Description

Technical field

BACKGROUND OF THE INVENTION The invention relates to a method for controlling the flow of a heating medium through a multi-row radiator, in particular a radiator with an inlet and a heating medium outlet, with a flow-through first heating plate facing the heated room in space. reducing the flow rate of the heating medium to reduce or control its heat output, as well as a multi-row radiator for performing methods of controlling the flow rate of the heating medium, in particular according to claims 1 and 2.

BACKGROUND OF THE INVENTION

At present, the radiators, especially the radiators, are manufactured as single-plate or multi-row radiators, within which space is provided for the flow of heating medium, usually heating water. The heating medium is fed to the individual heating plates from the inlet connection via glands, always to all of their heating plates symmetrically, ie to all heating plates in the same amount or asymmetrically, usually preferably to the front heating plate facing the heated room, for example of various partitions, but always without the possibility of controlled regulation of the flow rate of heating medium into individual heating plates or their closing etc. Internal spaces of heating plates or other similar radiators are always hydraulically connected, so it is not possible to control the heating medium flow in one without altering the flow rate of the heating medium through the second or further heating plates of these known multi-row hydraulically connected radiators.

One example of a preference for the higher heat output of a front panel facing a heated room of a multi-row radiator is known from the published patent application (PV 1998-2158), according to which the double-row or multi-row radiator preferably has a single inlet connection which is only connected to front panel on the side of the room. The heating medium flowing through this inlet connection is distributed along the upper edge of the front heating plate and by means of perpendicularly positioned and suitably sized flow channels, preferably evenly distributed in the front facing the room. Irrespective of whether the radiator operates in the full load or partial load range, the heating medium is thus fed into the front heating plate preferably and then from there to the remaining heating plates of the multi-row radiator. Then the front heating plate will be warmer at the same heating output and thus more pleasant to feel than with existing systems. Preferably, this advantageous effect is further enhanced by the fact that the front heating plate has a higher radiation proportion.

In order to allow the heating medium to flow from the front heating plate to at least one other heating plate or the like located thereafter, at least one connecting pipe or pipe is arranged in their assembly. an outlet, which is preferably located in the lower corner region of the radiator front panel, which overflows the partially cooled heating medium into the lower part of the second radiator panel located behind it, eventually. to another heating plate of a multi-row radiator. In this second heating plate, the heating medium is first guided upwards in the direction of the upper longitudinal edge of the second event. another heating plate, where it is again divided by the upper distribution channel located here and by means of perpendicular flow channels connected to it, is fed to its second lower corner area with the connected outlet connection. It is believed that the heating medium releases most of its heat in said front heating plate, while partially cooled, it enters the second or further heating plates, providing a reduced heat output.

The obvious disadvantage of such an arrangement is that the regulation of the reduced heat output of the second or, in the case of another heating plate of a multi-row radiator, cannot be controlled in any way. Another disadvantage of this

The solution consists in the fact that, compared to the standard solution of multi-row radiators, when the hot heating medium flows evenly into all the radiators and cools there, the heat output of the entire radiator is generally lower, since the hot heating medium flows first The heating medium cooled to the front heating plate and to the second or even further rear heating plate flows, thereby reducing the heat output of the second and possibly another heating plate.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for controlling the flow of a heating medium through a multi-row radiator, in particular a radiator with an inlet and a heating medium outlet, with a flow-through first heating plate facing the heated room / space. by reducing the flow rate of the heating medium to reduce or control its heating output, the object of the invention is to disperse the heating medium from the common inlet connection without restriction to the individual heating plates, and thereafter after parallel individual outflows the returning heating medium selectively combines in a single outlet before the common outlet connection.

The method of controlled flow of the heating medium according to the invention brings the advantage that the individual outflow rates of the returning heating medium from the individual heating plates can be varied in the range of 0 to 100% or vice versa.

Furthermore, it appears advantageous that, by selective combining, the effluents of the returning heating medium from all heating plates are purposefully closed.

Taking into account the prevailing conditions in the heated rooms as well as the amount of thermal energy in the heating system, it is particularly advantageous that the selective combining of the return heating medium effluent from the individual heating plates is set with a predetermined relative ratio, or the heating medium from the individual heating plates is set individually or controlled with variable ratio.

It is advantageous according to the invention that the controlled flow method can be applied without any special precautions to any known multi-row radiator comprising at least two rows of heating elements arranged one after the other, in particular heating plates equipped with upper distribution ducts and lower collecting ducts interconnected by a system of vertical ducts; in each corner of the distribution channels with interconnected outlets which, with the exception of the inlet outlet at the inlet connection, have the other outlets blind, but the outlet for the common outlet connection is equipped with a central dividing wall to separate and discharge individual outflows of returning heating medium mutually separated channels of the selective drain combiner additional body connected to a common output connection.

The function of the selective combiner is preferably based on the principle of flow throttling, provided that it is sufficient that throttling or closable flow resistance means, manually or motorized, are provided across at least one of the mutually separated channels of the selective combiner body.

The construction of a multi-row radiator according to the invention does not in any way limit the conventional equipment of such a radiator such as a central control valve or the like, in series with an inlet connection and inlet for the distribution of the heating medium into all the radiators.

DETAILED DESCRIPTION OF THE INVENTION

Method for controlling the flow of heating medium through a multi-row radiator 1, in particular a multi-row radiator panel with an inlet connection 2 and a heating medium outlet connection 3, with a flow-through first heating plate 4 facing the heated room (space). A plate 5 with the intended reduction of the flow rate of the heating medium to reduce its heating output is illustrated by using a plurality of figures of variants of a multi-row radiator 1, comprising, for example, at least two rows of known heating plates 4, 5 arranged in series. and lower collecting channels 7 interconnected by a set of vertical channels (not shown).

1, 5, 6 and 8, the radiator plates 4, 5 of the radiator 1 are fixed to each other in the corners of their upper distribution ducts 6 and the lower collecting ducts 7 by means of spacers 8 which are fixed to one another. however, unlike conventional and known outlets, they are blind, non-flow as shown in the figures hatched, except for the inlet outlet 9 at the heating medium inlet connection 2, the necessary outlet outlet 10 for the common cooling medium outlet outlet 3 being equipped with a separation separator a crossbar 11 (indicated by hatched lines) for separating the individual outflows of the returning heating medium from the individual heating plates 4, 5 or groups thereof to the mutually separated channels 12, 13 of the selective combiner 14 of said individual outflows. The selective combiner body 14 is then connected directly or via a screw connection 15 to a common output connection 3 by its output.

The spacers 8 are blinded at the factory or are additionally provided with various flexible partitions 16 and the like, and at least one of them is provided with a vent valve (not shown).

It follows from the arrangement of the radiator 1 shown, as also shown in FIG. 7, that the heating medium inlet and outlet chain can be arranged upside down, namely that the heating medium is selectively distributed by means of a selective splitter 14 with a hub function already in the inlet duct 9 equipped with a separating partition 11 for this purpose, the outlet outlet 10 connecting the individual individual outflows from the heating plates 4, 5 is freely flowing together with the outlet via the shut-off fitting 15 to the outlet connection 3. Combiners 14, now with selective splitter function, the conventional control valve 20 (FIG. 7a) may be upstream, or the combiner 14 and the control valve 20 may be connected in one device 25.

In cases of up to three-row and multi-row arrangement of heating plates 4, 5 in series, the groups of each additional heating plate 5 are mechanically and hydraulically interconnected at the corners of their upper and lower distribution channels 6, 7, for example by flow spacers 16. of the above outline of the basic arrangement of the multi-row radiator 1, are blind and the like.

The selective combiner body 14 is, as indicated above, designed as a two-channel, and according to a large number of variant embodiments thereof, can be provided in one of its channels 12 with a simple throttle orifice 17 with different pre-selected throttle openings 18 or across the two separate channels 12, 13 flow control means 19, for example rotatable flaps, sliding and possibly rotary valves, throttle screws, valve plugs, etc., pre-set at the factory or manually, or motorized, after installation of a multi-row radiator 1 in a heating system , in order to achieve the desired change in the hydraulic resistance of the individual channels 12, 13 of the selective combiner 14, or the hydraulic resistance of the individual heating plates 4, 5 or their heating medium groups

-4GB 307673 B6 entering the multi-row radiator assembly 1 through the inlet 9 at the inlet port 2, usually equipped with a shut-off or control valve 20.

From the described example of the arrangement of the multi-row radiator 1, together with the frame accessories, it is evident that the heating medium from the common inlet connection 2 diffuses substantially without limitation into the individual heating plates 4, 5 of the multi-row radiator 1, , after parallel individual outflows, the returning heating medium selectively combines in a single outlet in front of the common outlet connection 3, achieving the effect that, in particular, behind the flow first heating plate 4 facing the heated room or space, of the heating plate 5, it is intended to reduce the flow of heating medium passing through it and thus to reduce its heating output, or vice versa, etc.

The present method of controlling the flow of heating medium through a multi-row radiator 1, in particular a panel radiator, due to the use of an optional and sophisticated design of a selective combiner 14, also has the effect that the individual return flow rate by combining varies from 0 to 100% or vice versa.

Also, the selective combining, again according to the selected design of the selective combiner 14, can only be completely interrupted by completely shutting off the return of the heating medium from all the heating plates 4, 5, thereby satisfying the current requirement of having radiators 1 equipped with a lower closing screw 15. .

Said selective combining of the return heating medium outflows from the individual heating plates 4, 5 is adjusted with a predetermined relative ratio already at the factory, or the selective combining of the return heating medium outflows from the individual heating plates 4, 5 is adjusted individually or controlled with a variable ratio as required by the user or automatically depending on ambient thermal and other conditions, for example by means of an actuator 21 with a corresponding sensor 22 (Fig. 6) and the like.

Selective pooling of the return heating medium outlets, or the design of the selective combiner / splitter 14, does not prevent the radiator 1 provided by it from being adapted to the classical upper connection to the heating system or to be provided with a so-called bottom connection 23 (FIG. 8). bottom central connection using known valve gauges 24 and the like.

The construction of an exemplary arrangement of a completely simple two-channel hub body 14 with connection to an outlet gland 10 with a separating separation bar 11 is shown in FIGS. 9, 10. At least one of the parallel channels 12, 13 has a throttling orifice 17 with a preselected throttle bore diameter. 18.
