An outdoor air cleaning system includes a partition surrounding a purification space to isolate the purification space from an external space and having at least one opening connecting the purification space to the external space, an air purifying device configured to supply purified air to the purification space, and a controller configured to control the air purifying device. An openness level defined as an area ratio of the opening with respect to a surface area of the partition is about 10% or more and about 50% or less.

The present invention relates to an air purifier in which vertical rotation and horizontal rotation are performed simultaneously and independently and which has a stable structure.

The present disclosure relates to an air conditioner and an augmented reality apparatus for informing an indoor air condition and a control method therefor. The air conditioner informing an indoor air condition may include a sensor configured to sense an air condition, one or more processors controller configured to control an air discharging operation of the air conditioner, estimate an air condition of a space within a predetermined range from the air conditioner based on information on an air discharging operation of the air conditioner and information on the air condition sensed by the sensor. Here, the processor may estimate a space-specific air condition of an indoor space using a depth neural network model that is pretrained and estimate the air condition in consideration of the operation of other air conditioners in the Internet of things environment through the 5G communication environment.

The invention relates to air cleaning and enrichment systems, namely, to systems for providing a user with a healthy air, and it may be used in living, training, medical and working rooms, interiors and cabins of vehicles in order to provide household, medical and other people needs in the air that is cleaned from harmful impurities and chemically healthy.

The system In.AirBox for providing a user with a healthy air is capable of creating the airflow and comprises a room with at least one means for arranging the user, an air delivery duct, a control device, at least one container comprising the air that is collected in a forest area or in mountains, or over a sea or a seaside, or cleaned from harmful impurities, or comprising added healthy impurities, an air output duct that is coupled to the at least one container comprising the air and that is capable of supplying the air from the at least one container into the room. The air delivery duct is configured with a filter and is capable of supplying the air from the environment into the room that is capable of being closed and equipped with at least one measurement device that is capable of measuring the air pressure and/or temperature, and/or moisture, and/or a number of impurities therein, and coupled to the control device, while the control device is capable of regulating the airflow rate supplied from the air output and delivery ducts depending on parameters of the at least one measurement device.

A technical effect lies in increase of the efficiency, providing safety for the user's health, flexibility, simplicity of use, simplification of the structure, cost-cutting of the air cleaning and enrichment process.

Disclosed is a powerless humidification module for an air cleaner which is capable of preventing leakage of water into the air cleaner. A powerless humidification module for an air cleaner which is detachably mounted on an upper portion of a body of the air cleaner and is capable of preventing leakage of water includes a base cover having a first opening opened toward the air cleaner and a second opening opened toward a side surface of the first opening, a cistern part located in the interior of the base cover and located such that a space defined between an inner partition wall and an outer partition wall having predetermined heights such that water supplied to one side thereof is stored surrounds a periphery of the first opening whereby water supplied to one side thereof is stored, and a humidification filter located in the second opening.

Provided herein is an air cleaner (200) that includes: a communication interface (260) that receives information concerning operation contents from a server (100); and a processor (210) that, upon partial or complete termination of communication with the server (100), initializes the information concerning operation contents, or initializes a setting concerning acquisition of the information concerning operation contents.

An imaging system includes a housing to define a housing space, a collection device to collect fine particles in the housing space, a detection device to detect a collection performance of the collection device, and a cleaning device to clean the collection device.

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.
