热管置入式墙体冬季测试与分析

Measurement and Analysis on the Wall Implanted with Heat Pipes in Winter

热管置入式墙体是一种新型被动式太阳能利用技术.通过实际环境下的实验测试,对热管置入式墙体(WIHP)冬季的传热特性和室内热环境改善情况进行了探究.结果表明:WIHP的应用使南向墙体内表面平均温度提高,墙体蓄热能力增加;改善了室内温度的分布;降低了冬季的供暖热负荷,在室温维持在18℃的情况下,WIHP比非WIHP累计减少热损失1.79 kW·h/m^(2),热管存在累计减少热损失6.1 kW·h/m^(2).

The wall implanted with heat pipes(WIHP)is a new passive solar energy utilization technology.In this paper,the heat transfer characteristics and indoor thermal environment improvement of WIHP were investigated in winter in a real environment.The results show that the application of WIHP increases the average temperature of the inner surface of the south-facing wall and the heat storage capacity of the wall.It also improves the distribution of indoor temperature and reduces the heating heat load in winter.When the room temperature maintains at 18℃,WIHP cumulatively reduces heat loss by 1.79 kWh/m^(2) compared with non-WIHP,and the heat pipes presence reduces heat loss by 6.1 kWh/m^(2) cumulatively.
