Abstract

The solar heating system with heat collectors designed for rapid heating up, uses two transparent domes, one dome inside the other for each heat collector. Mounted at one side of the base of the heat collector is a vertical reflector so that further rays of the sun are reflected inside besides those passing directly through the two domes. The two domes are mounted on an insulation layer enclosed by the base sheet, and this layer has recesses holding the water circulating coils forming the heat exchanger. One design uses a cellular heat collector containing a product whose fusion point is between the temperature limits of the system, for a high heat exchange.

Description

La présente invention concerne les nstallations du te Capteur solaire à échangeur thermique associé à un accumulateur d'énergie permettant l'obtention d'eau chaude. The present invention relates to the installations of the solar collector with heat exchanger associated with an energy accumulator enabling hot water to be obtained.

Dans les dispositifs de ce genre, les capteurs ont un mauvais rendement dû au manque de concentration du rayonnement et à l'inclinaison du soleil matin et soir ; les réserves calorifiques sont de simples réservoirs isolés d'eau chaude et dans le cas dhauffage celui-ci devient rapidement inefficace pendant les periodes de ciel couvert. In devices of this kind, the sensors have a poor performance due to the lack of concentration of the radiation and the inclination of the sun morning and evening; the calorific reserves are simple isolated tanks of hot water and in the case of heating it becomes quickly ineffective during periods of overcast sky.

Le capteur solaire à deux coupoles elliptiques en verre ou en plexiglas permet une montée rapide en température de l'échangeur thermique en concentrant le rayonnement vers celui-ci ; la concentration est amé- liorée par le réfléchissement du déflecteur vers les coupoles. Ce système améliore le rendement en durée (matin et soir) et en quantité horaire car Q = m C (s - e) (Q = quantité de calories captées, m = masse chauffée, C = indice calorifique du produit chauffé, #s = = température de sortie de l'échangeur et #e = température d'entrée).  The solar collector with two elliptical domes in glass or plexiglass allows a rapid rise in temperature of the heat exchanger by concentrating the radiation towards it; the concentration is improved by the reflection of the deflector towards the domes. This system improves the yield in duration (morning and evening) and in hourly quantity because Q = m C (s - e) (Q = quantity of calories captured, m = heated mass, C = calorific index of the heated product, #s = = exchanger outlet temperature and #e = inlet temperature).

Plus L'écart "#s - #e" est important, plus Q est important. Les pertes par réfléchissement sont minimes à cause de l'isolation et du système de la double paroi (deux coupoles). The larger the difference "#s - #e", the larger Q is. Reflection losses are minimal due to the insulation and the double wall system (two domes).

Cet ensemble performant est associé à un accumulateur à alvéoles permettant de stocker une énergie calorifique importante en utilisant le principe de la chaleur de "fusion-solidification" d'un produit dont le point de changement d'état est compris dans l'intervalle des températu- res d'utilisation. La formule utilisée est Q = m1 C1 (t - Pi) + m2 Cf ( Q = quantité de calories stockées, m1 = masse du corps chauffé, C1 = indice calorifique de m1, #t = température terminale de l'ensemble, #i = = température initiale, m2 = masse du produit contenu dans les al#é- oles, Cf = chaleur de fusion de m2 par exemple 35000 calories / Kg de paraffine).L'emploi de la paraffine permet une régulation supérieure à 50 degrés Celcius (520 C) qui est une température utilisable pour l'eau chaude domestique et le chauffage central à eau. En fonction de la situa- tion géographique et de l'emploi les capteurs solaires peuvent être coupliés ainsi que les accumulateurs à alvéoles. This powerful assembly is associated with a cell accumulator making it possible to store a significant calorific energy by using the principle of the heat of "fusion-solidification" of a product whose point of change of state is included / understood in the interval of the temperatures. - res of use. The formula used is Q = m1 C1 (t - Pi) + m2 Cf (Q = quantity of calories stored, m1 = mass of the heated body, C1 = calorific index of m1, #t = terminal temperature of the set, #i = = initial temperature, m2 = mass of the product contained in the al # schools, Cf = heat of fusion of m2 for example 35000 calories / Kg of paraffin) .The use of paraffin allows a regulation higher than 50 degrees Celcius (520 C) which is a temperature usable for domestic hot water and central water heating. Depending on the geographic location and the use, the solar collectors can be coupled together with the cell accumulators.

Le dessin pour l'abrégé numéro 1/2 est une coupe figurative du capteur solaire à deux"coupoles elliptiques" et déflecteur . Tel qu'il est représenté le capteur solaire comprend un support 1 dans lequel repose un échangeur thermique 2 sur un isolant 3, l'ensemble étant recouvert de deux coupoles, une extérieure 4 et une intérieure 5, fabriquées en verre ou en plexiglas ; un déflecteur 6 réfléchit les rayons solaires sur les coupoles.

Le dessin pour l'abrégé numéro 2 / 2 est une coupe schematique de l'accumulateur à alvéoles dans le cas chauffage et eau chaude domestique. Tel qu'il est représenté l'accumulateur comprend un corps 1 dans lequel sont installés des supports 2 qui maintiennent des alvéoles 3 remplies de paraffine et un réservoir d'eau chaude domestique 7 ; un fond 4 et un devant 5 sont fixés par des boulons 9 sur des joints R. The drawing for abstract number 2/2 is a schematic section of the cell accumulator in the case of heating and domestic hot water. As shown, the accumulator comprises a body 1 in which supports 2 are installed which hold cells 3 filled with paraffin and a domestic hot water tank 7; a bottom 4 and a front 5 are fixed by bolts 9 on seals R.

L'ensemble qui est isolé par du "feutre laine de verre" 6 comporte un système "sécurité-purge" 10.The assembly which is insulated by "glass wool felt" 6 comprises a "safety-purge" system 10.

Parmi les applications les plus intéressantes on peut citer la fourniture d'eau chaude et le chauffage central par fluide.  Among the most interesting applications one can cite the supply of hot water and central heating by fluid.
