特朗贝墙（T-Wall）因具有节约化石能源、改善室内环境等优点而被广泛应用于建筑中，但传统的T-Wall通常存在热效率低、热惯性大等缺点，导致夜间供暖性能差、能量损失大。为了克服上述缺点，本文设计了一种改进型T型墙，并对其加热性能进行了实验研究。首先对改进后的T型墙、测试台架和测量系统进行了详细的描述。给出了实验步骤、实验条件和数据处理方法。最后对实验结果进行了分析和讨论。结果表明，在超过一半的测试时间内，测试室内的空气温度高于16.0 ℃，通风口处的最小风速为0.35 m/s，可以使室内空气流通，改善热环境。此外，改进的T型墙的日热效率在白天高于50%。因此，本研究的结果为改善T型墙的加热性能提供了有价值的见解。(C)2018爱思唯尔有限公司版权所有。
A Trombe wall (T-Wall) is widely applied to buildings due to the advantage of saving fossil energy and improving indoor environment, etc. However, a traditional T-Wall usually has the drawbacks of low thermal efficiency and thermal inertia, which lead to poor heating performance and significant energy loss at night. To overcome the above drawbacks, in this paper, an improved T-Wall was designed and its heating performances were experimentally investigated. Firstly, a detailed description on the improved T-Wall, test-bench and measurement system were reported. Then, the experimental procedures, conditions and data reduction were given. Finally, the experimental results were analyzed and discussed. The results revealed that the air temperature in the test room was higher than 16.0 degrees C during more than half of the testing time, and the minimum air velocity was 0.35 m/s at the vent outlet, which could circulate the indoor air to improve the thermal environment. Furthermore, the daily thermal efficiency of the improved T-Wall was higher than 50% during the daytime. Therefore, the results of this study provided valuable insights for improving the heating performance of T-Wall. (C) 2018 Elsevier Ltd. All rights reserved.
