifluoromethane, which later became known as Freon-12. This substance was inert, non-flammable under normal conditions.
The appearance of freon was a revolution. It allowed:
- 🧊 Completely seal the system, making it safe for residential premises.
- ⚙️ Simplify the design of compressors and increase their service life.
- 🏠 Start mass production of compact models for middle-class kitchens.
With the introduction of freon, the production of refrigerators has grown exponentially. If in the 10s of the 20th century there were thousands of them, then by the 30s the number was already in the millions. Refrigerants new generation became the industry standard for many decades, until at the end of the century the question of their impact on the ozone layer was raised.
Mass production and lower prices
The 1930s became a period when the refrigerator ceased to be a luxury item. Competition between manufacturers such as Kelvinator, Frigidaire and GEhas led to lower prices and improved designs. Models with automatic defrosting and adjustable shelves appeared.
An important step was the introduction of a steel body instead of wood. Wooden cabinets, popular in the 1920s, did not hold heat well and were a fire hazard. The transition to metal made it possible to use more efficient thermal insulation fiberglass, and then polyurethane foam.
Sales statistics show explosive growth:
| Year | Production in the USA (thousand units) | Average price (dollars) | Share of households with a refrigerator |
|---|---|---|---|
| 1920 | 5 | 750 | < 1% |
| 1930 | 800 | 270 | 8% |
| 1937 | 1800 | 150 | 25% |
| 1950 | 5000+ | 200 | 90% |
By the end of the 30s in the United States, every fourth home already had an electric refrigerator. The Second World War briefly stopped the production of civilian equipment, but after 1945 a real boom began. The refrigerator has become a symbol of post-war prosperity and a standard of modern life.
⚠️ Attention: When purchasing an antique refrigerator (manufactured before 1950), remember that its insulation may contain asbestos and the door seals may contain lead. Restoration of such models requires compliance with safety measures.
Soviet experience: when the refrigerator appeared in the USSR
In the Soviet Union, the history of the refrigerator developed as usual. The first samples were imported or collected under license. Mass production began later than in the West. A significant event was the appearance of the model KhTZ-120 in 1937 at the Kharkov plant.
This unit worked on the absorption principle (using kerosene or gas), since the electrification of rural areas had not yet been completed. However, the refrigerator ZIS-Shbecame widespread and electric, the production of which was launched by the ZIL plant in 137. This date is often called the time when the first affordable refrigerator appeared among Soviet citizens.
The shortage of quality equipment persisted for many years. A popular model Saratov or Biryusa became a source of pride for the family and was bought “by coupons” or on a first-come, first-served basis. The design was simple: a small freezer, manual defrosting and a reliable, albeit noisy compressor.
Why did Soviet refrigerators work for decades?
Simplicity of design. They did not have complex electronics, and the wall thickness and the amount of copper in the compressor were excessive by modern standards, which provided a huge margin of safety.
Only by the 1970-80s did refrigerators in the USSR become truly widespread. Two-chamber models, systems No Frost (albeit belatedly) and a more ergonomic design appeared. Today the market is completely saturated with appliances of any class, from budget models to premium multi-door systems.
Modern technologies and the future of cooling
Today it is difficult to imagine that once a refrigerator simply froze. Modern devices are complex computerized systems. They know how to plot energy consumption graphs, order products online and diagnose faults remotely.
Main directions of development:
- 🌱 Environmental friendliness: Complete rejection of freons in favor of natural refrigerants.
- 💡 Energy efficiency: Consumption classes A+++ allow you to spend a minimum of electricity.
- 📱 Smart functions: Internal cameras, touch screens and control from a smartphone.
Inverter compressors replaced old models with constant on and off. This made the operation of the devices silent and durable. Linear Cooling Technology and similar systems maintain temperature with an accuracy of 0.1 degrees, which is critical for storing delicacies and medicines.
☑️ What to look for when choosing a modern refrigerator
The future probably lies with magnetic cooling and other physical principles that will make it possible to abandon compressors altogether. But even the most advanced developments are based on the fundamental principles of thermodynamics that were discovered more than a century ago.
Frequently asked questions (FAQ)
Who exactly invented the first refrigerator?
It is impossible to name one person. John Gorey created the first working machine in 1844, but Oliver Evans described the principle earlier. Fred Wolf made the first household appliance in 1913, and Carl von Linde developed the efficient compressor. This is a collective achievement of science.
Why were the first refrigerators so expensive?
The high cost is due to the complexity of manufacturing hermetic compressors, the lack of mass production and the high cost of materials. In addition, electricity in homes was rare, which narrowed the market to the super-rich.
When did refrigerators become safe for the home?
The introduction of freon in the early 1930s was a turning point. Previously, using ammonia and sulfur units in bedrooms or living rooms was considered risky due to the possibility of gas leakage.
Do old absorption refrigerators still work?
Yes, the absorption principle (heating the mixture instead of compressing the gas) is still used in silent hotel refrigerators and in car models, operating on gas or 12/24V. They are reliable, but less energy efficient.
What is the service life of the first electric refrigerator?
Early models (1910-1920s) often broke down due to problems with sealing and electric motors. Their service life rarely exceeded 3-5 years. Modern appliances last 10-15 years or more thanks to improved materials.
