Abstract

Device for storing-exchanging heat energy intended to save on energy, investment or running costs in all the cases in which the temperature required in an enclosure is different from the outside ambient temperature in the range -30 DEG C, +60 DEG C (temperature in the enclosure). The device is characterised by a high coefficient of energy stored/volume, conferred by a latent heat storage means, by passive exchanges between stock and internal volume of the enclosure by natural convection which is adjusted by mechanically obstructing the convective path. The device according to the invention is particularly intended for the production of heat or of cold having considerable asynchronism between the "Needs" histogram and the "Energy" histogram.

Description

La présente invention concerne l'adjonetion d'un stockage calorifique à chaleur latente, situé loin de l'enveloppe et dont la surface verticale est dimensionnée de façon à assurer à elle seule les échanges par convection naturelle nécessaires aux plus grands besoins de lthistogramme du fonctionnement d'un process produisant de la chaleur ou du froid. The present invention relates to the addition of a latent heat calorific storage, located far from the envelope and whose vertical surface is dimensioned so as to ensure alone the exchanges by natural convection necessary for the greatest needs of the operating histogram. of a process producing heat or cold.

Les systèmes actuels à stockage calorifique se rapprochant le plus du système proposé, font appel à une masse thermique solide caractérisée par un coefficient de conduction faible et nécessitant souvent l'action d'une ventilation forcée. The current heat storage systems that come closest to the proposed system, use a solid thermal mass characterized by a low coefficient of conduction and often requiring the action of forced ventilation.

Le rôle du stockage est très différent selon le type de l'histogramme "énergie" et de l'histogramme "besoins": lthistogramme "énergie" est le plus souvent de période quotidienne (double tarification E.D.F., alternance journuit de lténergie solaire...). L'histogramme "besoins" est très variable (besoins peu variables dans un réfrigérateur, de période quotidienne pour la climatisation du secteur tertiaire, de même période mais d'amplitude plus faible pour le chauffage dans le résidentiel, de période très longue de l'ordre du trimestre pour la conservation inter-récolte des produits vivriers dans les pays tropi- caux...). The role of storage is very different depending on the type of the "energy" histogram and the "needs" histogram: the "energy" histogram is most often of daily period (double EDF pricing, daily alternation of solar energy ... ). The histogram "needs" is very variable (little variable needs in a refrigerator, of daily period for air conditioning in the tertiary sector, of the same period but of lower amplitude for heating in the residential, of very long period of the quarter order for inter-harvest conservation of food products in tropical countries ...).

La juxtaposition des deux périodes met en évidence dans la plupart des cas soit un surinvestissement, soit un surcoût d'exploitation. The juxtaposition of the two periods highlights in most cases either an overinvestment or an additional operating cost.

Le dispositif selon l'invention permet de remédier à la majorité des inconvénients constatés dans les systèmes actuels. I1 comporte en effet un réservoir I contenant le produit changeant de phase liquide-solide à la température re requise pour le stock. Ce réservoir reçoit de l'éner- gie positive ou négative (chaud ou froid) en provenance du process 2 au moment le plus favorable de lthistogramme "énergie". Le réservoir I situé au milieu de l'enceinte à conditionner 3 possède une surface verticale dimensionnée pour assurer les échanges par convection naturelle nécessaires au moment du plus grand besoin de l'histogramme "besoin".Le réglage de la température de ltenceinte se fait par l'ouverture progressive des ouïes 4 situées sur la double paroi 5 et obstruant ainsi plus ou moins le trajet du mouvement de convection. L'entrée du circuit convectif de la double paroi peut etre obstruée mécaniquement lors des ouvertures de porte pour les systèmes destinés à produire du froid. Le choix de la température de fusion du stock permet également d'autoréguler l'hygrométrie du local à conditionner. La diminution de la consommation est surtout liée à la position du stock au centre de l'enceinte, loin de ltenveloppe mais aussi à la diminution de l'écart de température entre stock et température utile de l'enceinte, améliorant ainsi la valeur du coefficient de performance du process dans le cas de machines trithermes ou plus. The device according to the invention overcomes the majority of the drawbacks observed in current systems. I1 indeed comprises a reservoir I containing the product changing liquid-solid phase at the temperature re required for the stock. This tank receives positive or negative energy (hot or cold) from process 2 at the most favorable moment of the "energy" histogram. The tank I located in the middle of the enclosure to be conditioned 3 has a vertical surface dimensioned to ensure the exchanges by natural convection necessary at the time of greatest need of the "need" histogram. The temperature of the enclosure is adjusted by the progressive opening of the vents 4 located on the double wall 5 and thus more or less obstructing the path of the convection movement. The entry of the convective circuit of the double wall can be obstructed mechanically during door openings for systems intended to produce cold. The choice of stock melting temperature also allows self-regulation of the humidity of the room to be conditioned. The decrease in consumption is mainly linked to the position of the stock in the center of the enclosure, far from the envelope but also to the decrease in the temperature difference between stock and useful temperature of the enclosure, thus improving the value of the coefficient of process performance in the case of trithermal machines or more.

Le dispositif objet de l'invention s'applique dans tous les cas où la température requise à l'intérieur d'une enceinte est différente de la température ambiante extérieure.  The device which is the subject of the invention applies in all cases where the temperature required inside an enclosure is different from the outside ambient temperature.
