摘要： A disinfection system for controlling an indoor environment of a building. The disinfection system includes a disinfection device configured to detect pathogens in the indoor environment and performing disinfection procedures on the air and surfaces. The disinfection system further includes a controller configured to receive, from a treated space in the indoor environment, sensor data from the disinfection device or a sensor indicating an amount of a deactivated pathogen. The controller further configured to determine the amount of the deactivated pathogen corresponds to a deactivation ratio or deactivation percentage of active to deactivated pathogens in the treated space. The controller further configured to adjust the one or more disinfection procedures based on the deactivation ratio or the deactivation percentage of the amount of the deactivated pathogen and a pathogen type, wherein adjusting the one or more disinfection procedures comprises adjusting an operational parameter of the disinfection device.

摘要： Methods and systems described perform air cleaning and/or sanitization in a heating, ventilation, air conditioning, and/or refrigeration (HVACR) system by detecting a concentration of airborne contaminants in a space serviced by the HVACR system. The detected concentration of airborne contaminants is determined whether it exceeds a threshold relative to a capacity of a first air cleaner. When the detected concentration of airborne contaminants exceeds the threshold, a second air cleaner is selected and enabled to be activated in the space. When the detected concentration of airborne contaminants does not exceed the threshold, the first air cleaner is selected and enabled to be activated in the space. The first air cleaner has a cleaning material different from the second air cleaner, and the first air cleaner, relative to the second air cleaner, treats the space at a lower concentration of airborne contaminants. The second air cleaner includes specifically designed cleaner modules.

摘要： A conception of locating and completely cleaning indoor air pollution is provided. A plurality of physical or chemical first devices are disposed to determine characteristics, concentrations and locations of air pollution. A fan, a physical second device or a chemical second device is selected and enabled in accordance with the position closest to the location of the air pollution to generate an airflow. Various mathematical operations and artificial intelligence operations are implemented to improve efficiency of locating the air pollution, draining the air pollution and completely cleaning the air pollution. A wired and wireless network is utilized to optimize efficacy of the physical second device or the chemical second device. The mathematical operations are utilized through the wired and wireless network to maximize effects of the physical second device and the chemical second device for completely cleaning the air pollution.

摘要： A system for improving indoor air quality for shared and confined spaces with people. This allows an improvement in surrounding air quality in indoor spaces and interaction situations with (i) groups of people among themselves (inter-person transmission), (ii) between people and the above-mentioned indoor spaces (confined spaces, buildings and/or airborne and/or overland and/or seaborne passenger transportation systems and/or confined patient transportation systems such as pods/incubators and others similar thereto), and also (iii) for interaction between people and invasive and non-invasive mechanical ventilation systems. The system proposes the use of a system based on fluid mechanics and UV wavelengths for inactivating viruses and bacteria.

摘要： A human-activity-environment air-purifying apparatus is provided that draws in airflow from an ambient environment, kills germs in the airflow within the apparatus and expels purified airflow back into the environment. The apparatus has a housing with an interior chamber. An airflow enters the chamber through an inlet. From the interior chamber, the airflow is expelled through an outlet. The apparatus has a germ-killing-system that kills germs in the airflow and has an airflow-generator which causes the airflow to flow from the inlet to the outlet. In one aspect, the apparatus has a three-dimensional filter structure that has air-filter-surfaces that define a filter interior region and encompassed by the air-filter-surfaces of the filter structure. The filter is positioned in connection with the inlet so that airflow entering the inlet is dispersed into the housing interior chamber in multiple directions exclusively through the air-filter-surfaces of the three-dimensional filter structure.

摘要： Embodiments of the present disclosure relate to devices, systems, and methods for treating microorganisms within an enclosure. The enclosure can be operably coupled to an oxidant source such that oxidant discharged by the oxidant source is disposed within an internal volume defined by the enclosure. The oxidant can modify the microorganisms within the internal volume to render the microorganisms harmless or inert. The oxidant source can discharge a first quantity of oxidant over a first duration of time and subsequently discharge a second lesser quantity of oxidant over a second duration of time to limit the concentration of oxidant to which items within the enclosure are exposed. This process can be repeated for a predetermined duration of time until the microorganisms within the enclosure are sufficiently treated and without damaging the enclosure or items disposed within the enclosure.

摘要： A fluid treatment device includes a photocatalytic filter for deodorizing and sterilizing a fluid; a frame for fixing the photocatalytic filter; and a light source unit coupled to the frame. The light source unit includes a light source support member and a light emitting diode, which is provided on the light source support member so as to emit light at the photocatalytic filter. The frame and the light source support member are coupled in a form that separates the photocatalytic filter from the light emitting diode.
