Dynamic thermal performance of prefabricated temporary exterior wall using cooling water in the cooling season

The acceleration of urbanization has led to a continuous increase in various types of buildings. In the hot season, cooling systems cool buildings and improve their comfort. However, traditional cooling methods require more energy consumption and greenhouse gas emissions. This paper designs a prefabricated building exterior wall with embedded pipes based on water cooling system reduces the output of traditional cooling way in building cooling. The innovation of this research is using the embedded pipe to improve the thermal properties of exterior walls, bonging the embedded pipe and exterior wall structure together. The results show that the embedded prefabricated building exterior walls are designed to control the indoor wall temperature to around 28 ℃ in summer. And the temperature on the surface of the inner liner cavity is always above 25.5 ℃. The overall trend shows a decrease followed by an increase. At noon, the surface temperature on the cavity side of the inner lining plate is the lowest, about 25.8 ℃. The larger the indoor and outdoor temperature difference, the better the cooling effect of the structure on the building. This study's application can help reduce energy consumption and carbon emissions effectively.
