Description
Technical Field
The utility model relates to an air purification technical field is an improve device of indoor air quality particularly.
Background
Utility model patent: a large tracts of land horizontal air supply formula air purifier, patent no: 201410124256.3, discloses an air sterilizer which adopts the principle of large-area horizontal air outlet and can reach the disinfection and sanitation standards of hospitals. The patent is used for carrying out an aerosol test in an environment cabin with 30 cubic meters, the efficiency of killing white grape bacteria can reach 99.9% -99.99%, but the patent mainly aims at bacteria in the air, has no specific effect on allergens, and also has no purification effect on gaseous pollutants such as formaldehyde and the like.
The above patent refers to an air cleaning device for a single air contaminant of a local environment, and does not relate to an overall improvement of indoor air quality to meet the requirements regarding internationally advanced indoor air quality.
As early as the late 70 s of the 20 th century, the expression "Indoor Air Quality (IAQ)" appeared in some western countries. At that time, the air tightness of the building is greatly improved in consideration of energy conservation, so that the indoor ventilation rate is insufficient, and the indoor air pollution event frequently occurs. Some people develop symptoms such as headache, dry cough, dry and itchy skin, dizziness, nausea, difficulty in concentrating attention and sensitivity to odor, and this condition called "sick building syndrome" occurs in many countries, and developed countries have tragic training in this respect. This has led to intensive research and study into the impact of indoor air quality on human health, pollutants and their sources, and feasible solutions.
In recent years, due to the introduction of air conditioning systems in modern buildings, the popularization of modern office equipment, and the improvement of building airtightness, harmful gases in rooms are not discharged, and the amount of carbon dioxide is increased, so that various sub-health states such as "air conditioning diseases" and "room syndrome" are generated. Now, indoor air purification research has become one of the most environmental concerns in the world.
Air purifiers used in living rooms, offices and public places in China are still in the market lead-in stage at present, although the air purifiers have a certain effect on controlling particulate matters, the air purifiers are limited by design concepts and design mechanisms, the problem of Indoor Air Quality (IAQ) cannot be effectively solved, and particularly the control on air allergens is blank.
The united states of america WELL proposed the air quality standards in buildings, and the indoor air quality management group of the government of special administrative districts in hong kong made "indoor air quality verification plans in offices and public places" and "guidance indexes for indoor air quality management". The above standards specify limit standards for the relevant pollutants in indoor air: PM (particulate matter)10Is 20 microgram/cubic meter, PM2.515 micrograms per cubic meter, 0.03 milligrams per cubic meter of formaldehyde, 800PPM of carbon dioxide, 0.05 micrograms per cubic meter of ozone, 500cfu per cubic meter of bacteria.
The carbon dioxide concentration is an important index of indoor air quality, and the general building environment can cause serious air quality reduction due to insufficient ventilation quantity. At present, the single air purification, air disinfection and air cleaning device is difficult to control the problem of the increase of the indoor carbon dioxide concentration. At present, the commercial fresh air machine introduces outdoor fresh air to improve the freshness of indoor air, but is difficult to control the indoor air quality, particularly difficult to control the problem of allergen existing in outdoor invasion and indoor environment, and the problem of energy consumption loss is very serious.
As is well known to those skilled in the art, airflow patterns have a very important impact on improving Indoor Air Quality (IAQ). The existing airflow organization has two modes, namely vertical laminar flow and horizontal laminar flow. But buildings in general do not have a pattern that uses laminar flow. The building laminar flow needs high investment of construction, special equipment layers and high energy consumption of operation. Most of the building environments in China have no strength to build and use the air device. The laminar flow cleaning device for the building also has the defects that gaseous pollutants cannot be controlled and the like.
Therefore, how to solveSolving the worldwide problem is always the goal of the science and technology personnel in the field. Namely, the method can improve Indoor Air Quality (IAQ), and can effectively remove allergens, microorganisms such as bacteria and the like, PM in the air10、PM2.5Gaseous pollutants such as particle pollutant, formaldehyde, TVOC, ozone, carbon dioxide reach the advanced standard's of indoor air quality device, and this kind of device can not produce secondary pollutant such as ozone, nitrogen oxide, can reduce noise, resistance again simultaneously, reduces the consumptive material, and ten minutes is energy-conserving simultaneously.
