This article presents an experimental study of a Trombe wall made of cellular concrete, associated with different vent configurations. The experiments were conducted in the laboratory using a Trombe wall connected to an adjacent room, under conditions of an intermediate season. The measurements focus on temperature and heat flux measured in various areas of the facility. Five configurations are compared: one with the vents fully open, three with reduced vent surface areas and different positions, and one with the vents fully closed. The impact of the number and position of the vents on the thermal behavior and efficiency of the Trombe wall is measured and analyzed. The results indicate that only the configuration with the vents fully closed exhibits a very different thermal behavior compared to the other configurations. In this configuration, the insulating properties of cellular concrete result in a minimal temperature increase in the room, making it an appropriate solution for maintaining occupant comfort even during summer conditions. Configurations with partially closed vents show generally similar behavior, except when there are significant reductions in vent surface. To effectively limit convective transfer with partial vent closure, a substantial reduction in vent surface (at least 60%) is required.

通风口对 Trombe 墙热性能影响的实验研究


本文介绍了由蜂窝混凝土制成的 Trombe 墙的实验研究，该墙与不同的通风口配置相关联。实验是在实验室中使用连接到相邻房间的 Trombe 墙在中间季节的条件下进行的。测量的重点是在设施的各个区域测量的温度和热通量。比较了五种配置：一种是透气膜完全打开，三种是减少透气表面积和不同位置的配置，一种是透气膜完全关闭的配置。测量和分析了通风口的数量和位置对 Trombe 墙的热行为和效率的影响。结果表明，与其他配置相比，只有通风口完全关闭的配置才会表现出非常不同的热行为。在这种配置中，多孔混凝土的绝缘性能使房间内的温度升高最小，使其成为即使在夏季条件下也能保持居住者舒适度的合适解决方案。具有部分关闭的通风口的配置通常表现出类似的行为，除非通风口表面明显减少。为了在部分通风口关闭的情况下有效限制对流传输，需要大幅减少通风口表面（至少 60%）。
