Described herein is a method for operating a refrigerated shipping container containing respiring produce, the method including: passing a cooled CO.sub.2-rich air stream from an internal environment within the shipping container through a CO.sub.2 selective membrane of a membrane system to produce a cooled CO.sub.2-lean air stream and a CO.sub.2-rich permeate stream; retaining or returning the cooled CO.sub.2-lean air stream to the internal environment; and exhausting the CO.sub.2-rich permeate stream to an external environment outside of the shipping container; drawing external air or permitting external air to pass into the shipping container through an air vent with a pre-set fixed opening of the shipping container in a volume to at least balance a volume difference between the cooled CO.sub.2-rich air stream and the cooled CO.sub.2-lean air stream; wherein the membrane system is operated according to a pre-set mode, and the pre-set mode is independent of a measured gas concentration or pressure of the internal environment; and the pre-set fixed opening of the vent is selected based on one or more characteristics of the respiring produce and the pre-set mode of the membrane system.

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.

The present invention relates to a ventilating and blanking device for a coal storage Eurosilo. The ventilating and blanking device includes a top blanking pipe, an axial flow fan and a baffle door, the top blanking pipe including a first pipeline and a second pipeline, an air supply pipe is connected to a side wall of the second pipeline, and the baffle door is connected to a driving mechanism; during blanking, the driving mechanism drives the baffle door so as to make the baffle door close the air supply pipe and the axial flow fan is shut off; and during ventilation, the driving mechanism drives the baffle door so as to make the baffle door close the first pipeline, and the axial flow fan is turned on. Compared with the prior art, the present invention has the advantages of ventilation efficiency, good ventilation effect, etc.

The invention relates to an apparatus for heat treatment of motor vehicles or motor vehicle parts, in particular for the purpose of killing pests, comprising art insulated sea freight container for temperature-controlled transport, the apparatus comprising at least one fan and at least one heat exchanger in addition to a cooling assembly which is possibly arranged in the container and is possibly capable of functioning.

A refrigerated storage container is provided and includes a container housing defining an interior, an air conditioner operable to maintain control of temperatures within the interior and a local controller configured to cycle the air conditioner on and off within a time window based on waste heat ingestion from neighboring refrigerated storage containers.

A baffle blank for a baffle assembly and a method for deploying the baffle assembly in a storage container for manipulating air flow in the container is provided. The baffle blank is made of stiff planar sheet material and has fold lines, cut lines and sulcations arranged to form a base, a deflector extending from the base along a hinge line, and an angle selector formed as cut-out in the baffle blank. The baffle blank is operable between a collapsed condition in which the base, deflector and angle selector lie in a substantially planar configuration, into a deployed baffle assembly in which the deflector is secured at a selected angle relative to the base by the angle selector with the angle selector extending between the base and deflector.

A shipping container is provided and includes a structural frame defining an interior, a transport refrigeration unit (TRU) and a control system. The TRU includes an inlet through which air is drawn from a lower region of the interior, a refrigeration unit configured to cool the air drawn from the lower region of the interior through the inlet and an outlet through which air cooled by the refrigeration unit is exhausted toward an upper region of the interior. The control system is configured to control an exhaustion of the air cooled by the refrigeration unit toward the upper region of the interior to maintain a predefined environmental condition within the interior.
