Thermal comfort and energy analysis in ceramic tile

This study investigated the thermal touch comfort of ceramic tiles. The surface temperature was calculated by calculating the heat transfer at the time of contact. It is explained how the thermal inertia phenomenon contributes to the calculation of the surface temperature, and ceramic tiles feel cold when touched. To examine tactile comfort, the structure of the human skin and the mechanism of sensing the temperature are shown. In addition, the surface temperatures during touch were calculated and compared for other coating materials at the same temperature as the ceramic tile. The applicability of the coating option and how close it is to the goal of increasing thermal comfort are discussed. Thus, by calculating how much the coated ceramic tile improves thermal comfort, an essential study has been put forward to evaluate the thermal comfort improvements made on many surfaces used as coating elements in buildings and touched by people. It was calculated that the thermal inertia could increase by 4% with a 0.25 mm thin coating, and the prototype for this experiment was built. The calculated touch temperature of the coated ceramic tile increased by 0.2 degrees C compared to the uncoated tile. 2024 Sharif University of Technology. All rights reserved.
