    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: 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 control system includes a storage unit, an acquisition unit, a determination unit, a control unit, and a blowing unit. The storage unit stores a second reference capture efficiency obtained by correcting a first reference capture efficiency for first microscopic particles to a reference capture efficiency for second microscopic particles. The acquisition unit is configured to acquire a capture efficiency of a filter for the second microscopic particles. The determination unit is configured to perform a determination process of determining whether the capture efficiency acquired by the acquisition unit is smaller than the second reference capture efficiency. The control unit is configured to control operation of the blowing unit based on a result of the determination process. The first microscopic particles are used to measure a capture efficiency of the filter in a reference standard, and the second microscopic particles are present around the filter installed in an actual environment.

    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: An environment condition measurement device includes a transmitter that transmits a sound wave to a target space, a receiver that receives the sound wave transmitted by the transmitter, and a controller that obtains an environmental condition of the target space based on a propagation time from when the transmitter transmits the sound wave to when the receiver receives the sound wave. The receiver is a directional receiver with a directivity with respect to a sound wave incident at a predetermined incident angle.
