Definitions

  • the invention pertains to a central heating system for heating rooms in one or more buildings with a piping network with supply and return lines, and more particularly to a system having several subcircuits, such as for heating rooms on different floors of a building.
  • Known central heating systems generally have a heat source and a pipeline system for transporting a thermal medium to heat individual rooms.
  • a thermal medium As a rule, water is used as the thermal medium.
  • the pipeline system is composed of several subcircuits which extend, for instance, in individual floors of a multistory building.
  • the subcircuits are supplied by vertical lines.
  • a subcircuit of the pipeline system consists of separate supply and return lines, at least one line barrier (i.e. check valve and/or back flow preventor) and several heating circuits parallel to one another connected to the supply and return lines.
  • a heating circuit can have only one heating element or several heating elements arranged in series and connected via supply and return lines to the supply and return lines of the subcircuit.
  • a line barrier is arranged at the start of each subcircuit.
  • the line barrier ensures a uniform distribution of water in the subcircuits. It is intended thereby to minimize irregular flow through the heating circuits and thus the heating elements because of, for instance, the long distance from the main vertical supply line or to frictional losses due to pipe curvatures.
  • valves specifically, temperature control valves, inserted into the heating circuits.
  • the valve aperture and thus the volume flow of thermal medium flowing into the heating circuits or heating elements is regulated by a pressure-sensitive actuator.
  • a spring acts in the closing direction on the actuator.
  • each heating circuit is assigned a flow limiter, which provides nearly constant pressure in the local heating circuit as it is inserted in the circuit supply or circuit return line, independently of the number of heating elements in the heating circuit.
  • a constant pressure level at the valves can thereby be guaranteed in a simple manner.
  • a heating circuit contains only one heating element or several heating elements connected in series.
  • the flow limiter in the heating circuit may be installed in the supply flow line, optionally upstream or downstream of the temperature control valve, or in the return flow line.
  • the flow limiter and the valve may be designed as an integral structural unit.
  • the installation site of the flow limiters in the individual heating circuits may be consistent or different for all subcircuits of a heating system.
  • the flow limiters are laid out such that an equally large pressure gradient is achieved at all flow limiters, independent of the existing pressure conditions and, in particular, independent of the size, number and construction of the heating elements of a heating circuit. This is important when heating elements of different size, which are supplied differing amounts of thermal medium per unit time, are employed.
  • the flow limiter is thus designed in regard to its size as a function of the size of the heating element and as a function of the pressure in the pipeline network.
  • FIG. 1 schematically shows a building 2 that has a service room 4 in a basement for accommodating a central heat source 6 and three heated stories 8 a - 8 c , namely ground floor 8 a , first upper floor 8 b and second upper floor 8 c .
  • Three subcircuits 12 a , 12 b and 12 c which are part of a central heating system 10 according to the invention, are installed in the building 2 .
  • Subcircuit 12 a extends in a ground floor 8 a
  • subcircuit 12 c in a second upper floor 8 c.
  • each heated story 8 a - 8 c , three heating circuits, a first heating circuit 32 , a second heating circuit 34 and a third heating circuit 36 , are connected to the corresponding subcircuit 12 a , 12 b and 12 c .
  • Every heating circuit 32 , 34 and 36 is connected via a supply line 24 to a subcircuit supply line 18 of the associated subcircuit 12 a - 12 c and via a return flow line 30 to a subcircuit return flow line 20 of the associated subcircuit 12 a - 12 c .
  • the first two heating circuits 32 and 34 each have one heating element 22
  • two heating elements 22 are arranged in series in the third illustrated heating circuit 36 .
  • the diameters of supply flow line 18 and return flow line 20 of each subcircuit 12 a - 12 c are identical.
  • a temperature control valve 28 for regulating the room temperature is inserted in each supply line 24 of each heating circuit 32 , 34 and 36 .
  • the flow limiter 26 is downstream of the temperature valve 28 in the supply line 24 of each heating circuit 32 , 34 and 36 , and in the subcircuit 12 b , the flow limiter 26 is upstream of the temperature control valve 28 in the supply flow line 24 of each heating circuit 32 , 34 and 36 .
  • the flow limiter 26 is inserted in the return line 30 of each heating circuit 32 , 34 and 36 and thus downstream of the temperature control valve 28 and the heating element 22 for heating circuit 32 and 34 , or both heating elements 22 , for heating circuit 36 .
