Popis: Nowadays, it is common to find heat transfer systems inside buildings. In the present work, a heat transfer system applied to a structural element of a building is proposed, which is produced with a system embedded inside the wall from the internal transport of the liquid that allows increasing or decreasing the interior temperature. For this, a mathematical model developed from a steady-state, one-dimensional energy balance was analytically solved. The system was applied in a circadian way with the data applicable to maximum and minimum temperatures in the city of Monterrey, Nuevo Leon. Experimentally, the thermal properties of the proposed material were obtained and a wall section was developed with the heat transfer system. An increase in thermal resistance is obtained that allows reducing the temperature changes on the interior face of the wall. The structural element presents thermal resistance values that increase while maintaining the fluid inside the wall. The system justifies the use of fluid within the vertical element that can promote comfort. Using this system would reduce energy consumption by up to 60% compared to a traditional cooling system. The objective of this work was to obtain a mathematical model that approximately describes the behavior of the interior temperature of the wall as a function of the exterior temperature and the flow and temperature of the cooling water, to evaluate the energy efficiency of the heat exchanger.
