为了降低热带地区建筑物的能耗，本文研究了一种替代的建筑放热方式。地下土壤被认为是通过导热管从建筑物中提取热量的来源。导热管被认为是固定在墙壁的内表面上，其下部插入温度低于室内温度的地面。整个分析都是使用ANSYS 11进行的。研究了两个系统之间的热流，并对导热管的性能进行了检验。研究了室内温度下存在导热管以及机械冷却系统等被动式建筑节能技术。地下土壤被证明是一个热沉，并吸收从房间释放的热量和导热管将发挥作用，从房间的热量传递到地下土壤。当与其他机械或被动冷却系统一起使用时，该系统可以有效地工作。通过这种方式，节能措施可以使建筑物温度降低约3？。
In this paper, an alternative way of releasing heat of building is investigated in order to reduce energy demand of building built in tropical environment. Underground soil is considered as a source for extracting heat from building through thermal conductivity pipes. Thermal conductivity pipes are considered to be fixed on the inner faces of the walls and their lower part to be inserted to the ground where temperature is lower than the indoor temperature. The entire analyses were done numerically using ANSYS 11. Heat flow between two systems was studied and the performance of the thermal conductivity pipes was examined. The room temperature in the presence of thermal conductivity pipes as well as mechanical cooling system and other passive energy-efficient techniques of building were also studied. The underground soil was demonstrated to act as a heat sink and absorb heat released from the rooms and the thermal conductivity pipes would play a role in transferring heat from the rooms to the underground soil. The system works efficiently when it is used with other mechanical or passive cooling systems. In this way, energy saving measure could be possible to reduce building temperatures by around 3?.
