Exhaust heat recovery system

Abstract

The exhaust heat recovery system (1) comprises: an evaporator (2); an expander (3); a condenser (5); a circulation pump (7); a circulation flow path (6) for circulating a working medium therethrough; cooling medium piping (8) which is connected to the circulation flow path (6) and causes a portion of the working medium sent out from the circulation pump (7) to be diverted to flow into the condenser (5); a cooling-side opening/closing valve (13) for switching between a state in which the working medium can flow into the cooling medium piping (8) and a state in which the working medium cannot flow thereinto; and a control unit (10) for performing the switching control of the cooling-side opening/closing valve (13). When a condition under which the temperature of the working medium flowing into the condenser (5) becomes higher than or equal to a predetermined temperature is satisfied, the control unit (10) controls the cooling-side opening/closing valve (13) to switch to the state in which the working medium can flow into the cooling medium piping (8).
