随着科技的进步,各行各业得到了迅猛的发展,随之而来的节约能源和加强环境保护的主题也就被推到了时代需求的风口浪尖处。在暖通行业中,空气源热泵系统的应用越来越广泛,同时,也备受人们的关注。但在寒冷地区,空气源热泵的推广却受到很大的限制。国内暖通人士针对寒冷条件下产生的限制因素,提出了不同的解决方案。通过总结分析我国低温空气源热泵的技术发展现状、系统的除霜手段及新型制冷剂、混合型制冷剂的研究成果,为以后低温空气源热泵的发展和应用提供指导意义。
With the progress of science and technology, all walks of life have witnessed rapid development. The ensuing themes of energy conservation and environmental protection have also been pushed to the cusp of the needs of the times. In the HVAC industry, the application of air source heat pump system is more and more widely, at the same time, it also attracts people’s attention. However, in cold areas, the promotion of air source heat pump has been greatly restricted. Domestic HVAC people have put forward different solutions to the restrictive factors arising from the cold conditions. Through summarizing and analyzing the current situation of technology development of cryogenic air source heat pump in our country, the defrosting means of the system and the research results of new refrigerants and mixed refrigerants, which provide the instructional significance for the future development and application of cryogenic air source heat pump.
