Problems solved by technology

However, these two methods do not take into account the specific outdoor air quality. When the air quality is too poor, although the preset use time limit of the system has not been reached, the actual filtering capacity of the filter has reached the limit, and the quality of the air entering the room Not up to the standard, when the air quality is good, replacing or cleaning according to the use time limit will obviously produce waste

Embodiment 1

[0037] Based on the outdoor air quality, the cumulative dust holding capacity A is calculated by the following formula:

[0038]

[0039] Among them, b is a constant, dt is the working time, k is the air volume coefficient, the air volume is different, the k value is different, and P is the dust content in the intake air under the current air quality.

[0040] In this embodiment, because the product of the air volume and the dust content in the air intake needs to be calculated, in this embodiment, the air volume corresponds to the air volume coefficient, so the present invention provides three methods for confirming the air volume coefficient:

[0041] 1. The processing capacity of the filter screen is a fixed value by default in the system. In the present invention, the initial purification rate of the filter screen is set to 90%. Therefore, different fresh air volumes correspond to different air intake volumes, which are preset in the system Different fresh air volume ge...

Embodiment 2

[0048] Considering the impact of outdoor air quality and indoor air quality on the filter, the cumulative dust holding capacity A is calculated by the following formula:

[0049]

[0050] Among them, b is a constant, dt is the working time, k is the air volume coefficient, when the air volume is not constant, the value of k is different, k1 is the fresh air volume coefficient, k2 is the intake air volume coefficient, P1 is the real-time data of outdoor air quality parameters, and P2 is the indoor Ambient air quality real-time data.

[0051] In this embodiment, P1 is the real-time data of the outdoor air quality parameter, and the confirmation method is the same as that in Embodiment 1, and will not be repeated here.

[0052] P2 is the real-time data of the air quality of the indoor environment. A fresh air air quality detector can be installed in the fresh air fan to use the real-time data of the air quality of the fresh air to obtain the dust content in the fresh air. An ...

Abstract

The invention provides a new wind machine filter screen life control method. The method comprises: calculating air volume and dust content in real time, and then performing integral operation with accumulated time, finally obtaining real-time accumulated dust holding capacity of a filter screen, and comparing with a basic parameter which is preset by a system, determining the accumulated dust holding capacity of the filter screen in real time according to use conditions, to prompt filter screen cleaning or replacement in time. Through the accurate accumulated dust holding capacity calculationand comparison, the filter screen cleaning or replacement cycle meets combined technical life, maintenance time is more reasonable, and cost waste is prevented.

Description

technical field [0001] The invention relates to a method for controlling the life of a filter screen, in particular to a method for controlling the life of a filter screen of a fresh fan. Background technique [0002] In more and more fresh air system applications, there are pollutant filtration systems, such as the service life of the filter screen, and the conventional treatment is usually to clean or replace the filter screen regularly to ensure the filtering effect during the operation of the fresh air system . Generally speaking, the manufacturer will give a fixed replacement period, or through the accumulated working time, when the usage time limit is reached, the fresh air fan system will automatically prompt that the filter screen needs to be cleaned or replaced. However, these two methods do not take into account the specific outdoor air quality. When the air quality is too poor, although the preset use time limit of the system has not been reached, the actual filt...
