| Research Abstract |
The purpose of this research is to propose and evaluate passive cooling wall using phase change material for residences in hot humid region. First, we conducted a questionnaire survey and field measurements on residences in Southeast Asia, and revealed their indoor thermal conditions and characteristics of energy consumption. Second, we proposed a passive cooling system that combines phase change material (PCM) with night ventilation. For the proposed system, we also developed a new PCM panel which was integrated with copper foam. We measured its thermal performance by testing with a scale model house. Finally, a heat transfer analysis program was developed for optimal design of the PCM panel and evaluation of its effect on indoor thermal environment.
