Rankine cycle for use in heat recovery system for vehicle e.g. motor vehicle, has two collecting vessels whose volume corresponds to volume of heat exchangers to be emptied, where one of collecting vessels accommodates water

摘要

The cycle (30) has an inlet or injecting opening (40) through which a medium is introduced into the cycle during stoppage, so that the medium replaces water in a sub-area of the cycle. A collecting vessel (31) is provided with increased storage volume, and another collecting vessel accommodates water. Volume of the collecting vessels corresponds to volume of heat exchangers (12, 13, 22, 33) to be emptied. An air supply line and a water vapour line are attached at the injecting opening. A heating device is provided for producing water vapor. An independent claim is also included for a method for operation of a Rankine cycle.
