Abstract
A refrigerated cargo container includes multiple exterior walls defining an exterior volume. Each of the exterior walls is thermally insulating. The container also includes multiple interior walls that define an interior volume within exterior walls. Each of the interior walls is thermally conductive. At least one fluid circuit is disposed between the plurality of exterior walls and the plurality of interior walls. The at least one fluid circuit including an inlet and an outlet and are configured to contain a super cooled fluid.
Claims21
A refrigerated cargo container comprising:
- a plurality of exterior walls defining an exterior volume, each of the exterior walls being thermally insulating;
- a plurality of interior walls define an interior volume within the plurality of exterior walls, each of the interior walls being thermally conductive;
- at least one fluid circuit disposed between the plurality of exterior walls and the plurality of interior walls, the at least one fluid circuit including an inlet and an outlet and being configured to contain a super cooled fluid;
- and
- a controller configured to determine that a sufficient magnitude of super cooled fluid has been inserted into the fluid circuit that a spent fluid has been flushed out of the fluid circuit.
A method for recharging a passively refrigerated cargo container comprising:
- connecting a recharge system to a cargo container;
- flushing a spent fluid from a fluid circuit within the cargo container;
- injecting a super cooled fluid into the fluid circuit within the cargo container;
- and
- disconnecting the recharge system from the cargo container.
