Refrigerant 410a pressure.
The higher the GWP the more harm the refrigerant does to the climate. R-410A has a GWP of over two-thousand whereas R-32 has a GWP of only six-hundred and seventy-five. While R-32 isn’t perfect it is a lot better then R-410A. That is why we are beginning to see a rise of usage of R-32 in the European Union and here in the United …
Furthermore, the pressure drop for R-410A was about 30% lower than that of R-22 during evaporation. The quantitative differences in the pressure drops between R-410A and R-22 were mainly attributed to the differences in the vapor densities of two refrigerants. The larger the vapor density, the smaller the pressure drop of a refrigerant.Does alcohol raise blood pressure? Learn about how alcohol effects blood pressure at HowStuffWorks.
