The design of the ORC engine for the ORC4SHIP project has been completed. The ORC will be installed in the ship's engine room to recover heat from the engine’s cooling system. The 3D drawings show the layout of the 20kWe ORC unit with its main components.
A screw expander Hanbell was selected as the expansion device of the system, while a centrifugal pump Grundfos of vertical flow with magnetic coupling was selected to cover the needed head.
The whole engine was designed for organic fluid R1234ze (E). A shell-tube heat exchanger was designed as the engine’s condenser, while a plate heat exchanger was selected as evaporator.
