摘要
通过对单级压缩与双级压缩实际制冷循环系统各过程火用损失的计算 ,找出循环过程的薄弱环节 ,提出改进循环热力特性的可行性 ,得出单级压缩制冷循环中蒸发器火用损最大 ,冷凝器火用损次之 ,双级压缩制冷循环中压缩机火用损最大 ,蒸发器火用损次之 。
The paper finds out circle process's thin moments and provides to improve probability of thermal circle nature through every exergy cost calculations in single and double compression practical refrigerative circle system .In single compression refrigerative circle, evaporator's exergy cost is most, condenser's is next. In double compression refrigerative circle, compressor's exergy cost is most, evaporator's is next . Analysis and quests in improving circle efficiency are pat forword.
