<P>PROBLEM TO BE SOLVED: To solve the problems such that in conventional barns, since a method for blowing wind from the upward direction of each of the barn chambers and from the back surface of a multiple number of livestocks by suspending fans with a string, etc., at the ceiling surface of many barn chambers divided in the longitudinal direction of the barn by setting a prescribed range as one unit, generally and in the whole and prescribed regions, is used, an individual and efficient wind blowing for the livestocks can not be expected, and also by simply blowing and/or agitating air in the barn, it is impossible to aim at the cooling or changing of the air by introducing outside air. <P>SOLUTION: This method for air blowing is constituted by setting the barn with many barn chambers, arranging ducts with many penetrated holes at the ceiling surface of the barn chambers, installing a fan at the base end of the duct, sucking the outside air by the fan installed at a gap opening to the gable side plain of the barn, blowing down the sucked air from the back surfaces of livestocks by utilizing the penetrated holes at the lower surface of the duct and opening at the upper direction of each of the barn chambers. It is possible to blow wind optimum for the livestocks and also efficient for rearing. <P>COPYRIGHT: (C)2008,JPO&INPIT |
