Definitions

  • the present invention relates to a greenhouse.
  • the present invention relates specifically to a greenhouse comprising a cultivation system for cultivating crops therein, and an air circulation system comprising a fan device, and an air distribution hose which is in fluid connection with the fan device and is configured to distribute air to be supplied by the fan device over the crops to be cultivated in the cultivation system.
  • the present invention provides a greenhouse of the type stated in the preamble, with the special feature that the air distribution hose is formed by at least two air channels which are mutually separated over the length of the air distribution hose, and which lie adjacently of each other and are each configured to distribute air to be supplied by the fan device over the crops to be cultivated in the cultivation system.
  • mutually separated is understood to mean that the air channels are not in fluid connection with each other.
  • air is prevented from flowing from the one air channel to the other air channel.
  • Each of the air channels is therefore configured to distribute the air over the crops to be cultivated in the cultivation system separately from the other of the air channels.
  • Each of the air channels preferably comprises a plurality of outlet openings for distributing the air over the crops to be cultivated in the cultivation system.
  • the separation of the air distribution hose into at least two mutually adjacent air channels provides a plurality of particular advantages. Firstly, the separation into a plurality of air channels provides for the option of carrying a plurality of airflows with mutually differing air conditions through the air distribution hose. It is for instance possible to guide both a hot and a cold airflow to the crops to be cultivated and distribute them thereover using an air distribution hose.
  • the separation into a plurality of air channels moreover allows the shape of the outer contour of the air distribution hose, as seen in cross-sectional view, to be adapted to the application of the air distribution hose in the greenhouse. Since the outer surface of the air distribution hose forms the boundary surface between the airflows in the air channels and the area surrounding the crops to be cultivated in the cultivation system, the outer contour determines where on said boundary surface the air can be supplied to the crops by the air distribution hose. In this way the shape of the outer contour of the air distribution hose can therefore be chosen such that the air hose supplies the air to be supplied by the fan device at locations that are more favourable for crop growth than is achieved with conventional air distribution hoses.
  • conventional air hoses are generally cylindrical.
  • a division into for instance two mutually adjacent cylindrical air channels enables an air hose which, as seen in cross-sectional view, is twice as wide as it is high or vice versa, without the throughflow area, i.e. the overall surface area of the cross-sectional area of the interior of the air distribution hose, being reduced.
  • Such an air hose divided into a plurality of air channels is furthermore non-rotation- symmetrical about its longitudinal axis. Rotation about its longitudinal axis therefore enables the air distribution hose to be oriented optimally relative to the crops present in the cultivation system.
  • the air distribution hose obtains as it were the form of a mattress instead of a cylinder. It is noted for the sake of completeness that lying adjacently of each other is also understood to mean lying one above the other or lying obliquely adjacently or above each other. This depends on the position in which the air distribution hose is rotated about its longitudinal axis.
  • An air distribution hose in mattress form consisting of a horizontal row of air channels, can preferably be placed under a cultivation table, wherein an overall width of a row of air channels, as seen in cross-sectional view, corresponds substantially with a width of the cultivation table.
  • Such an air distribution hose has the advantage relative to a conventional cylindrical air distribution hose that the cultivation table can be placed lower in the greenhouse so that the height of the greenhouse can be utilized better. More air is in particular situated above the crops, which enhances the air circulation in the greenhouse.
  • a lowered cultivation system such as a lowered cultivation table or lowered cultivation gutter, also has the advantage that fruits of the crops can for instance be picked more easily, for instance because a ladder need no longer be used.
  • Such a distribution hose under the cultivation table moreover has the advantage that air can be supplied upward to the roots of the crops to be cultivated in the cultivation table over the whole width of the cultivation table, as seen in cross-sectional view. Because the air distribution hose extends in axial direction of the hose, the air can furthermore also be distributed over the whole length of the cultivation table.
  • Such an air hose can additionally be oriented vertically and be arranged between crops to be cultivated in the cultivation system. This has multiple advantages.
  • the air distribute hose can in this way be placed closer to the crops than is possible with conventional cylindrical air distribution hoses, since the vertically oriented mattress-like air distribution hose extends less far in the width direction, as seen in a cross-sectional view, than the conventional cylindrical distribution hose, while the overall surface area of the throughflow area of the air channels of the mattress-like air distribution hose need not be smaller than that of the conventional cylindrical air distribution hose.
  • a conventional cylindrical air distribution hose with a throughflow area equal to that of a mattress-like air distribution hose is wider and can therefore not be placed between the crops.
  • a placing of the air distribution hose closer to the crops allows, among other things, a lower flow rate of the air to be supplied to the crops without having an adverse effect on the degree of air circulation, which is advantageous for the crop growth and the quality of the crops to be cultivated.
  • Such an air hose between the crops to be cultivated in the cultivation system furthermore allows a plurality of airflows with mutually differing air conditions, particularly with mutually differing temperatures, to be carried through the air distribution hose so that air with different temperatures is supplied at different heights.
  • Using the air distribution hose it is thus for instance possible to supply hot air to a lower portion of a crop while cold air is supplied to an upper portion of the crop. This is particularly advantageous for determined types of crop.
  • an additional advantage is that such a mattress-like vertically oriented air distribution hose between the crops has a space-saving effect.
  • the assembly of cultivation system, air distribution hose and crops extends less far in the width direction than conventional assemblies, wherein large cylindrical air hoses are generally arranged under cultivation gutters, which air hoses are wider, as seen in cross-sectional view, than the cultivation gutters and the crops arranged therein.
  • Mutually adjacent cultivation systems, such as cultivation gutters can hereby be placed closer together without intermediate walkways being narrowed by the air hoses.
  • such a mattress-like vertically oriented air distribution hose allows the cultivation system, such as a cultivation table or a cultivation gutter, to be placed on the floor of the greenhouse and/or the crops to be placed in the open ground, since air circulation from below is in this way no longer necessary.
  • cultivation systems placed on the floor of the greenhouse have the advantage that the height of the greenhouse can be utilized better. More air is in particular situated above the crops, which enhances the air circulation in the greenhouse.
  • a cultivation system placed on the floor also has the advantage that fruits of the crops can for instance be picked more easily, for instance because a ladder need no longer be used.
  • the air distribution hose consisting of a vertical row of air channels therefore enables the cultivation in greenhouses to be brought closer to the ground or even to take place in the open ground.
  • the air distribution hose according to the present invention enables cultivation adjacently of or to a position below the air distribution hose, while current systems necessitate cultivation above the air distribution hose.
  • cultivation system is understood to mean any provision in a greenhouse in which the crops are cultivated, such as a cultivation tray, a cultivation table, a cultivation gutter and a cultivated strip in the greenhouse, wherein the crops are cultivated in the open ground, and the like.
  • Both the horizontally oriented mattress-like air distribution hose under the cultivation table and the vertically oriented mattress-like air distribution hose between the crops provide more control over the air distribution over the crops than a conventional cylindrical air distribution hose placed under cultivation gutters because, as stated, the shape of the outer contour and the associated outer surface can be adapted to the cultivation system and/or the crops to be cultivated therein.
  • An air distribution hose divided into a plurality of air channels also allows a configuration wherein the air channels form a two-dimensional series, for instance a 2x2 or a 3x3 series.
  • An air distribution hose with such a configuration of air channels enables a substantially rectangular outer contour.
  • Such an air distribution hose is for instance suitable for use under a cultivation gutter and has the particular advantage that it does not protrude outside the cultivation gutter, so that mutually adjacent cultivation gutters can be placed closer together without intermediate walkways being narrowed. Less space is in this way taken up by the air distribution hose, and more space can therefore be utilized in the greenhouse for cultivating the crops.
  • the air channels of the air distribution hose can be mutually connected via their outer surfaces, but can also lie clear of each other.
  • the air distribution hose is then formed by a group of separate air channels which together are associated with said cultivation system.
  • mutually adjacent air channels of the at least two air channels share an outer channel wall and the mutually adjacent air channels are mutually separated by an inner wall lying between the air channels. Because the outer channel wall is shared by the mutually adjacent air channels, the separation of the air distribution hose into the at least two air channels has at most a limited influence on the shape of the outer contour of the air distribution hose, as seen in cross-sectional view.
  • the dimension of the inner wall is equal, as seen in cross-sectional view, to the overall dimension of each of the mutually adjacent air channels in an extending direction of the inner wall. This entails that the shape of the outer contour of the air distribution hose does not change due to the separation of the air distribution hose into the at least two air channels.
  • the dimension of the inner wall is smaller, as seen in cross-sectional view, than the overall dimension of each of the mutually adjacent air channels in an extending direction of the inner wall.
  • the shape of the outer contour of the air distribution hose is hereby changed relative to the same air distribution hose without inner wall.
  • each of the at least two air channels has its own channel wall which, as seen in cross-sectional view, forms a closed loop around its respective channel.
  • the channel walls of the air channels of each of the at least two air channels are mutually connected with their outer surfaces.
  • the at least two air channels are configured as at least one row of mutually separated air channels lying adjacently of each other.
  • a row of mutually adjacent, mutually separated air channels can for instance be arranged under a cultivation table, wherein the row extends in horizontal direction.
  • Such a configuration makes it possible to ensure that the air distribution hose does not extend outside the table, and also makes it possible to provide the crops in the cultivation table with air circulation over the whole width and length thereof.
  • Such a row can alternatively for instance be arranged between crops which grow upward, wherein the row extends in vertical direction.
  • Such a configuration allows the air to be supplied by the fan device to be supplied closer to the crops.
  • Such a configuration also allows air of different temperatures to be supplied at different heights between the crops. This configuration moreover saves space and the configuration enables crops to be cultivated in open ground since the air distribution hose is situated above the cultivation system instead of under the cultivation system, as is the case in a conventional assembly of cultivation system and air hose.
  • the at least one row comprises two or more rows, lying one above the other, of mutually adjacent, mutually separated air channels.
  • the two or more rows lying one above the other comprise a two-dimensional series of mutually separated air channels.
  • Such a configuration allows cultivation gutters in a greenhouse to be placed closer together, since the width of the air distribution hose can be adapted to the width of the cultivation gutter, as seen in cross-sectional view.
  • an air distribution hose with a configuration of air channels in for instance a 2x2 or 3x3 series enables a substantially rectangular outer contour.
  • This has the particular advantage that it does not protrude outside the cultivation gutter, so that mutually adjacent cultivation gutters can be placed closer together without intermediate walkways being narrowed. In this way less space is taken up by the air distribution hose, and more space can therefore be utilized in the greenhouse for cultivating the crops.
  • each of the at least two air channels are manufactured from a flexible material.
  • Air channels manufactured from a flexible material have the advantage that they can be adapted to the form of the cultivation system and that they can be made compact for transport.
  • the flexible material has material properties such that each of the at least two air channels takes on its shape by blowing air into the respective channel.
  • a particular advantage of inflatable air channels is that the air distribution hose can be flattened and/or folded when it is not in use, which is particularly advantageous for transport and storage of the air distribution hose.
  • each of the at least two air channels comprises blow-out openings for blowing out therethrough the air to be supplied by the fan device, and the respective blow-out openings of each of the at least two air channels are distributed over the length of the respective air channel such that the air to be supplied by the fan device is distributed via the blow out openings over the crops to be cultivated in the cultivation system.
  • the cultivation system is arranged suspended in the greenhouse, the air distribution hose is arranged under the cultivation system and the blow-out openings of the at least two air channels are positioned such that the air to be supplied by the fan device is blown out in mutually opposite lateral radial directions.
  • blow-out openings of at least an upper channel of the at least two air channels are positioned such, as seen in cross-sectional view, that the air to be supplied by the fan device is blown out in an upward direction. In this way the roots of the crops to be cultivated in the cultivation system can be aerated from below.
  • a bottom of the cultivation system is preferably provided for this purpose with air-transmitting openings.
  • the at least two air channels are configured as at least one row of mutually separated air channels lying one above the other, wherein the at least one row is arranged above the cultivation system such that the at least one row is situated between the crops to be cultivated in the cultivation system, wherein the blow-out openings of the air channels of the at least one row are positioned such that the air to be supplied by the fan device is blown out in mutually opposite lateral radial directions.
  • the air distribution hose is manufactured from a fluid-tight material and perforations serving as blow-out openings are arranged in the fluid-tight material.
  • the air distribution hose is manufactured from a woven textile and pores in the woven textile serve as the blow-out openings.
  • the fan device and the air distribution hose are configured such that the fan device makes an airflow flow in each of the at least two air channels, and the greenhouse further comprises an air treatment system for treating the air to be supplied by the fan device, wherein the air treatment system is configured to treat the air of a first airflow in a first of the at least two air channels and the air of a second airflow in a second of the at least two air channels in mutually differing ways, such that a property of the air of each of the first and the second airflow mutually differs.
