Tech & Beyond: The Kerosene Refrigerators of 1950s to 1970s, A Forgotten Innovation.
Introduction
During the mid-20th century, a unique technological solution emerged in response to the limited availability of electricity in developing countries like India: the kerosene-powered refrigerator. From the 1950s to the 1970s, these refrigerators became an essential household appliance, especially in rural and remote areas where reliable power infrastructure was scarce or nonexistent. Kerosene refrigerators, though largely forgotten today, played a crucial role in preserving food and medical supplies in areas where traditional electric refrigeration was not feasible.
Kerosene Refrigerators: How They Worked
Kerosene refrigerators operate on the principle of absorption refrigeration, a technology first developed in the 19th century. Unlike traditional refrigerators, which use an electric compressor to circulate coolant and lower temperatures, kerosene refrigerators utilized a heat source to drive a chemical reaction. The burning kerosene produced heat, which was then used to circulate ammonia gas through a network of tubes. As the ammonia evaporated, it absorbed heat from the interior of the refrigerator, cooling it down.
This system had the advantage of not requiring any electricity to function, making it ideal for regions where electric grids were underdeveloped or nonexistent. In fact, the kerosene refrigerators were designed to maintain a temperature range of 2-8 degrees Celsius, which is critical for preserving perishable goods and medical supplies like vaccines. However, maintaining this temperature consistently proved difficult, particularly in hot climates like India’s, where ambient temperatures could fluctuate widely.
The Role of UNICEF in Spreading Kerosene Refrigerators
The 1960s marked a significant period of geopolitical change and development in Asia. The Indo-Chinese War of 1962 highlighted the need for improved infrastructure and humanitarian aid, especially in remote areas. UNICEF stepped in by providing kerosene refrigerators to help store vaccines and other medical supplies in India. The need for temperature-sensitive vaccines during this time could not be overstated, as immunization programs were essential for combating diseases in rural areas.
Manufactured in Sweden by the Electrolux brand and later produced in India by Video Industries, kerosene refrigerators became a lifeline for many households and health facilities. However, due to the challenges in maintaining a stable internal temperature, the reliability of these refrigerators was often compromised. As vaccines are particularly sensitive to temperature changes, the storage of medical supplies in kerosene refrigerators presented risks that led to the search for better alternatives.
The Global Context: Electrification and Alternatives
The challenges posed by kerosene refrigerators were not unique to India. In fact, even in developed countries like the United States, widespread access to electricity was not guaranteed until well into the 20th century. By 1925, only half of American homes had access to electricity, and many rural areas remained off the grid for decades longer. As a result, developing countries without a reliable power supply turned to kerosene refrigerators as a practical solution.
However, as global electrification efforts gained momentum in the latter half of the 20th century, alternative refrigeration technologies began to emerge. By the 1970s, the drawbacks of kerosene refrigerators — their inefficiency, the difficulty in maintaining a consistent temperature, and their reliance on a fossil fuel source — spurred the development of solar-powered refrigeration systems.
The Solar-Powered Replacement
By the late 20th century, solar-powered refrigerators emerged as a game-changing innovation, particularly for areas without access to a consistent electrical grid. These refrigerators were designed to power the compressor directly using solar panels, eliminating the need for batteries or electricity from traditional sources.
Solar refrigeration proved far superior in maintaining a consistent temperature, an important factor for storing temperature-sensitive vaccines. The advent of solar-powered systems effectively replaced kerosene refrigerators in remote areas, offering a cost-effective, sustainable, and environmentally friendly alternative.
Solar-powered refrigerators are especially advantageous in countries with abundant sunlight, like India. Their use dramatically improved the efficiency of medical supply storage, enabling vaccines to be kept safely for longer periods, even in the most remote regions. These systems significantly reduced the dependency on kerosene, which was not only a costly and finite resource but also one that contributed to environmental pollution.
The Rise of Indian-Made Refrigerators
While the kerosene refrigerators distributed by UNICEF were foreign-made, the 1950s also marked the beginning of domestic refrigerator production in India. The first Indian-made refrigerator was produced by Godrej in 1958, marking a pivotal shift towards local manufacturing in the appliance sector. However, early Indian-made refrigerators had their own set of challenges. Heavy doors made them physically demanding to operate, and they were often less reliable than their foreign counterparts.
Foreign brands, such as General Electric (GE), which was a popular brand in North America, continued to dominate the market, especially for specialized needs like vaccine storage. For many years, UNICEF and other international aid organizations continued to supply foreign-made refrigerators to developing countries, favoring reliability and performance over locally produced alternatives.
A Transition to Modern Refrigeration
As the decades passed, and electricity became more widely available in India and other developing countries, kerosene refrigerators were gradually phased out in favor of electric models. The shift was part of a broader global trend toward modernization and improved infrastructure, which saw reliable power grids reach more and more areas.
Today, kerosene refrigerators are relics of a bygone era, replaced by energy-efficient, smart refrigerators that are not only easier to use but also environmentally friendly. Modern refrigerators are more accessible, affordable, and sustainable than ever before, with options like solar-powered systems still being used in the most remote parts of the world where electricity remains a luxury.
Conclusion
The kerosene refrigerators of the 1950s to the 1970s served as a vital solution to the problem of refrigeration in regions with limited or no access to electricity. Though primitive by today’s standards, these appliances helped ensure the preservation of essential items like food and vaccines, making a significant contribution to rural development and public health. While solar-powered refrigerators have since replaced kerosene models, and electricity is now the primary source of power for refrigeration, the role that kerosene refrigerators played in shaping the modern world should not be forgotten. Their legacy is one of innovation, resilience, and adaptation in the face of significant challenges.
