Design and Analysis of Charge‐Reduced Refrigerant Cycles Using R290 [PDF]
Chemie Ingenieur Technik, 2023 AbstractR290 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.
