| description | The invention provides a refrigerating device capable of properly controlling valve opening degree of an expansion valve when a compressor is started and reducing a starting load. The refrigerating device (R) is characterized in that the compressor (11), an air cooler (28), the expansion valve (32) and an evaporator (33) are formed to be a refrigerant loop (1), a high-pressure side of which is formed to be super-critical pressure; the refrigerating device is provided with a controlling device used for controlling the compressor (11) and the expansion valve (32); and the controlling device is used for changing valve opening degree of the expansion valve (32) when the compressor (11) is started based on external temperature of air and for expanding valve opening degree of the expansion valve (32) in the case of the high temperature of external air and lessening valve opening degree of the expansion valve (32) in the case of the low temperature of external air. |
