The inner wall surface and the floor face of the barn which begins the poultry house, being the system which the fixture or the air etc disinfectant purity is done, being based on the specification which it sets beforehand in the sodium hypochlorite solution tank and the filter, and the aforementioned tank which are arranged on barn top vis-a-vis the tubular blower and measure the air temperature inside the barn the temperature sensor and the said temperature sensor which distribution facilities are done in the inhalation section chamber and the top inside the barn which possess the disinfectant pure section for the introduction air which has the injection section of the sodium hypochlorite solution which from the transportation liquid tube which connected facilities is done is supplied inside the aforementioned tubular blowerIt has with the control section and the air exit which control operation, the said control section, comparing calculating the aforementioned specification and the aforementioned measurable quantity with the appropriate sampling time, when the said measurable quantity exceeds specification, as compared to in order to send out the air inside the barn to power, controls the operation of the aforementioned tubular blower, with the aforementioned inhalation section chamber the disinfectant introduction air which purity is done, blowing out from the inhalation section chamber, it satisfies inside the barn, is discharged from the aforementioned air exit by the aforementioned tubular blower鶏舎をはじめとする畜舎の内壁面、床面、備品、又は空気等を除菌清浄するシステムであって、畜舎上部に配置された次亜塩素酸ナトリウム溶液タンクと、フィルタ、及び前記タンクに連設された輸液管から供給される次亜塩素酸ナトリウム溶液の噴射部を備える導入外気用の除菌清浄部を内部に具備した吸気部チャンバと、畜舎内の上部に配設された筒状ブロアと、畜舎内の気温を測定する温度センサと、該温度センサに対して予め設定した設定値に基いて前記筒状ブロアの動作を制御する制御部と、排気口とを備え、該制御部は、前記設定値と前記測定値を適宜サンプリングタイムで比較演算して、該測定値が設定値を超えるときはより強力に畜舎内の空気を送り出すよう前記筒状ブロアの動作を制御し、前記吸気部チャンバで除菌清浄された導入外気は、吸気部チャンバから吹出して畜舎内を充たすと共に、前記筒状ブロアによって前記排気口から排出される
