Definitions

  • This invention relates to the method of controlling the flow of heating medium through a multiple row radiator, in particular through the heating plate unit with an inlet port and an inflow fitting of the heating medium, with the first passing-through heating plate facing the heated room / space and with at least one heating plate situated behind said first plate intended for reducing flow of the heating medium for cutting or controlling the heating output, as well as of the multiple row radiator to provide a controlled flow of the heating medium and especially according to the patent claims 1 and 2.
  • radiators especially the heating plate units are manufactured as single or multiple row units, inside of which a space for the flow of heating medium, which is usually water, is provided.
  • the heating medium is supplied into the individual heating plates from the inlet port through the supply outlets and flows always symmetrically into each of the heating plates, i.e. the same amount into all heating plates, or asymmetrically, usually preferably into the first of the heating plates facing the heated room, using a system for flow distribution such as different screens, but there is always no possibility to control the flow ratio distributed among individual heating plates, or to close the relevant inlet, etc.
  • heating plates or those of other similar radiators are always hydraulically interconnected, so that it is impossible to control the flow of heating medium through a single heating plate without having to influence the flow of the heating medium through the second or subsequent heating plate of known mutually hydraulically interconnected multiple row heating radiators.
  • One example of approach that consists in preferring higher heating output of the front heating plate facing a heated room at a multiple row heating radiator is known from the published patent application (CZ PV 1998-2158), according to which the relevant double row or multiple row heating radiator is preferably provided with a single inlet port, which is connected only with the frontal heating plate facing the heated room.
  • the heating medium which flows through this inlet port, is distributed along the upper edge of the front heating plate and through suitably dimensioned feeding channels situated perpendicularly thereto, and which are preferably spaced equally in the frontal region facing the heated room. Regardless of whether the radiator is operated at full or partial load, the heating medium is in that way primarily supplied to the front heating plate and subsequently to the remaining heating plates of the multiple row heating radiator. Consequently, the front radiator plate will be warmer thus presenting more pleasant touch feeling than existing systems. Preferably, this advantageous effect is even intensified by the fact that the front of the heating plate has a higher radiation ratio.
  • At least one connecting tube or possibly a supply outlet are arranged in the system, and said item is preferably situated at the lower front corner area of the radiator heating plate, from which then the cooled- down heating medium flows into the bottom of the second heating plate situated behind it or possibly into the subsequent plate of the multiple row heating radiator.
  • the heating medium is supplied at first upwards to the upper longitudinal edge of the second or possibly the subsequent heating plate, wherein the liquid is again directed through the upper distribution channel provided and then it is supplied by means of perpendicularly attached flow channels to the second lower corner area with a connected outlet port.
  • the heating medium transfers the greater part of its heat to said frontal heating plate, while entering, already partially cooled, the second or subsequent heating plates, providing in such a way a reduced heating output.
  • the substance of the present invention is to improve the method of the flow control of the heating medium through the multiple row radiator, especially through the heating plate radiator that is equipped with an inlet and outlet ports of the heating medium with the first passing-through heating plate facing a heated room / space and with at least one subsequent heating plate situated in a row behind it with intended medium flow reduction for cutting or controlling the heating power, whereby the specified task is achieved by the invention, characterized in that the heating medium supplied through a common inlet port is distributed without restriction in individual heating plates, and then the liquid returns through individual drainage connectors to be selectively merged in a single outlet stream emptying into the outlet port.
  • the method of the flow control of the heating medium according to the present invention provides the advantage that the ratio of individual outlet streams of the heating medium from individual heating plates can be modified by selective merging in the range from 0 to 100% or vice versa.
  • the outflows of returning heating medium from all heating plates can be completely shut off through said selective merging.
  • the selective merging of the outflow of the returning heating medium from the individual heating plates can be set with predetermined ratio, or that the selective merging of the outflows of returning heating medium from the individual heating plates can be set individually or controlled with variable ratio.
  • the method of controlling the flow can be applied without special measures to every known multiple row radiator that consists of at least two rows of heating sections arranged one behind the other, in particular of the heating plates equipped with upper distribution channels and lower collecting channels interconnected by a system of vertical channels, and with distributing channels at every corner that are interconnected with supply fittings, which are blind, with the exception of one inflow fitting at the inlet port, whereas the supply fitting for the common outlet port is equipped with central separation screen for separating and attaching the individual outflows of the returning heating medium from individual heating plates into mutually separated channels of an additional body of the selective outflow mergers connected to a common outlet port.
  • the selective merger operation is advantageously based on the principle of flow throttling, and it is sufficient that throttling or closing devices for manual or motor controlled hydraulic resistance modification are arranged across of at least one of the mutually separated channels of the selective merger body.
