逆串联TC式三效溴代理吸收式制冷循环分析

STUDY ON THE COUNTER SERIES CONNECTION TC TRIPLE EFFECT LITHIUM BROMIDE ABSORPTION REFRIGERATION CYCLE

根据本课题组人员完成的三效溴化锂吸收式制冷循环计算程序，对一种逆串联式三效循环进行了热力计算分析。结果表明，其发生温度约在２００～２２０°之间，发生压力约在２～４×１０５Ｐａ之间，其ＣＯＰ比双效制冷循环高约４０％。因而，逆串联ＴＣ循环是一种既具有较高的热力性能系数，又具有较低的发生温度、发生压力的三效循环。

Using the program for triple effect lithium bromide absorption refrigeration thermodynamic calculating which developed by our research group, we studied a type of cycle named of counter series connection TC lithium bromide absorption refrigeration cycle. The result indicted found that its generator temperature is about 200～220°, its generator pressure is about 4×105 Pa, and its COP value is about higher by 40% then double effect lithium bromide absorption refrigeration's. So the cycle is a more valuable cycle which has more higher COP value and lower generator temperature and pressure.
