A kind of guiding structure of greenhouse cooling air-flow,It is that the air intake vent that can also install waterwall simultaneously is equipped at at least side of a greenhouse surrounding,And a gas-permeable nets are covered in the indoor top eminence of temperature,Simultaneously greenhouse roof on other sides of book office or greenhouse surrounding side,If one with high what gas-permeable nets and air-vent in the what greenhouse of position,And it is installed with the suction air-guiding aisle of exhaust fan thereon； Therefore when fanning suction that the indoor hot-air of temperature is outside through said exhaust,It allows in greenhouse and forms negative pressure and introduce cool ambient air via air intake vent,And go out the high what gas-permeable nets of air-vent of warm room air by what suction,Along with gas-permeable nets act on the damping that air flows in greenhouse,The indoor cold air of temperature is allowed to be able to being uniformly distributed for wide area,And make in flowing from bottom to top,Enable the high hot-air of eminence in greenhouse directly by upward and outward as air-flow is discharged,And then cool house effect is promoted,And it can avoid the indoor plant of temperature and plant the generation for having localized hyperthermia at space.一種溫室降溫氣流的導引構造，是一溫室四周的至少一側處設有亦可同時裝設水牆的入風口，並在溫室內的上方高處覆設有一透氣網，同時溫室的屋頂上預定處或溫室四周的其它側之一側，設一具有高於透氣網而位於溫室內之引風口、且其上裝設有排風扇的吸排導風通道；故透過上述排風扇將溫室內的熱空氣向外吸排時，讓溫室內形成負壓而將外界冷空氣經由入風口引入，並由於吸排出溫室內空氣的引風口高於透氣網，再加上溫室內透氣網對空氣流動的阻壓作用，讓溫室內的冷空氣得以廣域的均勻分佈，且使呈由下而上的流動，令溫室內高處的高熱空氣直接被向上而往外隨著氣流排出，進而提升冷房效果，並可避免溫室內的植栽空間處會有局部高溫的發生。
