Abstract: A laundry treating apparatus includes a 2-tank structure including a distillation tank and a washing tub. The laundry treating apparatus includes the washing tub that defines an inner space configured to receive laundry, the distillation tank configured to store liquid carbon dioxide, a compressor configured to receive gaseous carbon dioxide evaporated from the liquid carbon dioxide in the distillation tank, the compressor being configured to discharge the gaseous carbon dioxide, a cooler configured to cool the gaseous carbon dioxide discharged from the compressor and to supply the liquid carbon dioxide to the washing tub, and a controller configured to perform a control method. In some cases, a laundry treating apparatus includes a 3-tank structure including a storage tank, a washing tub, and a distillation tank.
