| Abstract: | Performance of an absorption heat pump (type II) driven by solar energy is studied. Based on their different heat and mass transfer characteristics, the mathematical models of solar collector and unit components of an absorption heat pump system are constructed. The regressing process of thermophysical properties of working medium (LiBr H 2O solution) is presented. Under various working conditions, a numerical simulation on performances of the absorption heat pump is carried out. By solving the non linear heat and mass transfer equations, the system's performances under different environment temperature, absorption temperature and generation temperature are obtained. |
