The appropriate operation of a tunnel ventilation system provides drivers passing through the tunnel with comfortable and safe driving conditions. Tunnel ventilation involves maintaining CO pollutant concentration and VI (visibility index) under an adequate level with operating highly energy-consuming facilities such as jet-fans. Therefore, it is significant to have an efficient operating algor...

a study was conducted to compare the growth performance as well as blood and carcass variables of two broiler strains reared in a conventional broiler house and a modified greenhouse equipped with cooling pads and tunnel ventilation system. eight hundred day-old chickens of two commercial strains (ross  308 and lohmann) were selected and placed in  8 floor pens (4 pens of  50 broilers for each ...
