Abstract

This cooling roof refers to the roof to be built into a closed system. The new roof cooling system is designed to help homeowners to obtain a moderate temperature inside the house space. In hot and humid areas, air conditioning is increasingly being used to achieve thermal comfort. The air conditioner is very intensive in terms of energy, and it is desirable to develop low energy alternatives to achieve comfort. This roof cooling system is designed to help reduce the temperature of the heat in the house to get a modest temperature. This cooling system has been built with a gable roof design as the main design for this system because of the frequently used designs in terraced houses due to low development costs. However, the purpose of this study is to help every homeowner able to have an appropriate roof-cooling system at an affordable price compared to the appropriate market price is no longer expensive. In addition, the roof is designed with a thermo-fluid concept that heat will be transferred through the water moving over the roofing material and the hot water will continue to be transferred to the cooling system. Water will be continued to recycle on the roof of the house. Heat transfer is a movement of a fluid such as water when it has been heated it will cause the heat or energy to move away and carry it to another place. The temperature change in the double roof is caused by the water flow in and out supported by a water pump that pushes the water to the roof. The system on reducing temperature is proven on the results experimented and this double roof is effectively changing the temperature from outside that enter to the house space. The water in that flow inside the double roof will bring out the heat from the roof to the water out. In this experiment, temperature change (± 6.7 °C) or 17.8 % heat has been reduced.
