Abstract

The present disclosure relates to a laundry treating apparatus including a pressure vessel, a storage tank storing carbon dioxide therein, and supplying carbon dioxide to the pressure vessel, and a distiller for vaporizing liquid carbon dioxide of carbon dioxide discharged from the pressure vessel to remove foreign substances therefrom, and then, liquefying vaporized carbon dioxide and supplying liquefied carbon dioxide to the storage tank, wherein the distiller includes a distillation tank located below the pressure vessel and storing carbon dioxide discharged from the pressure vessel to remove foreign substances dissolved in carbon dioxide discharged from the pressure vessel, a circulation flow path located outside the distillation tank to circulate liquid carbon dioxide stored in the distillation tank, and an external heat exchanger positioned on the circulation flow path to heat liquid carbon dioxide passing through the circulation flow path using external heat.
