Definitions

  • the invention relates to a two-row or multi-row radiator, in particular flat radiators, according to the preamble of claim 1, a single-row radiator with a plate trained radiators and an electric radiator.
  • Flat radiators are usually made from profiled or embossed half-shells preferably made of sheet steel, which are welded together and thereby can form horizontal and vertical flow channels.
  • profiled sheets convection profiles or sheets
  • Rectangular profiles attached to the radiator surfaces. Include flat radiators - in terms of heating output - to the cheapest radiator types and stand out in addition to advantageous decorative and hygienic properties, above all through a comparative low mass, which has an advantageous effect on their control behavior, in particular with regard to energy-saving heating systems.
  • Heating systems and thus radiators are usually extremely low Outside temperatures (so-called design case) designed at which a pleasant room temperature to be provided.
  • design case serve as parameters for the design of the radiator the amount of water flowing through the radiator, the flow resistance and the ratio of the radiator sections with predominantly convective and radiant heat emission. If these parameters are therefore usually matched to extreme heating conditions, the so-called partial load range with comparatively lower required Heating output, which predominates over most of the heating period, is different Design and a different behavior of the radiator.
  • single-row flat radiators have a single heating plate with an essentially one-piece construction.
  • have two rows Flat radiators i.e. Radiator with a front facing the room to be heated Plate and a plate arranged behind it, usually a symmetrical one Structure, the front and rear heating plate always symmetrical, d. H. with the same amount of water, is flowed to. This also applies to the two front heating plates a three or more row flat radiator.
  • the mentioned one-piece or symmetrical structure disadvantageous.
  • Radiators only provide heating outputs of a few 100 watts, so that they only relatively little water flows through it. Because of the usually high proportion the convection at the total heat dissipation becomes the only or front, the room facing section of a single-row radiator with convection plates a comparatively have low temperature.
  • This disadvantageous effect is seen in multi-row radiators reinforced due to the symmetrical structure, because not only for heating the front section also serves sections arranged behind it. Thus, over the front heating plate only dissipated part of the total heat. At low heating output the front heating plate remains comparatively cold. Compared to body temperature cold radiator surfaces adversely affect the indoor climate because they are perceived as uncomfortable.
  • DE 196 143 30 C1 and DE-A-4041191 show a radiator with two heating plates, which are connected via a connecting line are connected to each other with a valve. Both heating plates are as convectors designed so that the disadvantages indicated above and below occur here too.
  • the invention has the task of the Einzzw. Multi-row radiators while maintaining the achievable heating output in view to further develop the special conditions in the partial load range in such a way that the Comfort can be increased that the surface facing the room or at least Larger sections of it should be as warm as possible in the partial load range, furthermore that the design of the radiator can be adapted to full and partial load operation can, so that the overall beneficial properties of flat radiators in all respects can be maintained or even increased.
  • Advantageous properties here include the high heating output in comparison understand the low heating and manufacturing costs as well as the good control behavior, So features that directly affect the comfort and indoor climate of the heated Impact space.
  • a two-row or multi-row radiator according to the invention preferably has one only flow connection that is only connected to the front or room-side heating plate is.
  • Warm water that flows in through this flow runs along the top longitudinal edge the foremost heating plate and by suitably trained vertically running for this Flow channels as uniformly as possible over the foremost, facing the room Section distributed.
  • warmer water is thus supplied to the front section than the rest Sections.
  • the front section becomes warmer with the same heating output and therefore feel more comfortable than with conventional systems.
  • This is preferred advantageous effect is further enhanced by the fact that the front section has a higher proportion of radiation than the remaining sections of the radiator.
  • At least one connecting tube is provided, which is preferably in a lower Corner area of the radiator is arranged.
  • Water flowing into the hotplate behind flows in is preferably first led upwards in the direction of the upper longitudinal edge, redistributed from a transverse channel located there and via perpendicular to it Flow channels fed to a return connection in the lower corner area.
  • the water can be guided in the third and all subsequent sections take place accordingly, which is the fluidic of Series connection of three or more radiators corresponds.
  • a three-row radiator is however also the parallel connection of the two rear heating plates and their series connection possible with the foremost heating plate, for which purpose the connecting tube is useful between the front and the second heating plate to the rearmost heating plate becomes.
  • the front radiator is first supplied with hot water is, so that this is in the partial load range compared to conventional radiators will have a higher surface temperature, making it a much more comfortable one Can convey indoor climate.
  • a radiator according to the invention has a more uniform temperature profile on the radiator surfaces.
  • the water temperature after flowing through the front radiator for example in the Full load operation has not yet reached the return temperature, as is the case with conventional ones Systems would be the case, but assume a value that is roughly in the middle between the flow and return temperatures are.
  • the temperature distribution over the Radiator surface more uniform, what the design of the radiator as well as its construction facilitated.
  • the more even temperature profile is particularly advantageous in the partial load range, which can be seen from the example if a radiator thermostat the flow rate of the water so that the water temperature after passing through the front radiator has almost dropped to room temperature, whereas this with the same heating output for a conventional, symmetrical flow Radiator would already be in the middle of the radiator, the surface of which is would mostly feel cold and uncomfortable.
  • a double-row radiator is expedient only on its rear Heating plate be provided with convection profiles, so that such an inventive Radiators on the room side have a relatively large proportion of the total heating power, the rear convection section is no longer heated in the partial load range.
  • the so-called design case the maximum heating power if the outside temperature is very low, this is especially the case with relatively mild outside temperatures, which predominate predominantly, a comparatively high proportion of radiation exhibit.
  • the rear heating plate is also heated, so that the amount of convection increases.
  • radiator exponent of such a radiator does not cover the entire Temperature range is constant, but in the partial load range due to the much larger Radiation share is smaller than with larger heating outputs, where the convection part is bigger.
  • a radiator according to the invention thus helps heating costs, especially in the part-load range, which makes up a large part of the heating operation to save.
  • the heating plate facing the room is warmer is what is actually desirable for every radiator, because not the back wall but above all, the room should be heated, which, however, with the symmetrical design conventional radiator is not feasible. So less heat goes through the behind radiators often thinner wall insulation is lost to the outside.

  • the radiator according to the invention is required just turn it over so that the room-side heating plate is a comparatively acceptable one Temperature. Should the thermal insulation or the district heating system become one can be improved at a later point in time, so you need at lower flow temperatures just turn the radiator according to the invention, so that then advantageous properties mentioned above come into full effect without a new one Radiator must be purchased.
  • both the flow and the return connection are on one side edge of the radiator.
  • the hot water is fed into the center of the front heating plate, where it then a left and right flow branches until it - in the case of a two or more rows Radiator - in the area of the center of the rearmost heating plate back into the water return is fed back.
  • the hot water at the top of the front radiator fed.
  • both the flow and the return at the bottom of the radiator what for it is necessary that the inflowing hot water upwards as described below to be led. This is also necessary on the rear radiator after the water from the front has flowed into the rear radiator.
  • An advantage at a central connection is the very long radiators Even temperature distribution, but needs hot water, which the radiator in Part load operation with a comparatively low flow velocity flows through, only that cover half the length of the radiator before it leaves the front radiator so that the side edge sections of the radiator can still feel warm.
  • Another The advantage of this connection variant is that such a radiator, especially at low outside temperatures, when cold glass surfaces above the radiator become so-called cold air rollers lead, swirled along the entire length of the radiator by inflowing warm air and can be overcompensated. So you have neither the front nor the rear end of the radiator falling cold air on your feet fear like it would be the case with a side flow connection.
  • Such a single-row radiator according to the invention has at least according to claim 9 two differently designed sections, of which a first section, which is preferred facing the room to be heated, seen in the flow direction in front of the remaining sections is arranged.

  • the respective sections according to the invention are each provided with a number of electrical heating elements (R 1 ... R n , r 1 ... r m ) which are either embedded directly in the heating element in metal bushings or in corresponding flow channels, as above described.
  • Such an electric heating element can be provided with a closed flow circuit with water, paraffin or the like, the flow convection being driven either by the heating elements themselves or by an additional drive means.
  • the heating elements of the respective sections are usually connected in parallel.
  • the individual are expedient Heating elements of the sections can be controlled individually or cascaded via a control device, so that the total heating power and in particular the proportion of heat caused by radiation and convection is dissipated, individually and adapted to the respective room conditions can be.
  • a relay (16) is also provided between the two sections (8, 9) of the radiator.
  • the first or front radiator section (8) either exclusively or additionally with a self-regulating or provide self-limiting resistance, such as in so-called self-limiting pipe trace heating is used.
  • a self-limiting resistance consists preferably of ferrites, which in a carrier material such as in a Elastomer are embedded. This results in a temperature-dependent resistance that increases with increasing temperature of the resistor, an almost step function Resistance dependence can be achieved, reducing electrical resistance is self-limited at low temperatures, for example.
  • the radiator according to the invention By dividing the radiator according to the invention into one as described above radiation section flowed first and a downstream convection section advantageous non-linear control behavior can be achieved: with low heating requirements, the Heat is preferably emitted via heat radiation, while a large one with high heating requirements Part of the heat is dissipated via convection.
  • a heater according to the invention will therefore make further improvements in the control behavior preferably with a thermostatic valve with a non-linear, for example progressive or degressive control characteristic operated.
  • the control valve is preferably designed such that that the flow through the convection section completely or partially and independently can be prevented or regulated by the regulation of the radiation section.
  • Multi-row radiators can also be used in reverse wiring, so that the Usually the radiator panel facing the room to be heated is cooler than that plate arranged behind. So you can not get your fingers on the front heating plate scald, which is already legally required in kindergartens in some countries. However, should the structural conditions such. B. the thermal insulation or Subsequent use change, so multi-row according to the invention Radiators are simply turned over, so that the warmer heating plate then the room would face, which results in the advantages mentioned above. So is one Adaptation possible without replacing or buying a radiator.
