Absorber of water/LiBr absorption chiller is made up of horizontal tube banks, and its improvement is needed to get higher COP. To clarify the absorption process in these tube banks, a single row of horizontal pipe column is studied experimentally and analytically. The analytical model proposed in previous paper is further changed to conservative form according to the method of Shyy. It is confirmed that the mass balance of water is kept exactly by the present procedure. As for total absorption rate for the pipe column, agreement between experiment and numerical calculations are fairly good except the cases of 8 to 10 pipes at lower flow rate. The roughed pipes with different knurls on their surface were also tested in the experiment and it was found that knurl height of 0.5 mm was the most effective in absorption enhancement.
