A refrigerator is one of the most important household appliances in a modern home, without which it is difficult to imagine everyday life. But few people realize that the path from the first attempts to keep food cool to compact and energy-efficient models took more than two centuries. When did refrigerators appear in the form to which we are accustomed? And how did ancient civilizations cope without electricity?
The history of food refrigeration goes back to ancient times, when people used natural sources of cold - glaciers, basements and even the night sky. However, the real revolution occurred only in the 18th–19th centuries, when science and technology made it possible to create the first artificial cooling systems. Today we will talk about the key stages of this evolution: from experiments with ether to the emergence of compressor refrigerators and innovative technologies No Frost.
Ancient cooling methods: how they managed without technology
Long before the invention of electricity, people were looking for ways to keep food fresh. Archaeological finds confirm that already in Mesopotamia and Ancient Egypt, basements and wells were used to store food. And in Persia (modern Iran) special towers were built - 3000 BC in Mesopotamia and Ancient Egypt, cellars and wells were used to store food. And in Persia (modern Iran) they built special towers - yakhchals - which captured cold night air and maintained low temperatures during the day.
Popular in the Middle Ages in Europe and Russia received glaciers - wooden or stone rooms, insulated with straw or peat, where ice was stored in winter. Such structures could retain cold until summer, and sometimes longer. For example, in Moscow back in the 19th century there were ice cellarswhere ice was delivered from frozen rivers and lakes.
- 🏺 Ancient Egypt: clay jugs with porous walls that cooled due to the evaporation of water.
- ❄️ Scandinavia: underground storage facilities where food was frozen naturally in winter.
- 🏯 Japan: use of snow from mountainous regions to cool food in aristocratic houses.
It is interesting that in some regions glaciers existed until the middle of the 20th century. For example, in the USA back in the 1920s about 40% of households used ice delivery for household glaciersuntil they were replaced by electric refrigerators.
The first steps of science: experiments with cooling (XVII-XVIII centuries)
The scientific approach to refrigeration began to develop during the Enlightenment. The English philosopher Francis Bacon first described the method of freezing meat using snow, and the Scottish chemist demonstrated artificial cooling by evaporating ether in a vacuum. This experiment was the first step towards the creation 1620 English philosopher Francis Bacon first described the method of freezing meat using snow, and in 1748 Scottish chemist William Cullen demonstrated artificial refrigeration by evaporating ether in a vacuum. This experiment was the first step towards creating vapor compression systems.
However, the real breakthrough occurred in 1755when an American inventor Benjamin Franklin and a chemist John Hadley conducted an experiment with the evaporation of alcohol and ether, achieving a temperature drop to −14°C. This principle formed the basis of future absorption refrigeratorswhich were later used in everyday life.
| Year | Inventor | Achievement |
|---|---|---|
| 1620 | Francis Bacon | Described the method of freezing with snow |
| 1748 | William Cullen | Evaporated ether for cooling |
| 1755 | Benjamin Franklin, John Hadley | Achieved −14°C by evaporating alcohol |
| 1805 | Oliver Evans | Patent for a steam compressor cycle |
⚠️ Attention: early experiments with ether and ammonia were extremely dangerous. These substances are toxic and explosive, so modern refrigerators use safe refrigerants (for example, R-134a or R-600a).
Invention of the first refrigerator: who and when created the working model
First practical. refrigerator was invented by 1834 an American Jacob Perkins. His device worked on the basis of vapor compression cycle using ether as a refrigerant. However, the device was cumbersome, unreliable and was not widely used.
The decisive step was taken by Karl von Linde a German engineer who in 1876 developed the first industrial refrigerator with an ammonia compressor. His invention made it possible to cool breweries and meat processing plants, and later was adapted for domestic needs. He created 1879 Ferdinand Carré created absorption refrigeratorwhich worked on water and ammonia and was safer. compressor models.
- 🔧 1834: Jacob Perkins patented the first vapor compression refrigerator (ether).
- ⚙️ 1851: John Gorrie received a patent for a machine for making ice (prototype air conditioner).
- 🍺 1876: Carl von Linde launched industrial refrigeration for breweries.
- 🏠 1913: the first household refrigerator Domelre (USA, price ~$1000).
Interestingly, the first household refrigerators were a luxury: in 1920s their cost reached $500–$1000 (about $15,000 in modern money). Only by the 1930s did prices begin to fall due to mass production.
Why were the first refrigerators dangerous?
Many early models used ammonia or sulfur dioxide as a refrigerant. These substances are toxic, and if leaked, could cause poisoning or even an explosion. For example, in the 1920s, deaths were recorded in the United States due to the explosion of refrigerators due to faulty compressors.
The era of mass production: how refrigerators entered. into every home (1920–1950s)
The beginning of the 20th century was a turning point: in 1913 the company Fred W. Wolf released the first serial household refrigerator Domelre, and in 1918 Kelvinator introduced a model with automatic control. However, the real boom occurred in the 1920s and 1930s, when safe refrigerants were developed - freons (group CFC).
Key milestones of this period:
- 📦 1923: Frigidaire (subsidiary company General Motors) released the first refrigerator with a hermetic compressor.
- ❄️ 1925: Electrolux began production of absorption refrigerators (powered by kerosene or gas).
- 💡 1939: General Electric introduced a model with automatic defrosting.
During World War II the production of household refrigerators decreased, but after 1945 demand soared: to 1955 more 80% of American homes had a refrigerator. In the USSR, the first production models (ZIS-Moskvich) appeared only in 1951.

Technical revolution: from No Frost to smart refrigerators (1960s–2000s)
The second half of the 20th century brought radical changes:
- 1960s: emergence No Frost systems (automatic defrosting).
- 1970s: transition to R-12 refrigerants i R-22, safer than ammonia. data-i="187">1970s
- 1990s: introduction inverter compressors (energy savings up to 30%).
- 2000s: the first models with displays, Wi-Fi and touch control.
It is especially worth noting 1992when the company Whirlpool released the first refrigerator with a system Adaptive Defrostthat regulated defrosting cycles depending on humidity. And in 2000 LG presented a model with linear compressorwhich worked quieter and longer than usual.
⚠️ Attention: refrigerants R-12 and R-22 (used until the 2000s) are banned today due to harm to the ozone layer. Modern refrigerators run on R-134a, R-600a (isobutane) or R-290 (propane).
Modern technologies: what refrigerators of the 21st century can do
Today refrigerators are not just “cooling boxes”, but high-tech devices with artificial intelligence. Here are the key innovations of recent years:
- 📱 Smart control: control via a smartphone (for example, Samsung Family Hub with a 21.5" screen).
- 🌡️ Multi-zone cameras: different temperature conditions in one compartment (for example, LG InstaView).
- 🔋 Energy efficiency: classes A+++ i A++++ (consumption from 100 kW/year).
- 🦠 Antibacterial coatings: silver ions or BioFresh from Liebherr.
One of the most impressive achievements is magnetic cooling (technology Magnetic Refrigeration), which does not require refrigerants. Cooltech Applications is already testing such systems for industry, and by 2030 they may appear in household models.
| Technology | Advantages | Model example |
|---|---|---|
| No Frost | No ice, uniform cooling | Bosch KAN92VI30R |
| Inverter Compressor | Quiet operation, energy saving | LG GA-B489TGQL |
| Twin Cooling | Separate air flows for the refrigerator and freezer compartments | Samsung RB37A52N0SA |
| Vacuum Zone | Vacuum packaging of food directly in the refrigerator | Panasonic NR-BN30A1 |
The future of refrigerators: what technologies await us
Manufacturers are already working on a new generation of refrigerators:
- 🤖 Assistant robots: for example, Samsung Bot Chef, which itself will take out food by voice command.
- 🌿 Biodegradable materials: bodies made of recycled plastic or mushroom mycelium.
- ☁️ Cloud services: the refrigerator will order products through Amazon Fresh or SberMarket in their absence.
- 🔋 Autonomous power supply: models with solar panels for regions with power outages.
Experts predict that by 2035 refrigerators will become part of smart home and will interact with other devices. For example, they will be able to:
- Sync with multi-cookerto defrost food at the right time.
- Analyze expiration dates and send notifications about expiration.
- Optimize temperature depending on the weather (via data from meteorological services).
⚠️ Attention: smart refrigerator technologies require an Internet connection, which creates risks of cyber attacks. In 2021, hackers hacked more than 10,000 devices IoT (including refrigerators) for cryptocurrency mining. It is recommended to regularly update the firmware and use complex Wi-Fi passwords. data-i="269">Attention:
FAQ: answers to frequently asked questions about the history of refrigerators
🔍 When did the first electric refrigerator for the home appear?
The first serial household electric refrigerator — Domelre was released in 1913 company Fred W. Wolf (USA). However, mass distribution began only in the 1920s after the invention of the hermetic compressor.
