Abstract
An exhaust-heat recovery apparatus includes: a circulation passage, through which a heat carrier circulates, that has a heat recovery unit evaporating the heat carrier and a condenser condensing the evaporated heat carrier; a heat carrier controller that supplies the heat carrier in a liquid phase to the circulation passage; and a determination unit, in which the heat carrier controller supplies or recovers the heat carrier when a changing rate of an internal pressure in the circulation passage or a changing rate of a temperature of the heat carrier in the circulation passage is within a predetermined range, determines a type of abnormality based on the changing rate of the internal pressure in the circulation passage or the changing rate of the temperature of the heat carrier in the circulation passage after the supplying or the recovering of the heat carrier.
