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 from 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.

[ The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follow:] [1.] A refrigerated container for preserving spoilable products having an enclosed interior cargo space, said refrigerated container comprising:(a) a pair of opposing side walls, each side wall comprising at least one channel, the at least one channel having a first end and a second end, the first end of the at least one channel in fluid communication with the interior of the refrigerated container;(b) a plenum adjacent to said side wall, the plenum in fluid communication with the at least one channel through the first end of said channel;(c) a refrigeration unit proximate an end of the container, the unit in fluid communication with the plenum;(d) a duct extending along a length of the container, the unit in fluid communication with, the refrigeration unit for conveying refrigerated air from the refrigeration unit along a length of the duct, the duct having spaced apertures therein for flow of refrigerated air from the duct into the interior cargo space of the refrigerated containerwhereby, during operation of the refrigeration unit, air flows from the interior cargo space of the container through channels in the side walls to the plenum, from the plenum through the refrigeration unit for cooling, and thence back into the interior cargo space via the duct.
