Distillation apparatus with porous membrane and heat pump

A distillation apparatus comprising:

• a feed water flow passage through which feed water to be distilled flows;
• a distillate flow passage through which distillate produced by distillation of said feed water flows;
• a distillation unit for distilling said feed water, said distillation unit comprising an evaporation part provided in said feed water flow passage, a condensation part provided in said distillate flow passage, and a hydrophobic porous membrane interposed between said evaporation part and said condensation part, said distillate flow passage introducing at least a portion of the distillate into contact with steam that passes through said hydrophobic porous membrane from said evaporation part, wherein said evaporation part, said condensation part and said hydrophobic porous membrane are integrated with one another;
• a heating unit for heating said feed water in said feed water flow passage, said heating unit being provided apart from said distillation unit;
• and
• a cooling unit provided apart from said distillation unit and having a heat pump for cooling said distillate in said distillate flow passage;
• wherein a heat absorption side of said heat pump of said cooling unit is disposed in said distillate flow passage whereas a heat radiating side of said heat pump is connected to an absorption heat source.
