Hello! Today I am going to talk you about the invention of the refrigerator. I chose this topic because I think we all can’t imagine our lives without food, so we also can’t imagine our lives without the refrigerator. I’m going to present you this topic with the help of power point and I really hope that in the end of my presentation you will know something more about refrigerators. The invention of the refrigerator The conveniences we enjoy in our homes are the product of many machines we use every day to make our lives easier.
We must be aware that it is only because of dedicated inventors that have spent years of their life, searching of a way to make all this possible. We’re talking about machines such as the refrigerator, for example. The idea of a machine that would be able to prevent food spoilage has actually been around for a very long time before the invention of itself. It was only in the late 1834 that Jacob Perkins, a young inventor after making a design persuaded John Hague to realize his idea, and like that the first kind of refrigerator was born. Early attempts
In the beginning, there were made ice houses to provide cool storage for most of the year. These ice houses were placed near freshwater lakes or packed with snow and ice during the winter. As we can see in Thomas Jefferson’s diary, which chronicles the process of maintaining the ice house at the Monticello Estate, this processes were very complicated. Every winter, Jefferson brought more than 60 wagonloads of ice from the Rivanna River to keep his ice house filled. The ice house was a huge source of trouble, just by the expense of keeping it stocked.
The Essay on First Time People House Life
The first time event that I remember best is my first time in Blue Water. It was a life altering event for me, and I am thankful for it. I forgot what the most important thing in life was, and I became a bad person and I did bad things, in turn ended me up in jail. I have to admit it at first I was scared so bad I was sick to my stomach. I remember the thoughts that were going through my head. I ...
While Jefferson was busy keeping his ice house stocked, Benjamin Franklin working with chemist John Hadley in 1758 was leading us to the invention of the refrigerator. They were experimenting with the effects of evaporation using a thermometer. With some methods they were able to drop the thermometer’s temperature well below freezing. Perkins and his impact In 1834 a young inventor called Jacob Perkins build the world’s first refrigerator and invented a legal patent for refrigeration using vapor-compression.
Soon, what was meant to be just an experiment became something fit for commercialization and other inventors tried to develop Perkin’s patent. In 1856 following Perkins’ success, James Harrison, an immigrant from Scotland living in Australia, developed an ice making machine using ammonia and an ether compressor. It was used in the meat packing industries of Geelong, Victoria. Few years later, Carl Paul Gottfried Linde, a German engineer developed refrigeration and gas separation technologies.
Carl Paul Gottfried Linde (better known as Carl von Linde) was working in the way of develop new refrigeration cycles. In 1892 Linde’s research drove into the area of low temperature refrigeration and in 1894 he started work on a process for the liquefaction of air. In his later career Linde began working on a technique to obtain pure oxygen and nitrogen based on the fractional distillation of liquefied air. By 1910 Carl’s son Friedrich had developed the Linde double-column process, variants of which are still in common use when it comes to air separation in three main gasses: oxygen, nitrogen and argon.
CONCLUSION In the 1920s and ’30s, consumers were for the first time introduced to freezers – that was the time when the first electric refrigerators with ice cube compartments came on the market. Even so, the mass production of modern refrigerators didn’t get started until after World War II. Few decades later when innovations like automatic defrost and automatic ice makers first appeared, it became clear that more energy-efficient refrigerators are needed, if not, there will be a huge environmental damage.
The Essay on Refrigerator History Ice First Refrigeration
The first method of refrigeration used was to pack the desired item to be kept cold, in snow, ice, cool streams, springs, caves and cellars. Thousands of years ago, cellars were holes dug into the ground and lined with wood or straw and packed with snow and ice. Meat and fish were preserved by salting or smoking. In 1, 000 BC the Chinese cut and stores ice, and around 500 BC the Egyptians and ...
The conclusion soon leaded to the elimination of chlorofluorocarbons in refrigeration sealed systems and the introduction of energy-efficient refrigerators. Today, the refrigerator is America’s most used appliance, found in more than 99. 5% of American homes. We are all aware that if this invention had never been invented our lives would be much more complicated. For example the food spoilage would be 5 or 6 times quicker. Besides that, we would be still forced to store our food in ice houses. With this conclusion I end my presentation. I hope you enjoyed and thank you for your attention. =)
