Abstract

A process to grow plants in a greenhouse includes supplying cooled air to the interior of the greenhouse and supplying irrigation water to the plants. The cooled air is obtained by directly cooling air against evaporating water in one or more cooling pads where water flows downwardly via an open structure and in which open structure the air directly contacts the evaporating water to obtain cooled air and non-evaporated water. Part of the non-evaporated water is used as irrigation water and part is reused in the one or more cooling pads.

Abstract

Greenhouse for growing a cultivation comprising of a floor (2), walls (3), a roof (4) and numerous parallel positioned and suspended elongated cultivation gutters (6) at a distance above the floor (2) in a cultivation space (7). Between the floor (2) and the elongated cultivation gutters (6,6a,6b) numerous parallel positioned ventilation conduits (10) are present which ventilation conduits (10) are spaced apart from each other by an elongated working space A. A ventilation conduit (10) can individually adopt an expanded position (11) when distributing air and a collapsed position (12). The ventilation conduit (10) in its collapsed position (12) has an adjoining working space A which is larger than a working space A defined by two adjoining ventilation conduits (10) in their expanded position (11).

Abstract

A process for conditioning the air within a greenhouse comprising transparent walls and a structure including one or more ridge beams as part of a roof of the greenhouse. The process comprises maintaining a pressure difference between an average pressure within the greenhouse and a pressure exterior to the greenhouse, taking in air from the exterior of the greenhouse and mixing this air with air taken from the interior of the greenhouse to obtain conditioned air, distributing the conditioned air via a forced flow to the interior of the greenhouse, and discharging a volume of air from the interior of the greenhouse via openings present in the one or more ridge beams such to maintain the pressure difference.
