Desempeño térmico de un espacio habitable con ventilación modo mixto. Diferentes condiciones volumétricas y diferentes condiciones térmico ambientales en el Estado de Guanajuato. México

Abstract

In the present work the thermal performance of a habitable space with mixed mode ventilation is shown. Space located in a dwelling representative of the housing register by type and surface, data from CONAVI (2017). Results of operating temperature for a base case and six virtual evaluation models (MEVi) are presented, varying the interior air volume, using Design Builder® calculation tool. The main objective was to determine the model with less use of active systems by varying the volume of indoor air with a certain comfort range, according to each thermal condition, when using mixed mode ventilation. Key results: A) Heating and cooling needs were determined in three thermal conditions, B) by increasing the volume of indoor air, there was a decrease in comfort hours per year, and a clear tendency to keep the window open for three thermal conditions, C) it is demonstrated that, in the thermal conditions: cold sub humid, warm sub humid and temperate sub humid, that occur in the state of Guanajuato Mexico, the volume of indoor air is directly proportional to the energy demand by year.
