Ki-Jung Park, Auteur ; Dong Gyu Kang, Auteur ; Dongsoo Jung, Auteur |In this study, external condensation heat transfer coefficients (HTCs) of HFC134a and R1234yf are measured on a plain, low fin, and Turbo-C tubes at the saturated vapor temperature of 39 °C with the wall subcooling of 3–8 °C. R1234yf is a new al[...]

Performance of virtually non-flammable azeotropic HFO1234yf/HFC134a mixture for HFC134a applications
Yohan, Lee, Auteur ; Dong Gyu Kang, Auteur ; Dongsoo Jung, Auteur |In this study, ‘drop-in’ performance of HFC134a, HFO1234yf and HFO1234yf/HFC134a mixture at three compositions of 5%, 10%, and 15% HFC134a is measured in a heat pump bench tester under summer and winter conditions. Test results show that the COP[...]
