摘要
以氨双级压缩制冷循环为例,在确定最佳中间温度时,考虑实际制冷循环中的摩擦因素;以实际制冷系数的最大值为依据,经过计算与分析提出了最佳中间温度又一经验计算式,并分析了其计算结果的误差范围。
This paper proposes a new empirical formula for determination of optimum interstage temperature of two stage compression cycles. This formula is optimized with the maximum COP of real cycle in which the influence of friction factor of the compressors is considered. The error range is also discussed in this paper.
