| 摘 要： | 在传统空气源热泵(ASHP)机组上耦合空气除湿设备,实现其无霜连续高效稳定运行,有利于ASHP在低温高湿度地区清洁供暖中的推广应用。在对三类结霜过程进行分析的基础上,总结了各种无霜ASHP技术原理,并将其分为三大类:固体除湿型无霜技术、液体除湿型无霜技术和其他无霜技术。重点概括了固体和液体除湿型无霜ASHP技术的研究现状。指出了各种无霜技术存在的问题及局限性并给出了推荐研究和不同环境条件下的发展优先级,提出今后应主导做好影响无霜热泵系统投资成本和运行性能相关的各方面研究,进而开发性能良好且地域限制较小的多功能无霜ASHP技术。

| Abstract: | Coupling the air dehumidification equipment on the traditional air source heat pump (ASHP) unit to achieve its frost-free continuous high-efficiency and stable operation is conducive to the popularization and application of ASHP in clean heating in low temperature and high humidity areas. Hence, based on the analyses of three types of frosting processes, the principles of various frost-free ASHP technologies were summarized and divided into three categories in the present paper as follows: frost-free ASHP technology with integrated solid desiccant dehumidification, frost-free ASHP technology coupling with liquid desiccant dehumidification, other frost-free ASHP technologies. Then the research status of the first two frost-free ASHP technologies was reviewed, respectively. Finally, the problems and limitations of these frost-free technologies were pointed out, and the research recommendations of various methods and their development priorities under different environmental conditions were given, respectively. Meanwhile, it was suggested that all aspects of researches affecting the investment cost and operation performance of frost free heat pump system should be mainly carried out, and thereby develop the multi-functional frost free ASHP technology with high performance and small regional restrictions in the future. |
