摘要
对于对于低品位热能远距离输送这一新兴的研究领域做了研究现状综述。主要有五种方法可实现这一目标:可逆化学反应;蓄热材料;氢吸附合金;气-固吸附;气-液吸收。详述了每种方法的基本原理、研究进展、优缺点以及应用范围,总结比较得出了采用气-液吸收循?具有良好的应用前景。低品位热能远距离输送这一研究领域对于节能减排,能源的高效利用等方面具有重大意义。
The research on long distance transportation technology of low-grade heat is reviewed. It consists of reversible chemical reactions, phase change materials of thermal storage and transportation, hydrogen-adsorbing alloys, solid-gas adsorption, and liquidgas absorption. Their basic principles and research development are discussed, and the advantages and shortcomings are compared. The conclusion can be drawn that the liquid-gas absorption cycle may be prospective in application.
