摘要： An object is to improve cooling efficiency while preventing an abnormal increase in pressure of a high side in a cooling apparatus which uses so-called carbon dioxide as a refrigerant. The cooling apparatus comprises a refrigerant circuit in which a compressor, a gas cooler, pressure reducing means, an evaporator and the like are connected in an annular shape, and carbon dioxide is sealed as a refrigerant. In a stable running state in which a temperature of a space to be cooled by the evaporator is cool, time after a start of the compressor until a difference between outlet and inlet temperatures of the evaporator becomes within 1 degree is 5 minutes or more to less than 20 minutes.

摘要： There is provided a cooling apparatus which can prevent an abnormal increase in pressure of a high side at the time of starting. The cooling apparatus comprises: a refrigerant circuit which uses carbon dioxide as a refrigerant; and a control device which controls a speed of rotation for the compressor between predetermined lowest and highest speeds. The control device runs the compressor by holding a predetermined start-time holding speed of rotation lower than the lowest rotational speed for a predetermined time before the lowest rotational speed is reached after the compressor is started.

摘要： There is provided a cooling apparatus which can improve cooling efficiency of an evaporator while preventing freezing of articles housed in a cooled space thereof. The cooling apparatus comprises: a control device which controls a compressor; and a temperature sensor in the chamber which can detect a cooled state in a refrigerator main body to be cooled by the evaporator. The control device stops running of the compressor if the compressor is continuously run for a predetermined time, and changes the continuous running time of the compressor for stopping the same based on a temperature in the chamber of the refrigerator main body detected by the temperature sensor in the chamber.
