将相变蓄能和毛细管网型太阳能采暖两种技术同时运用于火炕供暖上,通过实验研究相变蓄能材料和太阳能毛细管网低温热水联合辅助供暖时对室内温度和舒适性的影响,得出普通房间炕头、炕中、炕尾的平均温度分别为65.70、43.28、39.82℃,温差大于20℃,而采用该系统的房间炕头、炕中、炕尾的平均温度分别为40.96、39.06、37.52℃,温差最大仅为3℃;夜间炕面温度下降阶段,铺有相变材料的炕面温度下降缓慢,在00:00~07:00之间均高于普通火炕炕面温度,优势明显。新模式下的房间白天室内平均温度比普通房间高14.31℃,夜间比普通房间高7.21℃,可改善农居室内及炕面的热舒适性。
The phase change energy storage and capillary network type solar heating are applied to heating kang heating at the same time. The effects of phase change energy storage materials and solar capillary network combined with auxiliary heating on indoor temperature and comfort are obtained through experiments The average temperature of the kangtou, kang and kang tail in the common room was 65.70, 43.28 and 39.82 ℃ respectively, and the temperature difference was more than 20 ℃. The average temperature of the kangtou, kang and kang tail in the room with this system were respectively 40.96, 39.06 and 37.52 ℃, the maximum temperature difference is only 3 ℃. At night, when the temperature of kang surface decreases, the temperature of kang surface covered with phase change material slows down. It is obviously higher than that of ordinary kang kang surface between 00: 00 ~ 07: 00. Under the new mode, the indoor average temperature of the room during the day is 14.31 ℃ higher than that of the ordinary room and 7.21 ℃ higher than that of the ordinary room at night, which can improve the thermal comfort of the indoor living room and the kang noodles.
