Many users, faced with breakdowns of household appliances or When choosing a new model, they think about how complex the path of engineering thought is that led to the creation of a modern one. It is difficult to imagine a kitchen without a device that preserves food freshness, but two centuries ago humanity made do with glaciers and cellars. The answer to the question of when the first refrigerator was created goes back to the depths of the 19th century, although the prerequisites appeared much earlier. unit. It is difficult to imagine a kitchen without a device that preserves food freshness, but two centuries ago humanity made do with glaciers and cellars. The answer to the question of when the first refrigerator was created goes back to the 19th century, although the prerequisites appeared much earlier.
The history of refrigeration is not just linear progress, but a series of brilliant insights, dangerous experiments and gradual improvement of technology. More than half a century of hard work by scientists and engineers from all over the world has passed from the use of natural ice to the creation of autonomous systems with compressors. It is this evolution that has allowed us today to enjoy ice cream in the middle of a hot summer.
The predecessors of electricity: the era of glaciers
Before the advent of electrical appliances, the main way to preserve food was natural ice. For centuries, people have built special storage facilities - glaciers, where snow and ice were transported in winter, carefully insulating it with sawdust and straw. In the summer, supplies melted, but allowed the food to be kept in acceptable condition for several months. It was a labor-intensive activity available mainly to the wealthy or communities with developed infrastructure.
In the mid-19th century, “refrigerated cabinets,” which were wooden boxes with double walls, began to appear in the United States and Europe. Insulating material was placed between the walls, and a huge piece of crushed ice was placed inside. The melt water was collected in a special pan, which had to be emptied regularly. Such devices were called iceboxes, and they became the direct ancestors of modern refrigerators.
- ❄️ Ice was delivered by special “ice carriers”, and its shortage in winter could lead to spoilage of food in summer.
- 🪵 The cases were made of oak or pine, often coated with zinc or tin for better thermal insulation.
- 💧 The main problem was the high humidity inside the chamber, which led to the rapid proliferation of bacteria, despite the cold.
⚠️ Attention: The use of open pieces of ice in residential areas created a risk of flooding and mold development if the melt water drainage is not monitored.
An interesting fact about the ice trade
In the 19th century, there was a whole industry for the extraction and transportation of ice. Ice from the lakes of New England was even sent to India and Australia on sailing ships, where it was preserved for months thanks to its dense packaging in sawdust.
Scientific discoveries and first experiments with cooling
The foundation for the creation of artificial cold was laid by physicists who studied the properties of gases and liquids. The key point was the discovery that when liquids evaporate, they absorb heat from the environment. In 1755, Scottish chemist William Cullen demonstrated the first artificial refrigerator, using a pump to create a vacuum over a container of ether. The water in the vessel froze, but this installation did not find practical application at that time.
In 1834, American Jacob Perkins received the first patent for a vapor-compression refrigeration machine. His device operated on a cycle that is still used today: compression, condensation, expansion and evaporation of the refrigerant. Ether was used as a working fluid. Although Perkins's machine was more of a laboratory prototype, it proved that it was possible to create a continuous cooling cycle without constantly adding ice.
Later, in the 1850s, French physicist Edmond Carré created an absorption refrigerator that ran on a mixture of water and ammonia. Its design was simpler in design, as it did not require moving mechanical parts such as pistons. However, ammonia is toxic and has a strong odor, which made the use of such devices inside homes extremely dangerous.
- 🧪 Early refrigerants such as ammonia, sulfur dioxide and methyl chloride were toxic or explosive.
- ⚙️ The first compressors were bulky steam engines that required the constant presence of an operator.
- 🌡️ Temperature control was carried out visually or by touch; thermostats appeared much later.
1913: the appearance of the first home electric refrigerator
It is 1913 that is considered the official date when the first refrigerator for home use, powered by electricity, was created. A model called DOMELRE (Domestic Electric Refrigerator) was presented by the American engineer Fred W. Wolf. This device no longer required the purchase of ice and worked completely autonomously, using an electric motor to drive the compressor. However, the revolution was made by the company that released the model in 1927. This refrigerator became the first mass product that could be seen in ordinary homes. The compressor and engine were located on top of the housing, which provided good ventilation but created significant noise. The device cost about $700, which by standards was equivalent to the cost of a car.
However, the revolution was made by the company General Electric, which released the model in 1927 Monitor-Top. This refrigerator became the first mass product that could be seen in ordinary homes. The compressor and engine were located on top of the housing, which provided good ventilation but created significant noise. The device cost about $700, which by standards was equivalent to the cost of a car.
Despite the high price, demand was growing. People appreciate the opportunity to not depend on ice supplies and get a consistently low temperature. The design Monitor-Top was so reliable that many copies worked for decades. This proved that the technology was ripe for mass adoption, and other manufacturers began to actively copy and improve GE's development.
| Year | Event | Significance |
|---|---|---|
| 1834 | Jacob Perkins Patent | First vapor compression machine |
| 1913 | DOMELRE model | The first electric home refrigerator |
| 1927 | GE Monitor-Top | Start of mass production |
| 1930 | Discovery of freon | Safe refrigerant for everyday life |
Safety and mass production: 1930s
The main obstacle to the widespread use of refrigerators remained safety. Early models often leaked, releasing toxic gases, causing accidents. The situation changed dramatically in 1930, when researchers at the company (a division of GM) synthesized dichlorodifluoromethane, known to the world as Frigidaire (a division of GM) synthesized dichlorodifluoromethane, known to the world as Freon-12. This substance was non-flammable, odorless and non-toxic in small concentrations.
With the advent of a safe refrigerant, the production of refrigerators reached a new level. Companies Westinghouse, Kelvinator and Electrolux began to produce more compact and quiet models. The price of devices began to decline, making them affordable for the middle class. In the 1930s, refrigerators began to be equipped with the first primitive thermostats, which made it possible to regulate the cooling intensity.
During the same period, the design changed. While the models resembled wooden cabinets, the new refrigerators featured sleek metal casings, often painted white or cream. Rounded shapes and chrome details have become a symbol of progress and modernism. Models with a separate freezer appeared, although initially it was just a small compartment inside the main volume.
- 🛡️ Freon made it possible to remove bulky and dangerous mechanisms from living rooms to basements or kitchens without risk to health.
- 🔌 Electrification of rural areas under the New Deal programs in the United States accelerated the penetration of refrigerators into farmers' houses.
- 📉 By the end of the 1930s, the cost of a refrigerator had dropped to $200, which made it a really salable commodity.
⚠️ Attention: Despite the safety of freon for humans in case of leakage, it was later discovered that these gases destroy the ozone layer, which led to their ban at the end of the 20th century century.
Post-war boom and technological race
After the Second World War, a real boom in the production of household appliances began. Defense technologies such as new alloys, efficient insulators and precision mechanics have been adapted for civilian use. Refrigerators have become a must-have in every kitchen in developed countries. The race for convenience began: automatic defrosters, interior lighting lamps and shelves with adjustable heights appeared.
In the 1950s, the company General Electric introduced the model Monitor Top already in an updated form, and competitors introduced new functions. The most important stage was the emergence of freezers of sufficient volume to store food for months. This changed the culture of consumption: people began to buy products less often, but in larger quantities. The industry of frozen semi-finished products appeared.
In the Soviet Union, mass production of refrigerators began later. Famous ZIL and Saratov became symbols of reliability. The first Soviet models often copied American models, but adapted to local conditions and power shortages. They were heavy, noisy, but extremely durable. Many of them are still working today, which indicates the high quality of assembly of that time.
- 🇺🇸 In the USA, by 1955, 90% of households already had refrigerators.
- 🇷🇺 In the USSR, mass production began with the ZIL plant in the 15th microdistrict of Moscow in the late 1950s.
- 🧊 The appearance of the system No Frost in the 1970s finally freed users from the need for manual defrosting.
☑️ Evolution refrigerator functions
Modern technologies: from inverters to smart homes
Since the end of the 20th century, development has followed the path of energy efficiency and intelligent control. The advent inverter compressors made it possible to abandon the constant switching on and off of the engine. Now the motor runs continuously, but changes the rotation speed, maintaining the temperature with an accuracy of 0.1 degrees. This has reduced energy consumption and noise levels to a minimum.
Modern models are equipped with multi-flow systems, where cold air is supplied to each point of the chamber separately, preventing over-drying of products. New refrigerants are used, such as isobutane (R600a), which are environmentally friendly. The appearance has also transformed: glass panels, touch displays and integration with Smart Home systems have become the norm.
Today, the refrigerator can order milk itself when it runs out, or send a notification to your smartphone if you forgot to close the door. Zoning technologies allow you to store meat, vegetables and wine at different temperatures in one volume. Progress from a piece of ice in a wooden box to a digital device with artificial intelligence took just over 100 years.
When did plastic appear in refrigerators?
Plastic began to actively replace metal in the interior of refrigerators in the 1960s. This made it possible to reduce the weight of the shelves, making them more hygienic and cheaper to produce. Before this, enameled metal grilles and shelves were used.
Why were old refrigerators louder?
The main cause of noise was piston compressors without sound insulation and the lack of vibration-damping mounts. Modern compressors are often immersed in oil or use a linear drive, which makes their operation almost silent.
Is it still possible to buy a refrigerator with manual control?
Yes, simple models (often called “tablet” or minibar) are still equipped with mechanical thermostats. They are considered more reliable in conditions of unstable network voltage, since there is nothing to burn in them except the thermostat itself.
What is the average service life of a modern refrigerator?
Manufacturers claim a service life of 7-10 years, however, with proper care and timely replacement of seals, modern units can operate for 12-15 years. The key factor in longevity is the quality of the compressor and the cleanliness of the condenser.
Are old refrigerators with freon harmful?
If the tightness of the circuit is not broken, the old freon is safe for residents. The only danger is a leak in an unventilated area, although high concentrations are required for poisoning. The main problem is environmental damage during disposal.
