为了克服常规热泵在低温下压比过大和效率降低的问题,提出了一种全新的低环温电驱动双作用行波热声热泵。对该新型热泵使用的多种回热器填充物进行了模拟优化计算,计算结果表明丝径小的回热器获得的系统最佳效率较高,但是丝径越小,获得最佳效率所对应的回热器孔隙率也越大,减小丝径能有效提升泵热量。计算结果为合理选择电驱动双作用行波热泵的回热器填充物提供了指导。 In order to overcome the problem that the conventional heat pump has a large pressure ratio at low temperature and a low efficiency, a new low-temperature dual-action traveling-wave thermoacoustic heat pump with low temperature is proposed. The simulation results show that the optimum system efficiency is obtained by the regenerator with small diameter, but the smaller the diameter is, the better the efficiency is obtained The regenerator porosity is also larger, reducing the wire diameter can effectively enhance the pump heat. The results provide guidance for the reasonable choice of regenerator packing for electrically driven dual acting traveling wave heat pump.
