ABSTRACT:
A distillation apparatus includes a distillation unit for distilling feed water. The distillation unit includes an evaporation part, a condensation part and a hydrophobic porous membrane interposed between the evaporation part and the condensation part, which are integrated with one another. A heating unit for heating the feed water and a cooling portion for cooling distillate produced by distillation of the feed water are provided apart from the distillation unit. One or both of the heating unit and the cooling unit are provided with a heat pump. With this construction, an additional heater does not need to be provided, and the distillation unit and both of the heating unit and the cooling unit can be changed in size and performance independently of each other, so that the overall size of the distillation apparatus can be reduced.
