Abstract: A refrigeration system for an interior space (260), includes an evaporator coil (230) and evaporator fan (242) residing within the interior space, the evaporator coil (230) being configured for refrigerating the interior space (260); an evaporator motor (235) coupled to the evaporator fan (242) along an axial shaft; a condenser coil (215) and fan (210) disposed adjacent to the evaporator motor (235); and an insulation panel (250, 255) that separates the evaporator motor (235) from the evaporator fan (242).

Abstract: A pre-wired auxiliary power circuit (45, 47) is built into a transport refrigeration system for supplying electrical power to an optional auxiliary system when installed in connection with the transport refrigeration unit. A low cost safety interlock (70) is provided in association with the auxiliary power circuit.

Abstract: A method for reducing air leakage from a refrigerated container includes positioning at least one inflatable device about a rear end of the refrigerated container; coupling the at least one inflatable device to one end of an elongated duct located within an interior space of the refrigerated container; coupling a second end of the elongated duct to an outlet port of the evaporator fan; circulating, via the evaporator fan, air through the interior space; and extracting the circulated air through the elongated duct and into the at least one inflatable device.

Abstract: A refrigerated transportation cargo container includes a transportation cargo container and a refrigeration unit located at an end of the transportation cargo container to provide a flow of supply air for the transportation cargo container. The refrigeration unit includes a housing having a front wall with one or more front wall openings therein. A back wall is located opposite the front wall and nearer to an interior of the cargo container relative to the front wall. One or more components of a refrigeration unit are installed in the housing via insertion through the one or more front wall openings.

Abstract: Embodiments of systems, apparatus, and/or methods can control conditions such as temperature within a container of a transport refrigeration system. Embodiments can include a controller for controlling the transport refrigeration system to reduce power consumption. Embodiments of systems, apparatus, and/or methods for operating the same can control cycling of a transport refrigeration unit to conserve power where a subsequent cycle time in a power savings mode is based on at least one previous cycle time. In addition, components can be enabled based on monitored conditions to reduce power consumption.

Abstract: A method of monitoring and controlling temperature of a cargo in a refrigerated transportation cargo container includes measuring a temperature of a plurality of portions of the cargo located in the cargo container via a plurality of temperature sensors directed at the portions of the cargo. One or more of the measured cargo temperatures are compared to a preselected threshold. Operation of a refrigeration unit disposed at the cargo container in operable communication with the plurality of temperature sensors is changed based on a result of the comparison. A transportation cargo container refrigeration system includes a plurality of cargo temperature sensors configured to determine a temperature of at least portions of a cargo. A refrigeration unit and controller are connected to the refrigeration unit and the cargo temperature sensors to control operation of the refrigeration unit based on data received from the cargo temperature sensors.

Abstract: A transportation cargo refrigeration system includes a refrigeration unit to provide a flow of supply air for a refrigerated cargo container. A refrigeration system outlet allows the flow of supply air into the cargo container. A mixing chamber is located between the refrigeration unit and the refrigeration system outlet for mixing of the flow of supply air thereby reducing supply air temperature fluctuation at the refrigeration system outlet. A method of operating a refrigeration system for a refrigerated cargo container includes flowing supply air through a refrigeration unit thereby reducing a temperature of the supply air. The supply air is directed into a mixing chamber and mixed in the mixing chamber until a selected supply air temperature is achieved. The supply air is directed through a refrigeration system outlet and into an interior of a cargo container.

Abstract: An insulation system for a cargo container (105), includes at least one wall (115, 120, 125, 130) having an exterior panel (205) and an interior liner (215), the exterior panel and the interior liner being substantially parallel to each other; a cavity disposed between the exterior panel and the interior liner, the cavity being coextensive with a surface area of each of the exterior panel and the interior liner; at least one vacuum insulation bag (210) disposed within the cavity (220), the at least one vacuum insulation bag (210) being configured for insulating the interior liner from the exterior panel.
