摘要: |
本文在自行研制的半导体制冷膜蒸馏系统上,分析并计算了半导体制冷膜蒸馏系统的能耗。半导体制冷性能和膜通量在热液高温区域都随热液温度陡增,但一味地增加热液温度会带来系统的额外能耗。在相同热液温度下,膜通量的变化趋势与系统吨水能耗的变化趋势相反。热液温度75℃,输入电流8A增大到12A时的系统吨水能耗几乎呈线性增长,能耗的增量基本维持在8.5%。为确定半导体制冷与膜蒸馏系统匹配时的最优耦合工况,给出了两项判定准则,即最佳匹配工况准则和最佳吨水能耗准则。对比两种判定准则发现,两者的经济性指标一致。 |
Based on the self-developed by semiconductor refrigeration membrane distillation system, the energy consumption of the semiconductor refrigeration membrane distillation system was analyzed and calculated. Semiconductor refrigeration performance and membrane flux jump as the hydrothermal temperature in high temperature regional. But blindly increasing hydrothermal temperature will bring additional energy consumption system. Under the same hydrothermal temperature, the change trend of membrane flux and the system the change trend of tons of water energy consumption on the contrary. The tons of water energy consumption of system is almost linear growth,when the hydrothermal temperature is 75 ℃, the input current increases to 12A from 8A, energy consumption increment of basic remain at 8.5%. In order to determine the semiconductor refrigeration and membrane distillation system matching the optimal coupling condition, the two criteria is presented, the best matching condition and the best tons of water energy consumption standard. Contrast the two kinds of criteria and comparison,economic indicators are consistent. |
