しめたことを特徴とする炭酸ガス冷却制御装置。 The carbon dioxide gas supplied through the input pipe is distributed to a plurality of branch pipes each having a cooling heat exchanger for cooling, and then merges into the output pipe to be guided to the compressor. In the carbon dioxide gas cooling control device, the master signal of the pressure regulator is supplied as a cascade setting value to the flow rate controller of each branch pipe via a ratio setting device so that the pressure of the output pipe is constant, and the temperature of the output pipe is measured. While inputting the value, one specific bias value of each of the ratio setters is sequentially changed by a fixed amount, and the bias values of the other ratio setters are changed proportionally in the opposite direction to cancel out the above fixed amount change. . A carbon dioxide gas cooling control device comprising an optimum ratio setting changing device that cyclically performs a changing operation of reversing the polarity of the change if the measured temperature value does not change to a lower value.
