ABSTRACT

In this study, the temporal and spatial temperature distribution of the heat storage mortar made of porous feldspar was measured and the thermal properties and electricity consumption were analyzed. To compare the effects of porous feldspar mortar, two real-size models (control and test model) were constructed. The surface temperature change of the heat storage layer was remotely monitored during the heating and cooling process using an infrared thermal imaging camera and temperature sensor. The temperature of the heat storage layer of the test model was a maximum of 3.5°C higher than that of the control model and the target temperature was reached more quickly. As the distance from the hot water pipe increased, the temperature gap increased up to about 4.8°C. The power used until the surface temperature of the heat storage layer reached 30°C was 2.2 times that of the control model. From the heating experiment, the stepwise temperature and electricity consumption were calculated, and the electricity consumption of the heat storage layer of the test model calculated from this was largely reduced. In the cooling experiment, the surface temperature of the heat storage layer of the test model was maintained at higher than 2°C. The effect of the porous feldspar mortar on the heat storage was confirmed by these heating and cooling experiments. Therefore, the time to reheat the heat storage layer for thermal comfort is extended, and the energy efficiency will be increased.

摘要

本研究对多孔长石蓄热砂浆的时空温度分布进行了测量，并对热性能和电耗进行了分析。为了比较多孔长石砂浆的效果，构建了两个真实尺寸的模型（控制模型和测试模型）。利用红外热像仪和温度传感器远程监测加热和冷却过程中蓄热层的表面温度变化。试验模型蓄热层温度最高比对照模型高3.5℃，更快地达到目标温度。随着与热水管距离的增加，温差增加到约 4.8°C。蓄热层表面温度达到30℃前所用的功率是对照模型的2.2倍。从供暖实验中，逐步计算出温度和耗电量，由此计算出的试验模型蓄热层的耗电量大大降低。在降温实验中，试验模型蓄热层表面温度保持在2℃以上。这些加热和冷却实验证实了多孔长石砂浆对蓄热的影响。因此，延长了蓄热层再加热热舒适的时间，提高了能源效率。由此计算得出的试验模型蓄热层的耗电量大大降低。在降温实验中，试验模型蓄热层表面温度保持在2℃以上。这些加热和冷却实验证实了多孔长石砂浆对蓄热的影响。因此，延长了蓄热层再加热热舒适的时间，提高了能源效率。由此计算得出的试验模型蓄热层的耗电量大大降低。在降温实验中，试验模型蓄热层表面温度保持在2℃以上。这些加热和冷却实验证实了多孔长石砂浆对蓄热的影响。因此，延长了蓄热层再加热热舒适的时间，提高了能源效率。
