An Evaluation of the Potential of an Air-conditioning System using the Earth-to-Air Heat Exchanger Duct

Abstract

The purpose of this research was to evaluate the potential of an air conditioning system using theearth-to-air heat exchanger duct experimentally for all seasons of Thailand. The results from theexperiment showed that this system could control the air condition in the building for both heating andcooling modes. The heating mode was suitable during nighttime of a cool season, while the cooling modewas suitable for daytime of a hot season. The ability of the air conditioning system to provide a comfortablelevel was found only during the heating mode in the cool season. However, during the cooling mode in thehot season it could effectively decrease the heat accumulation within the building.
