|Title:||Simulation Of An Alternative Floor Heat Source In Broiler Production Using Solar Energy|
De Alencar Naas I.
|Abstract:||Even under tropical and subtropical climate conditions, raising chicks within the thermal comfort zone is a challenge. The supplementary heat source normally used by producers in order to maintain 29-31°C in the building is obtained through burning GLP, associated with electrical thermal resistance. In some periods of the years 80 bottles of 13 kg of gas is needed for raising the flock's first three weeks. While this main need of energy is during the night, during daytime there is an exta heat supply coming from the solar radiation, which has not been used by the producers. The main objective of this research was to develop an alternative solar heat source to supply the heat need for raising chicks, using the thermal inertia applied concept. The principle is based upon the use of a heated floor, with a thickness of 0.30 m, and a full scale tank of heated water below the floor. A solar collector heats the water during daytime and, because of the concrete floor inertia, the heat migrates to the inside environment during the night. The simulated projected system using 15 solar collectors of 3 m 2, with the slope of 35 degrees was able to heat to a comfort zone, a flock housing of 90 m 2, during the coldest winter months.|
