Document Type and Number:
Japanese Patent JP7436980
Kind Code:
B2
Abstract:
Problem - To provide a liquefaction apparatus which automatically adjusts the load on the liquefaction apparatus correspondingly with an upper limit value of contracted power in different time slots, and which is capable of maximizing the amount of liquefied product produced and of achieving optimum operating efficiency.Solution - A liquefaction apparatus 1 comprises: a production amount calculation unit 91 for obtaining an actual production amount of a liquefied product; a predicted power calculation unit 92 for obtaining a predicted power amount after a predetermined time (e.g., 10-40 minutes) has elapsed, on the basis of an integrated power value obtained by integrating a usage power; anda power demand control unit 93 for comparing the predicted power amount and a moving average of instantaneous power, and controlling a discharge flow rate of a compressor 3 in such a way as to come infinitely close to a target value, without exceeding the target value, and while using the larger value of the predicted power amount and the moving average of instantaneous power as a value being controlled.
