Frictional pressure drop vs. mean vapor quality during R152a flow boiling at G = 150, 200, 300, and 400 kg m−2 s−1. Saturation temperature of 20 °C (left), 15 °C (centre) and 10 °C (right) Full size image Also in this case, the experimental trend obtained reflects...
Using CYCLE_D-HX software, they found that R-463A has a higher normal boiling point and a significantly lower GWP than R-404A. R-463A can also be used in high ambient temperature environments due to its higher critical pressure and temperature. At low temperatures, R-463A has a 10% ...
