Abstract

The system uses an underfloow masonry heat storage (2) installation to retain heat gathered from solar collectors (1). The working fluid used is air which is heated as it passes through a roof mounted solar collector (1). A fan (5) moves the hot air from the collector through the storage (2) and thence back to the collector. The heat is returned to the interior (3) of the house by conduction through the floor (4). Alternative heating arrangements for the heat store are an electrically heated air convection limit or an electric resistance heating element which heats the storage medium directly by conduction.

Description

PLANCHER CHAUFFANT A PUISSANCE MODULABLE ASSOCIE A UN STOCK
DE CHALEUR, AVEC DE L'-AIR COMME FLUIDE CALOPORTEUR.MODULAR POWER HEATING FLOOR ASSOCIATED WITH A STOCK
OF HEAT, WITH AIR AS HEAT FLUID.

La présente invention concerne le chauffage d'un b ti- ruent par le plancher avec une source de chaleur intermittente, telle que des capteurs solaires â air ou l'électricité des heure creuses. The present invention relates to the heating of a building by the floor with an intermittent heat source, such as solar air collectors or off-peak electricity.

Jusqu'alors un chauffage solaire à air comprenait, en principe, des capteurs à air, un stock de chaleur (souvent un container rempli de galets), et des bouches d'aération pour amener l'air chaud des galets à l'intérieur de la maison. Ce type de chauffage présente quatre inconvénients a) I1 peut arriver que les galets soient enrobés de microorganismes qui multiplient grâce à l'humidité et aux graisses contenues dans l'air de la maison qui passe à travers le stock.Until then, solar air heating included, in principle, air collectors, a heat store (often a container filled with pebbles), and air vents to bring the hot air from the pebbles inside the House. This type of heating has four drawbacks a) I1 can happen that the rollers are coated with microorganisms which multiply thanks to the humidity and grease contained in the air of the house which passes through the stock.

Ceci provoque des odeurs désagréables et une perte de rendement thermique.This causes unpleasant odors and a loss of thermal efficiency.

b) Pour profiter de toute la chaleur disponible dans le stock, on doit travailler avec de l'air moins chaud que dans les chauffages à air pulsé classiques, ce qui nécessite un débit plus important avec plus de bruit et une sensation de fro-id à cause du mouvement de l'air.b) To take advantage of all the heat available in the stock, we must work with air that is less hot than in conventional forced air heaters, which requires a higher flow rate with more noise and a feeling of cold. because of the air movement.

c) Un stock assez important pour assurer une grande partie du chauffage est encombrant, et constitue une perte de volume à l'intérieur du bâtiment.c) A stock large enough to provide a large part of the heating is bulky, and constitutes a loss of volume inside the building.

d) Une stratification thermique de l'air de la maison s'établit; il fait souvent trop frais au niveau du sol et trop chaud à côté du plafond.d) A thermal stratification of the air in the house is established; it is often too cool at ground level and too hot near the ceiling.

Le système présenté ici permet d'éviter ces inconvénients. I1 est caractérisé par un stock disposé sous une grande partie de la maison, qui travaille en circuit fermé avec la source de chaleur et un plancher chauffant. The system presented here makes it possible to avoid these drawbacks. It is characterized by a stock placed under a large part of the house, which works in a closed circuit with the heat source and a heated floor.

Le stock peut être soit des galets, soit des éléments de maçonnerie lourd tels que des blocs de béton, soit des containers remplis d'un produit à forte inertie thermique. I1 est isolé fortement en dessous et sur les côtés, et faiblement par dessus. The stock can be either pebbles, or heavy masonry elements such as concrete blocks, or containers filled with a product with high thermal inertia. It is insulated strongly below and on the sides, and weakly above.

Le plancher chauffant comprend des canalisaations d'air qui permettent de le ventiler avec l'air chaud du stock ; les canalisations peuvent être soit des tubes noyés dans le ciment, soit l'espace entre l'isolation haute du stock et une plaque ondulée qui sert comme coffrage perdu pour le ciment du plan cher, soit des éléments préfabriqués qui font partie du plancher.The underfloor heating includes air ducts which allow it to be ventilated with the hot air from the stock; the pipes can be either tubes embedded in the cement, or the space between the upper insulation of the stock and a corrugated plate which serves as lost formwork for the cement of the expensive plan, or prefabricated elements which form part of the floor.

La source de chaleur peut être soit des capteurs solaires à air, soit un ventilo-convecteur électrique, soit une résistance électrique en contact direct avec le stock. The heat source can be either solar air collectors, or an electric fan coil, or an electrical resistance in direct contact with the stock.

La figure 1 représente un système classique de chauffage solaire à air, et la figure 2 le nouveau système en variante solaire. Figure 1 shows a conventional solar air heating system, and Figure 2 the new solar variant system.

Dans un système classique (1), l'air chauffé dans les capteurs (1) pendant l'ensoleillement est envoyé dans le haut du stock (2). Il cède sa chaleur aux galets et sort plus frais du bas du stock pour rentrer de nouveau dans les capteurs. Pendant la restitution de la chaleur à la maison (3), l'air sort chaud du haut du stock, passe à travers la maison et rentre moins chaud dans le bas du stock. In a conventional system (1), the air heated in the collectors (1) during the sunshine is sent to the top of the stock (2). It gives up its heat to the pebbles and comes out cooler from the bottom of the stock to re-enter the sensors. During the return of heat to the house (3), the air comes out hot from the top of the stock, passes through the house and returns less warm at the bottom of the stock.

Les figures (2) et (3) montre une variante du nouveau système : pendant le stockage l'air chaud des capteurs solaires (1) entre dans un côté (7) du stock (2) et sort plus frais de l'autre côté (8) pour regagner les capteurs. La chaleur est restituée en permanence par conduction à travers le plancher (4) à une puissance minimale, et quand une puissance plus importante est nécessaire, un ventilateur (5) retire l'air du eoté chaud (7) du stock (déstockage), pour le souffler danbe conduit (9) qui l'amène au ride oûs le plancher. I1 cède sua chaleur au plancher à travers lanplaque ondulée(0et ressort plus frais pour rentrer directement de l'autre côté par le conduit commun (8). Ainsi le plancher se chauffe, et plus de chaleur passe dans la maison (3) par convection et par rayonnement à la surface du plancher. Figures (2) and (3) show a variant of the new system: during storage the hot air from the solar collectors (1) enters one side (7) of the stock (2) and leaves cooler on the other side (8) to return to the sensors. The heat is constantly restored by conduction through the floor (4) at a minimum power, and when a higher power is required, a fan (5) withdraws the air from the hot side (7) from the stock (destocking), to blow it into the duct (9) which brings it to the wrinkle or the floor. It gives off heat to the floor through the corrugated plate (0 and comes out cooler to enter directly on the other side through the common duct (8). Thus the floor heats up, and more heat passes into the house (3) by convection and by radiation to the floor surface.

Ce système de plancher chauffant avec stockage de chaleur peut servir pour toute sorte de bâtiment bien isolé dont l'utilisation pricipale est au niveau du rez-de-chaussée, et qui dispose d'une source de chaleur intermittente, d'une période de l'ordre d'un jour maximum. Il serait particulièrement intéressant pour des maisons individuelles dont les pièces principales se trouvent au rez-de-chaussée, et pour des entrepôts qui ont besoin d'une température stable et pas trop élevée.  This floor heating system with heat storage can be used for any kind of well insulated building whose main use is at the ground floor level, and which has an intermittent heat source, a period of l 'order of a day maximum. It would be particularly interesting for individual houses whose main rooms are on the ground floor, and for warehouses which need a stable temperature and not too high.
