#STORIES: THE ORIGINS OF THE REFRIGERATOR
by Digital Marketing E. Online Marketing ProfessionalThe advent of mechanical refrigeration coincides with the invention of the steam compression machine: made by Jacob Perkins, he made his debut in 1834 and used ethyl ether. It is only a first step: the collective dream is to allow transport and storage of food on long journeys. Suffice it to say that at the time of the Republic of Venice, in order to defend food from the attack of ravenous mice, the sailors had only one weapon available: the cats!
Perkins' invention is followed by a series of attempts, experiments and small achievements. In 1857, Carrè first introduced an improved version of the compressor for ethyl ether, then an absorption refrigerating machine that uses, as a fluid, a mixture of water and ammonia.
The years pass. It is 1876. And in Argentina the crew of the Frigorique vessel faces an apparently invincible challenge: it must bring the meat of 600/700 cattle to France and no then known treatment (drying, smoking, salting) can guarantee conservation of foods for such a long journey (about three months). The solution is identified by Tellier, who creates a compression refrigerator of methyl ether and installs it on the ship. This invention has the scope of a real revolution: the air is cooled by the evaporator tubes, which maintain the constant temperature.
The following year, in Scotland, the Bell family patents an air-cooled system: mounted on the Dunedin, a sailing vessel, it runs on steam and allows you to transport frozen meat from New Zealand to London.
These are the first stages of the "conquest of the cold", the process that leads to the affirmation of the refrigerator and its undisputed success. Today, the fridge is one of the few appliances, among those present in our homes, to operate 24 hours a day. Continuous innovations have made it possible to make refrigerators more and more thrifty and efficient and less polluting. Their complexity, determined by the numerous components, sometimes leads them to need careful maintenance. Also for this Astelav Now offers a wide selection of spare parts for refrigerators : balconies, drawers, filters, gaskets, doors, handles, thermostats, electronic cards and much more ... available for immediate delivery.
