摘要： PROBLEM TO BE SOLVED: To provide a driving method for a two-stage pulse tube refrigerator capable of providing high efficiency by a small capacity compressor.
SOLUTION: In this two-stage pulse tube refrigerator, a fist stage side pulse tube refrigerator (1) and a second stage side pulse tube refrigerator (2) are arranged parallel with each other. A first stage side cold accumulator (3) and a second stage side cold accumulator (4) are communicably connected to a shared compressor unit (5) through a flow passage changeover valve (6). When the flow passage changeover valve (6) is connected to either of the first stage side cold accumulator (3) and the second stage side cold accumulator (4) in the high-pressure flow passage (15) of the compressor unit (5), a high-pressure gas from the compressor unit (5) is selectively supplied to the first stage side cold accumulator (3) or the second stage side cold accumulator (4) by controlling the flow passage changeover valve so that the low-pressure flow passage (16) of the compressor unit (5) can be connected to the other sides of the first stage side cold accumulator (3) and the second stage side cold accumulator (4).

摘要： PROBLEM TO BE SOLVED: To provide an impulse wave tube refrigerator with high refrigeration efficiency realizing a more lower achievable temperature.
SOLUTION: The impulse wave tube refrigerator with a plurality of refrigeration parts 100 and 200 (combinations of cold storage units and impulse wave tubes) connected serially is characterized in that the rear refrigeration part 200 is precooled by the front refrigeration part 100. In a serial type impulse wave tube refrigerator, expansion work of the impulse tube in the refrigeration part 100 can be recovered as compression work by a refrigerator 200. Accordingly, work loss in the refrigeration part 100 does not theoretically exist. A multistage type cold storage unit 21 with two or more cold storage members 213 and 216 connected serially is adopted as the cold storage unit for the refrigeration part 200, and by precooling a connection portion 214 of the cold storage members 213 and 216 of the multistage type cold storage unit 21, and a low temperature end 122 of the refrigeration part 100 by a heat transfer member 215, expansion work in the refrigeration part 200 adopting the multistage type cold storage unit can be minimized so that it is not worth recovering, and refrigeration efficiency is improved.

摘要： A method and system for providing a ride-through reserve for a pulse tube refrigerator (PTR) (12) includes a pressurized tank (42) containing a fluid used to provide fluid pressure and auxiliary power to a PTR (12) during an electrical power supply failure. A pressure regulation valve (pressure valve) (44) releases the fluid from the pressurized tank (42) into the PTR (12). A power regulation valve (power valve) releases from the pressurized tank (12) a driving gas volume for driving a pneumatic motor (46). The pneumatic motor (46) in turn drives a rotary valve (22) of the PTR (12). A release valve (50) releases fluid from the PTR (12) so as to lower the fluid pressure to a predetermined pressure range and enable fluid oscillation in the PTR (12).
