A method for operating a waste heat recovering the rear of the system of an internal combustion engine and the rear, such a waste heat recovery system

摘要

The invention relates to a method for operating a waste heat recovering the rear of the system of an internal combustion engine 5, wherein the waste heat recovery system the rear, a work fluid circuit of the barrel 1 with at least two heat exchangers 2a, 2b, an expansion machine 11, a capacitor 12, a fluid pump 15 and at least one distributor valve 16 to the division of the work fluid circuit of the barrel 1 in two fluid branches 20a, 20b on the input side of the heat exchanger 2a, 2b, and by means of the distributor valve 16 volume flows of the working fluid in the fluid branches 20a, 20b are adjustable. According to the invention, a method for operating a waste heat recovery system and the rear of the rear of a corresponding waste heat recovery system is provided, which in the case of a simple construction that operates in a reliable manner. This is achieved in that, an adjustment of the volume flows in a function of a differential pressure between the fluid branches 20a, 20b is.
