摘要： An inside air control apparatus includes a composition adjuster. Outside air flowing in a first inflow path and inside air flowing in a second inflow path flow into the composition adjuster as the air to be treated. The composition adjuster separates the air to be treated into first air and second air. The first air flows into a first outflow path. The second air flows into a second outflow path. An outlet switching mechanism changes the destinations of the first air and the second air.

摘要： A gas supply device supplies an internal space of a container with nitrogen-enriched air to reduce an oxygen concentration of the internal space. If the oxygen concentration of the internal space gradually falls to reach a reference concentration C2, the gas supply device stops. If outside air enters the internal space at a gap between the container and a container refrigeration apparatus, the oxygen concentration of the internal space rises after the stop of the gas supply device. If the oxygen concentration of the internal space rises to reach an upper limit concentration C3, an internal fan controller switches a rotational speed of an internal fan from “HIGH” to “LOW.” The gas supply device is activated. As a result, the amount of the outside air entering the internal space can be reduced to reliably drop the oxygen concentration of the internal space.

摘要： In an inside air control system, a first pump supplies treatment target air to an adsorption vessel, and a second pump sucks gas from the adsorption vessel. In an adjustment operation of adjusting the composition of air in a storage, the inside air control system alternately performs a first action and a second action. When a stop condition for stopping the adjustment operation is satisfied, a controller performs stop control. In the stop control, the controller controls the second pump to suck the gas from the adsorption vessel to which the first pump supplies the treatment target air when the stop condition is satisfied, and controls the second pump to stop after the second pump has operated for a first time T1.

摘要： An air composition adjusting device includes: an oxygen separator that separates oxygen from external air to be supplied to a target space; a gas supply path including a high concentration gas supply path for oxygen through which the oxygen separator communicates with the target space; and a controller that performs an oxygen concentration raising operation of supplying a high oxygen concentration gas, which has a higher oxygen concentration than external air before being treated by the oxygen separator, to the target space through the high concentration gas supply path for oxygen.

摘要： A CA system includes a gas supply device which performs a gas supply operation of supplying nitrogen-enriched air into a container, and a controller which performs the gas supply operation so that the inside air has a desired composition. The controller performs carbon dioxide priority control in which the controller performs the gas supply operation if an oxygen concentration of the inside air is equal to or higher than a ceiling concentration higher than a target oxygen concentration, stops the gas supply operation if a carbon dioxide concentration of the inside air is lowered to a critical concentration lower than a target carbon dioxide concentration, and restarts the gas supply operation if the carbon dioxide concentration of the inside air has reached a restart concentration higher than the target carbon dioxide concentration through breathing of the plants.

摘要： Disclosed herein is a CA system which allows first and second adsorption columns to alternately perform an adsorption operation and a desorption operation so that nitrogen-enriched air having a higher nitrogen concentration and a lower oxygen concentration than the air is produced and supplied into the container. The CA system executes a second operation mode in which the nitrogen-enriched air produced for a predetermined time since the desorption operation was started is discharged to the outside of the container, and the nitrogen-enriched air produced until the end of the desorption operation since the predetermined time passed is supplied into the container.

摘要： A carbon dioxide sensor (92) measures the carbon dioxide concentration of inside air. An inside air control system (30) controls the carbon dioxide concentration of the inside air based on a measured value obtained by the carbon dioxide sensor (92). If the measured value obtained by the carbon dioxide sensor (92) returns to a predetermined normal range after falling outside the normal range, the controller (110) of the inside air control system (30) performs a determination operation. The determination operation is an operation for supplying outdoor air to the carbon dioxide sensor (92) to determine whether or not the carbon dioxide sensor (92) is normal.

摘要： An internal air adjustment device that includes a first composition adjustment unit and a second composition adjustment unit. The first composition adjustment unit separates supply air from external air, the supply air having a composition that differs from a composition of the external air, and supplies the supply air into a transport container. The second composition adjustment unit separates discharge air from internal air, the discharge air having a composition that differs from a composition of the internal air, and discharges the discharge air to outside of the transport container. The internal air adjustment device is capable of properly controlling the composition of the internal air in the transport container.
