Document Type and Number:
WIPO Patent Application WO/2019/009379
Kind Code:
A1
Abstract:
Provided is a measurement device that accurately measures clogging of a filter by means of a simple mechanism. In air-conditioning equipment (2) comprising a blower (30) that blows a gas (40), (42) through a duct (10) and a filter (20) that is arranged in the duct (10) and that traps matter floating in the gas, this clogging measurement device comprises: an acoustic pressure measurement device (26) arranged inside the duct (10); a data processing device (70) for extracting acoustic pressure data for a specific frequency from data for the acoustic pressure measured by the acoustic pressure measurement device (26); and an estimation device (70) for estimating clogging of the filter on the basis of the acoustic pressure data for the specific frequency as extracted by the data processing device (70).
