Description

451 215 kontaktvärmeöverföring mellan kroppen och pannans hetvat- tendel. 451 215 contact heat transfer between the body and the hot water part of the boiler.

I den för närvarande mest föredragna utföringsformen är värmeackumulatorkroppen anordnad att uppvärmas till nämnda höga temperatur med användning av nattelenergi.In the presently most preferred embodiment, the heat accumulator body is arranged to be heated to said high temperature using night energy.

I en utföringsform omfattar kontaktvärmeöverföringsan- ordningen ett mellan en kontaktyta hos kroppen och en värmeupptagande yta hos hetvattendelen till operativ posi- tion införbart element.In one embodiment, the contact heat transfer device comprises an element which can be inserted into the operative position between a contact surface of the body and a heat-absorbing surface of the hot water part.

I en annan utföringsform är åtminstone en värmeuppta- gande yta hos hetvattendelen omställbar till respektive från operativ värmeöverföringsposition relativt ackumu- latortorkroppen.In another embodiment, at least one heat-absorbing surface of the hot water part is adjustable to or from the operative heat transfer position relative to the accumulator dryer body.

I den senare utföringsformen är lämpligen hetvatten- delens värmeupptagande yta höj- och sänkbar.In the latter embodiment, the heat-absorbing surface of the hot water part is suitably height-adjustable.

En termostatanordning är företrädesvis inrättad att av- känna temperaturen i hetvattendelen och styra värmeöver- föringen mellan ackumulatorkroppen och hetvattendelen.A thermostat device is preferably arranged to sense the temperature in the hot water part and control the heat transfer between the accumulator body and the hot water part.

En lämplig variant av till operativ position mellan kroppens kontaktyta och hetvattendelens värmeyta införbart element omfattar en första värmeledande del, exempelvis av koppar, och en andra värmeisolerande del, exempelvis av keramik, så inrättade att var och en av delarna kan föras till direktkontakt med nämnda ytor.A suitable variant of elements insertable into the operative position between the contact surface of the body and the heating surface of the hot water part comprises a first heat-conducting part, for example of copper, and a second heat-insulating part, for example of ceramic, arranged so that each of the parts can be brought into direct contact with said surfaces. .

I en ytterligare utföringsform är åtminstone den ena av nämnda ytor en plan yta, med vilken det kontaktvärmeöver- förande elementet är anordnat att göra kilingrepp.In a further embodiment, at least one of said surfaces is a flat surface, with which the contact heat-transmitting element is arranged to make wedge engagement.

I syfte att ytterligare belysa uppfinningstanken kommer nu nägra utföringsformer av uppfinningen att avhandlas med hänvisning till bifogade ritningar, där Fig. 1 schematiskt visar principen vid kontaktvärmeöver- föring i en "horisontellt" och en vertikalt arbetan- de kontaktvärmeanordning, och Fig. 2 visar en "horisontell" variant med kilformigt kon- taktvärmeöverföringselement.In order to further elucidate the idea of the invention, some embodiments of the invention will now be discussed with reference to the accompanying drawings, in which Fig. 1 schematically shows the principle of contact heat transfer in a "horizontal" and a vertically operating contact heating device, and Fig. 2 shows a "horizontal" variant with wedge-shaped contact heat transfer element.

Den med hänvisningssiffran l0 i Fig. 1 visade pannan är en elektrisk panna. I de kända varianterna är panntypen av det slag där en elektrisk värmepatron ll ombesörjer upp- 451 215 värmning av vattnet i hetvatten/radiatorsystemet 12. Led- ningar till respektive från radiatorer har betecknats med 13 och 14. Tappvarmvattensystemet 15 kan få sin uppvärmning från det omgivande systemet 12 eller ha en separat värme- patron (ej visad). Ledningar till respektive från varmvat- tenbehållaren 15 har markerats med siffrorna 16 och 17.The boiler shown by the reference numeral 10 in Fig. 1 is an electric boiler. In the known variants, the boiler type is of the type in which an electric heating cartridge 11 provides heating of the water in the hot water / radiator system 12. Pipes to and from radiators, respectively, have been denoted by 13 and 14. The domestic hot water system 15 can be heated from the surrounding system 12 or have a separate heating cartridge (not shown). Pipes to and from the hot water tank 15 have been marked with the numbers 16 and 17.

Pannan i Fig. 1 har i sin nedre ände en värmeackumula- torkropp 18 av ett material med hög värmekapacitet, exem- pelvis gjutjärn. Den effektiva värmekapaciteten hos en kropp av storleksordningen 30x30x3O cm kan vid en tempera- tur av cirka 4000 C uppskattas till mellan 20.000 - 100.000 kcal, beroende på isolering och järntyp. Den övre siffran svarar väl mot energibehovet (120 kWh) för en normalvilla en extrem vinterdag.The boiler in Fig. 1 has at its lower end a heat accumulator body 18 of a material with a high heat capacity, for example cast iron. The effective heat capacity of a body of the order of 30x30x30 cm can be estimated at a temperature of about 4000 C to between 20,000 - 100,000 kcal, depending on insulation and iron type. The upper figure corresponds well to the energy requirement (120 kWh) for a normal villa on an extreme winter day.

En elektrisk värmeslinga 19 i form av en elpatron är insatt i ackumulatorkroppen 18 och kan exempelvis ge 15 kW, dvs. mellan klockan 21.00 och 05.00 ger en sådan patron 120 kWh tillförd energi. Patronens 19 till-/frånkoppling styrs lämpligen med en timer 20 och termostat.An electric heating coil 19 in the form of an immersion heater is inserted in the accumulator body 18 and can, for example, provide 15 kW, i.e. between 21.00 and 05.00, such a cartridge provides 120 kWh of supplied energy. The connection / disconnection of the cartridge 19 is suitably controlled by a timer 20 and a thermostat.

Runt värmekroppen 18 finns en kraftig isolering 21, t.ex. av keramiktyp med värmereflekterande ytskikt/belägg- ning.Around the heating element 18 there is a strong insulation 21, e.g. of ceramic type with heat-reflecting surface layer / coating.

Ett i dubbelpilens 22 riktning omställbart element 23, i princip i form av en plan skiva och bestående av en första värmeisolerad del 25, exempelvis av keramik, och en andra värmeledande del 27, exempelvis av koppar, är visat mellan värmekroppens plana ovansida 28 och en väl värme- ledande påbyggnad 29, som är anordnad vid hetvattendelens botten och står i värmeutbytesförhållande med denna. På- byggnaden 25 uppvisar även den en plan värmeöverföringsyta 30.An element 23 which can be adjusted in the direction of the double arrow 22, in principle in the form of a flat plate and consisting of a first heat-insulated part 25, for example of ceramic, and a second heat-conducting part 27, for example of copper, is shown between the flat top 28 and a well heat-conducting extension 29, which is arranged at the bottom of the hot water part and is in heat exchange relationship with it. The superstructure 25 also has a flat heat transfer surface 30.

Elementets 23 omställning i dubbelpilens 22 riktning styrs av en termostat 24, som avkänner temperaturen i het- vattendelen. Denna står på gängse sätt i kommunicerande förbindelse med ett expansionskärl 26. När alltså delen 27 står i kontakt med ytorna 28 och 30 sker transport av värme genom konduktion till vattendelen 12 av pannan 10. I hän- delse av att ackumulatorkroppen 18 ej skulle ha tillräcklig 451 215 kapacitet, finns även en elpatron ll som reserv/tillsats- aggregat.The conversion of the element 23 in the direction of the double arrow 22 is controlled by a thermostat 24, which senses the temperature in the hot water part. This is in the usual way in communicating connection with an expansion vessel 26. Thus, when the part 27 is in contact with the surfaces 28 and 30, heat is transported by conduction to the water part 12 of the boiler 10. In the event that the accumulator body 18 would not have sufficient 451 215 capacity, there is also an immersion heater ll as a spare / additive unit.

I Fig. l är även antytt en variant på kontaktvärmeöver- föringstemat, bestående i en i fjädrar 31 upphängd vatten- del 12, som är rörlig/manöverbar i dubbelpilens 32 rikt- v ning, exempelvis medelst ett arrangemang av elekromagneter (ej visat). 'i Elementet 23 kan utgå i den senare versionen, varvid värmeutbytet sker genom direktkontakt mellan ytorna 28 och 30. Under ackumulatorns uppladdningsperiod får härvid en luftspalt mellan kroppen 18 och påbyggnaden 29 accepteras.Fig. 1 also indicates a variant of the contact heat transfer theme, consisting of a water part 12 suspended in springs 31, which is movable / operable in the direction of the double arrow 32, for example by means of an arrangement of electromagnets (not shown). The element 23 can be removed in the later version, whereby the heat exchange takes place by direct contact between the surfaces 28 and 30. During the charging period of the accumulator, an air gap between the body 18 and the superstructure 29 may be accepted.

Det läckage av värme som uppkommer tillförs i stort sett vattendelen 12, förutsatt att isoleringen hos denna är tillräcklig.The heat leakage that occurs is generally supplied to the water part 12, provided that the insulation thereof is sufficient.

I Fig. 2 visas en ytterligare utföringsform av det kontaktvärmeöverförande elementet 23. Detta är utformat så- som en kil, vars "sneda" yta 32 är anordnad att gå i opera- tivt, värmeöverförande ingrepp med pâbyggnadens 29 kontakt- yta 30, som här är sned och anpassad till ytan 33.Fig. 2 shows a further embodiment of the contact heat transfer element 23. This is designed as a wedge, the "oblique" surface 32 of which is arranged to go into operative, heat transfer engagement with the contact surface 30 of the superstructure 29, as here is oblique and adapted to the surface 33.

I samtliga utföringsformer kommer alltså billig natt- elenergi till användning och ackumuleras i välisolerad lag- ringskropp av kompakt form och som tål jämförelsevis höga temperaturnivàer. Även om specifika utföringsformer behandlats, inses att modifikationer och alternativ givetvis är möjliga inom ramen för bifogade patentkrav. aIn all embodiments, therefore, inexpensive night energy is used and accumulates in a well-insulated storage body of compact shape and which can withstand comparatively high temperature levels. Although specific embodiments have been considered, it will be appreciated that modifications and alternatives are of course possible within the scope of the appended claims. a
