The history of artificial refrigeration dates back to long before the appearance of household appliances familiar to us in the kitchen. When the first refrigerator came out, humanity had no idea that this unit would forever change the food industry and the quality of life of every family. The first experiments on freezing water and cooling air were carried out back in the 18th century, but full-fledged devices capable of maintaining a stable temperature appeared much later.
The first commercially successful models that could be installed in a private home began to appear at the turn of the 19th and 20th centuries. Until this point, people had been using glaciers for centuries, cutting down blocks of ice in winter and storing them in deep cellars covered with sawdust. The invention of a mechanical method for producing cold was a real revolution, comparable to the invention of electricity or the internal combustion engine.
In this article we will examine in detail the chronology of events, from the first scientific discoveries to mass production. You'll learn what hazardous substances were used in early systems and why modern freons are considered safer, despite environmental controversy. Understanding the history of the device will help you better understand the principles of its operation and the causes of possible malfunctions.
Background: from glaciers to the first experiments
Before engineers were able to create a machine that produces cold, humanity relied exclusively on natural resources. Natural ice they were delivered from the mountains or frozen reservoirs and stored in special storage facilities, resembling thermoses. This system worked for centuries, but was seasonal and dependent on climatic conditions, which made storing food in summer extremely difficult.
The first scientific attempts to create artificial cold date back to the middle of the 18th century. In 1755, Scottish professor William Cullen demonstrated an experiment in which he used a pump to create a vacuum over a container of ether. The evaporation of the liquid under reduced pressure led to rapid cooling and the formation of a small amount of ice. Although this was only a laboratory experiment, it laid the foundation for understanding the physics of the process.
At the beginning of the 19th century, the American Oliver Evans described the theoretical vapor compression cycle, which formed the basis for the operation of all modern compressor refrigerators. However, Evans himself never built a working prototype. The honor of realizing the idea went to the doctor John Gorey, who in 1851 demonstrated a machine that used air compression to produce ice. His device was bulky and inefficient, but it worked.
Why did ice remain the main refrigerant for so long?
The extraction and transportation of natural ice was established on a huge scale. There was a whole industry of “ice farms,” and the transition to mechanical cooling required a complete restructuring of the infrastructure, which slowed down implementation.
1800s: the emergence of the first industrial installations
The middle and second half of the 19th century became a period of active experiments with various refrigerants. Engineers were looking for substances that could effectively absorb heat during evaporation. The first major step was the creation of a machine powered by ether, which was designed by Jacob Perkins in 1834. His device was called a "freezer", although in essence it was more a demonstration of principle than a practical tool.
In the 1850s, the French physicist Edmond Carré and his brother Ferdinand created an absorption refrigerator powered by water and ammonia. Ammonia installations proved so effective that they began to be used for industrial ice production and refrigeration breweries It was ammonia that became the first refrigerant to become widely used commercially, although its toxicity made use in residential buildings impossible.
By the end of the century, the first attempts to create a device for home use appeared. In 1879, Carl von Linde introduced a compressor refrigerator powered by methyl ether. This device became the forerunner of modern units, but its cost was astronomical for the average person. Such machines were installed mainly on ships for transporting meat from Australia to Europe.

The beginning of the 20th century: the first household electric models
The real boom in household refrigeration began in the first decades of the 20th century, when electricity began to penetrate middle-class homes. In 1913, the company Domelre (DOMestic ELectric REfrigerator) introduced a device that could be plugged into a wall outlet. However, it consisted of a separate compressor, which had to be installed outside the house or in the basement, since the noise and vibration levels were too high for a living room.
The turning point came in 1918, when the company Vigor (later renamed Frigidaire and bought by General Motors) began mass production of refrigerators with compressor located in the housing itself. This device became the standard of Indriya. In the 1920s, such giants as General Electric and Westinghousejoined the race, which led to lower prices and increased reliability.
Despite electrification, many households for a long time used “iceboxes” - insulated cabinets where imported ice was delivered. The transition to electric models has been slow due to the high cost of electricity and the units themselves. It was not until the 1930s that the electric refrigerator ceased to be a luxury item and became a mass product in the United States and Europe.
⚠️ Attention: Early models of the 1920s and 30s often used sulfur dioxide, methyl chloride and ammonia as refrigerants. These substances are poisonous and explosive. If you are restoring an antique refrigerator, do not under any circumstances try to start its old system - this can be deadly.
The evolution of refrigerants: from ammonia to freon
Safety has become the main driver of changes in the design of refrigerators. In the early 1930s, an accident occurred at the Cleveland Clinic, where a toxic refrigerant (sulfur dioxide) leaked and resulted in death. This incident has forced the industry to look for a safer alternative. The company's chemists General Motors i DuPont synthesized a group of substances known as freons (chlorofluorocarbons).
Freon-12 (R-12) became a revolutionary solution. It was non-toxic, non-flammable and odorless. This made it possible to place the compressor and the entire piping system directly inside the kitchen cabinet, making the refrigerators compact and safe to install in the kitchen. From that moment on, the design of refrigerators began to change, becoming more streamlined and aesthetic.
However, at the end of the 20th century, it became clear that freons destroy the Earth's ozone layer. This led to the 1987 Montreal Protocol and the phasing out of CFC refrigerants. They have been replaced by HFCs (hydrofluorocarbons) such as R-134a, which are ozone-friendly but have a high global warming potential. Today, the industry is returning to natural refrigerants such as isobutane (R-600a), which was used in the earliest experiments, but now in safe microdoses.
Modern refrigerators often use a mixture of gases or new synthetic substances with minimal environmental impact. Engineers have to balance between energy efficiency, fire safety and environmental friendliness.
Comparison of cooling technologies: then and now
Over a hundred years, technology has stepped far forward. While the first models required constant maintenance and had extremely low efficiency, modern units operate for years without human intervention. The main difference lies in the accuracy of temperature control and defrosting system.
The table below compares the key characteristics of the first electric models of the 1920s and modern devices:
| Characteristics | Models of the 1920s-30s | Modern models (2020s) |
|---|---|---|
| Refrigerant | Sulfur dioxide, Methyl chloride | Isobutane (R-600a), Propane |
| Control | Mechanical thermostat | Electronics, Wi-Fi, AI |
| Defrosting | Manual only (shutdown) | Automatic (No Frost) |
| Noise | Very high (audible in the next room) | Quiet (< 40 dB) |
Modern compressors have become inverter. Unlike old motors that operated in the “on-cool-off” mode, the inverter smoothly regulates the rotation speed, maintaining the temperature without jumps. This significantly saves energy and extends the service life of the equipment.
⚠️ Attention: When purchasing spare parts for repairing old refrigerators, make sure that the oil in the system is compatible with the type of refrigerant. Mineral oils (for freons) and synthetic oils (for new gases) cannot be mixed - this will lead to capillary blockage and compressor failure.
Design and functionality: how the appearance has changed
The appearance of refrigerators has also undergone enormous changes. The first models resembled wooden cabinets with metal cladding. In the 1930s and 40s, during the era of Art Deco and streamline moderne, refrigerators became round, chrome-plated and often painted in bright colors: turquoise, pink, mint. They were the centerpiece of the kitchen.
After World War II, white color and rectangular shape became the standard. The interior space has also evolved, with separate freezers, tempered glass shelves, freshness zones and ice makers. Today the first refrigerator with a touch screen and access to the Internet will not surprise anyone, although this function still remains a niche.
An important stage was the appearance of the system No Frost in the 1970s. Before this, housewives were forced to regularly defrost the unit by chipping off the ice with a knife. The introduction of forced air circulation relieved users of this responsibility, although it created new challenges, such as increased drying of products, which is solved by modern humidification systems.
☑️ Signs that the refrigerator requires replacement
Frequently asked questions (FAQ)
When exactly did the very first refrigerator appear in the world?
If we talk about the industrial prototype, then 1851 (John Gorey). The first household electric refrigerator appeared in 1913 (Domelre), and mass production began in 1918 (Frigidaire).
Why were old refrigerators so noisy?
Compressors of early models were open-type, operated at high speeds and did not have high-quality sound insulation. In addition, refrigerants that required high pressure were used, which increased the vibration of the pipelines.
Is it still possible to find refrigerators that run on ammonia?
Yes, ammonia absorption refrigerators are still produced, but mainly for motorhomes, hotels (silent minibars) and places where there is no electricity (run on gas). In ordinary apartments they are almost never used due to the risk of leakage.
Who invented the No Frost system?
The principle was developed by General Electric engineers in the late 1940s, but it began to be used en masse in household models only in the 1970s.
Understanding when the first refrigerator came out and how it evolved provides context for assessing the reliability of modern technology. Engineers have gone through a long journey of trial and error so that today we can simply open the door and take a chilled product without thinking about the complex physical processes occurring inside.
