The inventor named: Lars-Olof Andersson in Saltsjöbaden

Sweden

The invention relates to a room heater with a arranged in a substantially vertical plane, A pipe or primary system through which a heat-emitting medium flows, with secondary, with the primary system

i elements in contact and with one the primary system and the secondary elements on the side of the room the tertiary element covering the heater, i.e. a front panel.

BATH 109884/1232

A variety of room heaters of this type are known. They are mostly used as convectors, in which a hot liquid or gas, mostly Water, passed through the primary system, to -this to heat and thus heat to the secondary Elements released, with the heated primary System and, to a greater extent, the secondary elements to those flowing vertically through the heater Air give off heat energy, while the front panel has only an aesthetic function and not essential to it Warming the room contributes.

Such convectors have a pleasant heating effect, you can attack them and they can be covered without the risk of a fire breaking out; however, they have one serious drawback: if they are placed near a large window and if the outside temperature is low, 'can they do not compensate for the heat radiation that a person in the room gives off through the window, which is what you gives a feeling of pull as the faceplate is cold

i and cannot emit any compensating thermal radiation.

Such convectors are also often relatively inadequate «

The main object of the invention is to provide a room heating device which does not have the above-mentioned disadvantages, but which ensures good and efficient heating of a room.

Another object of the invention is to provide a room heater which, despite its simplicity and a given size of the front panel, allows great variation in the number and arrangement of the secondary elements, while also making the capacity of the room heater variable.

Another object of the invention is to provide a room heater in which heating is easy and quick regulated. without changing the liquid or gas flow in the primary system.

Ultimately, it is an object of the invention to provide a room heating appliance to create, with which preheated air blown through the Zimmerhedz device can be heated up «

According to the invention, the main objective is achieved in that the primary system, the secondary elements and the tertiary element are dimensioned and arranged such that the entire heating effect mainly through Convection, and a small but not insignificant one

109884/1232 ORIGINAL BATHROOM

the heating effect through. Thermal radiation is caused by the tertiary element indirectly heated to a moderate temperature. The heat transfer to the tertiary elements should be set large so that the proper amount of ■ heat such as the primary system and the secondary elements is transferred to the tertiary element mainly by convection. In one embodiment of the room heater according to the invention this is achieved in that the secondary elements consist of corrugated metal sheets which are in good heat-conducting contact with the primary system on one side, the distance between the primary system and the tertiary element being in the order of 2.5 cm and where the secondary elements on the other side have a spacing of less. than about 1 mm to the inside of the tertiary element, the heat transfer to the tertiary element being effected mainly by convection. With such an arrangement there is also the advantage that the corrugated sheets of the secondary elements protect the tertiary element from the inside against mechanical deformation from the outside, which makes it possible to make the tertiary element thin and light, so that more expensive material, such as Aluminum, can be used.

109884/1232

According to a further characteristic of the room heater according to the invention, there is each secondary element from a corrugated sheet and from a substantially flat guide plate, which is connected to the primary system on the tertiary element opposite side is in engagement and with the corrugated iron by rivets or the like is clamped to firmly connect the secondary elements to the primary system, so that a good heat-conducting contact is established and to form walls in the vertical air shafts. These guide plates can have a guide flange bent out of the plane of the plate at their lower edge, around the to direct air flowing upwards into the air shafts.

Instead of such guide plates, corrugated plates can be used inside, so that the corrugated sheets in pairs are arranged on each side of the primary system and are connected to one another, e.g. by rivets.

In a room heater according to the invention

it is particularly advantageous if the secondary elements

i are arranged vertically and horizontally at a distance from one another so that relatively cold air can flow between the secondary elements, which when mixed with heated air creates air vortices and thus better convection heating and a more uniform surface temperature

109884/1232

of the tertiary element causes.

It is also possible to design the primary system in more than one level and the secondary elements to be arranged as required on each level.

It is therefore for a given size of the

tertiary element possible to vary the capacity of the room heater in a wide range. This may Be of great value when multiple room heaters are to be installed in a building, with all of the room heaters have the same appearance for aesthetic reasons but different capacities for technical reasons should. These requirements often occur in modern buildings with a small heat accumulating mass.

In order to pass on the air that is sweeping upwards

™ is the primary system, preferably with the tertiary one Element provided perpendicularly extending vertical edges, which also support the tertiary element and keep it at the correct distance from the primary system.

According to a further feature of the invention, the air flow in the vertical air ducts is through over or air flow control devices located under the air ducts regulated; this way you can do the heating

10988A / 1232

without having to readjust the valves connected to the primary system. These airflow regulating devices can be operated manually or automatically, depending on the room temperature. In such Valves it is even possible to use separate valves to regulate the heat-emitting liquid or gas in to do without any room heater.

In some cases it may be advisable to introduce additional air into the room by passing through an air duct opening air blows under or behind the room heater. The air can be preheated in the air duct or on a slightly below the desired room air temperature are cooled; the room heater can be used as a The heating device works to reach the last desired temperature. To enable precise regulation, can be automatically operated air bypass valves depending regulate the airflow from the actual room temperature. In connection with this, the secondary elements in a zone above each opening of an air duct may be less spaced from one another than in the

other vertical zones.

The distance between the room heater and the wall or the rear panel can also be varied as required. The room heater can, for example, be equipped with variable or exchangeable

• 1Q988W 1 232

be provided ble support members, whereby the room heater can be arranged at a suitable distance from the wall of the room, so that the heat capacity is variable is.

Finally the room heater can be incorporated in a wall of the room, wherein the primary system and the secondary elements, the f tertiary element forming wall of the room are arranged one behind another, and that in the vicinity of the floor or the ceiling in the wall of an air inlet and an air outlet are provided.

These and other features of the invention will become apparent in the following description with reference to the drawings explained in more detail.

Fig. 1 shows the room heater according to the invention in perspective view from the room, with the essential facilities behind the front panel or dera tertiary element, namely the primary system and the secondary elements are shown in dashed lines;

FIG. 2 shows a part of the room heater of FIG. 1 in perspective from the rear; it is illustrated like the secondary element by a guide plate with the

1Q988A / 1232

Fig. 3 shows a view similar to Fig. 2; however, the secondary elements are in pairs at one each Side of the primary system arranged;

Fig. 4 shows how the primary system works through

vertical edges are properly spaced from the faceplate or tertiary element;

Fig. 5 is a perspective view of a room heater according to the invention, with behind the Air ducts opening into the room heater and air flow control devices arranged on the room heater which regulate the airflow through the heater, illustrated will.

Essentially, the room heater in Fig. 1 consists of a primary system 1, which is through a vertical aligned pipe system is formed through which a heat-emitting liquid or gas flows, from secondary Elements 2, which are in good heat-conducting contact with the primary system, these secondary elements Form air shafts, and from a tertiary element (Fig. 5) that from a parallel to the primary system Front panel consists and the primary system

109884/1232

and the secondary elements 2 on the room side, des Room heater covered.

The primary system 1 has an inlet valve k , which is not absolutely necessary in some cases, a main pipe 5, an air trap 6, XJ-shaped parts 7 and a return 8.

As can be seen from FIG. 2 or FIG. 3, the secondary elements 2 are attached to the U-shaped parts 7. Each of the secondary elements 2 according to FIG. 2 consists of a corrugated sheet 9 and a guide plate 10, which is connected to the corrugated sheet 9 in this way by rivets 11 stands that the U-shaped part 7 of the primary system "1 between the sheet 9 and the plate 10 in good conductive connection with the sheet metal or the plate is held. The sheet 9 and the plate 10 together form vertical air shafts or passages for the air flowing upwards through the room heater. At the bottom Edge of the guide plate 10 is a guide flange 12 is arranged which is bent outward so that the air iin. the vertical air passages must be deleted. An alternative embodiment of the secondary elements 2 is shown in FIG. 3 shown where on each side of the U-shaped parts 7 of the primary system corrugated sheets 9 are arranged to collectively to form vertical air shafts.

The Zimmerlieizgerät works essentially in the following way: A heat-emitting liquid or Gas, i.e. water or water vapor, is passed through the primary System 1 guided and mainly through conduction to the secondary elements 2 and through Convection dissipates heat to the Lvift flowing upwards. The majority of the heating effect of the room heater is achieved by this heated air flow during a a small but not insignificant part of the heating effect caused by radiation from the tertiary element 3 that by the heated air and to some extent by radiation from the primary system 1 and the secondary elements 2 is indirectly heated to a moderate temperature.

To achieve this it is very important that the correct amount of heat is transferred to the tertiary element 3; According to the invention this is achieved in that the distance between the primary system 1 and the tertiary element is 2.5 cm and the secondary elements 2 are arranged at a distance of less than 1 mm from the inside of the tertiary element 3 & ^{n of} the room system. The primary system 1 and the secondary elements 2 must therefore be kept at a precise distance from the tertiary element 3.

109884/1 232

Fig. 4 shows how a secondary element 2 (9, 10) and a U-shaped part 7 of the primary system 1 are held at a fixed distance from the tertiary element 3 by a vertical edge 13; the edge consists of two side by side plates 14, 15 each clamped to one side of an inner flange 16 of the tertiary element 3 and extending at right angles to the rear relative to the tertiary element 3 and the primary system 1. In the edge 13 cutouts are provided through which the U-shaped parts 7 of the primary system 1 extend and against the inner edges of which the U-shaped parts are held by flanges 18, 19 and locking eyes 20, 21 projecting from the plates 1h and 15 will. With this arrangement, a satisfactory heat conduction and fixed distances between the various elements are achieved and that

^ Room heater can be assembled easily and quickly will. The fact that the secondary elements 2 are at a distance of less than about 1 mm from the tertiary Element 3 arranged are complicated that a narrow air shaft could be present between them, or that

the corrugated sheet 9 has a narrow protruding part which is held against the tertiary element 3. It is essential that the conduction of heat should be prevented.

0 9884/1232

The secondary elements 2 can be arranged vertically and horizontally at a distance from one another, such as from Fig. 1 emerges. Relatively cold air can then flow between the secondary elements and through mixing With heated air, an air vortex is created, which creates an even better warming of the air, as well as a more even one Surface temperature of the tertiary element Here, the guide flange 12 (see. Fig. 2) is large Benefit, since even if the air has swept past the outside of the lower secondary elements 2, forcing the air into the air passages. In order to equip the room heater with a larger capacity, this can primary system can be arranged in two or more parallel planes, with the secondary elements in all three dimensions can be spaced apart.

Of course, the heat output capacity of the room heater can be regulated by turning the inlet valve 4 of the primary system 1 regulated; with a constant flow of the heat-emitting liquid or gas through the primary

System can control the heat output capacity by placing airflow regulators at the top or bottom Part of the room heater arranges through which the room heater leaving or coming in below Air flow is throttled. A deiepicl of an air flow

1 0988A / 1232

control device 22 on the upper part of the room heater is shown in FIG. Such an air flow control device 22 can be operated manually, as shown in Fig. 5. or automatically., depending on the inside or outside the room's given air temperature.

In addition, the heat output capacity of the room heater can be varied or increased by maintaining the air flow through the room heater through a fan or the like; the fan is arranged so that air is blown into an air duct opening under or behind the dome room heater. Such an arrangement is shown in FIG. Two air ducts 23 open into the TCand behind the room heater and make it possible that cooled or preheated air is blown through the vertical air shafts of the room heater; the air is heated in this way and is let out in a controlled manner by the air flow regulating devices 22. The * through the air duct blown air may be so pre-heated or chilled to a temperature slightly lying below the desired room temperature; in this case, the room heater works as a heating device in order to precisely reach the room temperature ultimately required. Automatically operated air bypass valves (not shown) can also be used for this fine regulation of the room temperature.

In. the room heater. 5, which has air inlets 23 under or behind the room heater, the secondary elements 2 can also be arranged in such a way that they are less distant from one another in a vertical zone Zh above each air inlet 23 than in the other vertical zones. This is particularly advantageous when the air in the air duct is much colder than the air in the room.

Another possibility to make the capacity of the room heater variable is that one provides the room heater with variable or interchangeable support parts on delivery through which the room heater can be mounted at a suitable distance from the wall of the room.

Finally, within the scope of the invention, the primary system and the secondary elements are behind one To arrange the wall of the room, this ¥ and the tertiary element and a certain heat radiation delivers, and with an air inlet and an air outlet in

i are arranged near the floor or ceiling so that the air in the room can circulate through the vertical air ducts of the room heater and is thus heated will.
