Zusammenfassung:	An abnormality determination device for a transporting refrigeration apparatus includes a determination unit that determines an abnormality of the transporting refrigeration apparatus installed on a container. In pre-trip inspection that is conducted before the container is loaded on a transporting device, a test operation is performed for test operating modes. The pre-trip inspection is conducted multiple times. The abnormality determination device is configured to obtain at least part of time series test data related to a same one of the test operating modes in the pre-trip inspection. The determination unit is configured to determine whether the transporting refrigeration apparatus has an abnormality based on a change trend of the time series test data related to a same one of the test operating modes when the pre-trip inspection is conducted multiple times, and when there is no abnormality, estimate an abnormality occurrence time.
