Control method and system of fresh air system and fresh air system

Abstract

The embodiment of the invention provides a control method and system of a fresh air system and the fresh air system. The method includes the steps that environmental data is acquired, wherein the environmental data comprises indoor CO2 concentration and indoor PM2.5 concentration; according to a preset indoor CO2 concentration condition and a preset indoor PM2.5 concentration condition, whether the indoor CO2 concentration meets the CO2 concentration condition or not is judged, and whether the indoor PM2.5 concentration meets the PM2.5 concentration condition or not is judged; a control instruction for starting a working mode of the fresh air system is sent according to a judgment result. According to the control method and system of the fresh air system and the fresh air system, different working modes can be automatically started according to the real-time concentration of indoor and outdoor air quality parameters, so that air purification requirements under different air conditions are met.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a control method, a control system and a fresh air system 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 exist in large quantities in the indoor environment where people live. Moreover, there will be a large amount of volatile organic compounds (Volatile Organic Compounds, hereinafter referre...

Problems solved by technology

However, in the fresh air system using the air purification heat exchange core, since the high-voltage electric field is used to filter and purify the air, when the environmental data such as humidity in the air exceeds the standard, it will directly affect the discharge U and I data of the electric field , leading to safety hazards or malfunction of the fresh air system

In other existing fresh air systems or air purifiers that use high-voltage electrostatic methods to filter or purify air, there will also be problems with abnormal electric field voltage / current due to environmental changes

Therefore, the safety issue of the fresh air system with electrostatic purification has become a technical problem that cannot be ignored in the existing fresh air system using electrostatic purification.
