Title:
STIRLING REFRIGERATOR
Document Type and Number:
Japanese Patent JP2019027600
Kind Code:
A
Abstract:
To improve energy efficiency.SOLUTION: A Stirling refrigerator has: a compression cylinder; a compression piston which forms a compression space with the compression cylinder and reciprocally moves in the compression cylinder; an expansion cylinder; an expansion piston which forms an expansion space communicating with the compression space via a radiator and a heat accumulator with the expansion cylinder and reciprocally moves in the expansion cylinder, interlocking with the reciprocal movement of the compression piston; and a driving part driving the compression piston and the expansion piston. There is provided at least one cold generating part which generates cold at a terminal on the expansion space side of the expansion cylinder on the basis of a pressure amplitude of working fluid in an actuating fluid space from the compression space to the expansion space. The Stirling refrigerator which cools an object to be cooled with the cold generated by at least one cold generating part is provided with a pressure amplitude adjustment part adjusting pressure amplitude of the working fluid in the actuating fluid space.SELECTED DRAWING: Figure 1
