Abstract: An arrangement and a method for controlling a shutdown phase of a WHR-system. The WHR system includes a main circuit (4) which includes a pump (3), an evaporator (5), an expander (7) and a condenser (10), and a compensation tank (12) which is configured to compensate for volume changes of a working fluid in the main circuit (4) during operation of the WHR system. The arrangement includes a control unit (26) configured to receive information when the shutdown phase of the WHR system is to be initiated and a flow device able to supply working fluid from the compensation tank (12) to the main circuit (4). The control unit (26) is configured to activate the flow device such that working fluid is supplied from the compensation tank (12) to the main circuit (4) when it receives information indication that the shutdown phase of the WHR system is to be initiated.

Abstract: A cooling arrangement for a WHR-system in a vehicle, includes a first cooling circuit including a first radiator (9) in which a circulating coolant is cooled, and a second cooling circuit including a second radiator (14) in which a coolant is cooled to a lower temperature than the coolant in the first radiator (9). A condenser inlet line (17, 38) directs coolant from one of the cooling circuits to a condenser (19) of the WHR-system, and a cooling adjusting device (13, 16, 24, 38) for adjusting the temperature of the coolant in the inlet line (17, 38) to the condenser (19) by the coolant in the other cooling circuit. An arrangement (37, 24) receives information about the cooling to estimates cooling for the working medium in the condenser (19) controls the adjusting arrangement (13, 16, 24, 38) such that the coolant in the condenser inlet line (17) provides the estimated suitable cooling of the working medium in the condenser (19).
