| 鐵路機(jī)械冷藏車制冷機(jī)組制冷劑替代的研究(28 卷) |
| 英文標(biāo)題 |
| Research on Refrigerant Substitution of Refrigerator Unit on Railway Mechanical Refrigerator Car |
| 摘要 |
| 通過對(duì)CFCS制冷劑R12替代的3個(gè)研究方向R134a替代、R22替代、R415B替代的制冷性能進(jìn)行比較分析，初步確定R415B替代、R22替代 (分換新壓縮機(jī)和改壓縮機(jī))、R134a替代4種方案，經(jīng)過比選擬采用綜合性能最好的R22改壓縮機(jī)方案做主要方案，以成熟可行的R134a方案做備用方案。最后通 |
