Beschreibung
Zusammenfassung:	The invention provides a refrigerating device. Through a simple structure, a required cooling performance is maintained, and the increasing of electric energy and noise caused by the useless increasing of frequency of an inverter is inhibited. The refrigerating device (100) comprises an inverter (102) for providing electric power to a compressor (101); and the frequency increasing/decreasing speedof the inverter (102) is fixed in a first frequency zone (20-55 Hz) and is variable in a second frequency zone (55-80 Hz), which has higher frequency compared with the first frequency zone. 本发明提供制冷装置，该制冷装置通过简易的结构，能够在维持所需的冷却能力的同时，抑制逆变器频率的无益的上升所引起的电能和噪音的增加。制冷装置(100)包括对压缩机(101)供给电力的逆变器(102)，逆变器(102)的频率的升降速度在第一频率区域(20～55Hz)中固定，且在比该第一频率区域高的第二频率区域(55～80Hz)中可变。
