Performance analysis of the natural mixture R744/R600a refrigeration cycle

2010 International Conference on Mechanic Automation and Control Engineering, 2010
Environmental conservation issue advances the refrigerant substitute for the Freons. Natural working fluid must be a perfect choice. Therefore, natural friendly refrigerants R744 and R600a are selected in this research to be a binary mixture. Such a mixture can weaken their shortcomings by decreasing high heat rejection pressure as that of pure R744 ...

A molecular dynamics simulation study on condensation of R600a refrigerant

AIP Conference Proceedings, 2018
Molecular Dynamics (MD) simulations have been employed to study the homogeneous condensation phenomena of isobutane used as a R600a refrigerant in the vapor compression refrigeration system. The molecular system consists of the superheated vapor isobutane in a cubic simulation cell with periodic boundary conditions in all three dimensions.
