USE OF LOW TEMPERATURE ENERGY SOURCES IN AQUA-AMMONIA ABSORPTION REFRIGERATION SYSTEMS

摘要

In this study, the use of low temperature (85-110℃) energy sources in ammonia-water absorption refrigeration systems was investigated, and a thermodynamic analysis of the ARS was performed. The system consists of the condenser (drum), evaporator, absorber (drum), pump expansion valves, reboiler, distillation column (top, bottom, feed) with refrigerant and mixture heat exchangers. Using the mathematical model, the system variations of circulation ratio and coefficient of performance of the cycle with design and working parameters are obtained. The results are compared with results given in the literature, and optimum working conditions are determined.
