Pulse Tube Refrigeration with a Combined Cooling and Freezing Cycle for HTSC Devices
- 1.2k Downloads
Based on the analysis of a modified Brayton cycle, a combined cooling and freezing cycle is introduced for pulse tube refrigeration with a binary refrigerant. A novel configuration of a pulse tube refrigerator with a frozen cryogen accumulator is proposed as an example for possible applications. Some experimental phenomena explaining the working principles are presented.
