CONTROL METHOD FOR REDUCING RADON IN SOIL

摘要

The present invention relates to a method for controlling airflow variable soil exhaust radon reduction, comprising the steps of: (a) determining whether the radon concentration value measured by at least one radon measurement unit among a plurality of radon measurement units exceeds a preset reference radon concentration value; , (b) When the radon concentration value measured from any K-th radon measurement unit exceeds the reference radon concentration value, the K-th damper unit is controlled to open at a preset reference opening rate (O) and at the same time, the soil exhaust fan Performing a first control mode for controlling the operation to be operated for a preset operating time at the preset reference operation rate (P), and (c) performing the first control mode, Kth for a preset reference radon concentration reduction time Determining whether the radon concentration value measured from the radon measurement unit is reduced by a preset average reduction rate of radon concentration; performing a second control mode for controlling the K-th damper part to be further opened by a preset increased opening rate from the current opening rate; By including the step of repeatedly performing the 2 control mode, it is possible to effectively reduce radon in the soil entering the room by discharging the radon in the soil out of the building.
