被动式太阳能结合相变墙在苏北自然通风环境下的应用研究

通过建立实体的模型房间,选择寒冷的冬季和炎热的夏季两种环境,对被动式太阳能建筑结合相变墙体的综合应用状态进行了模拟研究,获得了太阳能集热墙、相变墙体等结构的表面温度及室内温度参数,利用动态热网络分析法,建立综合考虑建筑内部舒适度的4种运行工况,通过对比分析的方法,验证了由被动式太阳能建筑结合相变墙体的实验房具有冬暖夏凉的功能。在炎热的夏季,相变墙发挥了蓄冷作用,同时太阳能集热墙的被动通风,使得实验房内白天温度较普通房有所下降;在寒冷的冬季,白天太阳能集热墙的吸热与相变材料的蓄热,使得实验房内夜晚温度较普通房有所上升,从而实现实验房冬暖夏凉的功能。

The Application of Passive Solar Building Combined with Phase Change Wall Based on Natural Ventilation in Northern Jiangsu

In the productivity of the 21st century, the rapid development of economic globalization and the development of industrialization, the energy shortage and environmental pollution problems will follow. With the continuous consumption of conventional energy, solar energy development has become the important subject of the development of energy today. This paper analyzes the passive solar energy building energy saving technology, and USES the phase change materials to improve the collection of thermal heat storage wall make it suitable for jiangsu northern temperate zone monsoon climate area, in order to reduce air consumption, improve the indoor environment and comfort, so as to achieve the purpose of saving energy.
