装置。 The lower end 1 of the vinyl sheet in the greenhouse is tied to a wire or rope 2 for raising and lowering the sheet, and the wire or rope 2 is connected to a wire or rope winding mechanism 4 incorporating a shape memory alloy and a coil spring, and the room temperature rises above a predetermined temperature. At this time, the shape memory alloy 6 incorporated in the wire winding mechanism 4 changes its shape to wind the wire or rope 2, and the lower end 1 of the vinyl sheet is pulled up to open the ventilation hole. Also, when the room temperature drops below a predetermined temperature, the shape memory alloy 6 built into the wire winding mechanism 4 expands, causing the coil spring 9 to expand.
This ventilation system for an agricultural greenhouse is characterized in that the lower end 1 of the sheet is pulled down by the gravity of a round bar 5 attached to the lower end 1 of a wire or rope 2, and the ventilation opening is closed.
