Analysis of thermal performance of underground wine cellar

Abstract

El control de la temperatura es fundamental para el envejecimiento del vino, lo que representa mayor tiempo de uso de sistemas electromecánicos para enfriamiento y humidificación interior, que incrementa el costo operativo de las cavas de vino. Los edificios subterráneos representan una solución constructiva para maximizar el desempeño térmico y la eficiencia energética, al utilizar las propiedades termofísicas del subsuelo para la reducción de la oscilación de la temperatura interior, sin embargo, dicho efecto dependerá de las características del edificio y del lugar de estudio. El objetivo del presente trabajo fue analizar el desempeño higrotérmico de una cava de vino subterránea ubicada en el Valle de Guadalupe, México, con datos de temperatura de bulbo seco y humedad relativa, obtenidos por monitoreo durante 1 año. De manera asincrónica se midieron las condiciones del exterior con una estación meteorológica. Para el análisis se consideraron rangos teóricos de temperatura y humedad óptimos para envejecimiento del vino con base en autores líderes en el tema. Los resultados mostraron el efecto del subsuelo y de las variaciones meteorológicas del exterior sobre las condiciones interiores para el periodo frío (diciembre a febrero) y el periodo cálido (junio a septiembre).

Temperature control is fundamental for the aging of wine, which requires more time of use of electromechanical systems for interior cooling and humidification that increases the operative cost of wine cellars. The underground buildings represent a constructive solution to maximize the thermal performance and energy efficiency, by using the thermophysical properties of the subsoil for the reduction of the interior temperature, however, this effect depends on the characteristics of the building and the study site. The main objective of the present work was to analyze the hygrothermal performance of an underground wine cellar in Guadalupe Valley Mexico, using data of dry bulb temperatura and relative humidity monitored for 1 year. The conditions of the external microclimate were measured asynchronously with a weather station. For the analysis, theoretical ranges of optimum temperature and humidity for wine aging are considered, based on literature of leading authors. The results show the effect of the subsoil and the meteorological variations of the exterior on the interior conditions for the cold period (December to February) and the warm period (June to September).
