Abstract

The aim of the present study was to investigate the effects of natural ventilation system with underground pipe which is
an alternative ventilation system for temperature, relative humidity and air flow rate parameters in the calf stall indoor
environment during the winter, when animals continuously stay in the barn. The temperature, relative humidity and air
flow rate values of stall interior and outdoor air were continuously measured during the months of December, January,
February, March by applying natural ventilation system with underground pipe and traditional ventilation system with
windows in a 48 head calf barn with a floor area of 150 m2 . Measured parameters in both ventilation systems were
statistically compared.In the wake of implementing; It has been observed that the natural ventilation system with
underground pipe in the calf barn in frigid meteorological conditions has a statistically better good achieve on the
temperature, relative moisture and air flow rate criteria inside the stall than the traditional ventilation system carried out
with windows.In the natural ventilation system with underground pipe, the outside air is taken from the exterior surface
of ones of the lengthy sides of the barn, passes under the barn floor transversely and enters the stall from inner surface of
the other lengthy side of the barn. Thus, outside air coming in the stall through underground pipes becomes warmer than
the outside air picked up into the barn by windows. In addition, since the air taken into the barn with the underground
pipe ventilation system penetrates directly into the ground and comes out of the chimneys, it allows the air inside the
barn to be cleaned faster than traditional ventilation systems.
