Improving efficiency of trans-critical CO2 using an ejector driven by heat rejected in the gas cooler.
Author(s) : JAKOBSEN A.
Summary
This work presents results from a ph.D. study with the objective to investigate different methods of improving trans-critical CO2 systems, especially for reefer applications by lowering the sea water temperature which is fed to the gas cooler. Focus is put on a new innovative hot water driven ejector system, which is investigated theoretically and experimentally. Experimental results show that the ejector system will increase the COP for CO2 systems at seawater temperatures of 34 °C by around 80% at design conditions.
