Improving efficiency of transcritical CO2 refrigeration systems for reefers.
Author(s) : JAKOBSEN A.
Summary
The paper presents preliminary results from a study with the objective to investigate methods of improving transcritical CO2 systems. Expanders, sub-cooling units and two-stage systems are investigated theoretically. A new innovative ejector system is investigated experimentally. Theoretical results show that COP for CO2 refrigeration systems can be improved by 30% compared to a R22-brine system, and swept volume reduced by 87%. Preliminary experimental results show that the ejector system is working.
