Description

Fig. 1 shows a classic, used by all installers Central heating system used with a boiler 1, a circulation pump 2 and an expansion tank 3, which is usually placed in the attic of the building. Each radiator 4, im The present case is nine radiators, is with the circulation pump 2 and with the Inlet opening of the boiler through a number of pipes of different diameters from 0.5 "to 2", as indicated on the drawing on the individual pipe sections.

The difficulties of such a system are easy to see. These exist once in the Diversity of the pipelines to be laid, also in the intended welds around pipes to connect different diameters with each other and finally in a considerable amount of work, in order to create sufficiently large openings in walls and ceilings for the relatively thick pipelines etc., quite apart from the fact that the suitable pipe diameters are calculated and determined beforehand have to.

In Fig. 2 is, for example, a heating system according to the invention with likewise new radiators reproduced that of those according to F i g. 1 corresponds. Elements which correspond to those of FIG. 1, have been given the same reference numerals. In the present case, the Boiler 1 at its outlet opening or its inlet opening each have a flow collector 5 or a return collector 6. On the flow collector 5, the circulation pump 2 is arranged, while the expansion tank 3 is located in a special design as a pressure vessel on the return collector.

Pipes 7 are attached to the flow collector 5 behind the circulation pump 2 by means of suitable connecting members, which lead to the radiators 4, while on the return collector 6 between the boiler 1 and the expansion tank 3 from the radiators 4 pipes 8 coming from the radiators 4 are fastened by means of such connecting members. At the end of the return collector 6 there is also a safety valve 9.

The pipes 7 and 8, which are preferably made of annealed copper, are of the same design and have a small diameter, in the exemplary embodiment about 3/8 ". Each radiator has thus a double pipeline that leads to and from the boiler via one of the collectors 5 and 6, respectively (Supply and return lines).

The assembly of such a system is very simple: after a careful study of the heating power to be installed in the case in question

ίο the installer first provides the boiler the two collectors, the circulation pump, the control and safety devices, the expansion tank (designed as a pressure vessel) and the other necessary facilities, e.g. B. the burner and the oil tank if it is an oil heater. Then the radiators are set up, the factory-like ones already provided with shut-off cocks, condensate pots and connecting elements as well as brackets are. Finally, with special connecting means, metal pipelines in rolls become larger Length attached to attach them to the connecting members of the radiators.

After the boiler 1 has been installed in the basement, the owner of the system can either himself or anyone low paid unskilled workers install the radiators on the walls and each radiator connect to the two collectors using the piping supplied, with the uniform small cross-section of the supply and return pipes eliminates the previous risk that the pipes are wrong be relocated. Furthermore, the small cross-section of the tubes has the advantage that only small holes in the walls are required and therefore only very little damage to the floor, ceilings and Walls.

This connection of the pipelines does not require any welding or thread cutting. Preferably a supply and a return pipe are placed between the radiator and the boiler used. Where the pipes have to be cut, the individual parts can be tapered using double Transition pipes are connected to each other. The connection of the pipes to the radiators and collectors is also done by means of

double conical transition tubes.

1 2 system is the Tichelmann system (Recknagel patent claims: Sprenger, pocket book for heating, ventilation and air conditioning, Munich 1960, page 492 ff). Here 1. Central heating system for any combustion is provided that the radiator that the substances with forced circulation of the heating medium, when the 5 boiler is closest, the longest return from one boiler and one line to it is assigned, etc. In this way, the connected flow and return collectors, at the sum of the pipe lengths for each radiator in the which kept the supply and return lines leading to and from the radiators constant, and Flow and return lines are connected, the important factor for the balance »pipe thereby marked that on the previous length «eliminated. However, this construction requires running collector (5) a circulation pump (2) and on a considerable pipe expense and is therefore not Return collector (6) as a pressure vessel - recommended, desired or economically developed from anywhere Compensation tank (3) is connected, borrowed. and that all supply and return lines, on the other hand, the classic design provides (7, 8), which connect the radiators (4) with the supply and 15 the pressure gradient across the various radiator return collectors (5, 6), a single through different pipe diameters in the uniform small, constant cross-section fore and Keep return lines constant,

Central heating system according to claim 1, deficiency of the known heating systems by a characterized in that the boiler (1), 20 avoid the central heating system that is inside the flow and return collectors (5, 6) can be installed with their very short time, with it Connecting links for the flow and return is unimportant, whether an unskilled worker or the lines (7, 8) and fittings on the one hand and the owner of the system carries out the installation himself, Radiators (4) with their valves, condensate - since they run no risk of making a mistake, pots and connecting links on the other hand, factory 25 The new heating system should be designed in such a way that moderately designed as pre-assembled units that a pre-assembly and possibly also Versind, searches are already feasible in the workshop. ^; The invention is seen in the fact that on before collector a circulation pump and on the return 30 collector is connected as a pressure vessel designed compensation tank, and that all pre and Return lines that connect the radiators to the supply The invention relates to a central heating system, and connecting return collectors, have a uniform for any fuel with forced circulation of the small, constant cross section.
Heating medium, consisting of a boiler and 35. An advantageous development of the erfindungsje one connected flow and return central heating system is that collectors, to which the to and from the radiators of the boiler, the flow and return collectors with leading flow and Return lines connected to their connecting elements for the flow and return, lines and fittings on the one hand and the heating Such a central heating system is generally known from the factory with its valves, condensate pots and anchors, for example from the German disengagement members, on the other hand, as prescribed 1 090 416. In systems of this type, in which controlled units are formed,
The boiler consists of a number of individual tubes. The technical progress of the invention consists forms, it can easily happen that with strong in it that a considerable gain of time as well as a the pressure drop caused by the pipes in the 45 better quality and economy can be achieved, Steam formation takes place in pipe strings. To avoid this thanks to the fact that with the help of suitable work is the complete pre-assembly in the machine tools in the older version mentioned a short-burst line to be operated temporarily between the factory and the installation of the system see the flow and return collectors provided. even from the owner of the plant or one The installation of such an arrangement, designed in the manner of the classic 5 ° less paid, unskilled auxiliary staff, can be realized because the pipelines for the connection require a considerable amount of work, which of the system elements on pipes of a single one, among other things, wrestles with the installation of pipes Are standardized in diameter. The fact that large diameters are due. With this one compensating tank no longer working under the roof, there are various disadvantages for the user. In this way, the apartment is excluded from the risk of freezing and for a certain period of time it becomes a real construction site, where there are considerable savings in installation costs. Craftsmen punch large holes in the walls. Furthermore, it avoids the need to carry out considerable cross-section and oxy-fuel welds, reducing the connection pipelines, which can dirty the apartment, painting and paneling.
