Modern humanity often does not even have an idea of what history preceded the fact that we have a great opportunity to use refrigerators. It is so familiar and routine that our kitchen has this indispensable assistant. Today, buying a LG refrigerator or Samsung is not a big problem, because the choice of models in the modern household appliance market is very wide. To do this, you don’t even need to rush to a supermarket selling home equipment. It is enough to visit the website of the virtual store and choose the model you like. Even if the need for food cooling has existed from time immemorial, but only relatively recently people invented a machine that produces cold. Since the mid -nineteenth century, a compressor has been invented from the middle of the nineteenth century, which allowed to develop the cold. Before that, structures were used in which ice and snow existing in nature were preserved and used.
At the dawn of civilization.
In the southern countries such as Greece, Italy, France, snow and ice for cooling products and drinks were prepared high in the mountains. In the middle lane, like ours, ice was used, formed in the cold winter months of the year. He was sawn into blocks and he was placed in the so-called glaciers-cellars-bribes. In order not to melt the ice, it was hidden by a thick layer of straw, sawdust, spruce or pine needles. The cellars were under the thick cover of the earth and turf, which served as a beautiful natural heat insulator. Such primitive devices kept cold for hot summer months. At the same time, people had the opportunity to maintain perishable products for a long time. It was a way developed by centuries -old practice.
Luxury subject or relevant need?
Even in those days, the refrigerator could also serve as the subject of luxury. In rich families of Italian patricians or in Russian landowner estates in the summer hot months, wine bottles placed in a vessel filled with stabbed ice were served to the table. These were primitive and impromptu vessels, keeping the cold for some time, which were practically placed on the table along with the contents. For storage of perishable products, specially made cabinets filled with ice were also used. In order to ensure proper thermal insulation, the pieces of such cabinets were filled with sawdust, moss, and on the outside they were wrapped by animal skins, which are excellent natural heat insulators. A gutter was made in the lower department of the cabinet for the removal of water formed from the melting of ice. The content of such a refrigerator required constant care, and this was done by the servants.
Advantages of modern units.
All these difficulties have gone far into the past, and now they seem very primitive to us. Samsung, Atlant, Snaige refrigerators and freezers fell in love with such famous manufacturers. Technical progress supplied our homes with excellent equipment, which performs many functions even without our participation. It is enough to set the desired program, and “the process has gone”. This applies as washing machines or dishwasher, so the entire range of units available in our homes. After all, we set the desired cooling or freezing mode by just turning the thermostat regulator to the desired value. And about when to thaw, we can not worry at all, because the new models of refrigerators are equipped with an automatic thawing system. Truly progress serves a person!
