Description
Technical field
The present invention relates to air re-circulation equipment, particularly be equipped with indoor air purification and the recirculation device of signal automatic control system.
Background technology
Because building surface conducts heat, the reason that low-density hot air rising and high density cold air descend, the indoor temperature difference that all exists between the air of ground and roof parts.On roof, in higher heavy construction, for example: in industrial building or warehouse, this temperature difference can reach 4.5 ℃.Even if the very large temperature difference is also arranged in little civilian house, causes people that sometimes hot and sometimes cold sensation is arranged.In summer, when near temperature flooring is low, still there are a large amount of hot-airs can not carry out convective exchange with the cold air of Near Ground near accumulating in roof and exterior wall.Now, this part is introduced indoor heat by the heat transmission and can not be fully used.In winter, the heat that outdoor air is cold and indoor, also cause indoor air temperature inhomogeneous.
Near Ground is people's zone of action, and this regional temperature is the main influence factor of people's activity comfort level.Generally, the temperature monitoring of most of air-conditioning all installs on ceiling or wall.The temperature detected when the temperature monitoring of air-conditioning is increased to the setup control temperature of air-conditioning system when above, starting of air conditioner work.Yet now surface temperature is still lower than the setup control temperature of air-conditioning.This means the air-conditioning quilt pre-cooling.Therefore, the recirculation of air plays an important role for energy-conservation.
United States Patent (USP) (US2012/0052786A1) has designed a room air recirculating system.Air is inhaled into the inside of equipment by the surrounding of this system, its air flow power is to rotate by fan the pressure differential formed to provide.Air intake is positioned on the surrounding outer wall of equipment, is inhaled into the filtering material interception that airborne particulate matter installed on entrance and is stranded on filtering material in the ideal situation.Air, after purifying, is discharged with certain speed by the equipment top, and process realizes the recirculation of air thus.
In air, multiple pollutant is used as the index of indoor pollution, comprises particulate matter, VOC concentration and bacterial number.These pollutants can be because of irritated, asthma, or even other diseases, comprises cancer and Multi-organ dysfunction.Therefore, multiple technologies and equipment are applied to quality and the health that indoor pollutant removes to guarantee indoor environment.
The existing technology that is applied to particulate matter (dust) comprises filtration, electrostatic precipitation etc.The most perfect technology of development is highly effective air particle filtering (HEPA).According to the standard of USDOE, HEPA filters and can pollute the clearance of realizing 99.97% to the dust granules of diameter 0.3 μ m.HEPA can not only comprise the filtration of PM2.5 and PM10 for particulate pollutant, can also be for the removing of bacterium.But the shortcoming of HEPA is the service life of filter membrane, when dust accumulation, after the filter membrane surface forms cover layer, the strainability of filter membrane descends.
The standard that indoor VOC concentration is formulated by the World Health Organization is controlled.The existing technology that can be used for room air VOC pollution cleanup comprises absorption, catalytic ozonation, ultraviolet light catalyzing oxidation (UV-PCO) and low temperature plasma.The VOC absorption plant is design and the simplest technology of operation, and in absorption process, the air that VOC pollutes is by absorbent, and pollutant is adsorbed and is caught in the active surface of adsorbent.Even shortcoming be the operation a period of time after adsorbent do not have saturated before, absorption efficiency will descend.Now absorbent needs to change, and has so just increased maintenance cost.The catalytic ozonation parts are furnished with ozone generator, but should be noted that and prevent that ozone is to the leakage in environment.
UV-PCO utilizes the ozone of activation to activate the PCO reaction and VOC is catalyzed into to CO
2and H
2o.This process does not need ozone generator, and is easy to control produced oxonium ion by controlling UV intensity.The degradation efficiency of VOC can reach 99% on the perfect equipment of design.Low-temperature plasma degradation is the technology that latest development is got up.By applying the electric field of sufficient intensity, a quasi-neutrality environment that contains neutral particle, ion, free radical, electronics and ultraviolet photon has been set up.Free radical wherein comprises hydroxyl radical free radical (OH) and oxygen radical (O), realizes that VOC is to CO
2and H
2the conversion of catabolite under O and other low temperature.The shortcoming of this technology is that power consumption is large, and manufacture and maintenance cost are high.
Business-like bacterium clearance technique mainly depends on ultraviolet light.This technology be develop the most perfect, the safest, the most cheaply and the most effective technology.Simultaneously, and filtering technique in conjunction with can remove killed bacterial body in air, thereby prevention is because dead bacterial body causes the symptoms such as asthma, allergy.But the risk of this technology is the ultraviolet spectra leakage, and this is disadvantageous to health.
Most of air purifier all is designed to manually control or continued operation, and the shortcoming of these designs is to fix its running time, can not automatically adjust with the indoor pollution situation.The result of continuous operation is the unnecessary long operating time to cause too high power consumption.When air pollution concentration high and purify not in time to have and can cause healthhazard.
