Description
Technical field
The utility model relates to indoor environment field of engineering technology, particularly indoor air purifier.
Background technology
Along with current economic and industrial fast development, the air pollution of China's most area is day by day serious.Except the indoor formaldehyde, escaping gas pollution etc. of long-standing problem, haze has become the daily hot topic talked about of people.During haze weather, air is flooded with a large amount of pellets---and PM10, PM2.5(PM10, PM2.5 refer to that in air, diameter is less than or equal to the fine particle of 10,2.5 microns).Wherein, PM2.5 can directly invade human body bronchiole and lung cells, directly affects the ventilatory function of lung, makes body easily be in anaerobic condition, therefore in the air quality how purifying the long-time movable interior space of people, the most important thing guaranteeing fitness-for-all is become.
At present, air purifier on the market mainly adopts active carbon adsorption technology, ozone purification technology, anion dedusting technology and high voltage electrostatic technique, but, these air purifiers can only remove the harmful substance in room air by the circulation of indoor closed, but cannot introduce fresh air.Although family formula central authorities VMC solves new wind problem, this family formula central authorities VMC has the following disadvantages:
1. pipeline runs through indoor ceiling, must burrow on wall or beam, must do furred ceiling and carry out hiding pipeline, and install inconvenience, take up room waste material, and increases windage;
2., in a set of house, a chamber ventilated is just a complete set of to ventilate, and causes and wastes, waste energy in uninhabited room;
3. open continuously the whole year by requirement abroad, waste energy, inactive then easily produce the secondary pollution of pipeline, not environmentally;
4., without filtering function or only have and slightly imitate filtration, for the more serious actual conditions of China's haze damage ratio, haze can not be reduced on the impact of IAQ;
5. when namely the principle of negative pressure of family formula central authorities its draft type of VMC works, indoor environment is in negative pressure state.And if human body is in subnormal ambient for a long time, the function of lung can be affected, reduce oxygen content in blood, cause in blood but oxygen, and then affect the vigor of brain.And the environment of negative pressure, easily outdoor contaminated air easily pours in down a chimney.
Comparatively advanced indoor air purifier, if publication number is the Chinese patent of CN103982949A, disclose the dual-purpose new wind air cleaner of a kind of anti-PM2.5 with ozone removal device, this clearing machine is by realizing the removal of PM2.5 in new wind channel setting pretreatment coarse filter component, particle electrification deduster, microparticle combine component, fine grained electrostatic precipitator etc.The defect that this air cleaner exists is: one, not to the function of PM2.5 particle Real-Time Monitoring, and user cannot the PM2.5 situation of the indoor environment of real-time awareness residing for it, and then can not take safeguard procedures effectively; Two, it is only provided with CO at main body inner surface
2detector, does not provide PM2.5 concentration and CO
2concentration is on the impact of equipment operation situation, and namely this indoor air purifier cannot according to CO
2concentration levels adjusts machine run situation.As everyone knows, when people is in CO for a long time
2in the environment that concentration is higher, damage is had to people's brain; Three, remove the filter course of PM2.5 only at new wind channel setting, when opening Inner eycle, indoor PM2.5 cannot remove.
In addition, most central air conditioner system also has certain dedusting and filtering function, but, because of central air conditioner system can not be regular cleaning and sterilization, its internal system becomes bacteria breed place, and its environmental pollution brought causes the attention of people day by day.Hermetic type is more and more tended in our living space current, gathering of air in this enclosure space, dust, formaldehyde etc. causes air contaminated, cause City Building syndrome, room conditioning disease, organic contamination etc., it directly affects the health and lives safety of people.
In sum, being badly in need of exploitation one at present can according to the indoor PM2.5 concentration of at-once monitor and CO
2concentration according to indoor PM2.5 concentration and CO
2the indoor air purifier that the automaticity that concentration adjusts recurrent state is in time higher.
