本发明公开了一种空调装置及其控制方法。空调装置具有用于控制加载到压缩机的电机(2a)的功率水平的功率水平控制单元(6)。功率水平控制单元(6)包括用于将第一水平功率加载到压缩机电机(2a)的第一加载单元(6a)和用于将第二水平功率加载到压缩机电机(2a)的第二加载单元(6b)。如果工作循环对应于负载操作，功率水平控制单元(6)通过第一加载单元(6a)加载用于压缩致冷剂的第一水平功率。另外，如果压缩机的工作循环对应于卸载操作，功率水平控制单元(6)通过第二加载单元(6b)加载小于第一水平功率的第二水平功率。由此，本发明的优点在于其能够降低在卸载操作过程中由压缩机电机引起的不需要的功率消耗。 Disclosed herein is an air conditioning unit and method of operating the same. The air conditioning unit has a power level control unit ( 6 ) for controlling the level of power supplied to a motor ( 2 a) of a compressor. The power level control unit ( 6 ) is comprised of a first supplying unit ( 6 a) for supplying first level power to the compressor motor ( 2 a), and a second supplying unit ( 6 b) for supplying second level power to the compressor motor ( 2 a). If an operation cycle of the compressor corresponds to a loading operation, the power level control unit ( 6 ) supplies first level power for compressing a cooling agent through the first supplying unit ( 6 a). Further, if an operation cycle of the compressor corresponds to an unloading operation, the power level control unit ( 6 ) supplies second level power less than the first level power through the second supplying unit ( 6 b). Therefore, the present invention is advantageous in that it can reduce undesirable power consumption caused by the compressor motor during the unloading operation.
