Abstract: An integrated solar absorption system is investigated in the present study. It consists of evacuated tube collectors, an auxiliary heater, a storage tank, and a LiBr-water absorption chiller. The system is conducted hourly from April to September. Variables of generator temperature, storage tank volume, and solar collector area are considered for the investigation. An optimisation method is performed to find the optimum point from energetic, exergetic, and economic viewpoints. By using the TOPSIS method, the optimum point is obtained at a generator temperature of 100°C, storage tank volume of 3.1 m³, and collector area of 30 m².
