Who and when invented the refrigerator: a brief history

The question of who and when invented the refrigerator often causes controversy, since the path from the idea of keeping cold to a modern household appliance took almost two centuries. It is impossible to name one specific date or one person, since the evolution of refrigeration equipment occurred in stages, going through many experiments and failures. The first attempts at artificial refrigeration were aimed at creating ice, rather than maintaining a constant temperature in a closed cabinet, as we understand today.

The story begins long before the advent of electricity, when humanity used natural ice and snow to preserve food. First prototypesresembling modern units, appeared only in the 19th century thanks to the development of chemistry and thermodynamics. Engineers were looking for ways to compress and expand gases in order to remove heat from products, and this principle underlies the operation of most modern models.

In this article we will examine in detail the key milestones in the development of refrigeration technology, name the main inventors and explain how technologies have changed. Understanding the history of the creation of these devices helps to better understand the principles of their operation and the reasons why modern refrigerators look and function the way they do.

The Age of Ice: Predecessors of Modern Refrigerators

Before the advent of mechanical refrigeration, people for centuries used glaciers - underground storage facilities where snow and ice were transported in winter. In the 18th century, the first prototype of a refrigerator appeared in England, which was called ice box or ice cabinet. It was a wooden box, lined inside with tin or zinc, where pieces of natural ice were placed, and at the bottom there was a tray for draining water.

The operating principle of such devices was simple, but effective for its time. Cold air, being heavier than warm air, fell down, cooling the products placed on the shelves. However the ice quickly melted, it had to be constantly bought and carried in buckets, which was expensive and inconvenient. It was the need to replace natural ice with artificial ice that became the main engine of progress in this area.

It is important to understand that these devices did not produce cold themselves, but only stored it received from the outside. However, the double-walled and thermally insulated design became the foundation for future engineering solutions. Without the experience of creating sealed chambers with insulation, the transition to mechanical systems would have been impossible.

⚠️ Attention: Early models of glaciers required regular cleaning of trays, as stagnant water (standing water) became a source of bacteria and unpleasant odors, spoiling food faster than the cold preserved it.

By the middle of the 19th century The demand for ice grew catastrophically, especially in hot countries and in the navy. The extraction and transportation of natural ice did not keep up with the needs of cities, which created ideal conditions for the introduction of inventions capable of generating cold artificially on an industrial scale.

First steps: chemical experiments and absorption

The answer to the question of who invented the refrigerator is often associated with the name of the American doctor John Gorey. In 1842, he built the first ice-making machine using ether as a refrigerant. Gorey noticed that when ether evaporated, the temperature dropped sharply, and decided to use this effect to cool water. Although his device was bulky and dangerous due to the flammability of ether vapor, it became the first working prototype.

In parallel with Gorey, the Scottish scientist James Harrison worked on similar problems. In 1585, he created the first commercially successful ice-making machine, powered by steam compression. Harrison also introduced the use of refrigerators in breweries and meatpacking plants, which revolutionized the food industry. Its systems operated on ether, but were much more reliable and powerful.

Another important area was absorption. French physicist Ferdinand Carré in 1858 created a machine that ran on a mixture of water and ammonia. Unlike compressor models, there were no moving mechanical parts, and the circulation of the refrigerant was ensured by heating. This invention made it possible to create compact devices, which later became popular in everyday life as gas refrigerators gas refrigerators.

Despite the successes, early machines had serious drawbacks. They were huge, noisy, consumed a lot of energy, and often used toxic or explosive substances. Ammonia, sulfur dioxide and methyl chloride were effective, but the leakage of such gases could lead to poisoning or fire, so installing them in residential buildings was long considered madness.

The birth of the household electric refrigerator

The real revolution occurred at the beginning of the 20th century, when engineers were able to make refrigeration machines compact and safe for the kitchen. In 1911, the company introduced the DOMestic ELectric REfrigerator, designed by engineer Fred Wolf. This device can be considered the first full-fledged household electric refrigerator, although it cost fabulous money for that time. General Electric presented the model DOMELRE (DOMestic ELectric REfrigerator), developed by engineer Fred Wolf. This device can be considered the first full-fledged household electric refrigerator, although it cost fabulous money for that time.

However, mass production became possible thanks to the Dane Christian Steenstrup. In 1915, he improved the design, making it airtight and safe. His patent was bought by a company Frigidaire (a division of General Motors), which began producing models available to a wider range of consumers. It was then that the refrigerator ceased to be a laboratory curiosity and began to penetrate into homes.

The key moment was the invention of a safe refrigerant - freon. Until the 1930s, toxic gases were used, and each accident could cost a life. The company's chemists General Motors i DuPont synthesized dichlorodifluoromethane (R-12), which was inert, non-flammable and safe for humans. This discovery removed the main psychological and technical barrier to the mass introduction of technology.

In the 1920-30s, the design of refrigerators also underwent changes. Enameled cases, convenient shelves and, most importantly, automatic thermostats appeared. The user no longer needed to monitor the temperature or charge the unit with refrigerant - the equipment learned to work autonomously.

Soviet experience: from “Moscow” to “Biryusa”

In the Soviet Union, the history of the creation of refrigerators began later than in the West, but developed at a rapid pace. The first samples were assembled literally by hand in the 1930s at the Compressor plant. However, the real breakthrough came in 1951, when the first serial refrigerator "Moscow" came off the assembly line of the Moscow plant "Compressor" (KHT-120).

The "Moscow" model was a copy of the American General Electric, but adapted to Soviet realities. It had a capacious body, but lacked automatic defrosting and a thermostat in the modern sense - the temperature had to be adjusted “by eye” or by the operating time of the compressor. Despite the noise and size, it was a symbol of comfort and prosperity for the Soviet family.

B Over the next decades, the line expanded: “Saratov”, “Zil”, “Biryusa”, “Oka” appeared. Each plant sought to improve reliability and reduce energy consumption. By the 1970-80s, a refrigerator had become a must-have attribute of every apartment, and Soviet equipment was famous for its maintainability and durability.

⚠️ Warning: Soviet refrigerators often used flammable refrigerants (propane-butane mixtures) or toxic ammonia in more industrial models. When attempting to restore or recycle old Moskva or early Saratov models, care must be taken with the piping system.

Technological evolution: from freon to No Frost

Further development of refrigerators followed the path of increasing convenience and energy efficiency. The main problem remained the need for regular defrosting. Moisture from the food and air condensed on the back wall, turning into an ice coat that had to be chopped off with a knife. In the 1960s, the company General Electric introduced the system No Frost (without frost).

The operating principle of No Frost was forced air circulation. The fan forced air through the evaporator, where it was cooled and dried, and then distributed throughout the chamber. Ice formed only on the hidden evaporator, from where it was removed automatically during periods of compressor inactivity. This saved users from grueling defrosting and made the temperature in the chamber more uniform.

Electronics also developed in parallel. Mechanical thermostats have given way to electronic sensors, displays, freshness zones and the ability to finely adjust the temperature for different departments have appeared. Modern models can be controlled from a smartphone, signaling an open door or expiration date of products.

Today we are seeing a new round of evolution related to the environment. Old freons, which destroy the ozone layer, are prohibited. They have been replaced by natural gases, such as isobutane (R-600a)which is used in most modern refrigerators. It is effective and safe for the atmosphere, although it requires increased tightness of the system due to its flammability.

Modern trends and future of refrigeration equipment

A modern refrigerator is a complex computer with a cooling function. Engineers are introducing inverter compressors that do not turn off completely, but smoothly regulate power, which reduces noise and energy consumption. Double-circuit and triple-circuit systems have appeared that allow you to independently regulate the climate in the freezer and refrigerator compartments.

Particular attention is paid to maintaining freshness. Technologies like Zone Fresh or VitaFresh create conditions under which vegetables remain crisp for weeks, and meat does not lose color. This is achieved by controlling humidity and temperature in individual compartments, which was unthinkable for the first inventors of refrigerators.

The future lies in “smart” functions: cameras inside the case allow you to see products through the smartphone screen, and AI analyzes consumption and can order products itself. However, despite all the electronics, the physical principle of operation - the extraction of heat through the evaporation of the refrigerant - remains the same as in the time of John Gorey.

⚠️ Attention: When purchasing a modern electronically controlled refrigerator in regions with unstable voltage, be sure to use a surge protector or stabilizer. Power surges can damage an expensive control unit, the repair of which is often unprofitable.

The history of the refrigerator is a journey from luxury for the rich to a vital necessity. What began as an attempt to freeze water with ether has grown into a global industry ensuring human food security. And although we rarely think about who and when invented this wonderful cabinet, it is difficult to imagine our life without it.
