A invenção e a história do refrigerador

O que é um frigorífico?

É uma máquina de arrefecimento que funciona com o método de compressão de vapor, mantendo o alimento frio por um longo tempo.

 

Primeiro frigorífico mecânico:

O maior passo para fazer o frigorífico é o arrefecimento mecânico, que foi desenvolvido pelo britânico Thomas Harris e John Long em 1790, e também possuía a primeira patente conhecida para esse período. O refrigerante mecânico era similar à bomba da sucção-descarga e necessitou a mão-de-obra para operar. Embora o uso do aparelho é difícil para esse período, hoje em dia os frigoríficos ainda estão trabalhando com o método encontrado pelos dois inventores.

 

Primeiro refrigerador do pistão que funciona sem mão-de-obra:

Inspirado pelo mesmo dispositivo, o americano jackop Perkins patenteou uma máquina de refrigeração de pistão trabalhando com éter em 1834. Mas como o éter era inflamável e explosivo, o dispositivo era extremamente perigoso. Tomou seu lugar na história com o dispositivo que será inspirado para produzir refrigeradores modernos.

 

Primeiro frigorífico fabricado para fins comerciais:

Em 1844, John Gorrie fez o primeiro frigorífico produzido para fins comerciais. John Gorrie, um médico em sua profissão original, tomou o seu lugar na história como o pai de "sistemas de condicionamento de ar-refrigeração-produção de gelo comercial" em 1844.

 

Dr. Alexander Kirk desenvolveu o primeiro dispositivo de refrigeração de absorção que trabalhou com calor de carvão em 1861. A entrada no campo comercial da produção de gelo através de arrefecimento mecânico foi no final do ano 1800 ′.


 

O primeiro refrigerador que trabalha com energia elétrica:

Karl von Linde (1832-1934) introduziu a primeira geladeira do inventor alemão Linde para o mundo no ano 1876, trabalhando com energia elétrica. Para a circulação do gás, o compressor elétrico-psto foi usado para o sistema refrigerando e o éter metílico. Em 1877 ele recebeu patentes para este dispositivo. Era revolucionário trabalhar com a energia elétrica do dispositivo. No entanto, o éter metílico utilizado para o sistema de arrefecimento ainda era extremamente explosivo e não podia ser usado como modelos anteriores devido a preocupações de segurança. Apesar disso, ele conseguiu vender 747 geladeiras até 1890.

 

Revolução na geladeira, uso de gás Freon:

O sueco, Baltzar von cilindro (1898-1984), juntamente com Carl Munters, produziu o primeiro frigorífico a utilizar gás Freon. O gás éter utilizado em refrigerantes anteriores tem usado gás Freon, um novo acelerador, devido ao arrefecimento inadequado e risco de explosão. O dispositivo, que fornece um arrefecimento mais eficaz e nenhum risco de explosão, expirou como um marco na geladeira.

 

A primeira fábrica do refrigerador foi estabelecida:

Kelvinator Company foi fundada em 1914. Os frigoríficos, que são totalmente automáticos e têm uma função condensadora, foram produzidos em 1925. O primeiro ano foi uma empresa gigante, vendendo 67 peças de guarda-roupa, um total de 200 armários entre 1918-1920 anos.

 

Um armário de gelo automático que trabalha com o princípio da absorção foi liberado igualmente em América em 1927 pela companhia de Kelvinator de Electrolux.

 

A indústria ràpida em evolução e a diferença nos benefícios do refrigerador conduziram ao estabelecimento de muitas fábricas do refrigerador. Os produtores mais organizados e de trabalho de equipa asseguraram que os frigoríficos de hoje são revelados.
