RP-63 — Refrigerant Forced Convection Condensation Inside Horizontal Tubes

- ASHRAE
High vapor velocity condensation inside a tube was studied analytically. The von Karman universal velocity distribution was applied to the condensate flow, pressure drops were calculated using the Lockhart-Martinelli method, and heat transfer coefficients were calculated from the momentum and heat transfer analogy. Subsequently, the analysis was reduced to an accurate, but simplified form, to facilitate calculations.
Experimental data for refrigerants R-12 and R-22 condensing in a 0.315 in. I. D. tube were obtained for various mass fluxes. On the basis of the data and analysis, a simplified non-dimensional presentation of the results evolved.
