Abstract

L'invention divulgue une structure d'évacuation appliquée à un climatiseur de type à selle et un climatiseur de type à selle. Le climatiseur de type à selle comprend une unité intérieure, une unité extérieure et une structure de pont de selle, et la structure de pont de selle peut s'étendre et se rétracter. Une conduite d'échange de chaleur comprend un ensemble de tuyaux de retour d'air et un ensemble de tuyaux de surfusion, et l'ensemble de tuyaux de retour d'air ainsi que l'ensemble de tuyaux de surfusion pénètrent à travers une cavité interne de la structure de pont de selle. L'ensemble de tuyaux de retour d'air et l'ensemble de tuyaux de surfusion sont chacun pourvus d'un tuyau d'évacuation. Des points à double position sont adoptés pour évacuer la conduite d'échange de chaleur, de telle sorte que le temps d'évacuation est raccourci, et l'efficacité de production est améliorée.
