    Abstract

    The study aims to assess the cooling performance of the automatic water spraying on the roof surface to decrease the indoor air temperature in a humid tropical climate. The spraying water onto the ceiling can be considered as an evaporative cooling strategy. Firstly, the approach has been tested in a cell test constructed with plywood for the walls and floors, and roofs of corrugated zinc sheet. It is necessary to note that water spraying can reduce the roof surface temperature by an average of 5°C. However, the reduction of roof temperature cannot be guaranteed to reduce the average indoor air temperature directly. To reach a greater advantage of the ceiling temperature reduction is required to spray water in around 10-15 minutes and conducted continuously. Secondly, it has been applied an automatic water spraying on the roof. The utilisation of sensors, actuators and controllers are an inseparable part, with the intention of this device will respond vigorously when the roof surface temperature reached a certain threshold, and automatically turns on the pump to spray water. The device has been practising; it still needs more elaboration for its reliability and investigations about reusing water after sprayed for allowing to reduce energy consumption in the buildings.
