石蜡蓄热太阳能炕在北方农村住宅中的应用

本文针对北方农村地区的生活习惯设计了一套采用石蜡蓄热的太阳能采暖炕系统,不仅很好的利用太阳能这种清洁能源解决了炕的采暖问题,还可以在夏季提供部分生活热水。该太阳能炕系统中封装的石蜡由于其良好相变特性和较高的相变潜热,冬季供暖时段白天可在太阳能炕中续存一定的热量,晚上利用相变潜热释放的热量有效保证炕面温度,达到节能和提高舒适性的目的。对实际搭建的太阳能炕系统进行四个连续周期的测量表明,太阳辐照良好的情况下太阳能炕面平均温度可保证30~40℃的人体舒适性温度,具有很好的实际使用价值。

Application of Solar Energy Kang with Paraffin Wax Storagein Northern Rural Housing

A set of solar heating Kang system with paraffin heat storage is designed for the living habits of the northern rural areas.It not only solves the heating problem of Kang,but also provides hot water for living in summer.In the packaging of the solar Kang system due to its good paraffin latent heat of phase transformation characteristics and high in the daytime,solar Kang renew a certain amount of heat in the evening,with a latent heat releasing heat effectively ensure the Kang surface temperature,save energy and improve the comfort of the objective.The measurement of four continuous cycles of the solar Kang system built in this paper shows that the average temperature of the solar Kang surface can guarantee the comfort temperature of the human body at 30~40℃ under the condition of good sunshine,and it is of good practical use value.
