This disclosure provides a method for producing a hydrofluoroolefin (HFO) or fluoroolefin (FO), which is a target compound, with high selectivity, without requiring a high temperature and a catalyst in a synthesis process of the target compound. Specifically, the present disclosure provides a method for producing a hydrofluoroolefin or fluoroolefin having two, three, or four carbon atoms, comprising irradiating at least one starting material compound selected from the group consisting of hydrofluorocarbons having one or two carbon atoms and hydrofluoroolefin As having two or three carbon atoms with ionizing radiation and/or an ultraviolet ray having a wavelength of 300 nm or less, with the proviso that when the at least one starting material compound is the hydrofluoroolefin A, the resulting hydrofluoroolefin is different from the hydrofluoroolefin A.

Manufacturing method for hydrofluoroolefin or fluoroolefin

A gas detector detects difluoromethane present in a remote target space. The gas detector includes a detection portion that detects the difluoromethane by using absorption of light of a predetermined wavelength. The predetermined wavelength is in a wavelength range of any of a first wavelength range of 1659 to 1673 nm, a second wavelength range of 1724 to 1726 nm, a third wavelength range of 2218 to 2221 nm, a fourth wavelength range of 2463 to 2466 nm, a fifth wavelength range of 3316 to 3318 nm, and a sixth wavelength range of 9034 to 9130 nm.

An environmental condition storage device is usable to store an environmental condition. The environmental condition storage device includes an environmental condition acquisition unit, a tactile information acquisition unit, and a storage unite. The environmental condition acquisition unit acquires an environmental condition including at least one of a temperature, humidity, wind, a picture, an image, and a sound. The tactile information acquisition unit acquires tactile information indicating a tactile sensation. The storage unit stores the environmental condition and the tactile information in association with each other.

A cluster classification device includes an environmental condition acquisition unit, a classification unit, and a storage unit. The environmental condition acquisition unit acquires an environmental condition in order to generate a specific environment in a target space. The classification unit generates a cluster from a plurality of environmental conditions acquired by the environmental condition acquisition unit, based on features of the environmental conditions. The storage unit stores the cluster and a feature of the cluster in association with each other. An environment generation device generates, using an environmental condition classified by the cluster classification device, a predetermined environment in the target space. An environment generation system includes the cluster classification device and a control device that controls an environment generation device that generates a specific environment in the target space.
