Abstract
A waste heat recovery apparatus includes an evaporator, an expander, a condenser, a liquid-phase refrigerant supply device, and a control device. The control device is configured to control the liquid-phase refrigerant supply device so as to bring the supply of the liquid-phase refrigerant by the liquid-phase refrigerant supply device into a stopped state at least until an amount of the liquid-phase refrigerant stored in the evaporator becomes equal to or lower than a predetermined low refrigerant amount, during operation of the internal combustion engine.
