Description

A kind of indoor biological oxygenation subtracts carbon method and system
Technical field
The invention belongs to room ventilation technical fields, more specifically, be related to a kind of indoor biological oxygenation subtract carbon method and System.
Background technique
Carbon dioxide CO2, colorless and odorless, its usually imperceptible concentration, is that mankind or animal aerobic respiration is discharged A kind of exhaust gas is a kind of asphyxiant gas, is one of the major pollutants in room air.The source of indoor carbon dioxide includes Two kinds of indoor and outdoors.Outdoor source includes the burning etc. of coal and timber, and mainly there are two aspects in indoor source, first is that coming from human body The gas generated is breathed out, second is that the burning (heating of house coal stove, gas burner etc.) from fuel.The occurrence quantity of carbon dioxide is by people Or the quantity and activity condition of animal determine, such as in library and in sports ground, the average discharge amount of carbon dioxide of crowd Several times can be differed.
International research is often with carbon dioxide, as air quality and the primary evaluation index of ventilation state.To eliminate Most of to complain, indoor carbon dioxide total amount should be down to outdoor horizontal hereinafter, i.e. 1000ppm or less.It is promulgated according to China national " indoor air quality national standard " (GB/T18883-2002) in explicitly point out, the standard value of indoor carbon dioxide is 0.10%, that is, it is no more than 1000ppm.In Hong Kong, Environmental Protection Administration is that indoor air quality index has been formulated in office building and public place, Wherein carbon dioxide content is considered as good lower than 1000ppm.US Occupational Safety is thought with health research institute (NIOSH) It is a mark that gas concentration lwevel, which is more than 1000ppm, in room air, shows deficiency in draught.In U.S.'s ASHRAE ventilation standard Setting: it is recommended that 1000ppm is also not to be exceeded in indoor carbon dioxide concentration value.School's standard regulation of Britain, all teaching and 1500ppm is not to be exceeded when being sitting in height of head and in a whole day average measurement in the carbon dioxide for practising space.
When people is in indoor environment, constantly breathing needs constantly consumption oxygen.If dirty without enough fresh airs and interior Turbid air is swapped and is filtered, and the concentration of the foul atmospheres such as indoor carbon dioxide will rise, and long time integration gets off unfavorable In the physical and mental health of indoor crowd.It is chronically at the carbon dioxide environment of high concentration, harm is same fearful.Such as: the U.S. is two Aoxidizing influence of the concentration of carbon to people also has correlative study, and in " environment and health are looked forward to " (Environmental Health Perspectives research achievement has been delivered on): under closed environment, the carbon dioxide of people around's exhalation gathers may The thinking speed of people is set to become slower.
Carbon dioxide delay is the same with anoxic, is a dedicated pathology noun, can cause respiratory dysfunction, occurs one Range of clinical performance.Thus while properties of carbon dioxide is stablized, itself is nontoxic, but when carbon dioxide content is excessively high, can also make one Suffocate because of anoxic, or even dead.Surrounding air carbon dioxide is excessively high, and the not effective remedial measure of oxygen uptake changes Kind ventilation, help reduce surrounding air carbon dioxide.Single oxygen uptake, itself improves blood oxygen pressure, then this and while one Determine the discharge that carbon dioxide is inhibited in degree.
In large-scale indoor enclosure space, different spaces often can all have a different flows of the people, e.g. underground shopping plaza, Subway station or other places that can not mostly open a window again through ordinary person, and these places are generally mechanically taken a breath, ventilation quantity is Fixed, but stream of peoples' variation in these places is generally presented apparent cyclically-varying feature, this periodicity is when different Between can also difference under scale: observed as unit of day, we can see that the fluctuation of population from morning to night daily；With Zhou Weidan Position observation, we can see that the notable difference on working day and weekend；It is observed as unit of year, then can see four seasons weather and section again Influence of the holiday to flow of the people.It can be seen that if taking a fixed ventiduct roadbed in large-scale indoor enclosure space, Its deficiency in draught when people is more of very big chance, just in waste of energy when people is few.
