补充资料:等温压缩(isothermalcompression)
等温压缩(isothermalcompression)
气体温度在压缩的过程中保持不变称为等温压缩。在理想情况下,可看成是可逆压缩过程。工程上的处理为压缩机加水冷却系统,经压缩后的高温气体经过冷却水,把压缩热给冷却水带走,在等温压缩中,气体的熵变小,这也是气体制冷和液化的最关键一步。
在温度T下将气体从状态1等温压缩到状态2,压机做功W,冷却水带走压缩热Q,焓的变化为H2-H1,可得H2-H1=W-Q则
Q=W (H2-H1)
气体的熵降为`S_2-S_1=\frac{Q}{T}=\frac{W (H_1-H_2)}{T}`。所以此时可通过等熵膨胀或等焓膨胀来降温以达到制冷的目的。
