摘要： The present invention relates to an air conditioner including a dust collecting filter assembly for collecting foreign substance from the air sucked in through an inlet. The dust collecting filter assembly includes a high-voltage electrode film, a ground electrode films alternately disposed to face the high-voltage electrode film, a separator film disposed between the high-voltage electrode film and the grounding electrode film so that the high-voltage electrode film and the grounding electrode film are spaced apart by a predetermined interval, and a fastening part to fasten the high-voltage electrode film, the ground electrode film, and the separator film together and integrate them. With this configuration, it is possible to simplify the manufacturing process of the dust collecting filter assembly provided in the air conditioner, minimize the distance between the high-voltage electrode film and the ground electrode film, and improve the dust collection performance by improving a dust collection area by the separator film.

摘要： Methods and apparatus of the present disclosure monitor and change operation of an air filtering system or apparatus dynamically over time. Changes to the air filtering apparatus may be associated with a type of facility and air purity requirements associated with the type of facility. Examples of different types of facilities include an office building, a clean room, and a hospital. Apparatus of the present disclosure may include conventional air filters and may include disinfecting air filter sub-assemblies that use a high voltage to charge particles in the air such that those particles may conglomerate and be captured more easily in an air. Methods consistent with the present disclosure may change an air flow rate or may change the voltage used to charge the air particles as conditions associated with the air of a facility change over time.

摘要： Provided are purification systems and methods of using such systems for purifying various environments, such as indoor air, outdoor air, vehicle emissions, and industrial emissions. A purification system comprises an ionizing purifier having a substrate and an active coating. The active coating comprises a pyroelectric and/or piezoelectric material. During the operation, an incoming stream is directed toward the active coating while controlling the average pressure exerting on the active coating. This contact between the incoming stream and the active coating generates negative ions from components of the incoming stream via change in temperature and pressure/force/vibration, etc. The negative ions then interact with pollutants, transforming them into safe, purified materials of the outgoing stream. Unlike the pollutants in the incoming stream, the purified materials are non-harmful, and/or can be easily removed from the outgoing stream, e.g., by filtering and/or other separation techniques.

摘要： An ionization chamber is provided with a series of parallel plates spaced from each other and with holes passing therethrough. Alternating plates have either a highest high voltage or a lower high voltage provided thereto, such as through a DC transformer coupled to an electric power source. Holes in alternating plates are preferably offset so that airflow through the plates occurs along curving pathways. The plates are sufficiently highly charged to cause carbon dioxide to be ionized and for carbon ions to become trapped within wells defining lowest regions of electric charge within an electric field inside the ionization chamber. Fans control airflow through the ionization chamber. A dehumidifier is provided upstream of the ionization chamber to reduce moisture content within the incoming gas. After the carbon has collected within the wells, harvesting of the carbon ions as carbon nano particle powder can occur within a carbon cache.

摘要： Disclosed is an electrostatic induction-type air filtration dust-collecting apparatus and method, whereby a film-type electrostatic filter having high efficiency and a low pressure loss is used as a primary filter so as to enhance air permeability to reduce the pressure loss and to enhance a dust-removing performance of the filter and the primary filter is utilized as an electrostatic inductor so that the performance of a secondary nonwoven fabric filter charged with static electricity can be enhanced and the enhanced performance can be maintained and thus the efficiency of collecting dust including ultrafine particles in air can be increased.

摘要： An air cleaning system has a field charger comprising a plurality of bars comprising a conductive inner core and a non-conductive overmold, and a plurality of pins attached to the bars and extending out of the non-conductive overmold. The conductive inner core is molded over the plurality of pins, conductively connecting the pins, and the non-conductive overmold is molded over the conductive inner core. A method of manufacturing the field charger includes placing a plurality of metal pins in a mold, placing contact points in the mold, molding a conductive resin over at least a portion of the plurality of pins and contact points, molding an insulating resin over the inner core, plurality of pins, and contact points, wherein at least a portion of the pins and contact points extend from the non-conductive overmold, and mounting an earthplate to the conductive overmold.

摘要： A novel device which can ensure safe and effective elimination of collected pathogens and avoid secondary toxins. The device is suitable for installation into various HVAC and air handling equipment to rid the air of dangerous viral agents. The destruction of pathogens is guaranteed by heating collecting surfaces sufficiently. Complete direct line of sight of the lamp to the filter is not required as is with UV light.
