Claim 10:
11. A transportation container comprising:
a storage volume;
a refrigeration system in communication with the storage volume, the refrigeration system including an airflow fan configured to ingest exterior air, a condenser coil immediately downstream of the airflow fan, and a vent configured to exhaust spent cooling air from the storage volume;
one or more sensors to detect that refrigeration operations are deteriorating within the transportation container and communicating associated deterioration information to a controller; and
the controller configured to control the refrigeration system, the controller including instructions configured to receive associated deterioration information from the one or more sensors, and in accordance with a determination of a buildup of contaminants within the refrigeration system based on the associated deterioration information, the controller responds to remove power from non-fan components of the refrigeration system and reverse a rotational direction of the airflow fan from a first direction to a second direction such that air is drawn over the condenser coil and expelled from the transportation container using the airflow fan, and revert the rotational direction of the airflow fan to the first direction at a conclusion of a cleaning operation.
