| 中文摘要: |
| 为解决空气源热泵在低温环境下供热量不足、压比大和结霜严重等问题，许多学者进行了理论和实验研究，提出了外加辅助热源、优化压缩机性能和自动除霜等解决方案。笔者总结了部分学者在太阳能空气源热泵、两级压缩与单级中间补气以及除霜技术方面的研究成果，同时介绍了热声热泵技术在低温下提升系统性能，展望了无霜热泵技术在抑制结霜方面的应用前景，以期为低温空气源热泵的继续研究和推广提供参考。 |
| 英文摘要: |
| In order to solve the problems of insufficient heat supply, large pressure ratio and severe frost in the low temperature environment. Many scholars carried out theoretical and experimental research, and proposed some solutions, such as auxiliary heat source, compressor performance optimization and automatic defrost. The author summarized some scholars′ research results in the solar air source heat pump, two stage compression with single stage compression system with intermediate vapor injection and defrosting technology, which could provide reference for further research and popularization of low temperature air source heat pump. At the same time the article introduced thermacoustic heat pump technology to improve system performance in low temperature, and the application prospect of frost free heat pump technology in the frost suppression. |
