Description
Technical field
The utility model relates to a kind of Indoor environment atmosphere quality monitoring device.
Background technology
Indoor air quality monitoring system is the product of Smart Home development, is a subsystem of Smart Home.In recent years along with growth in the living standard, people more and more pay close attention to relevant indoor air quality issues IAQ (IndoorAirQuality).IAQ has become the important component part in work and living environment.Room air pollution is problem day by day serious now, and consider that the time of people 90% is all at indoor activity (school, office, mechanism, commercial facility), IAQ (indoor air quality) is to health of people, comfortable and safe factor with strongest influence power.Room air pollution can cause Cure of Sick Building Syndrome (SBS) and building relevant disease (BRI).SBS Cure of Sick Building Syndrome is different with general disease symptoms, and be difficult to find specific pathogen, but leave in buildings, symptom can alleviate.But building relevant disease is by microbial contamination or specifically contacts the hypersensitive chemical substance that may cause and cause, even if leave in buildings, symptom also can not disappear.
The quality of room air depends on many factors, comprises the concentration of various gas and particulate pollutant.Deficiency in draught, the waste gas that enough outdoor airs can not be brought to carry out dilution chamber's presence of pollution sources discharge, thus increase room air pollution level.High temperature and high humidity also can increase the concentration of some pollutant.Utilizing ventilation to come dilution chamber's presence of pollution sources and air filtration, is maintain the good main method of IAQ (indoor air quality) in most of buildings.
The primary standard that U.S. environment protection mechanism (EPA) arranges CO is every 8 hours 9ppm.CO2 is ingredient common in air, and content is 330-400ppm.CO2 concentration is a good index of air-conditioning and construction ventilation rate, and the SBS symptom that CO2 is relevant comprises headache, unable, eye is done, schneiderian membrane and respiratory tract infection.Suspended particulate substance, also referred to as gasoloid, comprises organic chemicals, flue dust, dust, sour foam, metal and soil mishmash.
Have the particle of two groups of classifications to suck corase particles, such as other at railway and industry dusty is more common, the diameter of these particles than 2.5 microns greatly, is less than or equal to 10 microns.Another is fine particle, and diameter is less than or equal to 2.5 microns, is common in smoke and fog haze.The size of particle is directly connected to the potentiality that it causes health problem.Diameter 10 microns and following particle enter lung by nasal cavity, throat, once suck, these particles can affect cardio-pulmonary function, even bring health more adverse influence.PM10 can increase attack times and the order of severity of asthma, increases the weight of bronchitis and other pulmonary disease, reduces the resistivity of health, especially old man, children and trouble asthma and bronchitic Susceptible population.
Therefore study IAQ (indoor air quality) very important, design the health, comfortable and safe of a suitable indoor air quality monitoring phylogenetic relationship to daily life people.
