Abstract

A full Localization [email protected] helium cryogenic refrigerator, composed of a helium screw compressor and its oil-removal subsystem, six plate-fin cryogenic heat exchangers, two high speed turbine expanders, eight pneumatic valves and a vessel with heat load, was developed at TIPC. The high and low pressure can be maintained stable by adjusting the PI parameters of pneumatic valves. Commissioning full localization [email protected] refrigerator system is discussed. 300~4.5K cool-down processes of cryogenic heat exchangers are present. The optimized cooling capacity of this refrigerator system is up to 317W at liquid helium teperature.
