Abstract:
This thesis proposes modified absorption refrigeration systems. The first system is the combined steam ejector -absorption refrigeration system I. It uses the steam ejector located in the system between the high and low temperature generators to induce the refrigerant vapor from the evaporator for increasing refrigerating effect. The system II is improved from the system I by using the waste heat from the absorber to heat the refrig~rant vapor from the evaporator before it is induced by the ejector. The third system is the combined absorption and vapor-compression refrigeration system. It uses a turbo to combine the absorption cycle with the vapor-compression cycle. The potential energj between the generator and the condenser of the absorphon cycle is used to drive the compressor of the vapor-compression cycle. The turbo absorption-recompression refrigeration system is the fourth system: the turbo is used to compress a part 'of the refrigerant vapor from the generator in order to reheat the LiBr-KO solutions in the generator. Consequently, the utilized energy in rhe system is used efficiently. The last system is the combined turbo-absorption refrigeration system. It uses the potential energy between the generator and the condenser to drive the turbo in order to increase the refrigerating capacity. Mathematical models, which assessments are based on steady state themodynamic analysis are developed to study the characteristics and the theoretical coefficient of performance (COP) of their systems. COPs of the first and second systems are less than that of the convsntional double-effect absorption refrigeration system. COPs of last three systems are higher than that of the conventional absorption refrigeration system.
