Abstract

This study aimed to evaluate the thermal performance of a flood-type roof cooling system for broiler shed. In flood-type roof cooling system, flowing film of water cools down the inside air by decreasing the effects of incoming solar radiation on the roof temperature. Hourly roof ad indoor air temperature of the broiler shed with roof cooling system were measured and compared to those of control set-up (without cooling system). Modelling of hourly roof temperatures of broiler shed was performed using energy balance analysis. This approach considers the principle of conservation of energy in a steady-flow system requiring clear identification of all energy entering and leaving the system. Energy balance equation used in the flowing water assumed total solar radiation as the entering energy while latent heat and sensible heat of water together with the energy transferred inside the shed through combined convection and conduction were initially assumed as the outgoing energy. On the other hand, energy balance equation used in the inside air assumed energy transferred from the roof and the energy entered the wall due to solar radiation were the entering energy while the energy transferred outside through conduction in the wall was assumed as the outgoing energy. Results showed that the roof cooling system reduced the inside temperature of the shed up to 5 degree Celsius.
