Estudio del confort térmico mediante simulación validada de una edificación tipo con material de cambio de fase en la envolvente en varias zonas climáticas del Ecuador

Abstract

Nowadays, the building sector aims to improve the thermal comfort and reduce the energy consumption implementing new alternative systems. For this purpose, a new phase change material (PCM) is being studied to analyze performance of a building in three different climates of Ecuador by using a simulation tool. This work assesses performance of the use of PCM through a virtual model in Design Builder. To improve reliability of simulation results, model is calibrated with experimental previous existing data of a building, which is a monitoring room without occupancy already studied (original model) in Monterrey. The PCM is located in the roof and walls of the virtual calibrated model. The prime matter of PCM is found in Ecuador and its thermal and chemical characteristics were evaluated a previous study. This study assesses thermal comfort by using the predicted mean vote (PMV). The original model and PCM results are compared by the total time of thermal comfort during a year in three Ecuadorian cities. The main found conclusions includes that the use of a PCM into a building located in Quito increase the thermal comfort time, since the PMC reduces the air temperature fluctuation. However, the use of PCM in Zumbahua represents a disadvantage because the climate conditions do not allow storing energy in the PCM as latent heat. In Guayaquil, the performance of the PCM could be improved by using air conditioned systems, reaching both, change phase
