Malfunction Diagnosis System
Abstract: A malfunction diagnosis system for diagnosing a state of an air conditioner equipped with a refrigerant circuit in which a refrigerant circulates. The malfunction diagnosis system has an abnormality diagnosis unit that uses state data and control data during normal operation of the air conditioner to carry out a normal operation abnormality diagnosis for determining whether an air conditioner abnormality exists. When it is determined that an air conditioner abnormality exists the abnormality diagnosis unit changes a control value for an actuator of the air conditioner and acquires the state data and the control data. The abnormality diagnosis unit then uses the state data and control data prior to the change in the control value and the state data and control data after the change in the control value to carry out an abnormality cause identification diagnosis for identifying a cause of the air conditioner abnormality.
