A system for stirring and changing the air in a green house is provided to facilitate the installation and maintenance by installing a forward/reversely rotatable air blower on the ceiling of the green house. A system for stirring and changing the air in a green house(10) comprises: at least one air blower(20) which is installed to hang the ceiling of the green house; and a control part(30) which drives the forward and reverse rotation of an air blowing fan. The air blower comprises: a pipe-shaped housing of which both sides are open; a straight part extended to the inlet of one side of the housing; an enlarged pipe part formed at the inlet of the other side of the housing; and an air blowing fan mounted between the straight part and the enlarged pipe part. The air blowing fan sucks air from one of the inlet of the straight part and the inlet of the enlarged pipe part and then exhausts the air to the other inlet. The inlet of the straight part faces one side wall having a door. |
