PROBLEM TO BE SOLVED: To solve a problem in an operation of a compressor by a conventional invertor device that following capability can not be sufficiently secured though its purpose is promotion of increase of output frequency in shortage of refrigerating capacity and decrease of the output frequency in excess of refrigerating capacity. SOLUTION: This refrigerating device comprising a refrigerant circuit constituted by communicating a compressor, a condenser, a throttle means and an evaporator by refrigerant pipes, and the invertor device of variable output frequency for driving the compressor, further includes a compressor operation time detecting means, a compressor target stop time setting means, a target low pressure-side pressure setting means, a low pressure-side pressure detecting means, and an invertor control means, thus the frequency of the invertor device is effectively changed, and the refrigerating device of high following capability of an indoor temperature and an operating state can be provided.
