a ventilation system based on measurement of indoor and outdoor air quality

摘要

The present invention relates to an indoor ventilation system, and more particularly, it relates to an indoor ventilation system, in which indoor air quality and indoor outdoor air quality are measured simultaneously, and then indoor air quality and outdoor air quality are compared, and ventilation can be performed only when outdoor air quality is better than indoor indoor air quality. And more particularly, to a ventilation system based on indoor / outdoor air quality measurement that can prevent indoor air quality from being deteriorated and thus optimize indoor air quality. The present invention provides a ventilation system based on indoor air quality measurement, comprising: a slave measuring device for measuring outdoor air quality; an indoor air quality measuring device for measuring the indoor air quality, receiving outdoor air quality information from the slave measuring device, And a ventilator controller for ventilating the ventilator by driving the ventilator when it is determined that the ventilator needs to be ventilated by the master measuring device.
