Abstract

The present invention relates to an arrangement and a method for controlling a WHR system arranged in a vehicle powered by a combustion engine (2), The WHR system (17) comprises an evaporator (19) in which a working fluid is heated and evaporated by exhaust gases from the combustion engine (2) and an expander (20) mechanically connected to a power train (22) of the vehicle (1). The vehicle (1) comprises a system (4, 28, 32) with a circulating medium which is heated during at least some operating conditions of the vehicle (1). The arrangement comprises a control unit (12) configured to determine when the exhaust gases are unable to evaporate the working fluid in the evaporator (19), to determine if said medium has a higher temperature than the working fluid, and if these two conditions are met to direct medium from the system to a heat exchanger (27, 30, 37) in which the medium heats the working fluid in the WHR system when the exhaust gases are unable to evaporate the working fluid in the evaporator (19).
