A drying apparatus is disclosed. The drying apparatus comprises: a drum; a compressor for compressing a refrigerant; a first temperature sensor provided at an air discharge port of the drum; a second temperature sensor provided at a refrigerant discharge port of the compressor; and a processor which, when a drying cycle for an object to be dried begins, compares a first temperature sensed by the first temperature sensor with a predetermined threshold temperature so as to obtain an operation frequency of the compressor, and when a second temperature sensed by the second temperature sensor reaches a predetermined first target temperature, adjusts the operation frequency of the compressor on the basis of a third temperature calculated on the basis of the first temperature and the second temperature.
