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.
Claims18
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 comprising:
- 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,
- wherein the discharge of air via the openings in the one or more ridge beams is performed via openings that direct the air in a sideways direction relative to the one or more ridge beams, and
- wherein a rotatable valve rotating over an axis parallel to the one or more ridge beams is used to either direct the majority of the air to one side or to the other side.
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 comprising:
- 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,
- wherein the greenhouse comprises:
- transparent walls;
- and
- a structure including at least one ridge beam as part of a roof of the greenhouse,
- wherein the at least one ridge beam extends a distance above the roof defining two elongated side zones present above the roof and at either side of the ridge beam,
- wherein the at least one ridge beam includes one or more elongated hollow spaces,
- wherein the at least one ridge beam is provided with one or more closable openings in both side zones, the openings fluidly connecting the exterior of the greenhouse with the one or more elongated hollow spaces of the at least one ridge beam, and
- wherein the at least one ridge beam is provided with one or more openings at its lower end fluidly connecting the interior of the greenhouse with the one or more elongated hollow spaces of the at least one ridge beam, wherein the at least one ridge beam comprises an elongated valve and a fixed part, the valve is movable between at least (i) a first position relative to the fixed part. wherein the one or more openings in a first elongated side zone fluidly connecting the exterior of the greenhouse with the one or more elongated hollow spaces of the at least one ridge beam,
- wherein the one or more openings in an opposite second elongated side zone are closed, and (iii) a second position relative to the fixed part wherein the one or more openings in the second elongated side zone fluidly connect the exterior of the greenhouse with the one or more elongated hollow spaces of the at least one ridge beam, and
- wherein the one or more openings in the first elongated side zone are closed.
