Distribution of water vapor in the atmosphere of the room poultry houses is usually an effective and economical solution to reduce heat stress of the chickens. Experimental studies were conducted in a small saloon located in the farm machinery department of shiraz university. The rotary cup fogging system consisted of a cup which was derived by DC motor. Rotational speed of the cup caused the water distributed into the air in a small particles.The effects of rotary speed of cup (at three levels), cup materials, and the quality of cup inner surface were investigated.
Results revealed that increasing in the rotary speed of cup causes an increase in the relative humidity of the room and decreasing the room temperature. İncreasing in the cup rotary speed caused an increase in the fraction of water which was vaporized (β). The cup material was significantly affect on the in/out temperature ratio. The mentioned ratio was lower for Teflon cup than aluminum one.
