Abstract

본 발명은 공조기기의 필터막힘 감지장치에 관한 것으로, 종래에는 실제 필터막힘 여부와는 관계없이 송풍팬의 동작시간으로 필터막힘상태를 판단하였기 때문에 설치장소의 환경이 다르더라도 항상 똑같은 시기에 필터교환시기를 알려준다. 따라서 각 환경에 맞는 정확한 필터막힘을 감지할 수 없는 문제점이 있었다. 본 발명은 이러한 종래의 문제점을 해결하기 위해 송풍팬의 알피엠이 필터의 막힘정도에 따라 다르다는 것에 착안하여 송풍팬의 알피엠을 검출하여 이를 정상상태의 알피엠과 비교함으로써 필터막힘을 감지할 수 있어 공조기기의 설치환경에 맞는 정확한 필터막힘을 감지할 수 있는 공조기기의 필터막힘 감지장치를 창안한 것이다.The present invention relates to an apparatus for detecting a filter clogging of an air conditioner. In the related art, the filter clogging state is determined by the operation time of the blower fan regardless of whether the filter is actually clogged. Tell me when. Therefore, there was a problem that can not detect the exact filter clogging for each environment. The present invention focuses on the fact that the AlpM of the blowing fan is different depending on the degree of clogging of the filter in order to solve the conventional problems. It is the invention of the filter clogging detection device of the air conditioning equipment that can detect the exact filter clogging for the installation environment of the.
