The present invention relates to a fresh water production apparatus using membrane distillation. More specifically, the present invention relates to a fresh water production apparatus using membrane distillation, which comprises: a seawater storage tank for storing introduced seawater; a heating device for heating seawater supplied from the seawater storage tank; a membrane distillation module which has a hollow fiber distillation membrane in a vacuum state and in which seawater supplied via the heating device passes through the hollow fiber distillation membrane and steam is generated; and a heat exchanging device in which the steam generated from the membrane distillation module and the seawater supplied from the seawater storage tank are heat-exchanged, thereby generating fresh water. Accordingly, a degree of integration of membrane is improved, thereby increasing production of fresh water, and simultaneously energy efficiency can be maximized using seawater preheated by means of heat exchange. |
