ShareA comparison of R22, R134a, R410A, and R407C condensation performance in smooth and enhanced tubes. 2. Pressure drop.
Author(s) : ECKELS S. J., TESENE B. A.
Summary
Pressure drops are reported at four mass fluxes, at two saturation temperatures, and over a range of average qualities in the test tubes. The pressure drops for R410A were approximately 40% lower than those of R22 in both tubes. R407C had 10 to 20% lower pressure drops than R22, while R134a had slightly larger pressure drops than R22.
