摘要
设计了一种新型的半导体制冷空气隙膜蒸馏系统,将具有半导体制冷的冷腔与膜蒸馏系统的热腔有机地结合起来。实验研究了半导体输入电流、冷却水流量及热液温度对通量的影响。实验表明:冷却水流量900 L/h,输入电流8 A时的冷壁温度平均为5℃,制冷面各测点的温差最大只有0.5℃,制冷面温度均匀;实验工况8~12 A,冷却水流量300L/h时,膜通量随半导体输入电流的增大而增大。本文的研究为小型半导体制冷空气隙膜蒸馏系统的理论与应用研究奠定了基础。
The paper designs a new semiconductor refrigeration air gap membrane distillation system,which is composed organically of the cold chamber of semiconductor refrigeration and the hot chamber of membrane distillation system.The influence of membrane flux on the input current of semiconductor,cooling water flow and hydrothermal temperature is investigated experimentally.As shown the experiments:the flow of cooling water is 900 L/h,the input current of semiconductor refrigeration is 8 A,the average temperature of the cold wall is 5℃,the maximum temperature difference of every measuring point in the cold wall is 0.5 ℃,the cold wall is temperature uniformity;The input current of semiconductor refrigeration is 8~12 A,the flow of cooling water is 300 L/h,the membrane flux increases with the increase of the input current of semiconductor.These results lay a foundation for theory and applicatioon research on small air gap membrane distillation system of semiconductor refrigeration.
