摘　　要：有效利用太阳能、空气能等可再生能源是降低建筑运行碳排放的重要技术途径。随着人们对室内热舒适度要求的提高,夏热冬暖地区在冬季部分时间的采暖需求也日益迫切。基于此,针对广州市某建筑房间在冬季部分时间的采暖需求,将其作为供暖对象,搭建了太阳能-空气源地暖系统,对该系统的供暖性能进行了研究。通过实验测试了供暖房间的空气温度、供热量等参数,并计算了太阳能利用率、空气热能利用率、可再生能源利用率、太阳能贡献率等评价指标。研究结果表明:在实验测试工况下,室外平均空气温度为6.3℃时,太阳能-空气源地暖系统可提供55℃热水,将供暖房间的日平均空气温度维持在约18.9℃,可满足相关标准中关于冬季供暖房间空气温度的要求。测试期间,太阳能-空气源地暖系统的可再生能源利用率平均值为48.2%,太阳能贡献率为11.4%。数据表明,太阳能-空气源地暖系统在满足了夏热冬暖地区冬季部分时间采暖需求的同时,有效利用了可再生能源,减少了电能消耗和碳排放。研究结果可为可再生能源供暖系统的设计和性能评估提供数据参考。Effectively utilizing renewable energy sources such as solar energy and air energy is an important technological approach to reducing carbon emissions from building operations.With the increasing demand for indoor thermal comfort,the heating demand in hot summer and warm winter area is becoming increasingly urgent during some parts of the winter.Based on this,this paper focuses on the heating demand of a building room in Guangzhou during some parts of the winter,and takes it as the heating object to build a solar-air source underfloor heating system,and the heating performance of this system is studied.The air temperature and heating capacity of the heating room are tested through experiments,and evaluation indicators such as solar energy utilization rate,air thermal energy utilization rate,renewable energy utilization rate,and solar energy contribution rate are calculated.The research results show that under testing conditions,when the outdoor average air temperature is 6.3℃,the solar-air source underfloor heating system can provide hot water of 55℃,and maintain the daily average air temperature of the heating room at about 18.9℃,which can meet the requirements of relevant standards for air temperature in winter heating rooms.During the testing period,the average renewable energy utilization rate of the solar-air source underfloor heating system is 48.2%,and the solar energy contribution rate is 11.4%.The data shows that the solar-air source underfloor heating system not only meets the heating demand of hot summer and warm winter area,but also effectively utilizes renewable energy,reducing electricity consumption and carbon emissions.The research results can provide data reference for the design and performance evaluation of renewable energy heating systems.
