Experimental Investigation and Correlation Assessment of Condensation Heat Transfer for Low-GWP Alternative Refrigerants in a Horizontal Smooth Tube

Energies
Condensation heat transfer and frictional pressure drop of R410A, R455A, R454C, and a newly proposed ternary low-GWP (Low-Global Warming Potential) refrigerant (R1234yf/R13I1/R32) were experimentally investigated in a horizontal smooth tube.

Dry-Cooled Rankine Cycle Operated With Binary Carbon Dioxide Based Working Fluids

SolarPACES Conference Proceedings
The dry-cooled Rankine cycle working with a zeotropic mixture of CO2+C6F6 is influenced by the ambient temperature as air is used as the heat sink. Varying heat sink temperatures allow for operating the cycle under sliding condensation pressure which ...
