Embodiment Construction
[0023] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.
[0024] With the reduction of the service life of the car air conditioner filter, although the purification effect of the car air conditioner has not changed much, as the dust on the filter gradually increases, the ventilation volume gradually decreases, which reduces the purification speed of the air in the car. Specifically, refer to figure 1 , figure 1 It is a comparison table of classification efficiency, pressure drop and ash storage capacity of the automobile filter screen of the present invention in different dust holding stages. From figure 1 It can be seen that the higher the dust holding stage, the smaller the ventilation volume of...

The invention relates to a detection method and device for service life of a filter screen, and particularly relates to a detection method and device for service life of an automobile air conditioner filter screen. The invention aims to realize the purpose of accurately detecting the service life of the automobile air conditioner filter screen. In order to realize the purpose, the detection method provided by the invention comprises the following steps: acquiring a PM2.5 value of the air in an automobile in real time; acquiring the duration that the PM2.5 value of the air in the automobile reaches a stable state according to the PM2.5 value of the air in the automobile; and calculating the service life of the automobile air conditioner filter screen according to the duration that the PM2.5 value of the air in the automobile reaches the stable state. The method for calculating the service life of the automobile filter screen is based on a mathematical model between the duration that the PM2.5 value of the air in the automobile reaches the stable state and the service life of the automobile air conditioner filter screen, wherein the mathematical model is characterized in that data is acquired by tests, and then the mathematical model is established for measurement results by Matlab for simulating, thereby determining an optimal algorithm. Therefore, the method is capable of accurately calculating the service life of the automobile filter screen, thereby accurately reminding a customer of replacing the filter screen.
Description
technical field [0001] The invention relates to a method and a device for detecting the service life of a filter screen, in particular to a method and a device for detecting the service life of an automobile air conditioner filter screen. Background technique [0002] With the deterioration of the environment, people pay more attention to the air quality in the car. More and more vehicles are equipped with HEPA filters to improve the air in the car. However, when the HEPA filter is approaching or reaching its service life, the purification effect will become worse, and it will even pollute the air in the car again. Therefore, users need to replace the HEPA filter in time before it reaches the end of its service life, so as to maintain good air quality in the car. [0003] At present, the user is reminded to replace the filter screen in time mainly through the use time of the air-conditioning filter screen of the car or the mileage of the vehicle. Due to the great differen...
