摘要(Abstract):

提出了一种利用多级压缩机级间的废热,采用溴化锂吸收式制冷,来降低压缩机一级入口气体的温度的方法,达到了增加压缩机排气量的目的。并对系统进行了建模与模拟,当采用三段废热时,可将压缩机入口气体温度由35℃降到15℃。提高产能10%左右。
The method was put torword that it can reduce the temperature of compressor inlet gas and get the purpose of increasing compressor air displacement by using lithium bromide absorption chiller and the waste heat of multi-stage compressor inter-stage.The modeling and simulation of system are conducted.When three-stage waste heat is used,the temperature of compressor inlet gas can drop from 35℃ to 15℃.The productivity therefor can increase by about 10%.
