ABSTRACT:
A waste heat recovery apparatus including a Rankine cycle which includes a heater for heating an operation fluid by waste heat from a heat-generating device, an expansion unit for converting energy of expansion of the operation fluid flowing out from the heater into mechanical energy, and a condenser for condensing and liquefying the expanded operation fluid, a temperature detector for detecting the temperature of the operation fluid on the inlet side of the expansion unit, a pressure detector for detecting inlet-side pressure of the expansion unit, a pressure detector for detecting outlet-side pressure of the expansion unit, and a control unit. The control unit controls a command rotational speed of the expansion unit based on superheated degree information at the inlet of the expansion unit obtained from the operation fluid temperature and the inlet-side pressure, and pressure information in which the outlet-side pressure is considered.
