  • Publication number: 20210033295
    Abstract: 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.

  • Patent number: 10499660
    Abstract: 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.

  • Patent number: 10345014
    Abstract: 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.

  • Patent number: 10295243
    Abstract: 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.

  • Patent number: 10168092
    Abstract: Disclosed herein is a container refrigeration apparatus (10) for cooling air in a container (11). The container refrigeration apparatus (10) includes: a gas supply device (30) which produces nitrogen-enriched air having a higher nitrogen concentration than outside air and supplies the nitrogen-enriched air into the container (11) via a supply passage (44); an oxygen concentration sensor (51) which measures an oxygen concentration of the air in the container (11); and a controller which controls the operation of the gas supply device (30) so that the oxygen concentration measured by the oxygen concentration sensor (51) reaches a target concentration. The container refrigeration apparatus (10) is provided with a measurement passage (88) which guides part of the nitrogen-enriched air passing through the supply passage (44) to the oxygen concentration sensor (51), and an on-off valve (82) is provided for the measurement passage (88).

  • Patent number: 10034484
    Abstract: An oxygen concentration in the interior of a container is detected by an oxygen concentration detection sensor. If the oxygen concentration detected by the oxygen concentration detection sensor is higher than that of a gas mixture, the container is supplied with the gas mixture having an oxygen concentration lower than that of the outside air and higher than a target concentration. The oxygen concentration in the interior of the container is reduced to the vicinity of the oxygen concentration of the gas mixture by supplying the interior of the container with the gas mixture, and then is further reduced to the target concentration by respiration of plants. This appropriately controls the oxygen concentration in the interior of the container, and reduces a decrease in the degree of freshness of the plants.

  • Patent number: 9907316
    Abstract: Disclosed is a gas supply device provided for a container in which a breathing plant is housed. The device supplies nitrogen-enriched air into the container. The device is provided with a malfunction diagnosis section which checks whether each of components of the device works properly or not and specifies a malfunctioning portion if an oxygen concentration of the nitrogen-enriched air does not fall to or below a predetermined concentration. The malfunction diagnosis section checks whether each of an air pump, a motor, and a switching mechanism works properly or not, and determines that an adsorbent is not working properly when it is determined that all of the air pump, the motor, and the switching mechanism are working properly.
