Description

  

  
 



  Dispositif pour le chauffage d'un sol
 En horticulture, on a souvent recours à des dispositifs de chauffage du sol, principalement dans la culture en serre, afin d'activer la croissance des plantes. Les dispositifs utilisés entrent pour la plupart dans trois catégories: le chauffage électrique du sol; le chauffage par circulation d'air; le chauffage par circulation d'eau.



   Le dispositif utilisant le chauffage électrique consiste simplement en un corps de chauffe isolé en forme de serpentin enfoui dans le sol et disposé dans un plan parallèle à la surface du sol. Ce dispositif est très peu employé pour des raisons économiques, car sa consommation électrique est relativement élevée.



   Le dispositif utilisant le chauffage par circulation d'air comprend des tuyaux en tôles galvanisées d'un diamètre relativement grand, ceci afin d'augmenter la surface en contact avec la terre environnante pour compenser en partie une déperdition calorifique importante.



   La circulation régulière de   l'air    chaud dans des tuyaux disposés dans le plan horizontal est difficile à obtenir, particulièrement lorsque les tuyaux sont longs.



  Un tel dispositif a un faible rendement. D'autre part, les tuyaux métalliques, quoique galvanisés, ne résistent pas à la corrosion due aux attaques chimiques et à l'humidité de la terre.



   Le dispositif utilisant le chauffage par circulation d'eau est employé presque exclusivement dans les serres et comprend une dalle de béton placée fixement sur des appuis, et sur laquelle sont disposés des tuyaux métalliques. Ces tuyaux métalliques sont recouverts par une plaque n'entrant pas en contact avec lesdits tuyaux et ménageant ainsi un espace d'air autour d'eux.



   Un tel dispositif peut difficilement être placé dans un sol n'ayant pas d'assise, par exemple dans un champ, car la dalle de béton reposerait directement sur la terre arable, elle ne supporterait pas les inévitables affaissements du terrain et se fendillerait.



   D'autre part, la dalle étant imperméable, elle empêche le passage d'eau et de gaz de la couche de terre située sur le dispositif à la couche de terre située sous le dispositif.



   La présente invention se rapporte également à un dispositif de chauffage du sol par circulation d'eau, mais permet d'éviter les inconvénients des dispositifs traditionnels.



   La présente invention a pour objet un dispositif pour le chauffage d'un sol, comprenant des tuyaux, dans lesquels circule un liquide préalablement chauffé, posés sur un support enfoui sous une couche de terre et disposés dans un plan sensiblement parallèle au niveau du sol.



  Ce dispositif est caractérisé en ce que ledit support est constitué par des plaques isolantes en matière poreuse, destinées à être posées librement dans le sol, la face supérieure des plaques présentant des canaux dans lesquels sont logés les tuyaux.



   La mise en place d'un tel dispositif peut facilement être effectuée par l'agriculteur lui-même et ne nécessite pas le concours de gens du métier pour couler une dalle de béton ou raccorder les tuyaux métalliques, par exemple. En outre, la composition de la plaque supportant les tuyaux permet une bonne isolation thermique augmentant encore le rendement de l'installation équipée d'un tel dispositif.



   Le dessin annexé représente, schématiquement et à titre d'exemple, une forme d'exécution de l'objet de l'invention.



   La fig. 1 est une vue générale du dispositif selon l'invention.



   La fig. 2 est une coupe selon la ligne I-I de la fig. 1.



   La fig. 3 représente, à plus grande échelle, un détail de la fig. 1.



   Le dispositif représenté à la fig. 1 comprend une plaque 1 ondulée, en fibres d'amiante liées au ciment et dont les dépressions de la surface forment des canaux  2 parallèles dans lesquels sont posés les tuyaux 3 de chauffage. Ces tuyaux sont en matière plastique et présentent une paroi relativement épaisse, afin d'éviter l'écrasement par la masse de terre qui les recouvrira.



   Le circuit de chauffage proprement dit comprend une conduite d'amenée 4, par laquelle arrive l'eau préalablement chauffée dans une chaudière, non représentée au dessin, un cylindre de distribution 5 duquel partent les différents tuyaux 3, un collecteur 6 et une conduite de retour 7. Les extrémités 10, respectivement 11, des tuyaux 3 sont raccordées sur des bouches de départ 12 du collecteur 6 et du cylindre de distribution 5, et maintenues fixement par des bagues de serrage 13.



   La mise en place du dispositif se fait de la manière suivante:
 On dame la couche du sol 8, fig. 2, sur laquelle on veut placer le dispositif, de manière à obtenir une surface relativement plane. On dispose sur cette surface une ou plusieurs plaques ondulées 1 suivant l'étendue du terrain dans lequel on veut installer le chauffage, le bord d'une plaque chevauchant le bord de la plaque suivante.

 

   On pose ensuite les tuyaux plastiques 3 dans les canaux parallèles 2 et on raccorde les extrémités 10, respectivement 11, des tuyaux 3, d'une part, sur le cylindre de distribution S et, d'autre part, sur le collecteur 6. Les tuyaux 3 sont ensuite recouverts d'une couche de terre 9 dont l'épaisseur varie suivant la culture envisagée, atteignant en moyenne 30 cm.



   Le dispositif représenté à la fig. 1 constitue une unité de chauffage dont la pose peut être répétée suivant l'étendue du terrain à chauffer, les différentes plaques pouvant se placer côte à côte (fig. 2) ou dans le sens de prolongement des canaux 2. 



  
 



  Device for heating a floor
 In horticulture, soil heating devices are often used, primarily in greenhouse cultivation, to stimulate plant growth. Most of the devices used fall into three categories: electric floor heating; heating by air circulation; heating by water circulation.



   The device using electric heating consists simply of an insulated heating body in the form of a coil buried in the ground and arranged in a plane parallel to the surface of the ground. This device is used very little for economic reasons, because its power consumption is relatively high.



   The device using air circulation heating comprises galvanized sheet pipes of a relatively large diameter, in order to increase the surface in contact with the surrounding earth in order to partly compensate for a significant heat loss.



   The regular circulation of hot air in pipes arranged in the horizontal plane is difficult to achieve, especially when the pipes are long.



  Such a device has a low efficiency. On the other hand, metal pipes, although galvanized, do not resist corrosion due to chemical attacks and moisture from the earth.



   The device using water circulation heating is used almost exclusively in greenhouses and comprises a concrete slab fixedly placed on supports, and on which metal pipes are arranged. These metal pipes are covered by a plate which does not come into contact with said pipes and thus leaves an air space around them.



   Such a device can hardly be placed in a ground having no foundation, for example in a field, because the concrete slab would rest directly on the topsoil, it would not withstand the inevitable subsidence of the ground and would crack.



   On the other hand, the slab being impermeable, it prevents the passage of water and gas from the layer of earth located on the device to the layer of earth located under the device.



   The present invention also relates to a device for heating the ground by circulating water, but makes it possible to avoid the drawbacks of traditional devices.



   The present invention relates to a device for heating a floor, comprising pipes, in which circulates a previously heated liquid, placed on a support buried under a layer of earth and arranged in a plane substantially parallel to the level of the ground.



  This device is characterized in that said support is constituted by insulating plates of porous material, intended to be placed freely in the ground, the upper face of the plates having channels in which the pipes are housed.



   The installation of such a device can easily be carried out by the farmer himself and does not require the assistance of those skilled in the art to pour a concrete slab or connect the metal pipes, for example. In addition, the composition of the plate supporting the pipes allows good thermal insulation, further increasing the efficiency of the installation equipped with such a device.



   The appended drawing represents, schematically and by way of example, an embodiment of the object of the invention.



   Fig. 1 is a general view of the device according to the invention.



   Fig. 2 is a section along the line I-I of FIG. 1.



   Fig. 3 shows, on a larger scale, a detail of FIG. 1.



   The device shown in FIG. 1 comprises a corrugated plate 1 made of asbestos fibers bonded to the cement and the depressions of which on the surface form parallel channels 2 in which the heating pipes 3 are laid. These pipes are made of plastic and have a relatively thick wall, in order to avoid crushing by the mass of earth which will cover them.



   The actual heating circuit comprises a supply pipe 4, through which the water previously heated in a boiler, not shown in the drawing, arrives, a distribution cylinder 5 from which the various pipes 3 leave, a manifold 6 and a supply pipe. return 7. The ends 10, respectively 11, of the pipes 3 are connected to the outlet ports 12 of the manifold 6 and of the distribution cylinder 5, and held fixedly by clamping rings 13.



   The device is put in place as follows:
 The layer of soil 8, fig. 2, on which we want to place the device, so as to obtain a relatively flat surface. One or more corrugated plates 1 are placed on this surface depending on the extent of the land in which the heating is to be installed, the edge of one plate overlapping the edge of the next plate.

 

   The plastic pipes 3 are then placed in the parallel channels 2 and the ends 10, respectively 11, of the pipes 3 are connected, on the one hand, to the distribution cylinder S and, on the other hand, to the manifold 6. The pipes 3 are then covered with a layer of earth 9, the thickness of which varies according to the crop envisaged, reaching on average 30 cm.



   The device shown in FIG. 1 constitutes a heating unit, the installation of which can be repeated depending on the extent of the ground to be heated, the different plates being able to be placed side by side (fig. 2) or in the direction of extension of the channels 2.
