An air conditioning device is disclosed. The present air conditioning device comprises: a photocatalytic filter including a space through which air can pass and having a transition metal oxide formed in a nanotube form on the surface thereof, the transition metal oxide removing gases included in the air and including at least one of TiO.sub.2, ZnO, NiO, and WO.sub.3; and a light source for emitting light to the photocatalytic filter.

A computer includes a processor and a memory, the memory storing instructions executable by the processor to heat a passenger cabin of a vehicle, suppress a climate control limiter that prevents an air blower of a climate control component from operating when an engine coolant temperature exceeds a temperature threshold, and actuate a motor on an air pump to introduce air external to the vehicle to the passenger cabin.

Air purification devices include an air inlet and outlet, upstream and downstream sections in air flow communication with the air inlet and outlet and a filter removably positioned between the upstream and downstream sections to filter at least pathogens from air being passed through the filter. One or more ultraviolet (UV) illuminating sources may be positioned in at least the upstream section proximate the filter to illuminate at least an upstream surface of the filter with sufficient UV radiation to kill viable pathogens that accumulate on the filter. One or more ozone generating sources may be positioned to generate ozone in sufficient concentrations to kill viable pathogens proximate the device. The UV illuminating sources and ozone generating sources may be positioned to provide a predetermined pressure drop across the sources and air flow pattern proximate the filter, and enable the filter to be removed without handling the sources.

A flexible ion generator device that includes a dielectric layer having a first end, a second end, a first side, a second side, a top side, and a bottom side, at least one trace positioned on the dielectric layer and having a plurality of emitters engaged to the at least one trace. A plurality of lights disposed on the dielectric layer.

An improved poultry production method comprising providing dry hydrogen peroxide (DHP) to poultry eggs, chicks and birds, and devices for providing DHP to poultry production during laying, incubating, hatching, and growing.

An air treatment device includes: a casing having an inlet through which air is drawn, and an outlet out of which the air drawn through the inlet is blown; a blade configured to adjust a direction of the air blown out of the outlet; and a generator configured to generate an antimicrobial element that sanitizes the blade. The blade has a first surface, and a second surface opposite to the first surface. The blade is shiftable between a first position in which the antimicrobial element is provided to the first surface and a second position in which the antimicrobial element is provided to the second surface.

An automated method for implementing UV-C light for air purification in hotel rooms is disclosed. By implementing a method for identifying the hotel room rental status and occupancy status, the UV-C light can be automated to a specific cycle time that will not cause issues with guest complaints or potential safety issues.

A germicide system for use in an air duct including a lamp, a lamp housing, and a control unit. The lamp housing is adapted to be positioned in an interior of the air duct and includes a lamp shield and quartz wool carried by the lamp shield. The lamp is carried by the lamp housing. The control unit is adapted to be positioned entirely in an exterior of the air duct and adapted to provide power to the lamp.

An air sanitization and purification system controlled by a thermostat in wired or wireless communication with an ultraviolet germicidal irradiation light or bipolar ionization appliance, with operation of the light or appliance controlled according to a pre-defined operation schedule of a heating, ventilation and cooling (HVAC) system or by receipt of sensor data indicating the presence of a person with an enclosed area heated or cooled by the HVAC system.

An improved technology for inactivation of viruses, for example the SARS-CoV-2 virus that is causing the Covid-19 pandemic, is described. The technology can include a device that includes a substrate coated in a polymer that is infused with a pathogen inactivating material. In various embodiments, at a given time, a portion of the pathogen inactivating material is exposed to the environment, and the device is configured to periodically or intermittently expose additional pathogen inactivating material to the environment. For example, the polymer can be ablative or sacrificial.
