Patent ID: 7191609

Claim:
A cooling apparatus comprising: a refrigerant circuit constituted by sequentially connecting a compressor, a gas cooler, diaphragming means and an evaporator through a pipe; a control device which controls the compressor; and a cooled state sensor capable of detecting a cooled state of a space to be cooled by the evaporator, wherein: the control device includes control means for changing a rotational speed of the compressor based on a temperature of the cooled space detected by the cooled state sensor, and for stopping the compressor when the cooled space is cooled to a set lower limit of the temperature of the cooled space, wherein said control device further includes control means for forcibly turning off the compressor if the compressor is continuously run for a predetermined time, and for changing the continuous running time of the compressor based on a temperature of the cooled space detected by the cooled state sensor.
