| Abstract: | Up to now the industrial systems for energy recovery at the level of 130°C have been using water solutions of lithium bromide. These solutions present two problems: risks of crystallisation and corrosion. To avoid these risks, the system water-glycerol has been selected.The interest of the proposed can be seen through the theoretical simulation of the absorption heat pump cycle. The simulation results indicate that it is possible to achieve an energy upgrading of 50°C at the absorber. The efficiency coefficient depends on the high and low pressure, but not too much on the performance of the condenser. High values of low pressure lead to the best performance. |
