In the considered system the geothermal fluid is transported to the VAC where water and ammonia are used as an absorbent and a refrigerant respectively. Energy and exergy analyses methods are utilised to assess the performance of the whole system while some operational properties of the VAC such as pressure temperature ammonia concentration and flow rate are determined. Based on the parametric studies optimum operating conditions of the VAC are obtained to be 30°C 90°C and 2°C for the condenser boiler and evaporator respectively. Under these conditions the system has a coefficient of performance (COP) value of 0.30 with a simple payback period of 6.4 years the highest exergy destruction occurs within the absorber with a rate of 38.2%. © 2020 Elsevier B.V.
