Thermal Resistance by Phase Change Materials of the Double Roof System
This research studies about the possibility of Phase change materials for development with the double roof system which uses the Radiant barrier to reduce the heat into the house and to reduce load of the air conditioner. The experiment was divided into 4 patterns. The Radiant barrier and the Phase change materials are on top of the air passage (model 1). The Phase change materials and the Radiant barrier are on top of the air passage (model 2). The Radiant barrier is under the roof and the Phase change materials is under the air passage is (model 3). The Radiant barrier is under the air passage and the Phase change materials is under the roof (model 4). By building the test room sizes 90×90 cm2 and the air passage sizes 10 cm. The heat source from the heat generator in temperature is 45, 50, 60. The results revealed that if the Radiant barrier is under the roof and the Phase change materials is under the air passage, temperature will tend to decrease by the heat transmission into the house decrease about 3-5 in the experiment. The above-mentioned decrease of the temperature, the calculation of the thermal energy per unit area in (model 3) can decrease the most quantity of heat flux more than the other patterns by average at 19.66, 22.5 and 29.14 W/m2 respectively. From the experiment was found that (model 3) has the appropriate position for development more than the other patterns.
