Abstract

resumo patente de invenção: "ar condicionado". a presente invenção refere-se à desumidificação que não pode ser realizada quando a carga diminui. em um ar condicionado da presente invenção, um trocador de calor interno inclui um trocador de calor auxiliar (20) e um trocador de calor principal (21) disposto na direção do vento a partir do trocador de calor auxiliar (20). em uma operação em um predeterminado modo de operação de desumidificação, um fluido refrigerante líquido fornecido para o trocador de calor auxiliar (20) todo se evapora a meio-caminho no trocador de calor auxiliar (20). portanto, apenas uma área parcial a montante no trocador de calor auxiliar (20) é uma região de evaporação, ao mesmo tempo em que uma área a jusante da região de evaporação no trocador de calor auxiliar (20) é uma região de superaquecimento. no predeterminado modo de operação de desumidificação, um compressor e uma válvula de expansão são controlados de modo que a extensão da região de evaporação do trocador de calor auxiliar (20) varia dependendo da carga.
