Cryogenic refrigeration apparatus and method of controlling cryogenic refrigeration apparatus

摘要

A cryogenic refrigeration apparatus includes a compressor, a plurality of refrigerators, and a gas line configured to connect the plurality of refrigerators to the compressor in parallel so as to circulate a working gas between each of the plurality of refrigerators and the compressor. The gas line may include a flow rate control valve capable of individually controlling a pressure drop of a flow of working gas in a corresponding one of the plurality of refrigerators. The flow rate control valve may be provided in series with the corresponding refrigerator.
