[EN] R290 is one of the most promising refrigerants for heat pumps and cooling processes working in a temperature range of -15 to 70°C. The nearly neglectable global warming potential and attractive thermodynamic properties allow the design of climate-friendly and efficient refrigeration systems and heat pumps. However, R290 is flammable, and the use of charge-reduced components and designs should be the first central step to reduce safety risks. Whereas the prediction of heat capacity, temperatures and pressure drops are sufficiently precise the prediction of refrigerant charge is not very accurate when using computer-aided design tools. The article presents a method to enhance accuracy for refrigerant cycles with less than 500g of R290.

The work presented in this paper received funding from the German Federal Ministry of Economic Affairs and Climate Action (BMWK) under the grant agreement numbers FKZ 03EN4001A (LC150). Open access funding enabled and organized by Projekt DEAL. The cooperation between Fraunhofer ISE and UPV and the ideas for this work were inspired, supported and supervised by Prof. Jose Miguel Corberan Salvador. He served as Professor in the Department of Applied Thermodynamics and Director of the Institute for Energy Engineering at the Polytechnic University of Valencia (UPV), Spain and died on July 7, 2022 at the age of 65. We will continue the work with his attitude towards professionalism in refrigeration, cooperation and humanity.
