Résumé

A LiBr-H2O triple-effect absorption chiller is currently under development in Korea. The chiller has three generators and a newly developed reverse-parallel solution flow was applied. Since the triple-effect absorption chiller has more system components and the flow of the solution is complicated, the control of the system is much more difficult than a conventional double-effect absorption chiller. Therefore, dynamic simulation is required to understand the characteristics due to the change of operation conditions. In this study, a dynamic simulation model has been developed for a reverse-parallel flow triple-effect absorption chiller, and the transient behaviours due to the change of operation conditions have been studied. The effects of the variation of the gas input, the cooling
water temperature, and the chilled water temperature have been investigated. The simulation results will be compared with the experiments. It is expected that this study will be able to supply important information in developing an optimal control method of the triple-effect absorption chiller.
