ABSTRACT:
Containers for transportation of bulk cargo susceptible to spoilage, that have a controlled temperature profile. The refrigerated containers include opposed insulated side walls each of which include internal channels for carrying return air from the floor of the container upward into a plenum. Each plenum is closed at one end, and in fluid communication with a refrigeration unit at the other end to supply return air to the refrigeration unit. Refrigerated air is blown from the refrigeration unit into a central air distribution duct that extends longitudinally along the roof of the container. The central duct is supplied with a multiplicity of spaced apart apertures, and is preferably tapered from a widest point in the vicinity of the refrigeration unit. Thus, substantially equal refrigerated airflow can be obtained throughout the refrigerated container. The container may also be divided into zones of different temperatures by interposing a shutter arrangement between channels of each of the side walls and their respective plenum. By controlling return airflow front zones of the container, flow of air from the central duct into those zones is also controlled. Alternatively, or in addition, airflow from the central duct may also be controlled by a shutter arrangement.
