More specifically, a plurality of differential pressure sensors can be installed at both ends (i.e., the front end and the rear end) of the target filter to measure the differential pressure of the target filter. In this case, the differential pressure means a pressure difference between the front end and the rear end of the target filter, and the initial differential pressure refers to a value measured for the first time using a plurality of differential pressure sensors at the initial stage of the target filter installation.

That is, the differential pressure measuring unit 110 measures the pressure difference between the one end (for example, the front end) of the target filter into which the unfiltered air flows and the other end (for example, the rear end) of the target filter from which the filtered air flows The initial differential pressure can be obtained by measuring the pressure at the front end and the rear end of the target filter through a plurality of differential pressure sensors provided respectively and calculating a difference between the measured pressures.

The filter state determination unit 120 can determine whether the initial pressure difference provided from the differential pressure measurement unit 110 is within a predetermined reference differential pressure range.

If the initial differential pressure is within the reference differential pressure range, the filter state determination unit 120 may recognize the state of the target filter as a normal state and may not provide a separate signal to the alarm unit 130.

On the other hand, if the initial differential pressure is not within the reference differential pressure range, that is, is smaller than the minimum value of the reference differential pressure range, or is greater than the maximum value, the filter state determination unit 120 determines that the target filter is in the abnormal state And can provide the first operation signal to the alarm unit 130. [0033] FIG.

The filter state determiner 120 may receive the re-measured initial differential pressure from the differential pressure measuring unit 110 after providing the first operation signal to the alarm unit 130. [

If the initial differential pressure is not within the reference differential pressure range, the filter state determiner 120 recognizes the target filter as a defective state 2 operation signal to the alarm unit 130.

The alarm unit 130 may provide alarm information to the user according to the state of the target filter. For example, the alarm unit 130 may provide the alarm information to the user if the target filter is in an abnormal state, and may not provide any additional information if the target state is normal.

In this case, the alarm information may include first alarm information for requesting confirmation of whether the target filter is properly installed, and second alarm information indicating that the target filter is defective when the target filter is erroneously mounted.

In addition, the alarm unit 130 may receive the operation signal from the filter state determination unit 120 and provide alarm information corresponding to the operation signal to the user.

That is, if the first operation signal is received from the filter state determination unit 120, the alarm unit 130 may display the first alarm information to the user. If the second operation signal is received from the filter state determination unit 120, The second alarm information can be displayed to the user.
