The use of natural refrigerants in heat pumps and chillers is becoming more and more urgent. Fraunhofer ISE is working intensively on the use of the natural refrigerant propane/R290, which is thermodynamically suitable for many applications, but is subject to restrictions due to its flammability. Therefore Fraunhofer ISE is working with partners on refrigerant-reduced refrigeration circuits and has published pioneering design criteria in this article.
