(FR) DISPOSITIF DE MESURE DE COLMATAGE DE FILTRE DANS UN ÉQUIPEMENT DE CLIMATISATION, ET ÉQUIPEMENT DE CLIMATISATION
(JA) 空調設備のフィルターの目詰まり測定装置および空調設備
Abstract:
(EN) 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).
(FR) La présente invention concerne un dispositif de mesure qui mesure avec précision le colmatage d'un filtre au moyen d'un mécanisme simple. Dans un équipement de climatisation (2) comprenant un ventilateur (30) qui souffle un gaz (40), (42) à travers un conduit (10) et un filtre (20) qui est disposé dans le conduit (10) et qui piège la matière flottante dans le gaz, ce dispositif de mesure de colmatage comprend : un dispositif de mesure de pression acoustique (26) disposé à l'intérieur du conduit (10) ; un dispositif de traitement de données (70) pour extraire des données de pression acoustique pour une fréquence spécifique à partir de données pour la pression acoustique mesurée par le dispositif de mesure de pression acoustique (26) ; et un dispositif d'estimation (70) pour estimer le colmatage du filtre sur la base des données de pression acoustique pour la fréquence spécifique telles qu'extraites par le dispositif de traitement de données (70).
(JA) [要約] 簡便な設備で正確にフィルターが目詰まりを測定できる測定装置を提供すること。目詰まり測定装置は、ダクト(10)を通じて気体(40)、(42)を送風するブロワ(30)と、ダクト(10)に配置され、気体中の浮遊物を捕捉するフィルター(20)とを備える空調設備(2)において、ダクト(10)内に設置された音圧測定器(26)と、音圧測定器(26)で測定された音圧データから特定周波数の音圧データを抽出するデータ処理装置(70)と、データ処理装置(70)で抽出された特定周波数の音圧データに基づき、フィルターの目詰まりを推定する推定装置(70)とを備える。 [選択図]図2
