AI Technical Summary
The existing JT throttling refrigeration system has problems such as low system integration and low energy utilization efficiency, and fails to effectively recover the expansion work of the regenerative refrigeration unit to drive the JT compressor.
The expansion piston of the regenerative refrigeration unit is coupled with the compression piston of the compression refrigeration unit. The expansion work of the regenerative refrigeration unit is converted into the power of the compression refrigeration unit through a phase-coordinated control system. Combined with the heat absorber, the refrigerant in the heat exchanger of the precooling section is precooled, thus realizing the integrated coupling of precooling and power supply.
It improves the energy utilization efficiency and integration of the refrigeration system, reduces the input of external energy, meets the requirements of ultra-low temperature refrigeration, and can operate stably for a long time in low temperature environments.
