Description

The invention relates to a radiant heater for temperature control of church rooms, especially small churches, chapels or The like, who assign under the seat of pews is, whose heat radiation is essentially against the ground is directed.

Small churches with high quality facilities and more valuable Building fabric, celebration rooms and halls of cemetery chapels can be used with a church full room air heating system Space and cost reasons neither equip nor with reasonable Heating operating costs. Especially with little used Churches, especially if they are listed and have valuable facilities would be heating with egg Full room heating for the rare uses in the rear look at the relatively large tempe caused thereby rature changes that cause considerable damage to the device can lead, not justifiable.

One has therefore tried to solve the problem by a so-called Solve electric chair heater. So far, elec trical infrared radiant heaters used with a Heating element to which a reflector is assigned. The heating element consists of a quartz tube in which a heating coil ver running. These heating elements usually have a nominal output from 4.5 W / cm and develop very high surface areas during operation chentemperaturen. Such high temperature radiators have egg a number of disadvantages. On the one hand there is a high total connected load even with small churches, the Ge chairs with such electric high temperature heating radiators are equipped. Another disadvantage is due to the high surface temperature of the spotlights in the Un danger of falling because it has always been in the past  again with such electric chair heaters with high accidents, for example due to scorched footwear, burned clothing or fire injuries to children. For example, in the in the DE 89 10 492 U1 described electric chair heater with High temperature radiators indicated that the required Protective grille to secure the quartz emitter itself so high heats up even when the protective grille is touched Burns can occur and therefore special measures can be proposed as part of the lattice construction here at least for the grid to lower the temperature get. However, this is the Un described above Fall hazards are by no means eliminated. Beyond acting such spotlights also adversely affect the entire Kir kitchen room. Since the church pews are usually on one Wooden pedestal, it comes due to the high radiation temperature temperature below the wooden planks to form condensation, the leads to putrefaction processes. The wooden platforms wear out in half the usual time through the putrefaction process. in addition comes that due to the high surface temperature of the heating the dust smoldering is very high and therefore with the churches heated by high temperature radiators due to the Dust smoldering in interaction with the condensation water on the cold walls very quickly and very quickly soiled.

The invention is based on the object of a heater to create spotlights of the type described in the introduction the acquisition costs and the operating costs are low, through which the above-described accident hazards are eliminated that and also the requirements of thinking protection in connection with the heating of a church enough.

This object is achieved according to the invention with a radiant heater which has the features specified in the claim. The radiator surface is provided on the inner surface of the enclosed space with an electrical resistance heating element in the form of a surface heating element, since this results in the lowest construction and operating costs. By limiting the maximum surface temperature of the radiator surface to 60 ° C, there is a reduction in the connecting line for the electrical resistance heating element to a value of, for example, 2.5 W / cm, that is to say a reduction in the connected value by almost half of the conventional electric radiator heaters. By limiting the surface temperature to max. 60 ° C excludes any dust smoldering. Due to the low temperatures, there is no condensation under the wooden platform. By interposing the radiator surface between the heating element and the room, only a mild radiant heat in the form of long-wave heat rays is emitted to the room, which is also perceived as pleasant and comfortable in terms of thermal physiology. Another significant advantage results from the fact that the radiator surface is bulged against the floor. The term "bulge" in the sense of the present invention encompasses both radiator surfaces with a semicircular cross section or generally continuously curved contour, and also with a polygonal contour in cross section. In the simplest embodiment, a polygonal cross-sectional contour can be formed by two flat radiator surfaces, which are arranged at an angle of, for example, 901 to one another, the apex area being directed towards the space floor and the side of the triangle formed in this way lying opposite the apex area Bench surface or the intermediate thermal insulation layer is formed. This arrangement has the advantage that, despite egg ner low height, the radiator surfaces are each the Fußbe rich of the neighboring, ie the before and / or behind standing bank facing, so that there is an overall overlap of the radiation cone for the loading under the successive banks arranged radiant heater is given, ie the radiated energy has no Schattenzo NEN, so that for the radiant heater according to the invention, with the appropriate design, the effect of underfloor heating with heat radiation q _s of about 70 to 75 W / m ² k arises. The direction of radiation can be optimally adjusted via the angular position of the two emitter surfaces. Compared to a flat radiator located under the seat, the heating surface is increased by approx. 25%. In the formation of the radiator surfaces in the form of a half-shell or egg nes half-cylinder, there is even a heating surface increase compared to the flat radiator of about 60%. The beam surfaces can be manufactured in a simple manner from a correspondingly bent or folded steel sheet.

The proposed surface heating conductor is known per se and be essentially consists of two temperature-resistant plastic foils lien that tightly enclose a carbon layer that ih on the one hand connected to an electrical supply and discharge line is so that when the electrical current passes through the Define carbon layer exactly according to the specification surface temperature is reached. The surface heating conductor is expediently on the inner surface of the beam lerfläche glued so that the heat generated by heat line reaches the surface of the radiator surface and emitted to the room as long-wave heat radiation can be.

The surface of the box-shaped heater body can be smooth be trained so that dust deposits are avoided the. Such box-shaped radiator bodies can be ferti Ge components are prefabricated in the factory and each Provide appropriate connector elements on the front be so that an electrically safe and easy assembly several such radiator bodies under one continuous Pew is possible.

An advantage of heating with radiant heaters according to the invention consists in the fact that even a small church interior still has zones can be divided wisely, so that, for example, for Got  tes services on weekdays with few visitors, through correspond appropriate circuit breakdowns only a predetermined small number of benches is heated while for worship on Sundays and public holidays with full church attendance Heating devices can be switched on at all banks. Operation is possible in such a way that the individual NEN body is equipped with thermostats that when a temperature of max. Open 60 ° C and at Close the temperature again to around 45 ° C, see above that even with a design limit maximum surface temperature of 60 ° C an additional Ab fuse to protect against overheating on every heater give is.

However, the radiant heater according to the invention is not only for little used church rooms, but also allows use in church rooms with a full Warm air heating system designed for space heating are. In such full-space heaters is during the heating period a relatively high basic temperature get right, which is then increased for worship, whereby to avoid damage to the interior of the church heating to the desired room temperature for the god service of 18 ° C, for example got to. If you equip one with full room heating also equipped the church with radiant heaters according to the ing invention, there is a possibility for Tem perieren this church, which is characterized in that a basic temperature for the church interior via the warm air heating tion of only about 5 to 10 ° C, preferably 8 ° C, and that for short-term heating before and during of the service the temperature by initiating the Heat radiation over a max. jet heated to 60 ° C surface in the area under at least part of the banks ke is done. The full room heating is then practically off finally from a conservation point of view drove with the preferred basic temperature of 8 ° C, so that  keeping the air humidity constant for the church interior results. Only the visitor blocks can be invented via the radiant heater according to the invention. For existing full this results in a considerable reduction in space heating of operating costs. In the case of new systems, this combination Procedure for the full room heating system be reduced overall. With a continuous operation full room heating even during periods of non-use, with which a basic temperature of about 8 ° C is maintained the church walls are kept dry and by the relatively high surface temperature of the walls a sweat formation prevented. Because the full room heating for the user times need not be ramped up, that is in the Desorption process of moisture release from the wall surfaces very much smaller, so that overall by the procedural combination of full space heating with the Heater optimization of the indoor climate is achieved, ultimately to avoid construction damage and leg leads to malpractice, in the case of incorrectly conceived church buildings tongues are inevitable.

Another advantage of this procedural combination be it says that especially with large churches that are only open to a few people are fully occupied on high holidays, beyond the restriction the heating of the foot area under the benches in predetermined NEN blocks the total heat input into the church interior can be reduced, so that there is also another Stabilization of the indoor climate results.

The invention is based on schematic drawings of Aus management examples explained in more detail. Show it:

Fig. 1 shows a vertical section element was a space heater with a Flächenheizleiter as an electrical Wider,

Fig. 2 shows another embodiment of the radiant heater with a quartz heater rod as a heating element,

Figure 3 shows the arrangement of the heater ken. Under Kirchenbän,

Fig. 4 shows a church room in plan with block heaters that can be switched on and off.

The heater shown in Fig. 1 in a vertical section consists essentially of a box-shaped radiator body 1 made of sheet steel, which is attached under the seat 2 of a church pew. The radiator surface 3 is "bulged" downwards, ie towards the bottom, the exemplary embodiment shown in FIG. 1 having two flat, smooth partial surfaces 3.1 and 3.2 which are arranged at an angle of, for example, 90 °. The surface of the radiation body facing the underside of the seat surface 2 is provided with a heat insulation layer 4 . The radiator body 1 is screwed to the seat using screws 5 . On the inner surface of the radiator surfaces 3.1 and 3.2 , an electrical resistance heater in the form of a so-called surface heating conductor 6 is fastened, for example, by gluing. The surface heating conductor 6 are dimensioned so that the surface temperature on the outside of the radiator surfaces 3.1 and 3.2 does not exceed 60 ° C.

The further embodiment for a radiant heater, which is also shown in a vertical section in FIG. 2, is in turn formed by a box-shaped heater body 1 made of sheet steel, which differs from the heater body of the embodiment according to FIG. Fig. 1 differs in that the cross-sectional contour of the radiator surface 3 is curved, for example, is curved semi-circular. Also in the execution form acc. Fig. 2 can provide the inner surface of the radiator surface 3 with a surface heating conductor, as shown in Fig. 1 is. The flat side of the radiator body 1 facing the lower surface of the seat 2 is again provided with a heat insulation layer 4 .

In the embodiment shown in Fig. 2, a quartz tube heater 7 is shown as Heizele element instead of egg nes heating element, but as a heating element is not the subject of the invention.

In Fig. 3, the arrangement of radiator bodies of the embodiment is shown schematically. Fig. 1 represents the church pews Darge. The fact that the radiator surface 3 of the radiant heater 1 is "bulged" against the bottom 8 , as shown by Darge, results in heat radiation in each case in the foot area of the front and the back bench. The outgoing radiation cones are overlapping, so that there is a "shadow-free" heat radiation in the foot area of each bank row.

The church shown in Fig. 4 in a plan is now provided continuously for all benches in each bank row with two radiation bodies 1 . The radiation body 1 of each chenbank bank are now block by block in individual circuit blocks a, b, c, d, e and f connected to the power supply, so that the heating of the church can be specifically adapted to the number of worshipers in that accordingly only single blocks can be switched on.
