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.

Quality determination device

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.

Internal air adjustment device

An internal air adjustment device () includes an internal-side passage () and an internal-side treatment unit (). The internal-side separator () in the internal-side passage () separates return air from internal air. The composition of the return air differs from the composition of the internal air. The internal-side passage () supplies the return air into a storage (). The internal-side treatment unit () decomposes ethylene in air that flows in the internal-side passage (). Therefore, the concentration of ethylene of the return air is lower than the concentration of ethylene of the internal air.

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.

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.

Air composition adjusting device

A humidifier cools air in an air path that supplies the air to an internal space of a storage chamber such as a container or a warehouse, extracts water in a water extracting unit, stores the extracted water in a humidifying unit, and humidifies the internal space. The air path includes a main path that communicates with the internal space and a discharge path that discharges a part or all of water-extraction air to the outside of the target space, so that the humidifier can sufficiently humidify the internal space without receiving supply of water.

Humidifier and air composition adjustment device

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.

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

An internal air adjustment device that includes a gas composition adjustment unit including a gas separation film and that adjusts a composition of internal air existing inside a storage box, such as a container, includes a pressure regulating valve that regulates a pressure of air that is supplied from an air pump to the gas separation film of the gas composition adjustment unit.

A method of transferring a slurry is provided. The method involves transferring a slurry containing particles and a liquid using a transfer pump equipped with a ball type check valve. The transfer pump is operated under the condition satisfying the following formula: 7.8&#xd7;10&#x3c;P&#x2264;5.0&#xd7;10. In the formula, P=W(&#x3c1;/(&#x3c1;&#x2212;&#x3c1;))/(C&#xb7;d(d+R)R). W represents the particle flow rate (kg/hr) in the slurry passing through the ball type check valve, C represents the particle concentration (kg/m3) in the slurry, d represents the maximum particle diameter (m) of the particles in the slurry, R represents the ball diameter (m) of the check valve, &#x3c1;represents the density (kg/m3) of the liquid, and &#x3c1;represents the density (kg/m) of the ball of the check valve.

A container refrigeration apparatus includes a CA system which controls the composition of the air in the container. The CA system includes a gas supply device which supplies nitrogen-enriched air, an intake duct which guides outside air to a first space on a suction side of an interior fan, and an exhaust duct which guides air in a second space on the blowout side of the interior fan out of a container. The exhaust duct has an inlet at a location where the flow of the air blown from the interior fan is blocked by a fan housing.

Refrigeration device for container

Disclosed herein a technique for producing a gas mixture for controlling an oxygen concentration in the interior of a container while reducing the overall weight of the apparatus. For this purpose, a gas mixture supply device is provided for a container refrigeration apparatus. The gas mixture supply device is provided with adsorption columns. If one of the first and second adsorption columns is supplied with air, the adsorption columns are pressurized, and nitrogen in the air is adsorbed onto an adsorbent. If air is sucked from the other of the first and second adsorption columns, the adsorption columns are depressurized, and nitrogen adsorbed onto the adsorbent is desorbed. A gas mixture including the nitrogen desorbed from the adsorbent is supplied to the interior of a container.

Refrigeration unit for container

A gas supply device is configured such that its supply state is switchable between a first supply state supplying, as supply air, nitrogen-enriched air produced from outside air into a containe, and a second supply state in which the gas supply device takes outside air therein and supplies, as supply air, the outside air into the container. A CA system is provided with a branch pipe which guides at least part of the supply air flowing through a supply passage to an oxygen sensor, and an open/close valve which opens/closes the branch pipe. An outside air calibration operation is performed in which the open/close valve is opened in the second supply state to guide the least part of the outside air flowing through the supply passage to the oxygen sensor, thereby calibrating the oxygen sensor using the outside air.
