  1. 153. C1Or2A-01: Modelling and optimization of cryogenic mixed-refrigerant cycles for the cooling of superconducting power cables

    For the green energy transition, the transport of large amounts of electrical energy is needed both in densely populated areas and over long distances. Superconducting power cables represent one possible solution, requiring energy-efficient liquid nitrogen re-cooling stations for an economical operation at cable lengths longer than about 1 km to 2 km.

    The Brayton Circulating Cooling System is a unique refrigeration system developed as a technology demonstration for providing cold helium gas refrigeration at high pressures to an external superconducting magnet or any remote load for cool down purposes. The system is designed to provide cool down refrigeration from room temperature to target minimum temperatures of approximately 40K.

    Contributed Oral

    Cryogenic expanders are complex and expensive components in recuperative-cycle cryocoolers. To simplify cryogenic expander technology, we propose a novel acoustic expander. The acoustic expander utilizes sound waves in the expansion process without the need for complex moving parts at low-temperature; in contrast to turbine or piston expanders that require spinning shafts or moving displacers...
