Vamos entender o funcionamento desses componentes:<\/p>\n<ul>\n<li><strong>Evaporador:<\/strong> No evaporador, a \u00e1gua refrigerante (ou outro fluido) evapora, baixando a temperatura do meio circundante. Esse vapor \u00e9 ent\u00e3o conduzido para o absorvedor.<\/li>\n<li><strong>Absorvedor:<\/strong> No absorvedor, o vapor de refrigerante \u00e9 absorvido por um l\u00edquido absorvente, criando uma solu\u00e7\u00e3o l\u00edquida rica em refrigerante. Esta solu\u00e7\u00e3o \u00e9 ent\u00e3o bombeada para o gerador.<\/li>\n<li><strong>Gerador:<\/strong> O gerador aquece a solu\u00e7\u00e3o, causando a separa\u00e7\u00e3o do refrigerante do l\u00edquido absorvente. O vapor de refrigerante \u00e9 direcionado para o condensador, enquanto o l\u00edquido absorvente \u00e9 reciclado de volta para o absorvedor.<\/li>\n<li><strong>Condensador:<\/strong> No condensador, o vapor de refrigerante \u00e9 condensado de volta para forma l\u00edquida.
