摘要:
设计了一种以相变材料石蜡与混凝土相结合相变蓄能炕采暖系统，并将其与传统火炕、纯混凝土炕和纯石蜡炕进行了对比分析.在供热温度35 ℃、供热流量0.95 L/min实验条件下，测试了系统炕面温度、石蜡温度、进出口温度和炕面热流密度等参数.实验结果表明：石蜡混凝土炕面温度分布均匀，其炕头、炕中和炕尾温度无明显差异，供热效果与纯石蜡炕相近，且系统初投资比纯石蜡炕节省了30%.石蜡混凝土炕面平均温度为33.29 ℃，比传统火炕高10 ℃，炕面降温速率却仅为传统火炕的15%.与纯混凝土炕相比，由于结构不同，石蜡混凝土炕体在炕面平均温度、夜间温度下降速率、炕面热流密度和供回水温差特性上均优于纯混凝土炕
Abstract:
The phase change storage kang heating system is designed by using phase change material composited by paraffin and concrete (Paraffin-concrete), and comparisons have been made of the new heating system with the traditional kang, pure concrete kang and pure paraffin kang. At the set temperature of 35 ℃ and the flow rate of 0.95 L/min, the temperature of each monitoring point is measured. The results show that the paraffin-concrete kang surface temperature is evenly distributed, heating effect is remarkable same as pure paraffin kang, and 30% initial investment can be saved compared with the pure paraffin kang. Paraffin-concrete kang surface average temperature can reached 33.29 ℃, 10 ℃ higher than the traditional kang, paraffin-concrete kang surface cooling rate is only 15% compared with traditional kang. For the characteristics of kang surface temperature, temperature cooling rate in the night, kang surface thermal flux and temperature difference between supply and back-water pipes, the paraffin-concrete kang is better than the pure concrete kang due to the different structures.
