Abstract
Heating, Ventilation and Air-Conditioning (HVAC) systems are commonly used in both residential and commercial buildings. Although many of these systems can provide the necessary thermal comfort level, they often lead to excessive energy consumption. Hence, reliable HVAC systems are required in order to comply with environmental constraint while providing the best thermal comfort- energy consumption ratio. In this paper, thermal behavior of a simplified building comprised of two similar adjacent spaces has been modeled in order to assess the performance of a combined floor radiant heating and ceiling radiant cooling. The thermal simulation of the building has been performed by using the Bond Graph modeling approach, where both temperatures and heat flux annual profiles have been calculated. Comparison with TRNSYS software results has also been made. It was found that the combined floor radiant heating and ceiling radiant cooling is able to meet energy demand of the building insuring a good thermal comfort level. However, the selected heating/cooling technique is rather more useful for cold and dry climate.
