An environment cleaning system for an animal breeding house has an outside environment, a breeding house, an air covering, and a cleaning device. The breeding house is deposited in the outside environment. The air covering is deposited in the outside environment and is mounted around the breeding house. The air covering is used to buffer the air pressure between the outside environment and the breeding house. The cleaning device is deposited in the outside environment, is connected to the air covering and the breeding house, and has an air exchanging unit and at least one filtering unit. The air exchanging unit controls the relative pressure among the outside environment, the air covering, and the breeding house to provide a unidirectional air flowing effect, and the flowing direction of the air is based on the relative pressure between the breeding house and the air covering.本發明為一種動物飼養舍環境清潔系統,包括有一空氣環境、一飼養舍、一清潔處理設備以及一氣套,該飼養舍係為一封閉空間,該清潔處理設備連接於該空氣環境與該飼養舍,且包括一氣體交換單元,該氣體交換單元係與該空氣環境與該飼養舍進行氣體交換,以控制該飼養舍與該空氣環境的相對氣壓,因此本發明可使該飼養舍與該空氣環境之間的氣體流通具有單向性,而達到防疫之功效,該氣套相對該空氣環境形成一封閉空間,且該飼養舍設置於該氣套內,其中,該清潔處理設備係以該氣體交換單元連接於該空氣環境、該氣套與該飼養舍,該氣體交換單元控制該飼養舍、該氣套與該空氣環境的相對氣壓。10‧‧‧空氣環境20‧‧‧飼養舍30‧‧‧氣套40‧‧‧清潔處理設備41‧‧‧氣體交換單元42‧‧‧除菌單元43A、43B‧‧‧過濾單元44‧‧‧開關閥
