From the days of using natural snow and ice to cool food and drinks to the modern marvel of electric refrigerators, the history of refrigeration is a fascinating journey through time. Whether you have it at your home, restaurant, or grocery store, refrigeration has revolutionized how food is stored and preserved.
In this blog, our refrigeration maintenance service providers will take you through the history of refrigeration and how it works to help you better understand the technology that keeps your food fresh.
The History Of Refrigeration
The concept of refrigeration dates back to ancient times. Ancient cultures used basic techniques such as storing foods in cold water or snow to keep them cool and fresh. In 1758, Benjamin Franklin and John Hadley conducted experiments that showed that evaporation had a cooling effect. This led to more advanced methods like iceboxes that stored food in blocks of ice and insulated containers that could keep food cold for extended periods. However, these methods were inefficient and expensive.
The Modern Refrigerator
As technology has advanced, refrigerators have become much more energy efficient than before. In 1835, an American inventor named Jacob Perkins created the first working refrigerator using ammonia gas as a coolant. Other inventors improved upon his invention over the years until we got modern refrigerators with compressors, condensers, evaporators, and other components that create cold air inside the fridge while releasing heat into the environment outside the fridge.
How Refrigeration Has Changed Human History
The invention of refrigeration had a major impact on human history, especially regarding food storage and preservation. With fridges now commonplace in almost every home worldwide, people can store food for longer without worrying about spoilage or wastefulness. This has made it possible for us to eat fresh foods from all over the world year-round instead of being limited to seasonal fruits and vegetables grown locally. Additionally, refrigerated transport vehicles have allowed us to distribute perishable goods across large distances efficiently and safely.
How Does A Modern Refrigerator Work
It uses a fairly simple process involving circulating a coolant to absorb heat inside the unit and transport it outside. Inside the refrigerator, a fan circulates the air to keep temperatures consistent throughout.
The coolant evaporates as it absorbs heat from the interior, passes through a compressor where it is compressed, allowing for the release of more heat, and then condenses on tubes outside the refrigerator before returning inside to absorb more heat and start the process all over again. Without this cycle of travels through different stages, refrigerators wouldn’t be able to maintain cool temperatures that keep our food safe and make frosty beers.
