Definitions

  • the invention relates to a radiator, in particular a flat radiator or a heating wall for the part-load operation according to the preamble of claim 1.
  • Flat radiators and heating walls are - based on the heating power - the cheapest radiator types and are characterized by advantageous decorative and hygienic properties, especially by a comparatively low mass, which has an advantageous effect on their control behavior, especially with regard to energy-saving heating systems.
  • Heating systems and thus also radiators are usually designed for extremely low outside temperatures (so-called design case), in which a pleasant room temperature is still to be provided.
  • design case As a parameter for the design of the radiator serve in particular the amount of water flowing through the radiator, the flow resistance and the ratio of the radiator sections with predominantly convective and radiant heat output. If these parameters are therefore usually tuned to extreme heating conditions, it is precisely the so-called part-load range with comparatively low heating power, which predominates over the major part of the heating period, that requires a different design and behavior of the radiator.
  • single-row radiators In order to provide the required heating power, so-called single-row radiators have a single heating plate with a substantially one-piece construction. In contrast, have two-row radiators, d. H. Radiator having a front facing the space to be heated and a plate arranged behind it, usually a symmetrical structure, wherein the front and rear heating plate is always symmetrical, d. H. with the same amount of water, is flown. This also applies to the front two heating plates of a three- or multi-row radiator.
  • said one-piece or symmetrical structure has a disadvantageous effect.
  • radiators only provide heating power of a few 100 watts, so that they are only flowed through by relatively little water.
  • the single or front the space-facing portion of a single-row radiator with convection plates will have a relatively low temperature.
  • This disadvantageous effect is exacerbated in multi-row radiators due to the symmetrical structure, because not only the front section is used for heating but also arranged behind sections. Thus, only part of the total heat is dissipated via the front heating plate.
  • the front heating plate thus remains comparatively cold.
  • the body temperature cold radiator surfaces adversely affect the indoor environment, because they are perceived as uncomfortable.
  • suddenly added to external heat sources such as irregular sunlight, suddenly switched light bulbs, ceiling spotlights or computers and additional people in the room to be heated, lead to a further reduction in the required heating power, which also very quickly at high convection of the radiator leads to cold radiator surfaces.
  • radiators designed for high heat outputs, even at extreme outside temperatures need to work almost exclusively in the partial load range.
  • radiators have been developed, which further develop the above-mentioned single or multi-row radiator while maintaining the achievable heating capacity in view of the particular conditions in the partial load range, that the space comfort is increased by the fact that the surface facing the room or at least larger sections thereof are as warm as possible in the partial load range and the radiator can be adapted in its design to a full and part load operation.
  • advantageous properties are here in particular the high heat output at relatively low heating and manufacturing costs and the good control behavior to understand, so features that directly affect the comfort and the indoor climate of the heated room.
  • Such a radiator is known for example from DE 197 29 633 C2.
  • the invention has the object to further develop the above-mentioned single or multi-row radiator while maintaining the achievable heating power in view of the particular conditions in the partial load range, that the room comfort further increases and in particular the control can be improved. According to the invention, this object is solved by the features of claim 1. Advantageous developments of the invention are contained in the accompanying claims.
  • the invention includes a radiator of the aforementioned type, with a flow connection, a return connection, a first flowed through and preferably facing the space to be heated front heating plate and at least one further flowed through and preferably arranged behind the heating plate and disposed between the upper and lower end portions of the heating plates Connecting pieces and a radiator valve for controlling the total mass flow of a heating medium, wherein the first (front) heating plate before the other (behind arranged) heating plates is flowed through substantially uniformly by a selective arrangement of shut-off devices in the connecting pieces.
  • a further radiator valve is integrated in one of the two upper connecting pieces, with which the mass flow of the Heating medium can be passed into the rear heating plate via an overflow connection.
  • the proportion of the total mass flow that enters the rear plate (s) can thus be regulated.
  • the second radiator valve is completely closed, i. all the heating medium supplied flows exclusively into the front panels, the rear panel (s) is (are) practically out of operation.
  • the second radiator valve regulates to maximum opening. In this case, all plates are flowed through in parallel.
  • the two radiator valves are arranged in one of the two upper connecting pieces, wherein the relevant connecting piece is designed as a double piece with inner obturator and has an overflow connection.
  • a radiator valve is arranged in one of the two upper connecting pieces, wherein the connecting pieces are interconnected by an overflow and each having a shut-off, with only the respective water inlet side arranged connector to the front Heating plate is formed fluid-conducting heating.
  • the two radiator valves are integrated in one of the upper connecting pieces, wherein the connecting pieces are designed as double pieces with inner shut-off and an overflow connection.
  • the upper connector is connected to the radiator valves with the respective opposite arranged in the lower end portion connecting piece via a riser, wherein the arranged in the lower end portion connecting piece is formed as a double piece with flow and return pipe.
  • a radiator valve is arranged in one of the two upper connecting pieces, wherein the upper connecting pieces are interconnected by an overflow connection (pipe).
  • the connecting pieces each have a shut-off device, wherein only the respective heating fluid inlet side arranged upper connecting piece to the front heating plate heating fluid is designed to be conductive.
  • the overflow is connected in this embodiment via a riser to the respective opposite arranged in the lower end portion connecting piece, each arranged in the lower end portion connecting piece as a double piece with flow and return pipe (VL, RL) is formed.
  • the drive and control of the radiator valve can be realized in various ways. Normally, the control and the drive via commercially available and commercially available thermostatic heads.
  • the drive can be electromotive and the control of the drive via a room thermostat. If electromotive or electrothermal drives are also used for radiator valve control, this is preferably controlled via the same room thermostat.
  • the drive can be electrothermal (electrically heated expansion chamber) and the control of the drive via a room thermostat. If electromotive or electrothermal drives are also used for radiator valve control, this is preferably controlled via the same room thermostat.
  • the drive can be carried out by an electric motor and the control of the drive via a front plate temperature difference control.
  • the teaching according to the invention provides an improved part-load principle for radiators, since in partial-load behavior, the entire power is output from the front panel (in the case of serial flow, the rear panel is also heated, if only slightly). It is an even greater warming of the front panel (more radiation, faster heating) achieved than in conventional partial load radiators, with simultaneous cold back plate (better radiation shield effect).
