The operation principle of indoor roof mixed ventilation device: by CO
2sensor 11 is arranged in indoor occupant main activities district, and distance ground level is 1.0 ~ 1.5m place.Use CO
2cO in sensor 11 Real-Time Monitoring main room
2concentration, passes through CO
2sensor is by CO
2concentration is converted into the current signal of 4 ~ 20mA, and imports controller 10 into, judges indoor CO by corresponding software analysis
2whether concentration exceeds standard, and is controlled the keying of air-valve 3 and mechanical exhaust machine 4 by controller 10.Work as CO
2when concentration is higher than standard value, control air-valve 3 by controller 10 and mechanical exhaust machine 4 is opened, thus make indoor CO
