Abstract | The invention relates to a method for controlling the temperature of a waste heat recovery system associated with a combustion engine, the waste heat recovery system comprising a working fluid circuit; at least one evaporator; an expander; a condenser and a pump arranged to pump the working fluid through the circuit, wherein the at least one evaporator is arranged for heat exchange between the working fluid and a heat source associated with the combustion engine, wherein the condenser of the waste heat recovery system is connected to a cooling system. The method comprises the steps of: determining if a combustion engine associated with the waste heat recovery system is about to be shut down; and controlling the temperature in the waste heat recovery system based on whether the combustion engine is about to be shut down or not. |
