This paper is an experimental study dealing with the basic boiling heat transfer for a solar-powered absorption chiller. Three kinds of surface-worked heat transfer tubes were tested in bulk liquid or in narrow spaces under several reduced pressure conditions, and the saturated boiling heat transfer characteristics were determined. The obtained data were compared with the data on smooth surface tubes of the same conditions. The experimental results show that the surface-worked tubes in bulk liquid do not get a greater boiling heat transfer promotion than that in the case of the smooth tube, but the surface-worked tubes with narrow spaces get considerable heat transfer enhancement in comparison to the than case without narrow spaces, and a new correlation equation is proposed.
