Abstract

"TROCADOR DE CALOR DE LINHA DE SUCçãO PARA SISTEMA DE RESFRIAMENTO A CO~ 2~". Um trocador de calor incluindo uma linha de sucção (74) para refrigerante gasoso ou bifásico extraído de um evaporador (28) e um tubo capilar (60) que porta refrigerante resfriado para o evaporador. A linha de sucção inclui uma primeira e uma segunda porções cilíndrica retas substancialmente paralelas conectadas em série, com a primeira e a segunda porções do tubo capilar em série e enroladas de forma helicoidal em torno da segunda e primeira porções de linha de sucção, respectivamente. Uma válvula (64) para criação de um by-pass do tubo capilar responde a um diferencial de pressão selecionado entre a entrada e a saída de tubo capilar. Uma porção em formato de U ou acumulador conecta as primeira e segunda porções de tubo capilar. Um acumulador alternativamente está entre o evaporador e a porção de linha de sucção enrolada pelo tubo capilar, com uma câmara de separação de fase conectada a um acumulador por um tubo vertical. O acumulador inclui uma abertura de descarga para retorno do óleo para o sistema.
