Experimental study on refrigeration performance of semiconductor in new membrane distillation component

The new membrane distillation component with the semiconductor refrigeration is presented.Based on the principle of semiconductor refrigeration,choosing the best cooling way-water cooling,the effect of the change of water area on the semiconductor refrigeration components＇ properties is studied in the same condition.The result shows that the temperature and the agitation of the cooling water have greater impact on their refrigerating performance.When semiconductor refrigeration components run in certain conditions,the refrigeration surface remaines stable at-3.2 ℃.This can satisfy the membrane distillation for cold end conditions,which proves the semiconductor refrigeration component can be coupled with membrane distillation process.And this also provides the semiconductor refrigeration component experimental basis in membrane distillation experiment application.
