为了更好地开发并储存太阳能,将其用于冬季供暖。利用石蜡这一相变材料,白天充分吸收太阳能并给水加热,当夜间水的热量无法满足供暖需求时,由石蜡储存的热量给水加热。结果表明:通过石蜡相变材料与太阳能的耦合作用,实现了太阳能的高效利用,相变材料作为供暖方案中的导热介质,在清洁供暖体系中有一定现实意义。能够加快复合型相变材料应用于供暖系统中,提高严寒地区冬季供暖的效果。石蜡相变材料与太阳能的有效互补,实现了节能减排的重要目标,探索出了严寒地区清洁能源供暖的新方案。

To better develop and store solar energy, and use it for winter heating. The paraffin material be used, which is a phase change material, to fully absorb the solar energy and heat the water during the day. When the water heated at night cannot meet the heating demand, the heat stored by the paraffin water warms the water. The results show that: Through the coupling effect of paraffin phase change material and solar energy, the efficient utilization of solar energy is realized, showing the practical significance of the phase change material as the heating conduction medium in the clean heating system. It can accelerate the application of compound phase change materials in the heating system and improve the effect of winter heating in cold areas. The effective complementarity of paraffin phase change materials and solar energy has achieved the important goal of energy conservation and emission reduction, and explores a new scheme of clean energy heating in cold areas.
