Esta disserta¸c˜ao deve gerar quatro artigos a serem publicados em congressos e revistas internacionais. O primeiro artigo ´e sobre a meto- dologia de controle chaveado desenvolvida e testada experimentalmente e foi submetido ao CDC1 2014. O segundo artigo deve ser uma vers˜ao
mais detalhada do primeiro e ser´a submetido a uma revista especiali- zada em controle. O terceiro artigo trata da compara¸c˜ao das t´ecnicas de controle desenvolvidas, com o foco nos resultados de refrigera¸c˜ao ob- tidos. O quarto artigo aborda o estudo realizado sobre a influˆencia da restri¸c˜ao dos dispositivos de expans˜ao em regime permanente e regime transit´orio sobre o sistema de refrigera¸c˜ao de duplo-evaporador. Estes dois ´ultimos artigos devem ser submetidos a revistas de refrigera¸c˜ao.
