摘要/Abstract

摘要： 结合北方传统火炕的特点，建立了与太阳能热水系统结合的太阳能炕理论模型，并搭建太阳能炕系统实验台，进行了实验测试，模拟计算结果与实验测试结果吻合较好.依据通过实验验证的模型，采用合肥实测的气象数据，分析了太阳能炕系统在冬天工作时对睡眠热舒适度和室内热环境的影响.结果显示：在室外平均温度0 ℃左右和炕面温度不超过35 ℃的条件下，室内空气温度维持在8~15 ℃之间，在晚上21点太阳能热水系统对炕停止加热后，人所处的睡眠环境能保持在285~34 ℃的热舒适温度区间，太阳能贡献率为345%.

Abstract: According to the traditional fire KANG characteristics, a solar heating system named solar KANG was proposed and a theoretical study of solar KANG system was presented. Experiments of the solar KANG system were conducted and experimental tests were performed. The theoretical results are in good agreement with the experiment results. Based on the validated model and real time meteorological data of Hefei, thermal comfort in sleeping environments and indoor thermal environments were studied when the solar KANG system was in operation in winter. Results show that indoor air temperature varies between 8 ℃ to 15 ℃ when outdoor temperature is about 0 ℃ and KANG surface temperature is no more than 35 ℃. After stopping heating at 21 oclock at night, sleeping environments can be kept at the comfortable range of 28.5 ℃ to 34 ℃ with thermal energy stored in KANG releasing gradually. Solar contribution rate is about 345%.
