本文报道了太阳池中物理热过程及池底相变材料相变热过程的数学模型,并利用计算机对长期运行的潜热太阳池池底温度变化情况进行了模拟,探讨了将水合盐类相变材料应用于太阳池中以提高太阳池蓄热能力的可能性。计算结果表明,在现有的技术经济条件下,利用水合盐类相变材料来提高太阳池的蓄热能力效果不大。
This paper reports the mathematical model of the physical thermal process in the solar pool and the phase change thermal process of the pool bottom phase change material, and simulates the temperature change of the bottom pool of the long-run latent solar pool using a computer. Material used in the solar pool in order to improve the solar pool thermal storage possibilities. The calculation results show that under the existing technical and economic conditions, the use of hydrated salt phase change materials to improve the solar thermal storage capacity is not effective.
