摘要
碳中和目标的提出以及人们对居住环境舒适度要求的持续提升,都对空调系统提出了更高的要求.直接空气碳捕集(DAC)技术能够从分布式的稀薄碳源中捕获二氧化碳,与建筑空调通风系统具有很好的技术匹配性.近年来,形成了DAC与空调系统集成的技术路线.该研究从技术层面总结了该技术路线的研究进展,并对该技术的发展趋势及面临的挑战进行了评述.研究结果表明,DAC技术能够在碳减排、室内空气质量控制和节能提效等方面推动空调技术的高效、低碳和健康立体化发展.然而,现阶段DAC与空调通风系统集成技术仍处于起步阶段,面临技术、成本、安全、政策等多方面挑战,亟需在相关方向展开深入研究.
Abstract
The proposal of carbon neutrality goals,as well as the ongoing enhancement of people's needs for comfort in their living environment,have led to increasing air-condi-tioning system.Direct air capture (DAC)technology is capable of capturing CO2 from a distributed rarefied carbon source,making it a good technical fit for building air-condition-ing and ventilation systems.In recent years,a technical path for integrating DAC and air-conditioning system has been proposed.This study reviews the research progress of this technology route from the technical perspective,as well as the development trend and challenges of this technology.Results show that DAC technology may promote the effi-cient,low-carbon and healthy development of air-conditioning technology by reducing car-bon emissions,increasing indoor air quality,conserving energy and improving effici-ency.However,at this moment,the integration technology of DAC and air-conditioning and ventilation systems is still in its infancy,and it confronts several challenges such as technology,cost,safety,and policy,making it urgent to carry out in-depth research in related areas.
