Tunnel ventilation

As discussed in the previous newsletters in this series, in order to insure uniform bird cooling in a tunnel-ventilated house air speed throughout the house needs to be as uniform as possible. Side wall smoothness and equipment installation can have a significant effect on air flow patterns within a tunnel-ventilated broiler house and therefore affect bird cooling. Though broiler houses make up the majority of tunnel-ventilated houses, tunnel ventilation is also widely used in broiler-breeders and commercial layer housing to maximize bird cooling during hot weather. Though in general, tunnel-ventilated broiler breeder and commercial layer houses are similar in design to broiler houses, there are differences which provide additional illustrations of how house layout and equipment installation affects air flows in tunnel-ventilated houses.
