氨双级压缩制冷最佳中间温度计算

peratures for Two-stage Compression System(R717)

本文编制了通用计算程序以分别求取最大制冷系数、最小高低压缸理论容积、高低压级排汽温度相同、高低压缸理论容积比为给定值,四种情况下的最佳中间温度。

This paper gives the universal programs to calculate four different interstage temperatures when the coefficient of performance (COP) reachs maximum; the sum of high pressure compressor volume (V_h) and low pressure compressor volume (V_1) reachs minimum; the temperature at outlet of H. P. comp. is equal to the temperature of L. P. comp.; the ratio of V_h to V_t is constant.
