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.

Abstract: In an air conditioning apparatus, it includes a clean room, an air cleaning section, a cooling section and an air mixing section. The air cleaning section cleans air to supply to the clean room as cleaned air. The cooling section includes a plurality of cooling units and a plurality of non-cooling units. A plurality of cooling units cool air from the clean room to send out as cooled air. A plurality of non-cooling units sends out as non-cooled air from the clean room without cooling air. Each of the quantity of the cooled air and the non-cooled air is determined to compensate an amount of heat generated in the air conditioning apparatus and to reduce a pressure loss given to the air passing through the cooling section to a substantial minimum. The air mixing section mixes the cooled air and the non-cooled air to supply to the air cleaning section. The cleaned air is circulated through the clean room, the cooling section and the air mixing section to the air cleaning section.

Abstract: An airflow distribution arrangement in a side-by-side refrigerator includes a cover which is located in the freezer compartment and which has an inner surface against which cool evaporator airflow is directed. A portion of the airflow travels down the inner surface of the cover to emerge through openings in the bottom of the cover into the freezer compartment. Additionally, the inner surface of the cover forms a part of a lateral duct in communication with the fresh food compartment. In order to force a sufficient quantity of cool evaporator airflow through the lateral duct into the fresh food compartment, a horizontally-extending, inward bulge is formed in the cover and located generally between the region on the inner surface of the cover against which airflow is directed and the bottom of the cover. The inward bulge serves to interrupt the otherwise smooth downward flow of air to produce an air eddy which in turn produces back pressure.
