What people used before the refrigerator was invented?
Let’s push back the time to the days of hunter-gatherers and the notion of preserving food. For starters, It was literally eaten whatever food was hunted and obtained. However, as conditions changed and food hunting declined, individuals had to continue seeking ways to keep their food fresh and healthy. That’s when people began to pickle, smoke, and treat foods.
Icehouses were also constructed underground or as enclosed structures at different points in time, and were used to preserve ice and snow collected during winter, and keep food frozen during the summer months. Before the first century, ice was harvested and deposited in China.
The Idea & Technology development
The history of the refrigerator does not begin with the capacity of a metal box to generate cold air, it began thousands of years ago when people used several different cooling mechanisms to avoid spoiling their foods. Let’s explore the idea and the technology development of refrigerators in this time graph.
Who invented the refrigerator?
There are several pioneering scientists behind the invention of refrigerators.
|William Cullen||William Cullen, a Scottish physicist, developed the first method of artificial refrigeration. Cullen explained how cooling would occur from rapid heating of the liquid to a gas. This is the idea that still exists today behind refrigeration. According to Peak Mechanical Alliance, a plumbing and heating business based in Saskatoon, Saskatchewan, William Cullen demonstrated his theories by evaporating ethyl ether in a vacuum in 1748.|
|Oliver Evans||The next phase in 1805 was to reinvent a closed vapor-compression cooling mechanism based on ether, which had its boiling point diminished by vacuum, by the American inventor Oliver Evans. Before Jacob Perkins designed the first working vapor-compression refrigeration machine in the world in 1834, these innovations and prototypes were not practical. His machine had a locked loop and was able to run without waste.|
|John Gorrie||Although practical, economically, it did not succeed initially. In 1842, the American physician John Gorrie designed a working device and intended to use it in tropical homes to cool the air, but this one was also a commercial disappointment. A British journalist who immigrated to Australia, James Harrison, designed a manual ice-making machine in 1851 and designed the first industrial ice-making machine in 1854.|
|Carl von Linde||German scientist and engineer Carl von Linde established the process of liquefaction gas which was the crucial aspect of refrigeration technology. This lead to the first reliable and efficient compressed-ammonia refrigerator in 1876.|
The technological development of refrigerators continued in the late 1850s and progressed further in the 1900s.

Today, there are several types of refrigerators introduced in the market. Manufacturers are continually innovating to introduce emerging technologies styles, and functionality to consumers, looking beyond the icebox if you will. Here are some of the modern refrigerators available in the market.
|French Door Refrigerators||Situated at the top, the French doors provide plenty of room inside and store everything from large platters to pizzas. Plus, if you’re a bit of anal-retentive, they come in versions of 3, 4, and 5 doors, which you can organize to the content of your heart.|
|Side by Side Refrigerators||This design is definitely more your game if your food storage requirements are equal parts fridge and freezer. The entire height of the appliance is taken up by both the fridge and the freezer. There are fewer organizing choices than the 5-door French door model, but there is still a lot of wiggle space. For optimum versatility, there are flexible shelves and some versions also include some nifty options for door organizing.|
|Counter Depth Refrigerators||Counter-depth appliances have a shallow profile relative to most refrigerators. They don’t in short, stand out outside the counter. This gives them a smooth, built-in look that if you prefer both fashion and feature.|
|Compact Refrigerators||Many miniaturized models of conventional refrigerators are more than just a college indulgence, known for their dorm room appearance. They are fantastic for game rooms, home bars, or the workplace as well. A tiny freezer is found within several of them. The best advantage of these is location, position, location. There are many locations where they can travel, allowing you a great deal of versatility.|
|Wine Refrigerators||These refrigerators are primarily made for cocktails, drinks, and more to the point, for those who drink booze and wine. While they are mostly of the compact variety, you can even buy full-sized models and hundreds of bottles have space for them.|
|Chest Freezers||Chest freezers store a great deal of food, but they have a huge footprint as well. They are less likely to induce freezer burns because of their mechanics. Another advantage of their layout is how they keep the cold inside. They do not avoid the freezing weather as easily as they do for upright freezers.|
|Upright Freezers||There is a smaller physical footprint of these refrigerators than the chest freezer. They even have door storage that because of factors like gravity, the chest model does not. The design of these appliances has all the advantages, such as flexible shelving, that your fridge has.|
Most famous manufacturers
Manufacturers of refrigerators give different degrees of strength and special characteristics. Some versions, using higher wattage to get the job done, will hold loads of food longer. While some do not have as much ability, they still perform well. A lot really depends on your personal preferences, the room in your house, and any paint and design choices you have.
|Whirlpool||For their efficiency and consistency, Whirlpool refrigerators continue to get especially high marks in the market. Yale Appliance ranks them as the best for durability, which means out of all the top brands, Whirlpool refrigerators seem to have the least service calls.||LG||LG has concentrated on its refrigerator division, proving to be a professional manufacturer focused on high-tech technology and solid construction. they produce sleek fridges with spectacular smart Wi-Fi screens that also act as a refrigerator window, then LG offers some of the most impressive models available.||Samsung||High-tech fridges renowned for stylish stainless steel and Wi-Fi capability are made by Samsung. This is a product to try out if you want a refrigerator that really goes the extra mile with technology.||GE Appliances||Behind Whirlpool, in terms of reliability, GE appliances rank second best. GE refrigerators, cost-wise, are usually cheaper than rival versions with identical specifications.||KitchenAid||KitchenAid has a wide variety of appliances that range from must-have kitchen basics to more complex innovations. This company has years of experience manufacturing high-quality products, selling five-door versions with features such as herb-specific storage, temperature control, dual-cooling systems, and more.||Frigidaire||Usually, their refrigerators come with over-sized door shelves for easy storing of bottles and jugs, strategic positioning of lighting to help see inside, and customizable shelves for your desired custom setup.|
