针对高温发生器发生温度过高而引起的腐蚀影响三效溴化锂吸收式制冷系统推广应用的难题,提出了在基本逆串联三效溴化锂制冷系统中附加一个压缩机的系统方案,并经分析认为在蒸发器和吸收器之间布置压缩机最佳。这种增压吸收式循环,补偿相当于制冷量2%~10%的电能即可使驱动热源温度降低约5~40℃,达到与传统循环相当的制冷系数。
Wider application of a triple-effect absorption refrigerating machine using the lithium bromide-based working fluid is limited for the corrosion problem resulted from over high temperature in the high pressure generator. Proposes adding a compressor to basic in-counter-series triple-effect lithium bromide refrigerating system, and concludes that the best position is between the evaporator and the absorber. This pressur isation-absorption cycle uses an equivalent to 2% - 10% of cooling capacity decreasing the temperature of driving heat source 5-40℃ with the cooling coefficient near to that of the traditional cycle,
