Description
Summary:Nowadays, many buildings wield indoor water features such as waterfalls, fountains, and water curtains to improve their aesthetical value. Despite the provision of air cooling due to water evaporation, this feature also has adverse effect if applied in warm humid climate since evaporation might increase air humidity beyond the comfort level. Yet, there are no specific researches intended to measure water feature's effect upon its thermal condition. In response, this research examines the influence of evaporative cooling on indoor wall fountain toward occupant's thermal comfort in warm humid climate. To achieve this goal, case study is established in Waroeng Steak Restaurant's dining room in Surakarta-Indonesia. In addition, SNI 03-6572-2001 with comfort range of 20.5-27.1°C and 40-60% of relative humidity is utilized as thermal criterion. Furthermore, Computational Fluid Dynamics (CFD) is employed to process the data and derive conclusions. Research variables are; feature's height, obstructions, and fan types. As results, Two Bumps Model (ToB) is appropriate when employs natural ventilation. However, if the room is mechanically ventilated, Three Bumps Model (TeB) becomes the best choice. Moreover, application of adaptive ventilation is required to maintain thermal balance.
