两种吸收-喷射复合制冷循环的对比研究
Performance Comparison of Two Combined Absorption-ejector Refrigeration Cycles
摘要
Abstract
The performance of two combined absorption-ejector refrigeration cycles driven by low grade heat are compared. In the first cycle, part of the saturated liquid refrigerant in a condenser outlet is pressurized to the saturated pressure corresponding to generation temperature by a refrigerant pump, and then it is heated to be saturated high - pressure vapor in a boiler. Then this fluid ejects the superheated vapor coming of precooler to the condensing pressure. In the second cycle, part of vapor out from generator ejects the vapor from an evaporator to absorbing pressure. For the two cycles using NH3 - NaSCN as the working pair, simulation results show that performance of the former cycle is at least 15% higher than that of the latter one and the relative increase ratio increases as evaporation temperature or generation temperature decreases.关键词
