The invention relates to devices for the treatment of air of at least one room. These are distinguished in particular by the fact that air which is low in bacteria, germs and odours can be provided in at least one room.

For this purpose, the device has at least one supply air line which supplies treated air and in each case has at least one air treatment device having at least one ionization module, an air flow sensor and an air humidity sensor. At least one exhaust air line has at least one air quality sensor. Furthermore, at least one dust-measuring device arranged in front of the ionization module and/or at least one dust-measuring device arranged in the exhaust-air line are present. In addition, the ionization module, the sensors and the dust measuring devices are connected to a data processing system for increasing or decreasing the ionization intensity. Furthermore, at least one device measuring the load current of the ionization module is connected to the data processing system, which assigns an operating state of the ionization module in the event of a load current change as a function of the measured values of the dust measuring device.

The present embodiment may comprise: a housing that have a suction port, a space formed therein, and a discharge port formed in an upper portion thereof; a purification unit and a blowing unit accommodated in the space; a discharge guide that is disposed in an upper portion of the housing and discharges blown air to the discharge port; a tilting mechanism that is connected to the discharge guide to tilt the discharge guide; and a lifting and lowering mechanism that lifts and lowers the tilting mechanism.

Aspects of the present disclosure provide a system for abating a hydrocarbon compound (HCC) in air using photocatalytic oxidation (PCO). For example, the system can include an air handling unit (AHU), a sensor and a control panel. The AHU can be configured to abate HCC in air using PCO. The sensor can be configured to sense a level of the HCC in the air. The control panel can be configured to control the AHU based on the level of the HCC.

A method of capturing carbon dioxide (CO.sub.2) present in air is provided. The method includes adding a carbon-dioxide-capturing device to a heating, ventilation, and air conditioning (HVAC) system of a building. The carbon-dioxide-capturing device is added to one or both of an air handler and air-distribution ductwork of the HVAC system. The method further includes circulating air including carbon dioxide through the carbon-dioxide-capturing device in the HVAC system. A direct decarbonization system for capturing carbon dioxide present in air is also provided. The system includes an HVAC unit, air-distribution ductwork connected to the HVAC unit, and a carbon-dioxide-capturing device disposed in one or both of the HVAC unit and the air-distribution ductwork. Carbon dioxide gas present in air passing through the HVAC unit or the air-distribution ductwork is removable from the air by the carbon-dioxide-capturing device.

A dryer stand including a side cover having a through hole through which air is introduced and discharged, a seat provided above the side cover and allowing a dryer to be positioned thereon and an air purifier disposed in an inner space defined by the side cover, wherein the air purifier includes a fan for generating an air flow, and a filter disposed in a flow path of air flowing by the fan to dry a target object.

A system and method for maintaining, monitoring and improving air quality and purity in a room or environment, such as a hospital room or operating room.

Infectious diseases can be transmitted to humans, or between humans and animals, by airborne viruses and bacteria, known as infectious aerosols. Current protective measures that individuals can take to avoid inhaling such aerosols are either marginally effective (personal face masks) or impractical (self-contained breathing apparatuses). Building ventilation systems employing high-efficiency filters to prevent distribution of such aerosols suffer from high energy costs and high filter replacement costs. The development of conventional, intramuscularly administered vaccines takes months or years to produce enough doses to protect a population from a rapidly spreading infectious disease. Airborne viruses and bacteria have been shown to be completely inactivated when exposed to non-thermal plasmas. Results indicate the potential for sub-lethal exposures of airborne pathogens could render them unable to spark an infection in a host, but still retain the necessary surface proteins to cause an immune response in the host.
