Abstract

UNIDADE TROCADORA DE CALOR E UMIDADE. Uma unidade trocadora de calor e umidade (HME) (50) incluindo um alojamento (52), um meio de retenção de calor e umidade (meio HM) (54) e um mecanismo de válvula (56). O alojamento (52) forma uma seção intermediária (62) que se estende entre duas portas (58, 60) e que define primeiro e segundo caminhos de fluxo. O meio HM (54) é mantido ao longo do primeiro caminho de fluxo. O mecanismo de válvula (56) inclui um membro de obstrução (100) retido de maneira móvel dentro do alojamento (52) e transicionável entre os primeiro e segundo pontos máximos opostos de deslocamento. No primeiro ponto máximo de deslocamento, o membro de obstrução (100) fecha o segundo caminho de fluxo para permitir fluxo de ar através apenas do primeiro caminho de fluxo. No segundo ponto máximo de deslocamento, o membro de obstrução (100) permite fluxo de ar através de ambos primeiro e segundo caminhos de fluxo. A unidade HME (50) é simples de usar e ainda proporciona um estado de desvio eficaz em que o fluxo de ar avança livremente ao redor do meio HM (54).
