The performance of a plate heat exchanger for using liquid solution the absorption chiller was analyzed. The objectives of this paper are to measure the heat transfer and pressure drop of the plate heat exchanger for absorption system applications. Three types of plate heat exchangers with different chevron angles are tested in the present experiment. The working fluid is H2O/LiBr solution with the LiBr concentration range of 55% in mass. The results show that the overall heat transfer coefficient increases linearly with increasing Re. This work is a basic study of a cycle in which LiB aqueous solution, which has been diluted through the absorption of water vapor in the absorber of an absorption chiller, is made concentrated before reaching the regenerator.
