| Description: |
The constructions including phase change materials (PCMs) have been confirmed effective in indoor cooling because of the large thermal storage effect, especially when combined with night ventilation to enhance heat dissipation during nighttime and heat absorption during daytime. Based on a PCM-based radiant floor cooling system studied in Indonesia, which could maintain indoor thermal comfort and meet the local lifestyle of daily activities on the floor, this study developed an upgraded floor system, including PCMs inside raised floor panels, underfloor air conditioning (AC), and underfloor Fan. A field measurement was conducted in a residential unit in Tegal, Indonesia, with four nocturnal ventilation modes: no operation of AC and Fan, operation of Fan only, operation of AC only, and controlled operation of Fan and AC. The results showed that the PCMs could effectively reduce indoor air temperature by up to 3.6℃, supplemented by cooling from Fan and AC. The logical combination of Fan and AC was recommended as it could provide intensive cooling while saving 29.3% energy compared to operating AC all night. Therefore, this upgraded floor system has the potential to be promoted as the low-carbon cooling system for new construction and renovation of the housing in hot-humid climates. |
