Abstract [en]

Lower global warming potential (GWP) refrigerants must be used in refrigeration education to integrate the environmentallyresponsible engineering principles in class. However, most of the refrigeration educational laboratories are still usinghydrofluorocarbons (HFCs) as working fluids, which are considered as greenhouse gases. This paper shows the procedureto adapt the new refrigerant R513A in a refrigeration system used for a cooling capacity educational laboratory. First, thepaper describes the organization of the laboratory session, and the characteristics of the different methods of coolingcapacity calculation taught to the master’s degree students. Then, the benefits of including new sensors in the experimentalsetup to obtain more accurate results are explained. Later, accurate new graphics and an equation to calculate the R513Acooling capacity are provided. Finally, the educational aspects worked with the students in this session, and each coolingcapacity method are assessed. The procedure explained in this paper can be used as a guide for introducing lower GWPrefrigerants in similar educational refrigeration laboratories.
