When the first refrigerators appeared in the world: a complete history

The history of artificial refrigeration of food goes back millennia, long before humanity discovered electricity. First attempts Keeping food fresh without the use of natural ice dates back to the mid-18th century, but mass production of household devices began only at the beginning of the 20th century.

The key moment was the invention of the compression cycle, which made it possible to create a closed cooling system. General Electric is considered the first mass-produced household refrigerator “Monitor-Top”, released in 1927. This date is often considered the starting point of the era of home refrigeration, although experimental models existed earlier.

The path from bulky, noisy and dangerous units to modern smart systems took almost a century. You will find out how refrigerants changed, why early models exploded and how engineers managed to make cold accessible to every family.

Predecessors of electricity: ice cabinets

Before the advent of electric units, the main way to store food was Icebox an insulated cabinet, where imported natural ice was periodically placed. Such devices appeared in the middle of the 19th century and were actively used until the 1930s.

The design was simple: the upper chamber was filled with blocks of ice, which melted, cooling the lower shelves with products. The melt water was collected in a tray, which required regular manual cleaning. It was labor-intensive, but effective for its time.

Efficiency depended on the quality of the insulation of the cabinet walls. Materials such as cork, sawdust and zinc were used. Temperature conditions in such cabinets it rarely fell below +4°C, which allowed food to be stored for only a few days.

The era of experimentation: the first mechanical installations

The first prototypes of mechanical refrigerators appeared in the second half of the 19th century. Engineers tried to recreate the natural cycle of liquid evaporation in a closed loop. One of the pioneers was an American physician John Goreywho in 1844 created an ice-making machine using air compression.

Later, in the 1870s, a German engineer Carl von Linde developed the first effective ammonia compressor machine. These units were huge and intended exclusively for industrial use in breweries and meatpacking plants.

⚠️ Warning: Early refrigerants such as ammonia and sulfur dioxide were toxic and explosive. A leak of such gas in a living room could lead to tragic consequences, so domestic implementation was delayed for decades.

By the beginning of the 20th century, engineers had learned to create more compact systems, but they still required manual winding or connection to gas networks. Electric motors were rare and very expensive back then.

1910s: the birth of the electric refrigerator

The real breakthrough came in 1913, when the company General Electric introduced the first electric refrigerator for home use. The model was called Audiffren-Singrun and worked on sulfur dioxide.

The device was extremely noisy: the compressor was located directly in the living room, and not in an isolated block. In addition, the system required constant maintenance and refilling with refrigerant.

In 1915, Alfred Mellowes created a prototype, which later became known as Frigidaire. He pioneered the concept of a “refrigerator in a cabinet,” where all the mechanical parts were hidden inside the cabinet. This has become a design standard for many years.

1920s: reaching the masses and safety

The twenties were the decade when refrigerators began to appear in the homes of wealthy Americans and Europeans. The main obstacle remained the safety of refrigerants.

In 1927, General Electric released the model Monitor-Top. It got its name from the distinctive cylindrical shape of the compressor located on top, which resembled a monitor warship. This device became the first truly reliable unit.

• ❄️ The refrigerant SO2 (sulfur dioxide) was used, which was still dangerous, but the sealing system became more reliable.
• 🔌 The first built-in thermostats appeared, allowing you to set the desired temperature.
• 🔇 The compressors became quieter, although the hum was still audible throughout the apartment.

By the end of the decade, there were already about a million refrigeration units in the United States. A technology race began: manufacturers competed in the efficiency of insulation and the volume of freezers.

Freon revolution and the post-war boom

Hereby The salvation of the industry was the invention of Freon (R-12) in 1928 by Thomas Midgley. This gas was non-flammable, odorless and safe for humans in case of leakage. However, mass introduction occurred only after World War II.

In the 1930s, refrigerators began to be equipped with completely hermetic compressors. This solved the problem of leaks and made it possible to place the unit in the kitchen without fear of poisoning. In 1939, the company General Electric introduced the first two-chamber model.

After 1945, mass production began. The refrigerator has ceased to be a luxury item and has become a necessity. Automatic defrosters and more efficient door seals have appeared.

Modern refrigerators use isobutane, which is more environmentally friendly than freon, although it requires special fire safety measures during production. Technologies have stepped far forward, but the principle of operation of the compressor remains the same.

Evolution of defrosting and control systems

For a long time, owners had to regularly defrost the refrigerator manually, unplugging it from the network and waiting for the ice to melt. It was inconvenient and time-consuming.

In the 1960s, the system No Frost (without frost) appeared. It allowed dry, cold air to circulate, preventing the formation of ice crystals on the walls. At first, the technology was used only in freezers, later - throughout the entire volume.

Modern models are controlled electronically. You can set freshness zones, fast freezing modes, and even diagnose faults via your smartphone. Inverter compressors work quietly and economically, smoothly adjusting power.

⚠️ Attention: If you own a vintage refrigerator from the 60-70s, do not try to replace the refrigerant with a modern analogue yourself. Oils and seal materials in old equipment are incompatible with new gases.
