METHOD FOR DETECTING BLOCKAGE IN EXHAUST FLUE OF GAS BOILER

Document Type and Number:

WIPO Patent Application WO/2015/163620

Kind Code:

A1

Abstract:

The present invention relates to a method for detecting a blockage in an exhaust flue of a gas boiler, comprising: (A) a step for conducting an ignition process according to a user setting temperature requested from the outside and performing temperature control to reach the user setting temperature; (B) a step for determining whether the current fan RPM of a driven blower exceeds a reference fan RPM; (C) a step for calculating a difference between temperature values of supplied heating-water and collected heating-water that are detected by temperature sensors when heating-water is supplied and determining whether the calculated value is less than a preset reference temperature value when it is determined that the current fan RPM exceeds the reference fan RPM; (D) a step for determining whether a preset setting time has elapsed based on the determination time point of the step (C) when it is determined that the calculated value is less than the reference temperature value; and (E) a step for displaying, to the outside, a notification that the blockage in the exhaust flue has been identified when it is determined that the setting time has elapsed based on the determination time point of the step (C).
