Abstract: A humidifier includes a housing, a humidifying rotor, and an irradiator. The housing is formed with an air passage through which air passes and a water storage tank configured to store water. The humidifying rotor extends over the air passage and the water storage tank. The humidifying rotor rotates so that a portion of the humidifying rotor having absorbed moisture from the water storage tank moves to the air passage and releases the moisture. The irradiator irradiates part of the humidifying rotor with ultraviolet light.

Abstract: A UV emission device includes an irradiator, a control unit, a determiner, and an exposure amount output unit. The irradiator irradiates a predetermined irradiation area in a predetermined space with ultraviolet rays. The control unit controls the irradiator based on a total exposure amount of a target person to ultraviolet rays. The determiner performs a determination process of determining whether or not the target person is present in the irradiation area. The exposure amount output unit outputs an amount of exposure of the target person to ultraviolet rays based on a determination result of the determiner and operation information on the irradiator. The control unit adds the amount of exposure of ultraviolet rays to the total exposure amount of ultraviolet rays in order to update the total exposure amount.

Abstract: Contamination in a region around a person who can be a contamination source is reduced. An ultraviolet ray radiation apparatus is provided with a light source that emits ultraviolet rays. This light source emits ultraviolet rays in the range of wavelength from 190 nm to 230 nm. In the ultraviolet ray radiation apparatus, the light source emits the ultraviolet rays. This forms an ultraviolet ray region, which is a region for receiving the ultraviolet rays, between a first region R1 and a second region R2 adjacent to the first region R1.

Abstract: An environment detection system includes a sound wave transmitter, a sound wave receiver, and a determination unit. The sound wave transmitter transmits a detection sound wave to a target space where an environment control device that conditions air in a space is installed. The sound wave receiver receives the detection sound wave transmitted by the sound wave transmitter. The determination unit determines a temperature or an air velocity in a first region near the environment control device, based on predetermined acquired information acquired from the environment control device. The environment detection system obtains a temperature or air velocity distribution in the target space, based on measured sound wave data. A temperature or air velocity distribution in a second region is obtained based on at least either the temperature or the air velocity in the first region determined by the determination unit and the measured sound wave data.

Abstract: An environment detection system includes a sound wave transmitter, a sound wave receiver, and a control unit. The sound wave transmitter transmits a detection sound wave to a target space. The sound wave receiver receives the detection sound wave transmitted by the sound wave transmitter. The control unit controls the sound wave transmitter. The environment detection system detects at least either a temperature distribution or an air velocity distribution in the target space. The control unit executes a first control to regulate at least either a volume or a frequency of the detection sound wave transmitted by the sound wave transmitter so that a volume of the detection sound wave received by the sound wave receiver is higher than or equal to a predetermined reference reception volume.
