Air conditioner air duct dust accumulation amount monitoring system and method with early warning function

Abstract

The invention discloses an air conditioner air duct dust accumulation amount monitoring system and method with an early warning function. The monitoring system comprises at least two piezoelectric cantilever beam sensors, a detection integration unit and a control center; the at least two piezoelectric cantilever beam sensors are arranged in a detection air duct where an accumulated dust sampling point of a to-be-detected air conditioner is located, a first groove is formed in the inner wall of the bottom of the detection air duct, the first groove is used for containing one piezoelectric cantilever beam sensor, and the upper surface of a piezoelectric film of the piezoelectric cantilever beam sensor and the upper surface of the inner wall of the bottom of the detection air duct are positioned on the same horizontal plane; and the detection integration unit is in communication connection with the control center and each piezoelectric cantilever beam sensor. Online detection can be realized, and a result can be conveniently, rapidly and accurately obtained; and the system is simple, the sensors are small in size, the system is convenient to install, cleaning of the air duct is not affected, and building decoration is not affected.

Description

technical field [0001] The invention relates to the technical field of air-conditioning, in particular to a system and method for monitoring the amount of dust accumulated in an air-conditioning duct with an early warning function. Background technique [0002] The air conditioner is to maintain a suitable indoor temperature and humidity, and the air conditioner duct is an important part of the air conditioner system. During the operation of the air conditioner, dust will inevitably appear in the air duct of the air conditioner, which not only affects the air cleanliness of the air conditioner, but also promotes the breeding of mites, Legionella, E. coli, etc., pollutes the entire indoor air, and even spreads diseases. According to the survey results of air-conditioning health conditions released by the Chinese Center for Disease Control and Prevention, only 6.12% of the air-conditioning system ventilation ducts in more than 60 cities were tested for dust accumulation and du...

Problems solved by technology

Although this method is feasible, there will be some problems in actual operation: the restriction of the structure of the dust storage tank will affect the air flow of the air duct, resulting in distortion of the amount of dust on the surface of the dust storage tank, and at the same time affect the cleaning of the air duct; in addition, the system has a main shell The housing is also equipped with light-emitting components, photoelectric sensors, microprocessors, and wireless communication components. An oversized main housing is likely to conflict with the decoration style of the building and limit its application.
