A method and device for controlling operation of sensor in air purifier are provided, to solve technical problem that operating life of sensor is shortened when air quality is detected by sensor in real-time manner since sensor needs to operate whether air quality changes or not. The method for controlling operation of sensor in air purifier includes: obtaining current time period; determining operating mode of sensor based on current time period, and controlling, if time period is daytime period, the sensor to operate continuously for first preset operating period and stop operating for first preset power-down period to perform a periodic control for first preset number of cycles per hour; and controlling, if the time period is nighttime period, the sensor to operate continuously for second preset operating period and stopping operating for second preset power-down period to perform periodic control for second preset number of cycles per hour.

A method and apparatus for air purification are provided. The method includes: acquiring an image of a room to be purified and determining a location at which the image is acquired; determining spatial capacity information of the room to be purified according to the image and the location; and performing air purification for the room to be purified using a purification strategy corresponding to the spatial capacity information.

An air decontamination apparatus for a common HVAC system includes a plurality of venturi holes. The plurality of venturi holes are configured to be positioned in the common HVAC system for forcing airflow in the common HVAC system through the plurality of venturi holes. Each of the plurality of venturi holes including an antimicrobial coating. Wherein, the air decontamination apparatus is configured to kill bacteria and viruses in the airflow in the common HVAC system via the antimicrobial coating on each of the plurality of venturi holes.

Methods, systems, and devices provided in accordance with various embodiments are generally related to the field of thermal management systems for buildings (or volumes in general), such as cold storage, food processing, or other buildings that have areas that are kept below freezing. Embodiments generally pertain to the management of temperature and humidity within these spaces. Some embodiments include system for the management of moisture and temperature inside cold spaces. Some embodiments include a heat and mass transfer exchanger, such as a direct constant gas liquid heat and mass transfer exchanger. Examples of such heat and mass transfer exchangers generally include wet scrubbers. Embodiments also generally include a series of ducts, pipes, heat exchangers, dampers, and/or valves that may allow the system to provide useful temperature and relative humidity levels to one or more spaces or volumes.

A humidification and air cleaning apparatus including a water tank; a transparent body forming at least a portion of the water tank; a watering housing disposed in the water tank to spray water stored in the water tank; a nozzle disposed in the watering housing to spray the pumped water; an air wash inlet disposed in the water tank to receive external air into the water tank; and an air wash inlet disposed in the water tank to discharge internal air out of the water tank. During rotation, the sprayed water forms a certain trajectory and collides with an inner side surface of the visual body. Air flowing outside the water tank forms an outer main stream before passing the air wash inlet. Air passing the air wash inlet forms an inner main stream inside the water tank, which passes the trajectory of sprayed water to the discharge port.

A system reduces risk of pathogen exposure within a space that is located within a facility having a plurality of spaces that periodically have one or more people within the space. The system includes one or more occupancy sensors that are configured to provide an indication of when the space is occupied and when the space is not occupied. A sanitizer is configured to sanitize surfaces within the space when activated. A controller is operably coupled with the one or more occupancy sensors and the sanitizer. The controller is configured to determine a designated time to sanitize the space based at least in part upon information received from the one or more occupancy sensors and to automatically instruct the sanitizer to sanitize surfaces within the space at the designated time.
