Definitions

  • the invention relates to a central heating system for heating Spaces according to the in the preamble of the claim 1 specified Art.
  • the known central heating systems generally have a heat source and a piping system for transportation a heat transfer medium to the individual rooms.
  • Heat transfer medium is usually water.
  • a sub-branch of the pipe system usually exists from separate supply and return lines, at least one string lock and several each parallel to each other switched, connected to the supply and return lines Heating sections.
  • a heating element can only do this one radiator or several in a row have switched radiators, which and drain lines with the supply and return lines of the branch are connected.
  • each branch In the flow line is at the beginning of each branch arranged a string lock.
  • the strand lock ensures an even water distribution in the Part strands. Uneven flow through the heating lines and thus the radiator with the heat transfer medium due to e.g. B. long distance from the riser, or friction losses due to pipe bends be minimized.
  • the regulation or control of the desired room temperature takes place via the in the heating strands Valves, in particular thermostats.
  • the valve opening and thus the one flowing into the heating strands or radiators Volume flow of the heat transfer medium is about one pressure-sensitive actuator controlled.
  • On the actuator a spring acts in the closing direction.
  • the known central heating systems have the disadvantage that the built-in string locks, depending on the flow rate, cause different pressure drops.
  • the hysteresis of the valves increases or shifts yourself, especially the individual temperature setting of the individual rooms is not guaranteed.
  • the invention has for its object a central heating for rooms to be heated according to the in the preamble of the type specified in claim 1, that while avoiding the above Disadvantages with simple construction an energy saving is achieved.
  • This task is characterized by the characteristics of claim 1 in connection with its preamble features solved.
  • the invention is based on the finding that through Setting an almost constant pressure level in the Pipe system of the heating system, especially to the Valves, a high energy saving and lowering the Operating costs are possible.
  • each heating element is therefore independent the number of radiators in the heating element, a flow limiter assigned to the Inlet or outlet line is introduced.
  • a constant pressure level can be applied to the Valves are guaranteed.
  • heating element is only one Radiators or several radiators connected in series contains.
  • the installation of the flow restrictor in the Heating line can be either in the supply line, optionally before or after a valve, as well as in the drain line, respectively.
  • the flow limiter and the valve is designed as a structural unit.
  • the flow limiters are dimensioned so that they are independent of the existing pressure conditions in the Heating system and especially regardless of size, Number and type of radiators in a heating system same size on all flow limiters Pressure drop is realized.
  • the installation location of the flow limiter in the individual Partial strands of a heating system can be used for all strands be uniform or different.
  • the flow limiters become interchangeable in the pipe network brought in.
  • Flow limiter designed so that regardless of the present pressure conditions and in particular regardless of the size, number and type of radiators a heating line at all flow limiters an equally large pressure drop is realized. This is important if different sized radiators are used be from different amounts of heat transfer media flow through per unit of time.
  • the flow limiter is therefore dependent on its size the size of the radiator and depending of the pressure in the pipeline network.
  • a building 2 is shown schematically in FIG. 1, the an economic area 4 in the basement for recording the heat source 6 and three heated floors 8a to 8c comprises, namely ground floor 8a, first floor 8b and second floor 8c.
  • the building 2 are introduced three sub-strands 12a to 12c, which are part of a Central heating 10 according to the invention.
  • the Partial strand 12a extends on the ground floor 8a, the Branch 12b on the first floor 8b and the branch 12c on the second floor 8c.
  • the sub-strands 12a to 12c each have a flow line 18 and a return line 20, which are separated run from each other. Via the risers 14 and 16, which also have a forward and reverse have, the sub-strands 12a to 12c with the Heat source 6 connected.
  • each heating section 32 to 36 is included an inlet line 24 to the supply line 18 of the assigned Substrands 12a to 12c and a drain line 30 to the return 20 of the assigned partial strand 12a connected up to 12c.
  • the first two heating lines 32 and 34 each have only one radiator 22, are in the third heating branch 36 shown two radiators 22 arranged in series.
  • the pipe diameter of the supply line 18 and return line 20 of a partial strand 12a to 12c are identical.
  • thermostatic valve 28 for controlling the Introduced room temperature.
  • each heating line 32 is a flow limiter 26 built-in.
  • the location of the flow restrictor 26 in the inlet line 24 or the outlet line 30 one each heating line 32 to 36 is within a partial line 12a to 12c uniform, but the installation location different for each of the three Sub-strands 12a to 12c.
  • branch 12a is in everyone Thompsonstrang 32 to 36 of the flow limiter 26 in the Inlet line 24 downstream of the thermostatic valve 28 and in sub-branch 12b there are 32 to 36 in each heating branch the flow limiter 26 in the feed line 24 to the Thermostatic valve 28 upstream.
  • the branch 12c is the flow limiter in each heating section 32 to 36 26 introduced into the drain line 30 and thus the thermostatic valve 28 and the radiator 22nd or downstream of the radiators 22.
  • thermostatic valves mostly open 28 there are different in the central heating 10 high flow rates of the heat transfer medium.
  • the flow limiter 26 in the inlet line 24 or outlet line 30 of each Schustranges 32 to 36 essentially arises constant flow rate in the central heating 10 a.
  • the now essentially constant Flow rates become pressure fluctuations within the central heating system 10, in particular in the inlet lines 24 and outlet lines 30 of each heating line 32 and thus on the thermostatic valves 28 avoided. Consequently the hysteresis of the thermostatic valves 28 remains in relation unchanged to each other. This has the advantage that the Room temperature is controlled more precisely, thus a manual one It is no longer necessary to readjust the room temperature and consequently energy savings can be achieved.
  • the invention is characterized in that through the decentralized installation of flow limiters in the inlet line 24, optionally before or after the thermostatic valve 24, or in the drain line 30 of each Schustranges 32 can save considerable energy.
