SPLIT TYPE STIRLING REFRIGERATING MACHINE AND DESIGN THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a method for easily designing a split type Stirling refrigerating machine in which difference is suppressed between driving frequency eigen frequency of a compression piston.;SOLUTION: The split type Stirling refrigerating machine is designed to satisfy a relationship; eigen frequency before encapsulating gas = driving frequency-pressure coefficient x encapsulated gas pressure, among the eigen frequency (Hz) before encapsulating gas dependent on the weight of a compression piston 23 and the spring constant of a piston control spring 24, driving frequency (Hz) of a compressor 11, gas pressure (kgf/cm2) of refrigerant gas encapsulated in the compressor 11 (split type Stirling refrigerating machine), and the pressure coefficient having value of 1.4-1.8 (Hz/(kgf/cm2)).;COPYRIGHT: (C)2000,JPO
