Abstract: There is disclosed a transport refrigeration unit comprising an enclosed cargo space, an outer refrigeration cycle configured to transfer heat from the cargo space exteriorly of the cargo space, to cool the cargo space; a container installed within the cargo space; and an inner refrigeration cycle configured to transfer heat from an interior of the container, to cool the interior of the container. There is also disclosed a portable refrigeration device for use in such nested cooling arrangements, methods of adapting a transport refrigeration unit and/or portable refrigeration device for such use, a refrigeration module for such use, and an associated method of operating a transport refrigeration unit.

Abstract: A method for power and load management of a transport climate control system using a vehicle electrical system is provided. The method includes a controller determining a power draw of the transport climate control load network, determining an amount of power available from the vehicle electrical system, and determining whether the power draw of the transport climate control load network exceeds the amount of power available from the vehicle electrical system. Also, the method includes shedding one or more loads of the transport climate control load network to reduce the power draw of the transport climate control load network until the power draw of the transport climate control load network matches the power available from the vehicle electrical system. Further, the method includes supplying power from the vehicle electrical system to the transport climate control load network.

Abstract: There is disclosed a climate controlled vehicle 11 comprising: a prime mover 21; a transport climate control unit 14; a vehicle power network 204 comprising: an alternator 205 configured to be driven by the prime mover when the prime mover is active, a primary battery 210 electrically connected to the alternator for charging; a secondary battery 211 electrically connected to the alternator for charging; power supply terminals 207 connecting the vehicle power network to the transport climate control unit; a switch 206 having a closed configuration in which the primary battery and the second battery are electrically coupled to the alternator for charging and an open configuration in which the secondary battery and the power supply terminals are isolated from the primary battery to prevent power supply from the primary battery to the transport climate control unit.
