A waste heat recovery system having a working fluid circuit and method of operating such a waste heat recovery system

摘要

The invention relates to a waste heat recovery system comprising a working fluid circuit 1 carrying a working fluid, comprising a heat exchanger 2 switched on in an exhaust line 3 of an internal combustion engine 5, which is part of the working fluid circuit 1 with at least one expansion engine 11, a condenser 12 and at least one fluid pump 15. The invention is based on the object to provide a waste heat recovery system, which is improved over known systems. This is achieved by the fact that the waste heat recovery system has a device 27 for preventing damage to the expansion machine 11 caused by liquid portions of the working fluid. The device 11 is for example a container 21, a calming container 28, 28a, a line section 36 or a filter 26 or the device 11 has at least one such component.
