Abstract:
Einstein cycle is a kind of single-pressure absorption refrigerator, using n-butane-ammonia-water as working fluids, driven by low grade heat source.The original cycle was improved, in which two solution heat exchangers were configured respectively before the generator and the evaporator to modify thermal performance of the refrigeration equipment.By using the exergy analysis method, the exergy losses of all thermal parts of the refrigerator were obtained, and the theoretical basis for improving design was given.The energy-saving places and the correlative further improvements were presented to minimize the exergy losses and optimize the whole refrigeration cycle.In addition, the generator and the condenser were the main parts where exergy losses existed.
