摘要：Thermodynamic analysis of parallel flow single and double effect LiBr-H2O absorption system has beencarried out. In the single effect cycle, the refrigerant leaving the evaporator is divided to flow in parallel and getabsorbed partly in a heat recovery absorber and the remaining in a heat rejecting absorber. This reduces heat load of thegenerator to a great extent and hence, improves COP of the cycle. Similarly in the double effect parallel flow cycle, thesolution leaving the absorber is divided into two parts, one being sent to the main generator and the other to thesecondary generator. Such type of arrangement in the double effect system increases COP of the cycle as compared tothe series flow cycle. The refrigerant distribution ratio (RDR) in the single effect refrigerant-parallel flow cycle and thesolution distribution ratio (SDR) in the double effect solution-parallel flow cycle have been optimized. Theoptimization results, corresponding to the maximum COP, yield: RDR=0.30 and SDR=0.45. A comparative studybetween the single effect simple cycle, single effect cycle using heat recovery absorber, double effect parallel flowcycle and double effect series flow cycle has been presented. The analysis has been done by varying evaporatortemperature (Te) from 5oC to 12.5oC and condenser/absorber temperature (Tc) from 30oC to 40oC.
