VENTILATION SYSTEM FOR MONITORING OPERATION STATE IN REAL TIME

摘要

PURPOSE: A ventilation system is provided to monitors an operation state in real time by using a sensor. CONSTITUTION: A blower system includes a blower case having an air introduction port(30) and an outlet port(40), an impeller(60), and a sensor. The impeller(60) is arranged in the blower case. The sensor monitors the impeller(60). The blower system has an outlet port connected to a wasted gas processing device. The impeller(60) is connected to an electrical motor through a shaft passing through the blower case. The sensor monitors current supplied to the electrical motor. The sensor includes an optical sensor for detecting an operation of monitoring a rotation motion. The blower case is divided into a lower case(52) and an upper case(54).
