Celebrating 26th June World Refrigeration Day

26 June 2020

The need for refrigeration in order for people to continue their vital activities is invaluable to consider today's conditions. Well in the past; Without the mechanical systems used now, the question arises of how people kept their food…

Throughout human history, all of the inventions evolved over time and took their present form. In the old days, food and drinks that had to be kept cold were kept in the ice packs to keep them cold. Of course, it was essential to reinforce the ice floes at regular intervals. However, this was mostly possible in the winter. For the summer, the snow collected in the winter months was stretched and stored in caves. Thus, the inside of the cave was used as a cold storage room and kept in food. On the other hand, the rooms that do not see the sun and are relatively cooler compared to other rooms were used as cellars.

Apart from these, old wire cabinets should not be forgotten. These cabinets were used for the purpose of gathering and gathering rather than storage and used for dried meat, vegetables and fruits with different methods. Of course, I can not go without talking about the canning method, which has not lost its popularity even now. Our mother canned food, which feels like it is in the middle of summer in the winter, also played a role here. In the past, salting was considered one of the conservation methods. Soil jugs were used for cold water storage.

The first known artificial refrigerating method was applied by William Cullen at Glasgow University in Scotland in 1756. Cullen used a pump to create a partial vacuum in the diethyl ether tank. In this way, ice could be obtained, but it could not be continued as a practical method.

In the mid-1800s, ice was an export product for the USA. Ice was regularly shipped to the Caribbean and to South America as a good commodity. In the first half of the 19th century, this became a serious business for the USA. Known as the "Ice King", Frederic Tudor of New England worked on thermal insulation products to transport ice over long distances with ships. In 1805, American inventor Oliver Evans designed but failed to produce a vapor compression refrigeration cycle.

In 1820, British scientist Michael Faraday developed a system with high pressure and low temperature liquid ammonia and other gases. In 1834, Jacob Perkins patented the first refrigeration cycle. James Harrison patented the first commercial ice machine in 1854.

As of today, the use of refrigerators in homes is around 1911. As you can see, although the story of cooling has been since the creation of humanity, it is only 250-300 years ago that we try to realize it and use it.

There is a brand new, bright generation ahead of us for years and sectoral development. I hope their work will be our hope. I would like to take this opportunity to congratulate the whole refrigeration community on June 26, World Refrigeration Day, and hope that it will be freely celebrated next year without any restrictions.
