Abstract
Convective roof cooling operates using water as refrigerant. It consists in convection process pass through over the roof, thus decreasing the roof temperature. This system has a great potential to provide thermal comfort in places where roof temperature is low. However, thermal efficiency from the previous research which it is use water as refrigerant is still low. A way to solve this problem is to use methanol as a refrigerant. Following, this paper analyzes some operation parameters such as: roof and room temperature and heat transfer rate. The paper shows the conditions for the best operation point, with regard to thermal conditions of roof and room temperature.
