The objective of this study is to investigate the changes of the performance of steam heated generator of absorption chiller as influenced by the characteristics of the heating tubes inserted in its generator. The absorbent and the refrigerant flowing inside the generator are LiBr and water, respectively. The experiments were done based on a 58% absorbent concentration. In the experiments, the inlet and outlet temperatures of the absorbent and the inlet and outlet temperature of the refrigerant in the generator are measured. Also, the pressure of the generator and the flow rate of the refrigerant and the absorbent we measured. Tests were conducted on different types of heating tubes under the same experimental conditions and the values of the overall heat transfer coefficient are measured.
