TLDR
In this article, a Rankine cycle device is used for waste heat recovery in an internal combustion engine, where working fluid circulates through a pump, a boiler, an expander and then through a heat exchanging device, heat exchange occurs in the boiler between the working fluid and intake fluid.Abstract:
The waste heat recovery system includes a Rankine cycle device in which working fluid circulates through a pump, a boiler, an expander and then through a heat exchanging device, heat exchange occurs in the boiler between the working fluid and intake fluid that is introduced into an internal combustion engine while being cooled. The heat exchanging device includes a condenser condensing the working fluid, a receiver connected downstream of the condenser and storing liquid-phase working fluid, a subcooler connected downstream of the receiver and subcooling the liquid-phase working fluid, and a selector device serving to change the ratio of the condenser to the subcooler. The waste heat recovery system further includes a determination device for determining required cooling load for the intake fluid, and a controller for controlling the selector device depending on the required cooling load determined by the determination device.read more
