Résumé

Pool boiling is a space efficient method with high heat transfer coefficients for cooling of several applications, for example power electronics. In previous studies, refrigerants such as FC72 and R113 have been used, which have a high GWP (global warming potential). In this study, the refrigerant used is 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone or also known by its trade name Novec 649. It has similar thermal properties as FC-72 and R-113, but has a very low GWP of 1. An experimental setup is constructed to measure pool boiling heat transfer on a horizontal plate. The measured boiling curve corresponds to reported measurements of other authors for similar refrigerants. The measurements are compared with three available correlations from literature on pool boiling. None of the correlations represent the boiling measurement data with adequate accuracy.
