Description
Procédé de climatisation de locaux comPortant une Paroi vitrée de arande surface. Air conditioning process for premises with a glass wall of large surface.
L'invention concerne un procédé de climatisation de locaux comportant une paroi vitrée de grande surface, telle qu'une véranda, du type dans lequel, de préférence, la paroi vitrée est double de manière à former une lame d'air.The invention relates to a method of air conditioning of premises comprising a large glazed wall, such as a veranda, of the type in which, preferably, the glazed wall is double so as to form an air space.
Les parois vitrées de grande surface, telles que des vérandas, des verrières, des murs rideaux, des bow-windows ou des parois de serres offrent les avantages d'une grande luminosité et d'apports calorifiques gratuits par l'effet de serre dû au rayonnement solaire. Cependant, ces parois vitrées constituent des sources chaudes localisées excessives qui rendent leur voisinage impraticable, en particulier lors des journées ensoleillées.Large-area glass walls, such as verandas, canopies, curtain walls, bow windows or greenhouse walls offer the advantages of high brightness and free calorific contributions due to the greenhouse effect due to solar radiation. However, these glass walls constitute excessive localized hot springs which make their vicinity impracticable, in particular on sunny days.
Pour limiter les apports solaires, on peut interposer un élément formant protection tel qu'un store, on peut assurer une ventilation par extraction mécanique ou naturelle de l'air chaud ou encore installer une climatisation.To limit solar gain, you can interpose a protective element such as a blind, you can provide ventilation by mechanical or natural extraction of hot air or install air conditioning.
Cependant, ces solutions bien connues ne sont pas totalement satisfaisantes dans la mesure où elles sont pour certaines insuffisantes et pour les autres trop onéreuses. However, these well-known solutions are not entirely satisfactory insofar as they are for some insufficient and for others too expensive.
Afin d'améliorer la performance thermique des parois vitrées, il est connu de rendre celles-ci doubles afin de ménager entre les deux vitres constitutives une lame d'air dans laquelle on interpose des surfaces réfléchissantes parallèles du type store-vénitien. Cette disposition a pour but principal de réaliser des économies de chauffage mais ne suffit pas à éliminer les effets de surchauffe évoqués précédemment.In order to improve the thermal performance of the glazed walls, it is known to make them double in order to provide between the two constituent panes an air space in which are interposed parallel reflecting surfaces of the venetian-blind type. The main purpose of this arrangement is to achieve savings in heating, but is not sufficient to eliminate the overheating effects mentioned above.
De plus, aucune de ces solutions ne permet de profiter des apports calorifiques gratuits occasionnés par l'effet de serre.In addition, none of these solutions allows you to take advantage of the free calorific contributions caused by the greenhouse effect.
La présente invention vise à supprimer ces inconvénients grâce à une élimination et une récupération de ces calories.The present invention aims to eliminate these drawbacks by eliminating and recovering these calories.
A cet effet, l'invention consiste en un procédé de climatisation d'un local comportant une paroi vitrée, telle qu'une véranda, caractérisée en ce que l'air dans le local est extrait de manière mécanique et est circulé au moyen d'un extracteur mécanique dans un dispositif échangeur de chaleur constitué d'un élément de stockage et d'un élément échangeur de chaleur, ledit dispositif stockant et redistribuant les calories par conduction.To this end, the invention consists of a method of air conditioning a room comprising a glazed wall, such as a veranda, characterized in that the air in the room is extracted mechanically and is circulated by means of a mechanical extractor in a heat exchanger device consisting of a storage element and a heat exchanger element, said device storing and redistributing the calories by conduction.
Avec le procédé selon l'invention, les calories formées par le rayonnement solaire sont évacuées par l'extraction mécanique, de sorte que les points chauds créés par leur accumulation sont supprimés mais, de plus, ces calories sont stockées et récupérables.With the method according to the invention, the calories formed by solar radiation are removed by mechanical extraction, so that the hot spots created by their accumulation are eliminated but, moreover, these calories are stored and recoverable.
Le dispositif échangeur de chaleur comprend un élément de stockage constitué par une masse d'inertie telle que du béton, des galets, du sable, de l'eau, un corps céramique, ou autres matériaux équivalents, dans lequel circule un élément échangeur de chaleur constitué par un faisceau de gaines en matière imputrescible et étanche assurant la circulation de l'air extrait du local.The heat exchanger device comprises a storage element constituted by a mass of inertia such as concrete, pebbles, sand, water, a ceramic body, or other equivalent materials, in which a heat exchanger element circulates. constituted by a bundle of sheaths made of rot-proof and waterproof material ensuring the circulation of the air extracted from the room.
L'air circulant dans le dispositif échangeur de chaleur est soumis à un transfert par conduction de calories ou de frigories du fait de la différence de température entre l'air extrait du local et circulé dans l'élément échangeur de chaleur et l'élément de stockage.The air circulating in the heat exchanger device is subjected to a transfer by conduction of calories or frigories because of the temperature difference between the air extracted from the room and circulated in the heat exchanger element and the storage.
Avantageusement, l'élément de stockage est situé sous le local et est thermiquement isolé de l'extérieur mais il peut également se trouver à l'extérieur dans un élément garantissant la différence de température nécessaire au transfert de chaleur.Advantageously, the storage element is located under the room and is thermally isolated from the outside, but it can also be outside in an element guaranteeing the temperature difference necessary for the heat transfer.
Selon un mode de réalisation préféré du procédé de l'invention, on fait circuler l'air de haut en bas å travers une lame dtair constituée par une paroi vitrée double avant de l'introduire dans le dispositif échangeur de chaleur.According to a preferred embodiment of the method of the invention, the air is circulated from top to bottom through an air blade formed by a double glazed wall before introducing it into the heat exchanger device.
Avantageusement, on dispose dans cette lame d'air des lames parallèles, de préférence escamotables et orientables du type store vénitien. Ainsi, l'air extrait du local peut également se charger des calories piégées par les lames du store.Advantageously, there are in this air space parallel blades, preferably retractable and orientable of the Venetian blind type. Thus, the air extracted from the room can also take care of the calories trapped by the blind blades.
Avantageusement, on commande l'extracteur mécanique par des moyens thermostatiques, de préférence celui-ci étant un ventilateur.Advantageously, the mechanical extractor is controlled by thermostatic means, preferably the latter being a fan.
L'invention sera bien comprise à la lecture de la description suivante faite en se référant au dessin annexé dans lequel
la figure 1 est un schéma d'un local équipé d'un
dispositif échangeur de chaleur selon un mode de
réalisation préféré du procédé de l'invention,
la figure 2 est analogue à la figure 1, pour le
régime d'été,
la figure 3 est analogue aux figures 1 et 2, pour
le régime d'hiver et de mi-saison en journée
ensoleillée, et
la figure 4 est analogue aux figures 1, 2 et 3,
pour le régime d'hiver et de mi-saison de nuit.The invention will be clearly understood on reading the following description made with reference to the accompanying drawing in which
Figure 1 is a diagram of a room equipped with a
heat exchanger device according to a mode of
preferred implementation of the method of the invention,
Figure 2 is similar to Figure 1, for the
summer diet,
Figure 3 is similar to Figures 1 and 2, for
the winter and mid-season diet during the day
sunny, and
FIG. 4 is similar to FIGS. 1, 2 and 3,
for the winter and mid-season night regime.
Le dessin représente un local 1 comprenant une véranda fermée par une paroi vitrée double 2 sur la façade sud formant une lame d'air 3 équipée d'un store à lames orientables 4.The drawing represents a room 1 comprising a veranda closed by a double glazed wall 2 on the south facade forming an air space 3 equipped with a blind with adjustable slats 4.
La lame d'air 3 est ouverte à sa partie supérieure et sa partie inférieure débouche dans l'élément échangeur de chaleur constitué par un réseau de gaines 5 traversant un élément de stockage isolé 6 en sous-sol ainsi qu'un élément de stockage non isolé 7 situé en sous-sol à l'extérieur et de préférence dans la zone ombrée au nord de l'habitation, l'ensemble formant un dispositif échangeur de chaleur. La sortie du réseau de gaines 5 est raccordée, par l'intermédiaire d'un système de ventilation mécanique 8, à une bouche de soufflage 9 débouchant dans le local 1.The air gap 3 is open at its upper part and its lower part opens into the heat exchanger element constituted by a network of ducts 5 passing through an insulated storage element 6 in the basement as well as a non-storage element. insulated 7 located in the basement outside and preferably in the shaded area north of the house, the assembly forming a heat exchanger device. The outlet of the duct network 5 is connected, by means of a mechanical ventilation system 8, to a blowing opening 9 opening into the room 1.
En régime d'été (figure 2), la ventilation 8 produit un courant d'air qui, après avoir traversé le local 1, arrive à l'ouverture supérieure de la lame d'air 3 de la paroi vitrée double. L'air qui se trouve ici à l'endroit le plus chaud, est forcé vers le bas à travers cette lame d'air 3.In summer mode (Figure 2), ventilation 8 produces a current of air which, after passing through room 1, arrives at the upper opening of the air gap 3 of the double glazed wall. The air which is located here at the hottest place, is forced downward through this air gap 3.
L'air récupère au passage les calories piégées par les lames 4 du store. La double paroi joue ainsi le rôle de capteur solaire tout en assurant une protection limitant les sources d'apport de chaleur grâce au store. The air recovers the calories trapped by the blades 4 of the blind. The double wall thus plays the role of solar collector while ensuring protection limiting the sources of heat input thanks to the blind.
L'air circule dans le réseau de gaines 5 et cède par conduction sa chaleur à l'élément de stockage 6 qui s'échauffe progressivement.The air circulates in the duct network 5 and transfers its heat by conduction to the storage element 6 which gradually heats up.
Avant d'hêtre réintroduit dans le local, l'air est circulé dans le réseau de gaines extérieur et l'élément de stockage 7 non isolé, ici le sous-sol, où il se rafraîchit pour tendre à la température dudit sous-sol.Before being reintroduced into the room, the air is circulated in the external duct network and the non-insulated storage element 7, here the basement, where it cools to tend to the temperature of said basement.
En période froide (hiver ou mi-saison), pour une journée de faible ensoleillement d'hiver (figure 3), l'air chaud suit le même parcourt que dans la figure 2 mais ne passe plus dans le réseau de gaines extérieur, la température du soussol étant trop fraîche et le besoin en frigories étant moindre.In cold periods (winter or mid-season), for a day of low winter sunshine (Figure 3), the hot air follows the same path as in Figure 2 but no longer passes through the outdoor duct network, the temperature of the basement being too cool and the need for refrigeration being less.
Le transfert des calories lors du passage dans l'élément de stockage 6, par le réseau de gaines 5, se fait en sens inverse, l'air se réchauffe et les calories stockées pendant l'été et les journées ensoleillées de mi-saison sont alors récupérées ce qui permet de limiter les besoins en chauffage.The transfer of calories when passing through the storage element 6, through the duct network 5, is done in the opposite direction, the air heats up and the calories stored during the summer and the sunny days of mid-season are then recovered which limits the heating requirements.
Pendant la nuit (figure 4), les lames de store 4 sont en position fermée ce qui limite les radiations nocturnes, sources principales de déperdition. During the night (FIG. 4), the blind slats 4 are in the closed position, which limits the night radiations, the main sources of loss.
