Indoor air quality intelligent control system

Abstract

The invention discloses an indoor air quality intelligent control system, which comprises a fresh air unit, a circulation unit and a mixing unit, wherein the fresh air unit is provided with a first fresh air fan, an auxiliary heater, a fresh air filter and a second fresh air fan, the circulation unit is provided with a circulation air filter and a circulation fan, the mixing unit is used for realizing the mixing of outdoor fresh air and indoor circulation air, electromagnetic purification modules are respectively arranged in the fresh air filter and the circulation air filter, all modules are respectively connected onto a driving circuit, the driving circuit is connected with a main controller, and an air quality sensor, a temperature and humidity sensor, a PM2.5 sensor, a carbon dioxide sensor, a press key input circuit and an LCD (liquid crystal display) display circuit are respectively connected onto the main controller. The indoor air quality intelligent control system has the effects that the regulation and control of the outdoor fresh air and the indoor circulation air are integrated, the structure of the system is simple and novel, the arrangement is compact, the installation is convenient, the treatment on the indoor air can be realized, the air quality can be ensured according to requirements, the harm to human bodies caused by outdoor pollution can be reduced, and the energy consumption is reduced.

Description

technical field [0001] The invention belongs to the technical field of air quality control, in particular to an indoor air quality intelligent control system. Background technique [0002] The quality of air quality reflects the degree of air pollution, which is judged according to the concentration of pollutants in the air. Air pollution is a complex phenomenon, and the concentration of air pollutants at a specific time and place is affected by many factors. The emission of man-made pollutants from stationary and mobile pollution sources is one of the most important factors affecting air quality, including vehicle, ship, and aircraft exhaust, industrial enterprise production emissions, residents' living and heating, and waste incineration. Urban development density, topography and weather are also important factors affecting air quality. [0003] According to the "Ambient Air Quality Standards" (GB3095-2012), only 40.9% of the cities meet the standards; only 23.9% of the ...

AI Technical Summary

Problems solved by technology

[0004] Based on the above description, the air in the outdoor environment is uncontrollable, while the indoor space is relatively closed and can be controlled under certain conditions, but the indoor space has endogenous pollution and exogenous pollution. The source cannot be purified, and it can only be isolated and closed in the living space. After a long time, it will be hypoxic

However, the current ventilation or air treatment equipment has only a relatively single function, such as an air conditioner basically only has a temperature adjustment function, an air purifier basically only has an air purification function, and a humidifier basically only has a humidification function, and it is difficult to solve indoor problems. Air quality problems, it is also difficult to solve the problem of indoor hypoxia
