摘要：
A ventilator and a moisture-removing air circuit system (100) thereof. A first solenoid valve (130) of the moisture-removing air circuit system (100) is mounted on an air outlet pipeline (124) connected to the outside； the two ends of a first monitoring pipeline (150) and a second monitoring pipeline (160) are respectively in communication with a differential pressure generating apparatus (120) used for producing differential airflow pressure and a differential pressure type flow sensor (140)； an air capacitor (170) is in communication with the first monitoring pipeline (150) by means of a first connecting pipeline (240), is in communication with the second monitoring pipeline (160) by means of a second connecting pipeline (250), and is in communication with an air supply apparatus (110) by means of a third connecting pipeline (260)； a second solenoid valve (180) is set up on the third connecting pipeline (260)； when the air pressure value detecting by a pressure sensor (190) reaches a preset air pressure value, the second solenoid valve (180) closes； when a patient exhales, the air capacitor (170) discharges air to prevent the air exhaled by the patient from flowing toward the first monitoring pipeline (150) and the second monitoring pipeline (160). The present moisture-removing air circuit (100) can effectively prevent the problem of condensation forming in the monitoring pipelines, and the moisture removing process is safer.L'invention concerne un ventilateur et son système de circuit d'air d'élimination d'humidité (100). Une première électrovanne (130) du système de circuit d'air d'élimination d'humidité (100) est montée sur une conduite de sortie d'air (124) reliée à l'extérieur ； les deux extrémités d'une première conduite de surveillance (150) et d'une seconde conduite de surveillance (160) sont respectivement en communication avec un appareil de génération de pression différentielle (120) utilisé pour produire une pression de flux d'air différentielle et un
