dc.description.abstractIn 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 degrees 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 degrees C. The power used until the surface temperature of the heat storage layer reached 30 degrees 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 degrees 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.-
