BAY-TYPE GREENHOUSE WITH OPTIMAL PERFORMANCE.

摘要

The invention relates to a greenhouse of the "bay" type intended to be installed in "multi-bay" runs occupying several thousand square metres at once, this "bay" type greenhouse being made up of a plurality of structural units installed parallel to one another along the entire length of the main tunnel. According to the invention, with the greenhouse being such that the ratio of the distance (F) between the top (C) of the greenhouse and the horizontal straight line passing through the upper ends of the lateral posts (PLG, PLD) to the width of the main tunnel (LN) is less than 1/5, this dimensional ratio notably presenting a major problem of condensation in the middle of the greenhouse, this greenhouse also has a double central opening section (OG, OD), the transverse profile of the greenhouse with the opening section closed being such that, on each side of the greenhouse, the angle formed between the straight line tangential to the bow (Cid, CiG) in the transverse plane of the greenhouse level with the lateral lintel (LD, LG) and the straight line passing through the axis of articulation and the end of the closed lateral opening section (OD, OG) in the transverse plane of the greenhouse is non-zero in the direction of a concavity of the profile of the greenhouse, this break in slope giving the closed opening section (OD, OG) a slope greater than or equal to 15°.
