Abstract

The invention is a device which makes it possible to reduce heat losses from a low-inertia building and, conversely, allows air conditioning. The principle of the installation starts with a tank 1 from which the heated water is pumped by a circulation pump 2 and sent by means of distribution tubes 3 into tubes placed in vertical and horizontal walls (ceilings). These tubes react in two ways: either by supplying heat to the construction when the water which is hotter than the ambient air circulates therein, which brings about radiation creating a thermal screen between the gaps left by the tubes or for air-conditioning when the circulation water is colder than the outside atmosphere and picks up heat, which brings about a fall in the ambient temperature. In the case of glass or plastic greenhouses, these tubes serve as a solar collector.

Description

La présente invention concerne un dispositif pour diminuer fortement la convection des airs chauds ambiants vers l'extérieur plus froid, ou, inversement, la convection de l'air frais intérieur vers un extérieur plus chaud, grace à un écran thermique composé de tubes à ecartement variable, formant double paroi intérieur où circule de l'eau plus chaude ou plus froide que l'air ambiant, suivant si l'installation est en apport calorique ou frigorique. Le principe sert aussi de capteur solaire. The present invention relates to a device for greatly reducing the convection of warm ambient air to the colder outside, or, conversely, the convection of fresh indoor air to a warmer outside, by virtue of a heat shield composed of spacing tubes variable, forming an inner double wall where water circulates hotter or colder than the ambient air, depending on whether the installation is in caloric or refrigerated supply. The principle also serves as a solar collector.

Le principe selon l'invention est un dispositif qui permet de diminuer fortement les déperditions des bâtiments de faible inertie ou de construction légère, tels que serres, hangards industriels, habitations légères. The principle according to the invention is a device which makes it possible to greatly reduce the losses of buildings of low inertia or of light construction, such as greenhouses, industrial hangars, light dwellings.

Un dispositif traditionnel, composé d'un écran thermique en plafond fait d'un film polyane ou d'un film aluminisé présente l'inconvénient d' être fermé la nuit, ouvert le jour, le gain en déperdition est de 15 à 20%, sa durée de 4 ans maximum et aucun apport calorique n'est dû à 1 'écran.  A traditional device, composed of a thermal screen on the ceiling made of a polyane film or of an aluminized film has the disadvantage of being closed at night, open during the day, the gain in loss is 15 to 20%, its duration of 4 years maximum and no caloric intake is due to 1 screen.

Le dispositif de la présente invention est lui fixe, il diminue les déperditions de plus de 60%, apporte soit des calories soit des frigories, et sert de capteur solaire. The device of the present invention is fixed to it, it reduces the losses by more than 60%, provides either calories or frigories, and serves as a solar collector.

Pour se faire, des tubes en polypropylène, aluminium, cuivre ou tout autre matériau à conductibilité importante, sont disposés le long des parois verticales et horizontales (plafonds) et forment une double paroi intérieure à l'enveloppe du bâtiment, telle une cage. Ces tubes ont un écartement variable en fonction de la température de l'eau que l'on y fait circuler, écartement compris entre 0 et 0,30 mètre. La température de l'eau les traversant est comprise entre 10 C et 35"C.  To do this, polypropylene, aluminum, copper or any other material with high conductivity are placed along the vertical and horizontal walls (ceilings) and form a double wall inside the building envelope, like a cage. These tubes have a variable spacing depending on the temperature of the water that is circulated therein, spacing between 0 and 0.30 meters. The temperature of the water passing through them is between 10 ° C. and 35 "C.

Le fonctionnement de l'installation se fait à partir d'un bassin de grande capacité variant en fonction du volume d'eau circulant dans les tubes. The operation of the installation is done from a large capacity basin varying according to the volume of water circulating in the tubes.

L'eau du bassin est soit chauffée à l'aide d'une source calorique quelconque : brûleur submergé, chaudière basse température, pompe à chaleur, soit chauffée par les eaux traversant les tubes quand ceux-ci sont soumis à 1 'ensoleil- lement
L'eau de ce bassin est pompée, puis envoyée dans les tubes placés en parois : ces tubes réagissent alors de deux façons : soit en apport calorique à la construction, soit en climatisation de l'installation.The pond water is either heated using any caloric source: submerged burner, low temperature boiler, heat pump, or heated by the water passing through the tubes when they are subjected to sunlight.
The water from this basin is pumped, then sent into the tubes placed on the walls: these tubes then react in two ways: either as a caloric contribution to the construction, or as air conditioning of the installation.

Quand l'installation réagit en apport calorique, l'eau qui circule dans les tubes, plus chaude que l'air ambiant du bâtiment, provoque un rayonnement créant un écran thermique entre les intervalles iaissés par les tubes : la résistance thermique de cet écran agit comme un isolant et une partie de l'émission calorique des tubes est récupérée pour chauffer l'air ambiant. When the installation reacts with caloric intake, the water circulating in the tubes, hotter than the ambient air in the building, causes radiation creating a thermal screen between the intervals left by the tubes: the thermal resistance of this screen acts as an insulator and part of the heat emission from the tubes is recovered to heat the ambient air.

'Inversement, quand les tubes agissent en climatisation du local, 1' eau de circulation dans les tubes est plus froide que 1' atmosphère extérieure : cette eau de circulation se charge en calories au contact d'un air ambiant plus chaud qu'elle, ce qui entraîne une chute de cette température ambiante et qui, de plus, augmente le taux d 'hygrométrie. Conversely, when the tubes act in room air conditioning, the circulation water in the tubes is cooler than the external atmosphere: this circulation water is loaded with calories on contact with ambient air that is warmer than it, which causes a drop in this ambient temperature and which, moreover, increases the humidity rate.

Dans les serres verre ou plastique, ces tubes captent le rayonnement solaire en plus des calories ambiantes' ce qui entraîne le réchauffement de l'eau de circulation, eau qui est ramenée dans le bassin d'où elle provient, bassin qui accumule l'énergie solaire récupérée par les tubes. In glass or plastic greenhouses, these tubes capture solar radiation in addition to the ambient calories' which leads to the heating of the circulation water, water which is brought back into the basin from which it comes, basin which accumulates energy solar recovered by the tubes.

- ta figure 1 et 2 représentent le dispositif selon l'invention.- Your Figure 1 and 2 show the device according to the invention.

- La figure 3 représente une coupe caractérisée des tubes formant l'écran thermique. - Figure 3 shows a characterized section of the tubes forming the heat shield.

Ce dispositif est particulièrement destiné au chauffage et à la cli matisation des serres, mais le principe peut s'appliquer à un bâtiment quel connue.  This device is particularly intended for heating and air conditioning of greenhouses, but the principle can be applied to a known building.
