Abstract: A collection apparatus collects a collection target in air in a target space. The collection apparatus includes an air passage having an inlet and an outlet, a carrier disposed in the air passage, and a plurality of collectors disposed in the air passage. The carrier carries the air. The plurality of carriers collects the collection target in the air carried by the carrier. The plurality of collectors collects different types of collection targets.

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: 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.

Abstract: A correcting system includes an acquisition unit, a storage unit, and a correction unit. The acquisition unit acquires information indicating first capture efficiency of a filter for first microscopic particles. The storage unit stores correction data to correct the first capture efficiency to second capture efficiency of the filter for second microscopic particles. The correction unit corrects the first capture efficiency acquired by the acquisition unit to the second capture efficiency based on the correction data.
