Abstract In ultra-low air temperature environment, conventional heat pumps have several technical
problems, such as high pressure ratio and low efficiency. To e the problems, a novel linear
compressor driven double-acting traveling-wave thermoacoustic heat pump is studied in the paper.
Through simulation and optimization, the influence of three kinds of regenerator fillers on the heat
pump thermodynamic performance is revealed. The results show that a smaller wire diameter
of the regenerator filler with higher porosity can lead to a higher thermodynamic e
