Primary air system air quality early warning method and device

Abstract

The embodiment of the invention provides a primary air system air quality early warning method and device. The method comprises the steps that environmental data of a primary air system are obtained;the purification efficiency and the heat exchange efficiency of the primary air system are obtained according to operation of the environmental data; judgment is carried out according to a preset purification efficiency threshold value or a preset heat exchange efficiency threshold value, and if the purification efficiency is lower than the purification efficiency threshold value or the heat exchange efficiency is lower than the heat exchange efficiency threshold value, an early warning command is sent out. The device comprises an obtaining module, a processing module and an early warning module. According to the embodiment, the purification efficiency and the heat exchange efficiency of the primary air system are calculated and judged, early warning information is generated, monitoring ofthe working efficiency of an air purification filtering element of the primary air system is achieved, early warning is carried out for prompting a user to replace the air purification filtering element, and the air quality of the primary air system is guaranteed.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an air quality early warning method and device for a fresh air system. Background technique [0002] In recent years, air pollution has become increasingly serious, resulting in frequent occurrence of air quality problems such as smog. More and more people start to pay attention to the quality of indoor living environment and outdoor air quality. Smog contains a large amount of PM2.5 particle pollutants. These harmful particles can directly enter the blood through the bronchi and alveoli without detoxification by the liver and dissolve in the blood, causing great harm to the human body. Moreover, these harmful particles not only exist in large quantities outdoors, but also in the indoor environment where people live. In addition, there will be a large amount of VOC (Volatile Organic Compounds, volatile organic compounds) and CO produced by human metabolism indoors. 2 and bact...

This consumes power and has not achieved the desired effect.

[0004] In the existing fresh air system using the air purification filter element, there is no monitoring of the purification efficiency of the filter element, making it difficult for users to judge the purification efficiency of the air purification filter element, and it is impossible to know whether the purification efficiency of the fresh air system has achieved the effect of air purification. The purification efficiency of the air purification filter element is too low, which makes the fresh air system unable to purify the air, reducing the air quality and affecting the health of users
