SIMULATION MODEL OF ENERGY BALANCE FOR POULTRY HOUSES

Abstract

The main aim of this research was to develop a simulation model of energy balance of the poultry house to predict the energy gain or loss of poultry houses that made of different materials in order to save energy and reduce costs. This could be achieved through studying the external loads are transmission, fenestration, perimeter, ventilation and infiltration at different poultry houses. The results showed that the energy requirement for heating poultry house decreases with increasing chicken age (40 days). The energy requirement for heating was decreased from 3716.75 to 247.65, 2731.31 to 10.79, 2417.98 to 66.14 and 2418.06 to 66.18 Kwh for first, second, third and fourth houses, respectively, when the chicken age increased from 1 to 40 days in Faiyum city. The energy requirement for heating was decreased from 6602.23 to 701.29, 5030.31 to 364.65, 4534.72 to 255.98 and 4534.86 to 255.99 Kwh for first, second, third and fourth houses, respectively, when the chicken age increased from 1 to 40 days in Benha city. The energy requirement for ventilation was increased from 1517.24 to 4083.08, 1325.53 to 3326.87, 1262.20 to 3084.95 and 1262.21 to 3085.00 Kwh for first, second, third and fourth houses, respectively, when the chicken age increased from 1 to 40 days in Faiyum city. The energy requirement for ventilation was increased from 2373.09 to 6793.56, 1991.44 to 5477.08, 1867.80 to 5060.30 and 1867.81 to 5060.41 Kwh in Benha city, when the chicken age increased from 1 to 40 days. The model results were in a reasonable agreement with the experimental ones.
