Abstract: A transportation container includes a storage volume. A refrigeration system is contained within the storage volume. The refrigeration system includes a fan configured to ingest exterior air, a condenser coil immediately downstream of the fan, and a vent configured exhaust spent cooling air from the storage volume. A controller is configured to control the refrigeration system. the controller includes instructions configured to cause the refrigeration system to detect an indication of operational deterioration of a transportation container refrigeration system, reverse a rotational direction of an airflow fan such that air is drawn over a refrigeration coil and expelled from the transportation container using the airflow fan, and revert the rotational direction of the airflow fan at a conclusion of a cleaning operation.

Abstract: A refrigerated container (10) that includes a container (10), an auxiliary lock (42), and a ventilation system. The container (10) defines an interior space (14) and has a door (30) to selectively permit access to the interior space (14). The auxiliary lock (42) is arranged to selectively inhibit the door (30) from moving from the closed position towards the open position. The ventilation system includes a leak sensor (44) and a controller (48). The leak sensor (44) is arranged to provide a signal indicative of a concentration of a refrigerant within the interior space (14) of the container (10). The controller (48) is arranged to receive the signal and is programmed to command the auxiliary lock (42) to move towards the lock position, responsive to the signal being indicative of the concentration of the refrigerant within the interior space (14) being greater than a threshold.

Abstract: A ventilation system includes a leak sensor (52), a controller (56), and at least one of an injection port (70) and a vent door. The leak sensor (52) is disposed within an interior space of a refrigerated container (10) and is arranged to provide a signal indicative of a concentration of a refrigerant (18) within the interior space. The controller (56) is arranged to receive the signal. At least one of the injection port (70) and the vent door is disposed on at least one of a floor (30), a front wall (32), and a side wall (38) of the refrigerated container (10).
