In an air composition adjustment device configured to adjust composition of air in a target space, an air circuit configured to supply air having adjusted composition to the target space is provided with a first passage through which outside air is introduced into an adjuster, and a second passage which is branched from the first passage and through which outside air is introduced into the sensor, and the second passage is provided with a moisture removal portion configured to remove moisture in air introduced into the sensor. This reduces a risk of a failure of the sensor due to contact of the sensor with moisture passed through the passage introducing outside air into the sensor.

A guide member extends from an opening of a casing toward an internal space. The guide member guides the temperature sensor to the internal space. The detector and the lead wire of the temperature sensor are held by the guide member.

Refrigeration apparatus for shipping, and shipping container

An air composition adjustment device is provided with a cover unit including a cover that covers around a gas sensor, an inflow path that takes air into the cover, and an outflow path that causes air to flow out from the cover.

Air composition adjustment device, refrigeration apparatus, and transportation container

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 T

Inside air control system, refrigeration apparatus, and transport container

Left and right edge portions of an external casing of a container refrigeration apparatus each include a column member that is continuous from the upper end to the lower end of a casing. Left and right edge portions of an internal casing each include a side plate that is continuous from the upper end to the lower end of the casing. The column members of the external casing and the associated side plates of the internal casing are fixed together, thereby increasing the strength of the casing including the external casing and the internal casing.

Container refrigeration apparatus

A space which is present between an air intake surface () provided with an air intake port and an air filter () is regarded as a primary space (P) through which air flows into the air filter (), and a plurality of spaces, each of which is present between one of other surfaces of the air filter () and a filter box (), are regarded as secondary spaces (Q) into each of which the air flows out from the air filter (), so that the air is taken out from side surfaces and an upper surface of a filter unit (). This configuration reduces the increase in size of the filter unit () of a gas supply device () even if a dust holding capacity of the filter is made larger than before.

Filter unit, gas supply device, inside air conditioner, and cooling device for container

A container refrigeration apparatus includes a refrigeration cycle unit having a refrigerant circuit, and a controller configured to control an action of the refrigeration cycle unit to adjust a temperature of inside air in a container to a desired temperature. The controller is configured to include an impact determination section configured to determine whether or not a strong impact acted on the container, and an abnormality diagnosis section configured to perform an abnormality diagnosis to diagnose whether or not at least one of the container or the container refrigeration apparatus has an abnormality when the impact determination section determines that a strong impact acted on the container.

In a gas supply device that supplies gas to a target space through a filter unit, the filter unit is composed of a filter box and an air filter housed in the filter box, and the air filter is a filter having a filter substrate made of a membrane filter and a fibrous coating layer covering a surface of the filter substrate through which air is sucked.

Gas supply device, device for controlling inside air, and refrigeration device for container

To facilitate replacement or repair of a sensor for refrigerant leakage detection used for a refrigerator for a storage box such as a container in case of breakdown, a sensor for refrigerant leakage detection is disposed outside of an internal space of a storage box, and an internal air guide passage is provided which guides internal air from a discharge side of a fan provided in the internal space of the storage box to the sensor for refrigerant leakage detection.

Refrigerator

A gas supply device is provided with a heating unit that heats gas flowing into a filter provided in a filter unit.

Gas supply device, interior air adjustment device, and container refrigeration device

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 C, 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 C, 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.

Container refrigeration apparatus with nitrogen-enriched air supply and fan control

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

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.

A refrigeration apparatus controller calculates a refrigeration load of a refrigeration apparatus, and a load signal (S) containing load information indicating a magnitude of the refrigeration load is output from a communication device to an engine controller. The engine controller controls a speed of rotation of a generator engine based on the load signal (S).

Container refrigeration system

A refrigeration system for trailer includes an engine, a generator driven by the engine to generate electric power, an inverter substrate, a temperature sensor that senses a temperature of the inverter circuit, and a heat carrying mechanism that heats the inverter substrate with waste heat of the engine when a sensed temperature by the temperature sensor is an operational temperature or lower.
