In life, people's requirements for the living environment are becoming more and more stringent, and they begin to pay more and more attention to the ambient air quality around them. Many people use the API to judge the quality of the air in their environment. So what is the air pollution index? Where did it come from?
Through the use of the Internet of things, GIX geographic information, mobile Internet, big data, environment model, such as technology, build a comprehensive perception of information based environment, environment quality conditions of pollutant emissions, environmental factors to conduct a comprehensive perception, real-time acquisition and automatic transmission, dynamic, comprehensive grasp park environment pollution and environmental quality status, implementation to strengthen environment
As we pay more and more attention to physical health, various factors affecting the body will be gradually understood by everyone. Among them, there is air quality. How do you know about air quality? Open various weather apps and you will always see an Air Quality Index (AQI) to indicate the recent air quality. What does it represent? And where does it come from?
Three meals a day, fry fry, five thousand years of food culture...... "Cooking" has already penetrated into everyone's daily life. Chinese food culture has a long history, which is one of the characteristics of Chinese civilization.
Mechanical ventilation type biogas releasing torch is fully automatic biogas releasing equipment. The torch is forced to shorten the flame by high volume air distribution, and the high volume air distribution can reduce the temperature of the combustion chamber. Biogas is decomposed and burned through low temperature oxidation reaction, and the by-products of combustion are CO2 (carbon dioxide) and H2O (water). Under the condition of low temperature combustion, can reduce NOx (nitrogen), SOX (su
Building Automation System (BAS) realizes remote automatic monitoring of mechanical and electrical equipment such as ventilation, air conditioning, water supply and drainage in the station, so as to realize centralized management and resource sharing. Under normal circumstances to create a good and comfortable riding environment, reduce energy consumption; Ensure safe evacuation of personnel under abnormal circumstances.
