Real-time monitoring can be realized by intelligent monitoring equipment, which can monitor the polluted gas, pollutant index, air quality and even noise and humidity index around users.
6. What are the physical factors related to indoor air quality?
Temperature, relative humidity, wind speed and fresh air volume will all affect indoor air quality. Temperature and relative humidity will affect the thermal comfort of human body. Human thermal comfort refers to people's conscious satisfaction with the thermal environment.
7. What are the chemical factors related to indoor air quality?
Chemical factors include sulfur dioxide, nitrogen dioxide, carbon monoxide, carbon dioxide, ammonia, ozone, formaldehyde, PM2.5, PM 10, TVOC and lead. The standard of PM2.5 comes from American EPA standard, 0.0 1.5 mg/m3.
8. What is the object of indoor real-time monitoring?
Indoor monitoring method depends on the accuracy of monitoring sensor. At present, the commonly used parameters that can be accurately monitored are: PM2.5, PM 10, TVOC, CO2, temperature and humidity. Formaldehyde is a well-known pollutant, however, there is no accurate sensor to monitor formaldehyde in real time.
9. What are the installation requirements of real-time monitoring equipment?
It is suggested that the real-time monitoring equipment should be installed at the height of human breathing, that is, 750- 1800mm from the ground. The equipment should be away from openable windows, air filters and fresh air outlets.
