Résumé

This study was conducted in order to investigate the changes of the performance of a hot water absorption chiller as influenced by the characteristics of the heating tubes inserted in its generator. The absorbent and the refrigerant flowing inside the generator were 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 were measured. Also, the pressure of the generator and the flow rate of the refrigerant and the absorbent we measured. A Labview program was used for the measurements. Tests were conducted on different types of heating tubes using the same experimental conditions and the values of the overall heat transfer coefficient were determined. With this, the type of heating tubes that resulted to the improvement of the performance of the absorption chiller can be identified.
