Abstract: The present invention relates to a method for controlling a clothes treating apparatus, the method comprising: a circulation step of circulating air by operating a fan; a heat exchange step of opening a refrigerant pipe by controlling an expansion valve, and circulating a refrigerant by operating a compressor; a circulation termination step of terminating the operation of the fan when the dryness level of clothes stored in a receiving part reaches a predetermined reference dryness level or when the elapsed time of the heat exchange step reaches a predetermined reference time; and a return step of closing the refrigerant pipe by controlling the expansion valve, and returning the refrigerant and lubricant in the refrigerant pipe to the compressor by operating the compressor.

Abstract: A clothes treatment apparatus and a method for controlling a clothes treatment apparatus are provided. The method may include feeding heated hot air to clothes or other items received in a drum, and dehydrating the clothes or other items by performing a first rotation cycle for rotating the drum at a first RPM for a predetermined period of time. The first RPM may be a RPM that allows a centrifugal force applied to the clothes or other items during rotation of the drum to exceed gravity.
