Abstract

a presente invenção refere-se a um aparelho condicionador de ar que compreende: uma unidade externa que possui um compressor e um trocador de calor externo, uma unidade de interna que possui um trocador de calor interno, e tubulação de conexão de refrigerante líquido e tubulação de conexão de refrigerante a gás para conexão das unidades externa e interna; tubulação de refrigerante líquido externa, a qual conecta uma extremidade do lado do líquido do trocador de calor externo com a tubulação de conexão do refrigerante líquido, sendo provido com uma válvula de expansão e ajuste de pressão do líquido para descompressão do refrigerante de modo que o fluxo de refrigerante na tubulação de comunicação de refrigerante líquido entre em um estado bifásico gás-líquido; no qual o som anormal gerado a partir da unidade externa seja eliminado. a tubulação de conexão de refrigerante líquido (34) é provida com unidades de válvula de expansão (4a, 4b) conectadas externamente que possuem válvulas de expansão (71a, 71b) conectadas externamente para reduzir ainda mais a pressão do refrigerante que teve a pressão reduzida pela válvula de expansão e ajuste de pressão do líquido (26).
