Efeito Joule-Thomson – coeficiente de Joule Thomson<\/h2>\n

As mudan\u00e7as de temperatura durante o processo de estrangulamento est\u00e3o sujeitas ao \u00a0\u00a0efeito Joule-Thomson<\/strong>\u00a0.\u00a0\u00c0 temperatura ambiente e press\u00f5es normais, todos os gases, exceto hidrog\u00eanio e h\u00e9lio,\u00a0esfriam<\/strong>\u00a0durante a expans\u00e3o do g\u00e1s.\u00a0O resfriamento ocorre porque \u00e9 necess\u00e1rio trabalhar para superar a atra\u00e7\u00e3o de longo alcance entre as mol\u00e9culas de g\u00e1s, \u00e0 medida que elas se afastam.\u00a0O efeito depende do valor do\u00a0coeficiente de Joule-Thomson<\/strong>\u00a0, que \u00e9 definido como:<\/p>\n

Uma aplica\u00e7\u00e3o do processo de estrangulamento ocorre em refrigeradores de compress\u00e3o de vapor, onde uma\u00a0v\u00e1lvula de estrangulamento<\/strong>\u00a0\u00e9 usada para reduzir a press\u00e3o e reduzir a temperatura do refrigerante da press\u00e3o na sa\u00edda do condensador para a press\u00e3o mais baixa existente no evaporador.<\/p>\n<\/div>\n<\/div>\n
