摘　　要：将潜热型功能流体作为循环工质应用于太阳能供暖集热系统,并与传统水作为循环工质的太阳能供暖集热系统进行对比实验研究。在相同的实验条件下,对2种循环工质的太阳能供暖集热系统的日储热量、集热量和平均集热效率等进行实验研究和对比分析。研究表明:采用潜热型功能流体作为循环工质替代水,其日平均集热效率提高值达9%以上,提升率达20%以上,可明显提升太阳能供暖集热系统的集热效果。In this study,the LFTF(latent functional thermal fluid)is applied to solar heating system as the cycle fluid,and compared with the traditional solar heating system with water.The daily heat storage capacity,heat collection capacity and daily average heat collecting efficiency of the solar heating system with different cycle fluid are tested and analyzed under the same experimental conditions.The results show that compared with the traditional solar heating system,using latent functional fluid as circulating working fluid instead of water can significantly improve the heat collecting effect of solar heating system,its daily average thermal collecting efficiency is increased by more than 9%,and the improvement rate is over 20%.
