Document Type and Number:
Japanese Patent JP6526530
Kind Code:
B2
Abstract:
According to one embodiment, there is provided a refrigeration system including detectors, each of which detects a phase indicative of a displacement of a displacer of each of cryogenic refrigerators; a processor that calculates an operation frequency of a motor of each of the cryogenic refrigerators, which is a frequency that suppresses oscillations or noises generated by reciprocating motions of the displacer of each of the cryogenic refrigerators, based on a detection result obtained by each of the detectors; and drivers, each of which drives the motor of each of the cryogenic refrigerators based on a calculation result obtained by the processor.
