摘要
地球上化石能源的储量是有限的,而人类发展对能源的需求是无限的。探索可再生能源的利用方法和提高现有能源的利用效率,是解决人类发展过程中能源和环境两个根本问题的主要途径。由于黑色沥青路面具有很强的吸收太阳能的能力,利用沥青路面吸收太阳能成为了一项新型的能源利用技术。基于我国在能源需求和沥青路面的养护技术等方面的现状,归纳了沥青路面太阳能集热技术的研究和应用进展,从理论和试验两个方面总结了沥青路面太阳能集热规律。指出了今后的研究工作主要集中在数值及试验研究太阳能的转换、沥青路面集热器的优化和能量的跨季节存储等方面。
The normal fossil energy on earth is limited although the demand of energy for human development is never-ending.Searching for renewable energy and improving utility efficiency of energy are the main approach for the energy and the environmental issues for development of mankind.Asphalt solar collectors are becoming a new way of harnessing solar energy due to its excellent heating absorption property.Based on the situation of energy demand and asphalt pavement maintenance in China,the development of research and application of asphalt pavement solar collector was summarized and the rules of collecting solar energy accumulated in asphalt pavement from theoretics and experimentations were reviewed. It is pointed out that the researches of asphalt collector technology in the future are focused on solar energy transfer,optimization of asphalt collector and inter-seasonal storage of solar energy by numerical and experimental approaches.
