A method of controlling a laundry treatment apparatus having a tub configured to store wash water, a drum rotatably-mounted in the tub and configured to store laundry, and through-holes perforated in the circumference of the drum, the method comprising: a drying operation, a motion execution operation for rotating the drum during implementation of the drying operation, and a cooling water supply operation for supplying water to cool an inner circumferential surface of the tub during implementation of the motion execution operation; wherein the drying operation includes: a circulation process for resupplying air discharged from the tub back into the tub, an exhaust process for discharging some of the air resupplied back into the tub to outside of the tub, a suction process for mixing circulated air via the circulation process with air from outside of the tub, and a heating process for heating mixed air, the mixed air being acquired via the circulation process and the suction process; wherein the air discharged to outside of the tub in the exhaust process moves to the outside of the laundry treating apparatus, and wherein the motion execution operation includes: rotating the drum at a first Revolutions Per Minute, the first RPM being a number of RPM at which the centrifugal force on the laundry is greater than the weight of laundry; and rotating the drum at a second RPM, the second RPM being greater than the first RPM. a drying operation, a motion execution operation for rotating the drum during implementation of the drying operation, and a cooling water supply operation for supplying water to cool an inner circumferential surface of the tub during implementation of the motion execution operation; wherein the drying operation includes: a circulation process for resupplying air discharged from the tub back into the tub, an exhaust process for discharging some of the air resupplied back into the tub to outside of the tub, a suction process for mixing circulated air via the circulation process with air from outside of the tub, and a heating process for heating mixed air, the mixed air being acquired via the circulation process and the suction process; wherein the air discharged to outside of the tub in the exhaust process moves to the outside of the laundry treating apparatus, and wherein the motion execution operation includes: rotating the drum at a first Revolutions Per Minute, the first RPM being a number of RPM at which the centrifugal force on the laundry is greater than the weight of laundry; and rotating the drum at a second RPM, the second RPM being greater than the first RPM. a circulation process for resupplying air discharged from the tub back into the tub, an exhaust process for discharging some of the air resupplied back into the tub to outside of the tub, a suction process for mixing circulated air via the circulation process with air from outside of the tub, and a heating process for heating mixed air, the mixed air being acquired via the circulation process and the suction process; wherein the air discharged to outside of the tub in the exhaust process moves to the outside of the laundry treating apparatus, and wherein the motion execution operation includes: rotating the drum at a first Revolutions Per Minute, the first RPM being a number of RPM at which the centrifugal force on the laundry is greater than the weight of laundry; and rotating the drum at a second RPM, the second RPM being greater than the first RPM. rotating the drum at a first Revolutions Per Minute, the first RPM being a number of RPM at which the centrifugal force on the laundry is greater than the weight of laundry; and rotating the drum at a second RPM, the second RPM being greater than the first RPM.
