Abstract: A method for controlling an environment in a storehouse includes monitoring a monitoring target with a stored item and the monitoring target stored in the storehouse; and controlling the environment in the storehouse based on a result of monitoring the monitoring target. The monitoring target is disordered due to the environment earlier than the stored items.

Abstract: A determination device includes an irradiator, an extractor, an imager, and a determiner, The irradiator irradiates an object including a food or a plant with a light. The extractor extracts a predetermined fluorescence emission having a predetermined wavelength out of fluorescence emissions generated from a surface of the object irradiated with the light. The imager captures a fluorescence image indicating the predetermined fluorescence emission. The determiner determines a state of the object based on an index indicating a fluorescence intensity of the fluorescence image.

Abstract: A selection apparatus according to an aspect of the disclosure includes a calculation unit configured to calculate, based on data correlated with power consumption of portable cold-energy equipment and data related to a set temperature of the cold-energy equipment, an amount of power consumption expected during transportation of the cold-energy equipment to a predetermined destination; and a selection unit configured to select, based on the amount of power consumption calculated by the calculator, a rechargeable battery to be mounted on the cold-energy equipment.

Abstract: A ripening controldevice includes a holding unit, a desorption unit, and a supply unit. The holding unit holds a ripening component that is generated from an object and ripens the object. The desorption unit desorbs the ripening component held in the holding unit from the holding unit. The supply unit supplies the ripening component desorbed by the desorption unit into the target spaces (S).

Abstract: A quality determination apparatus includes a state detector and a main processing unit. The state detector detects a state index. The state index is an index indicating a state of a target article contained in a storage space where an internal environment is controlled. The main processing unit performs a determination operation. The determination operation is an operation of determining whether a sign condition indicating a sign of degradation of the target article is met based on the state index detected by the state detector.

Abstract: An internal air adjustment device supplies low-oxygen-concentration air to a storage, and maintains the oxygen concentration of internal air in a target oxygen concentration range that is lower than a reference concentration. The internal air adjustment device performs an oxygen-concentration restoration operation. The oxygen-concentration restoration operation is an operation of increasing the oxygen concentration of the internal air to the reference concentration from the target oxygen concentration range. In the oxygen-concentration restoration operation, a controller of the internal air adjustment device regulates the flow rate of external air that is supplied into the interior of the storage.

Abstract: An electric field generating device includes an electrode and a voltage applying device that applies a voltage to the electrode. The electric field generating device is configured to generate an electric field in an indoor space of a container. The electric field generating device is provided with a supporting member that supports the electrode to be movable between a predetermined use position at which an electric field can be generated in the indoor space of the container and a predetermined housing position that differs from the use position, and a fixing member that fixes the electrode immovably at the use position.
