Abstract

A modified combined absorption-ejector cooling system use aquaammonia (NH3-H2O) refrigerant and evacuated solar collector as an input source has been investigated. Removable flash tank was added between the condenser and the evaporator. The modified cycle brings the advantage of improving in the ejector entrainment ratio. In addition, an improving in the coefficient of performance (COP) for the modified combined cycle, due to a reduction in the amount of flash gas delivered to the evaporator. A computer program has been developed to simulate the refined cycle. The results of the proposed cycle design have compared with the combined cycle (ejector-absorption) without flash tank. The results showed that the COP was improved by adding flash tank.
