摘要

提出一种太阳能热水相变蓄热炕的新型供暖系统，系统无须设置水箱，仅使用炕板与相变材料作为蓄热装置，可有效提高供暖效率。基于Fluent数值模拟平台，建立相变炕的二维非稳态传热模型，研究相变炕的蓄放热性能，并与混凝土炕的热性能进行对比；还分析了相变材料的相变温度和潜热对相变炕蓄放热性能的影响。结果表明，在设定工况下，与混凝土炕相比，上炕面的日间与夜间稳定温度分别提高2℃和4℃，上炕面最大温差由3.7℃降至0.8℃，全天得热量提高了66.36%。因此，相变炕具有上炕面温度较高、温度分布均匀、得热量大以及保温性能好等优点；提高相变温度，炕体得热量会有所减少，但对提升上炕面温度作用显著；增大相变潜热，可以显著提高炕体得热量，但对提升上炕面温度作用不明显。

Abstract

The system combining the solar water and phase change heat storage Kang is put forward. Instead of water tank

Kang plate and phase change material are used as heat storage devices to availably improve the heating efficiency in this system. Based on Fluent

two-dimensional unsteady heat transfer model of the Kang is established. The heat storage and release characteristics of phase change Kang is studied and compared with the thermal properties of concrete material Kang. The effects of phase change temperature and latent heat of phase change materials on the heat storage and release characteristic of Kang are also analyzed. Under the working condition of this article

the stable temperatures of the upper surface of Kang of day and night increase by 2℃ and 4℃

respectively. The largest surface temperature difference of Kang decreases from 3.7℃ to 0.8℃. The heat increased by 66.36%. The phase change heat storage Kang has the advantages of high temperature of the upper surface of Kang

uniform temperature distribution

good heat-insulation property and large heat storage capacity. Results show that the temperature of the upper surface of Kang at night increase significantly

with the increase of phase change temperature

but the heat gain of Kang is reduced. Increasing the latent heat has little effect on the temperature of the upper surface of Kang

while significant effect on the heat gain of the Kang.
