Exhaust Ventilation through a Solar Chimney: A Response to High Hermeticity in Welfare Housing M.E. Gonzalez-Trevizo; Adolfo Gomez-Amador; Anibal Luna-Leon; Carlos Escobar-del Pozo; Carlos Javier Esparza Lopez This research reports on potentiality in the solar chimney as an exhaust ventilation device through a hypothetical statement that convenient weather conditions exist on sub-humid warm climate to enhance the performance of a SC (solar chimney), in order to increase ventilation to dissipate metabolic heat from inhabitants of airtight buildings.The methodology used in this research integrates the use of simplified mathematical models that predict in a semi-empirical way a potential volume flow through estimation of kinetic power generation, by natural circulation and stack effect in a typical covered-plate air solar collector.The study was carried out during the warm month of April, an important warm season for Colima, where the prevailing wind is about 6.8 m/s, the average temperature of maximums and minimums oscillates between 15.4 °C and 34.4 °C with average relative humidity of 65% according to national weather service.A scale model of the SC was installed on environmental chambers.The results showed that this device is capable of generating ventilation conditions around light breeze parameters near between 0.6 m/s and 1.5 m/s width, a better performance at day in 45% approximately than the night values, making ventilation rates up 0.24 ACH (air changes per hour) as average air change rate.

Abstract
This research reports on potentiality in the solar chimney as an exhaust ventilation device through a hypothetical statement that convenient weather conditions exist on sub-humid warm climate to enhance the performance of a SC (solar chimney), in order to increase ventilation to dissipate metabolic heat from inhabitants of airtight buildings.The methodology used in this research integrates the use of simplified mathematical models that predict in a semi-empirical way a potential volume flow through estimation of kinetic power generation, by natural circulation and stack effect in a typical covered-plate air solar collector.The study was carried out during the warm month of April, an important warm season for Colima, where the prevailing wind is about 6.8 m/s, the average temperature of maximums and minimums oscillates between 15.4 °C and 34.4 °C with average relative humidity of 65% according to national weather service.A scale model of the SC was installed on environmental chambers.The results showed that this device is capable of generating ventilation conditions around light breeze parameters near between 0.6 m/s and 1.5 m/s width, a better performance at day in 45% approximately than the night values, making ventilation rates up 0.24 ACH (air changes per hour) as average air change rate.
