制冷系统模拟不收敛？ 楼上指出的问题是很有道理，重新表述如下： 1，做的是r 600a、r23、r14混合工质的自复叠系统，现在已经收敛。 2，出现问题1提示结果可用但是有error： mix1处 the following messages were issued during report generation: ** error flash results are within tolerance, but may be unsatisfactory because extrapolated eos vapor volume root was used for property calculations. calculated properties may be unreliable due to flash problems. ** error flash results are within tolerance, but may be unsatisfactory because extrapolated eos vapor volume root was used for property calculations. calculated properties may be unreliable due to flash problems. ** error flash results are within tolerance, but may be unsatisfactory because extrapolated eos vapor volume root was used for property calculations. calculated properties may be unreliable due to flash problems. ** error flash results are within tolerance, but may be unsatisfactory because extrapolated eos vapor volume root was used for property calculations. calculated properties may be unreliable due to flash problems. ** error flash results are within tolerance, but may be unsatisfactory because extrapolated eos vapor volume root was used for property calculations. calculated properties may be unreliable due to flash problems. ** error flash results are within tolerance, but may be unsatisfactory because extrapolated eos vapor volume root was used for property calculations. calculated properties may be unreliable due to flash problems. ** error flash results are within tolerance, but may be unsatisfactory because extrapolated eos vapor volume root was used for property calculations. calculated properties may be unreliable due to flash problems. ** error flash results are within tolerance, but may be unsatisfactory because extrapolated eos vapor volume root was used for property calculations. calculated properties may be unreliable due to flash problems. ** error flash results are within tolerance, but may be unsatisfactory because extrapolated eos vapor volume root was used for property calculations. calculated properties may be unreliable due to flash problems. ** error flash results are within tolerance, but may be unsatisfactory because extrapolated eos vapor volume root was used for property calculations. calculated properties may be unreliable due to flash problems. ** error flash results are within tolerance, but may be unsatisfactory because extrapolated eos vapor volume root was used for property calculations. calculated properties may be unreliable due to flash problems. ** error flash results are within tolerance, but may be unsatisfactory because extrapolated eos vapor volume root was used for property calculations. calculated properties may be unreliable due to flash problems. ** error flash results are within tolerance, but may be unsatisfactory because extrapolated eos vapor volume root was used for property calculations. calculated properties may be unreliable due to flash problems. ** error flash results are within tolerance, but may be unsatisfactory because extrapolated eos vapor volume root was used for property calculations. calculated properties may be unreliable due to flash problems. ** error flash results are within tolerance, but may be unsatisfactory because extrapolated eos vapor volume root was used for property calculations. calculated properties may be unreliable due to flash problems. ** error flash results are within tolerance, but may be unsatisfactory because extrapolated eos vapor volume root was used for property calculations. calculated properties may be unreliable due to flash problems. ** error flash results are within tolerance, but may be unsatisfactory because extrapolated eos vapor volume root was used for property calculations. calculated properties may be unreliable due to flash problems. 2，设置参数如下：系统只设置两个高低压2mpa，o.2mpa，压缩机入口270k，出口380k，冷凝器300k，一级换热量560w。二级460w。计算出来蒸发温度180k，皆与文献吻和，问题就是设置蒸发器出入口设置10度温差时，制冷量达到300w，比文献大好多。 以上谢谢！ 查看更多
