was considered (Sonnenrein et al., 2015). Fig. 7 shows the results for a combined integration of 150 g PCM foil into the evaporator and 500 g PCM elements into the spaces of the condenser of a commercial refrigerator, i.e. K-32122i (see Fig. 1, bottom). Compared to the foamed evaporator of K-12020S-1, the construction of the refrigerator’s free hanging rollbond evaporator a priori leads to a higher evaporator temperature.
