Abstract
An air purifying device is provided with an inlet pipeline and an outlet pipeline, which communicate with an air circulating pipeline of an air-conditioner. An active carbon purifying device communicates between the inlet pipeline and the outlet pipeline. An ozonizer or an ultraviolet sterilizer tandem communicates before the active carbon purifying device, or both the ozonizer and the ultraviolet sterilizer tandem communicate before the active carbon purifying device. Thus the air collected back from the room enters into the ozonizer and the ultraviolet sterilizer. The injurant and the toxicant of germina and virus in the air are killed, and the air enters into the active carbon purifying device or a molecular sieve purifier. Not only the harmful impurity of formaldehyde, ethanol and benzene, which are produced during the indoor fitment course and are emanated from the furniture, are adsorbed, but also the remnants ozone of the former system is decomposed to be clean, and the cadavers of the germ and the virus, which are killed before, can also be adsorbed and be prevented entering into the room to influence the indoor air odor.
Description
Technical field the utility model relates to a kind of central central air-conditioning system that is used for, the air trapping in a plurality of rooms is being carried out cyclic process, to the device that air purifies, the device that further can also form and increase anion, adds the air cleaning of oxygen-enriched air
Background technology is along with social progress and living standard improves constantly, and people also more and more pay attention to the improvement of condition of work and living environment.In the face of building up of increasing high-grade office building and office room, use the user of central air-conditioning also more and more.But along with the increase of fitting up and use all kinds of furniture, office accommodation scale, the phenomenon of room air pollution is also more and more serious.The pernicious gases such as carbon monoxide that ammonia, organic matter, the smoking that evaporates in the formaldehyde that some finishing materials and furniture come out, benzene series thing, the food process is distributed cause certain harm all can for people's health; More especially the germ, the virus that have serious gas communicable disease, in the closed room of central air-conditioning is housed, can be sent to other rooms to unclean air rapidly by gas pipeline, so just cause artificial disease's spread and popular, seriously threaten people's physical and mental health.In order to address this problem, a lot of units all develop and have used the utensil of some air filtrations, purification, sterilizing aspect, the popularization and application of family's air-conditioning and central air-conditioning by ventilation and adjusting indoor temperature, makes IAQ obtain very big improvement.But these methods have certain limitation, and the use face that has is little, can not guarantee that large tracts of land user and most of personnel are benefited; The function singleness that has, each effect link can not be compatible, can not play synergy, more do not have to air not only sterilization kill virus but also the effect of filtration, purification.Simultaneously, the room of air-conditioning is housed, all defective to the oxygen content that human body is highly profitable, the air of purification also needs to increase the content of oxygen in the air.
Summary of the invention
At the problems referred to above, the utility model is exactly the air pollution problems inherent that solves the air-conditioning cyclic process, and a kind of air cleaning unit of central air-conditioning is provided, and further can also provide the air cleaning unit that can increase oxygen enrichment.
Central air-conditioning air cleaning unit of the present utility model (as Fig. 1), it is a kind of central air conditioner system that is used for, the device that the air that central air-conditioning is circulated purifies, the inlet and outlet piping that is communicated with the Air Conditioning circulating line is arranged, it is characterized in that: the active carbon purifying device or the molecular sieve purification device of connection are arranged between the inlet and outlet piping, and before active carbon purifying device or molecular sieve purification device, ganged up ozone generator or uv disinfection device or ganged up ozone generator simultaneously and the uv disinfection device.The air of returning from indoor collection enters ozone generator, uv disinfection device like this, with the strong oxidizing property of ozone, the decomposition of airborne germ virus is killed, and by the ultraviolet lamp air chamber, kills airborne germ virus.The later air of harmful poisonous thing such as kill pathogens virus enter active carbon purifying device or molecular sieve purification device, not only can be giving out absorption such as the objectionable impurities of adopting formaldehyde, alcohol, benzene series thing on interior decoration process and the furniture; Go back simultaneously anterior remaining ozone is decomposed totally at this, can also adsorb corpse and the smell of the bacterial virus that has killed the front, effectively prevent to influence in the inlet chamber room air smell.As adopt the carbon fiber adsorption and catalytic combustion bed to adsorb to be difficult to and kill the remaining able-bodied multiple viruses of serious harm people such as adenovirus III, Respiratory Syncytial Virus(RSV), influenza H1 virus and influenza H3 virus; Containing the medicine active carbon clarifier as employing, just can also be germ, the virus that the front portion is not killed, and continues to kill and absorb by medicine active carbon.For the dust purification that will contain in the air gets off, main is to prevent that too much dust from influencing the sterilization virus killing and too much being adsorbed on active carbon or molecular sieve, so preferably also be communicated with dust filter unit at ozone generator or uv disinfection device leading portion.In order to guarantee the air quality through purifying, active carbon purifying device or molecular sieve purification device back segment also preferably are being communicated with anion generator equally, to increasing anion concentration through the air that purifies; In order to guarantee the air oxygen content through purifying, active carbon purifying device or molecular sieve purification device back segment also preferably are being communicated with oxygen-enriched generator, have just formed with the Air Conditioning circulating line also be communicated with oxygen-enriched generator, supplemental oxygen in cleaned air passes.
The utility model is compared with existing air purifier, because comprehensive sterilization disinfector and adsorption filtration medicine active carbon clarifier or the molecular sieve purification device of adopting, not only play original multiple harmful substances in the absorbed air, corpse and harmful substance or bad smell that sterilization virus killing process produces have also been adsorbed, make and the organic combination of function that purifies air produced higher clean-up effect; Further the dust filter unit that increases not only can the Chalk-dust filtering fiber, has also improved the efficient of follow-up sterilization virus killing and absorption harmful substance; Through purifying disinfection, add oxygen or anion again, make that oxygen concentration remains between 21～22% in the pure air, the anion active component is arranged again simultaneously, people work and live in such atmosphere, it is comfortable to feel relief, and the blood oxygen amount is big, and the brains reaction flexibly, high efficiency, more do not have toadstool harm, truly have the pure and fresh sensation of forest lakeside, help people relaxed and joyful, prolong life.
