Abstract:
Ammonia absorption by and desorption from lithium chloride at different pressures has been studied using high-pressure differential scanning calorimetry, for application in a high-lift high temperature chemical heat pump. The measurements were performed under isobaric as well as under isothermal circumstances. Clausius-Clapeyron plots were constructed and used to calculate the thermodynamic parameters and to determine the stability regions of the differnt complexes. Controversies in literature as to the real existing phases are resolved
