Abstract Ventilation systems for poultry and livestock farming are methods of producing man-made wind (artificial wind). The wind produced from the exhaust air of these ventilation systems could be used to generate electrical energy using wind turbines. In this research, a ventilation energy recovery system for poultry houses was investigated using a Horizontal Axis Wind Turbine (HAWT). The performance of the ventilation system is very important as affected by any obstacle specially when placing the wind turbine in front of the extractor fan. Which could have a negative effect on the system. For executing this research, a primary study was confirmed to examine the effect of obstacles on the ventilation system performance of the (extractor fan rotating speed, its consumption of electrical current, and the static pressure inside the poultry house). The extractor fan shutter blades have been used as obstacles to obtain different blockage percentages. The blockage percentages were zero (full open), 25%, 50%, 75% and 100 % (full closed). |
