囲第１項記載の冷凍装置。[Claims for Utility Model Registration] (1) A compressor that compresses refrigerant, a condenser that liquefies the refrigerant gas compressed by this compressor, an expansion valve that decompresses and expands the refrigerant liquefied in this condenser, and this decompressor. An evaporator that evaporates the expanded refrigerant, exchanges heat with the object to be cooled in the refrigerator, and returns the refrigerant to the compressor, and a frequency that supplies electric power to the drive motor that drives the compressor by varying the frequency. A converter, a low-pressure force detector that detects the low-pressure refrigerant pressure sucked into the compressor and compares it with a predetermined pressure setting value to determine the frequency of the frequency converter, and houses the object to be cooled. A refrigeration system comprising a temperature sensor that detects the temperature inside the refrigerator and, when the temperature is higher than a set value, lowers the pressure set value of the low pressure force detector by a predetermined amount. (2) The refrigeration system according to claim 1, which is characterized in that when the temperature inside the refrigerator is higher than the target internal temperature setting value by a predetermined amount, the predetermined pressure setting value is lowered by a certain predetermined amount. .
