Abstract

In this paper, the research progress of frost-free air source heat pump (FFASHP) technology with integrated solid desiccant dehumidification is systematically reviewed in terms of technical principle, desiccant materials, desiccant-coated heat exchangers (DCHEs) and FFASHP system characteristics. The energy, economic and environmental benefits of the existing FFASHP systems are evaluated and compared with traditional reverse-cycle defrosting air source heat pump (ASHP) systems. These systems have numerous unresolved issues and challenges that impede their large-scale application. The future research direction is proposed in five aspects: new materials and novel structures, system optimization, performance evaluation, advanced models and standards, as well as control strategy optimization. FFASHP technology needs to introduce external heat sources (such as solar radiation heat, system waste energy and industrial waste heat) as the main energy of the desiccant regenerator and heat storage device (HSD) in accordance with regional climate characteristics. In addition, a new generation of FFASHP technology integrating heat storage and dehumidification should be developed for different climate regions, and a reasonable and scientific system performance evaluation method should be planned. This review is expected to provide some ideas for the innovation and industrialization of FFASHP technology.

集成固体干燥剂除湿的无霜空气源热泵技术的研究进展、挑战与展望

本文从技术原理、干燥剂材料、干燥剂包覆换热器（DCHEs）和FFASHP系统特点等方面系统综述了固体干燥剂集成的无霜空气源热泵（FFASHP）技术的研究进展。对现有FFASHP系统的能源效益、经济效益和环境效益进行了评价，并与传统逆循环除霜空气源热泵系统进行了比较。这些系统有许多未解决的问题和挑战，阻碍了它们的大规模应用。提出了未来的研究方向：新材料与新结构、系统优化、性能评价、先进模型与标准、控制策略优化五个方面。FFASHP技术需要根据区域气候特点，引入外部热源（如太阳辐射热、系统废能和工业废热）作为干燥剂蓄热装置（HSD）的主要能量。此外，应针对不同气候区域开发集蓄热除湿为一体的新一代FFASHP技术，并规划合理、科学的系统性能评价方法。本文的研究成果有望为FFASHP技术的创新和产业化提供一些思路。

期刊介绍： The mission of Renewable and Sustainable Energy Reviews is to disseminate the most compelling and pertinent critical insights in renewable and sustainable energy, fostering collaboration among the research community, private sector, and policy and decision makers. The journal aims to exchange challenges, solutions, innovative concepts, and technologies, contributing to sustainable development, the transition to a low-carbon future, and the attainment of emissions targets outlined by the United Nations Framework Convention on Climate Change. Renewable and Sustainable Energy Reviews publishes a diverse range of content, including review papers, original research, case studies, and analyses of new technologies, all featuring a substantial review component such as critique, comparison, or analysis. Introducing a distinctive paper type, Expert Insights, the journal presents commissioned mini-reviews authored by field leaders, addressing topics of significant interest. Case studies undergo consideration only if they showcase the work's applicability to other regions or contribute valuable insights to the broader field of renewable and sustainable energy. Notably, a bibliographic or literature review lacking critical analysis is deemed unsuitable for publication.
