Abstract
A failure determiner is provided to perform a failure diagnosis to successively evaluate functions of the refrigerant circuit and components forming the refrigerant circuit for a plurality of evaluation items. If the failure diagnosis is interrupted, the failure determiner has a restarting function to restart the failure diagnosis from an intermediate point of the failure diagnosis.
Claims20
A container refrigeration apparatus including a refrigerant circuit, the apparatus comprising:
- a non-volatile memory;
- and
- a failure determining processor configured to
- perform a failure diagnosis to successively evaluate in a predetermined sequence a plurality of evaluation items, the plurality of evaluation items including a first type which evaluates functioning of individual components of the container refrigeration apparatus and a second type which evaluates functioning of a combination of the individual components, and
- store, in said non-volatile memory, data associated with progress of the failure diagnosis, wherein
- the first type of evaluation items are evaluated prior to the second type of evaluation items, and
- if the failure diagnosis is interrupted due to a loss of power from a power supply of the container refrigeration apparatus, the failure determining processor is configured to restart the failure diagnosis from an intermediate point of the failure diagnosis based on the stored progress data.
