Shell-side condensation heat transfer of R134a. 2. Enhanced tube performance.

Author(s) : HUBER J. B., REWERTS L. E., PATE M. B.

Summary

Shell-side heat transfer coefficient data are presented for the condensation of R134a on tube bundles constructed from two different enhanced tube geometries. The tube bundles tested were five rows wide by five rows deep and had a staggered tube arrangement with a horizontal pitch of 22.2 mm and a vertical pitch of 19.1 mm. The data were obtained at a refrigerant saturation temperature of 35 deg C over a bundle heat flux range of 18 to 40 kilowatts/m2. Average condensing heat transfer coefficients for the bundle as well as average condensing heat transfer coefficients for the middle tube of each row were calculated.
