Who and when invented the first refrigerator in the world: history from glaciers to modern models

The refrigerator is one of the most important household appliances, without which it is difficult to imagine modern life. But few people think about how and when the first devices for cooling food appeared. The history of refrigeration technology goes back to antiquity, when people used natural sources of cold, but the real revolution occurred only in the 19th century.

Today we will figure out who was behind this discovery, and how technology evolved from primitive glaciers to compact and energy-efficient models. You will learn about key milestones, little-known facts and how refrigerators changed the way of life of mankind. When the world's first refrigerator was inventedwho was behind this discovery, and how technology has evolved from primitive glaciers to compact and energy-efficient models. You'll learn about key milestones, little-known facts, and how refrigerators changed the way we live.

From glaciers to artificial cold: the first attempts to preserve food

For a long time, people relied on natural sources of cold. In Ancient Egypt, Mesopotamia and Persia, food was stored in pits with icedug in the ground. In China, as early as 1000 BC. they used special cellars, where ice brought from the mountains was preserved for months thanks to thermal insulation made of straw and clay.

In the Middle Ages in Europe there appeared ice cellars -deep cellars, where in winter they loaded ice and snow, wrapped them in straw and sawdust. Such storage facilities made it possible to keep food fresh until mid-summer. However, these were passive systems, depending on the climate and season. Ice cellars were clay jugs with porous walls in which water was placed. Evaporation created a slight cooling effect.

• 🏺 Ancient Egypt (c. 2000 BC) - clay jugs with porous walls in which water was placed. The evaporation created a slight cooling effect.
• ❄️ Persia (c. 400 BC) — yakhachals (underground glaciers), where ice was stored all year round.
• 🏯 Japan (Edo era, 17th century) - special himuro - wooden boxes wrapped in cloth soaked in water. The wind created evaporative cooling.

But a real breakthrough occurred only when scientists began to study physical principles of refrigeration. In 1748, a Scottish chemist first demonstrated artificial refrigeration by evaporating ether in a vacuum. This became a harbinger of future refrigeration technologies. William Cullen first demonstrated artificial refrigeration by evaporating ether in a vacuum. This became a harbinger of future refrigeration technologies.

The first refrigerator in the world: the invention of Jacob Perkins (1834)

The first patent for a refrigeration machine was issued in 1834 to the American inventor Jacob Perkins. His device worked on the basis compression cycleusing liquid ammonia as a refrigerant. Although Perkins's device was bulky and dangerous (ammonia is toxic), it laid the foundation for all modern refrigerators.

Perkins' design included four key elements:

1. Compressor - compressed ammonia gas, increasing its temperature.
2. Condenser - cooled the compressed gas, turning it into liquid.
3. Expansion valve - reduced the pressure of the liquid ammonia, causing it to evaporate.
4. Evaporator - absorbed heat from the environment, creating cold.

However, Perkins's first refrigerator was not a household appliance. It was used in industry, such as making ice. The household refrigerator appeared much later - only at the beginning of the 20th century.

⚠️ Attention: early refrigeration systems using ammonia were extremely dangerous. A refrigerant leak could cause poisoning or an explosion. Modern refrigerants (for example, freon) appeared only in the 1920s.

From industrial installations to household refrigerators: evolution in the 19th–20th centuries

After Perkins' invention, refrigeration technologies developed primarily on an industrial scale. In 1856, an Australian inventor James Harrison created the first commercial refrigeration plant for breweries. His system also ran on ammonia, but was more compact and efficient.

By the end of the 19th century, refrigerators began to appear on ships and in the meat processing industry. However, they remained inaccessible for ordinary homes due to:

• 💰 High cost (the first models cost as much as a car).
• ⚡ Dangers (ammonia and other refrigerants were toxic).
• 🔧 Difficulties in maintenance (professional installation was required).

The situation changed in 1913, when the American inventor Fred W. Wolf introduced the first household refrigerator called Domelre (from the words DOmestic ELectric REfrigerator). It was the size of a cabinet, cost about $900 (~$25,000 today), and still used toxic refrigerants. But this was the first step towards the mass distribution of refrigerators.

Why were the first refrigerators so expensive?

The main reason was manual assembly and expensive materials. The housing was made of wood or metal with thick thermal insulation, the compressors were bulky, and the refrigerants (ammonia, sulfur dioxide) required sealed systems. In addition, electricity in itself was a luxury at the beginning of the 20th century, and not all homes were electrified.

Revolution of the 1920s and 1930s: safe refrigerants and mass production

The main obstacle to the spread of refrigerators remained the danger of refrigerants. Everything changed in 1928, when the company developed a non-toxic and non-flammable refrigerant. This discovery made refrigerators safe for home use. Freon (CFC) In 1927, a Swedish company released the first refrigerator, powered by gas or electricity. And in the 1930s, the American DuPont developed Freon (CFC) - non-toxic and non-flammable refrigerant. This discovery made refrigerators safe for home use.

In 1927, a Swedish company Electrolux released the first refrigerator with absorption cycle, which ran on gas or electricity. And in the 1930s, American General Electric began mass production of models with freon compressors. By 1940, refrigerators had become commonplace in middle-class homes in the United States and Europe.

⚠️ Attention: Freon, although safe for humans, was later found to be harmful to the ozone layer. In 1987, the Montreal Protocol prohibiting its use was adopted. Modern refrigerators operate on ozone-safe refrigerants, such as R-134a or R-600a (isobutane).

Interesting fact: in the USSR, the first serial refrigerator KhTZ-120 was released in 1939 at the Kharkov Tractor Plant. It weighed 80 kg and cost 900 rubles - almost half the engineer’s annual salary.

Uses refrigerant R-12 or R-22 (prohibited in most countries)

How refrigerators changed the world: social and economic impact

The emergence of household refrigerators became one of the key technological revolutions of the 20th century. They radically changed:

• 🍗 Food: it became possible to store perishable foods (meat, milk, vegetables) longer, which reduced dependence on seasonality.
• 🏥 Medicine: refrigerators made it possible to store vaccines, medicines and donated blood, saving millions of lives.
• 🌍 Globalization: the development of refrigerated logistics has made it possible to export food products over long distances.
• 👨‍🍳 Culture consumption: supermarkets with a wide range of refrigerated goods have appeared.

Before the invention of refrigerators, families were forced to buy food daily or can it. For example, in 1900, the average American spent 40% of their household budget on food, and by the 1950s this figure had dropped to 20% - largely due to the possibility of long-term storage.

Interesting sociological fact: the spread of refrigerators contributed to emancipation of women. Freed from daily trips to the market and lengthy cooking, women have more time for work and self-development.

Modern refrigerators: from smart technologies to environmental friendliness

Today refrigerators are high-tech devices with inverter compressors, system No Frost, freshness zone and even connection to Wi-Fi. Manufacturers pay special attention to:

• 🌱 Environmental friendliness: use of natural refrigerants (R-600a, R-290) and energy-efficient compressors.
• 🤖 Smart functions: remote control, cameras inside the chamber, voice assistants.
• 🍎 Specialized areas: compartments with controlled humidity for fruit, wine cabinets, blast freezers.

One of the most innovative refrigerators of recent years - Samsung Family Hub with a touch screen, a built-in assistant Bixby and the ability to view recipes directly on the door. And the model LG InstaView Door-in-Door allows you to look inside without opening the door, thanks to the glass panel.

Future trends:

• 🔋 Refrigerators on solid-state elements (without compressor and refrigerant).
• ♻️ Completely recyclable materials for housings.
• 🧠 Artificial intelligence for automatic control food freshness.

Little-known facts about the first refrigerators

The history of refrigerators is full of curiosities and unexpected discoveries. Here are a few facts that you are unlikely to have heard about:

1. A refrigerator running on kerosene. In the 1920s, the company Servel produced absorption refrigerators that could run on kerosene, gas or electricity. They were bought for homes without electricity.
2. Ice from... horse manure. In the 19th century in the USA there were “ice farms” where manure was mixed with straw and water. When decomposed, the mixture released heat, which was used to make ice in the winter.
3. The beer refrigerator saved the life of the president. In 1881, after an assassination attempt on the US President James Garfield doctors used a prototype refrigerator to cool his room. This helped reduce the temperature and alleviate the condition of the wounded.
4. The first refrigerator in space. In 1965, a mini-refrigerator was installed on board the ship for experiments with food in weightlessness. Gemini-4 a mini-fridge was installed for experiments with food in zero gravity.

Did you know that in the 1930s in the USA there were "ice pirate wars"? Ice companies competed so aggressively that they sometimes stole ice from each other or put salt in other people's glaciers to speed up the melting.

FAQ: Frequently asked questions about the first refrigerator

🔍 Who is considered the “father” of the refrigerator?

Officially the first inventor of the refrigerator is recognized Jacob Perkins, received a patent in 1834. However, its design was industrial. The first household refrigerator was created Fred W. Wolf in 1913 (Domelre).

💡 How do modern refrigerators work compared to the first models?
