Definitions

  • the invention relates to a room air conditioning system for buildings, wherein it this air conditioning system is a central heating system or a central cooling system can act, for example, as a cooling ceiling system is realized.
  • Every radiator is controlled with a locally regulated one Thermostats equipped. This is used to control the temperature of each To keep space constant. At the same time have heating systems via a central control, both the flow temperature and the Pump. This central regulation generally also represents a change the temperature profile over time ready to the room temperatures adapt to the requirements of the room users.
  • the invention has for its object a room air conditioning system for buildings with a central setpoint for each Valve is possible without the need for additional lines for communication with the valves are required.
  • the heat or cold is transported Medium also for the transmission of information to the local valves or valve control units and in a preferred embodiment of the invention also for the energy supply of these local valve units used.
  • Communication with each valve is possible from a central office be either selective or broadcast with everyone Valves at the same time and together. The possibility of selective individual communication sets certain signal loads on the side of the valves processing units ahead, which will be discussed later.
  • each pressure sensor is a hydraulic actuator, which is a function of the pressure of the medium has adjustable sensor element, which with the actuator is mechanically coupled to adjust the valve.
  • the actuator itself is mechanically coupled to the valve. Is it the Valves around the commercially available thermostatic control valves, so that can Actuate actuator on the valve tappet or sensor pin, which ultimately also the manually adjustable regulating head of the thermostatic attachment acts. So you could, for example, depend on that between yourself adjustment element of the regulating head that changes from the room temperature and the feeler pin an eccentric disc or another the distance between integrating these two elements changing unit that is controlled by the pressure of the medium.
  • the pressure sensors are either directly or indirectly from the medium pressurized. In the latter case, the pressure sensors are in Contact with components of the valve, which in turn the pressure of the medium are exposed. For example, media printing through which the flow of the heat exchanger (e.g. radiator) influencing the valve body of the Valve are detected.
  • the heat exchanger e.g. radiator
  • the extendable sensor element depending on the pressure of the medium expediently takes depending on which pressure ranges the media print is in defined states. This can be achieved by appropriate biasing of the sensor element. With these prestresses, one could, for example, achieve that Sensor element with a system pressure up to 1.5 bar a first position and assumes a second position at a system pressure between 1.5 and 2.0 bar.
  • the quantization can also be carried out in a finer and more diverse manner become, i.e. more than two pressure ranges can also be defined, in which the sensor element then correspondingly many different positions occupies.
  • valves Due to the type of control of the valves described above the actuators acting on the valve body make it possible to control the valves centrally to be set differently for day and night operation. So could a different system pressure during the day, for example build up than during the night. These pressure differences are either by operating the feed pump of the system differently or by achieved a pressure reducing device operating in different operating conditions is working.
  • each in a room air conditioning system To be able to control the valve separately, including commands, of course can be sent that affect all valves (broadcast mode).
  • the individual control of the valves requires that the time variable pressure build-up and thus the temporal pressure fluctuations of the Medium is "recognized" by the individual control units, so that one Control unit to which a specific pressure fluctuation pattern is assigned, when this pressure fluctuation pattern is recognized, then using the following Pressure fluctuations adjust themselves accordingly. So it has to a defined protocol exists, via which commands are then sent to the local control units are transmitted. This protocol defines the temporal variation of sound propagation through the system, which is preferred should be very low frequency so as not to cause acoustic interference is coming. The pattern of sound propagation, i.e.
  • the pattern of pressure fluctuations in the medium includes a defined beginning and a defined one End, whereby after the beginning a first sequence of pressure fluctuations that contains the necessary address information.
  • An address recognition device is assigned to each control unit an address comparison based on the signals implemented by the pressure sensor makes. Another follows the address pressure fluctuation sequence Sequence of pressure fluctuations, that of the actuation of that actuator serves that is specified by the address.
  • individual valves, groups of valves or all valves be addressed. Communication between the control center and the valves is done according to the same protocol rules as with other bus-controlled Systems, with the difference that according to the invention for the Control of air conditioning systems for communication Heat or cold transport system is used.
  • FIG. 1 shows part of a central heating system 10 with a heating boiler 12 and a pipeline consisting of a flow pipe string 14 and a return pipe string 16. From the feed pipe string 14 At 18, the leads to the individual branches in this case as radiators 20 shown heat exchangers, with between the branch points 18 and the radiators 20 control units 22 are connected. In the direction of flow behind the radiators 20, these are with the return pipe string 16 connected, which is indicated at 24.
  • the central heating system 10 has a media pressure setting device 26 provided with which the pressure of the heat medium, which in the simplest case is water, is adjustable.
  • the Media pressure setting device 26 is, for example, as a pressure reducing device 28 realized, which is adjustable and controlled via an actuator 30 becomes.
  • This actuator 30 is in turn from a central Control unit 32 controlled.
  • the control is time-dependent, so that for example, during the day the media print in a first Printing area is at one, while media printing at night is set in a second pressure range.
  • control units 22 to the different operating pressure of the Can react medium, they are designed, for example, according to FIG. 2.
  • These control units 22 are basically the same as commercially available Thermostatic control valves 34 built, but not only by the adjustable by turning the handwheel cap 36 of the regulating head 38
  • Thermostatic tappet 40 on the connected to the valve body 42
  • Valve tappet 44 of the lower valve part 46 is acted, but additionally there is also the possibility that this valve tappet 44 is also dependent can be moved by the media print.
  • the control unit 22 supplemented by a pressure sensor 48, which is exposed to the medium Has sensor element 50.
  • This sensor element 50 is by a spring biased to a certain minimum pressure, so it just moves when this minimum pressure is exceeded.
  • Fig. 3 shows the structure of a central heating 10 'compared to the central heating 10 is more comfortable than the piping of the radiators 20 from the central control unit 32 selectively with each one Control unit 22 ', individual groups of control units 22' or all Control units 22 'can be communicated simultaneously.
  • the basic structure of the central heating system 10 ' is comparable to that of the central heating 10, but the nature of the change in Pressure of the medium is different.
  • the central control unit 32 namely controls the actuator 30 for the pressure generating element 60 Media pressure generating device 26 according to a predetermined protocol on, so that, even if low-frequency, pressure fluctuations are impressed be different for the transmission of different information show temporal patterns.
  • address identification data are first transmitted to a or to be able to select several specific control units 22 '. In one of them Subsequent phase of the pressure fluctuation sequence are then setting data sent to the selected control units 22 '.
  • the encryption the address data and the setting data are thus made by stamping the pressure fluctuations, either by temporal or Amplitude modulation.
  • FIG. 4 A control unit 22 'which can be used in the central heating system 10' is shown in FIG Fig. 4 is shown schematically.
  • the mechanical structure of the thermostatic control valve 34 is except for the fact that on the valve lifter 44th is acted on electromechanically, same as the structure of the thermostatic control valve 34 of FIG. 2. In this respect, the same reference symbols are used in FIG. 4 been used.
  • the pressure sensor 62 used in the control valve unit 22 works as hydroelectric converter that converts the pressure of the medium into an electrical one Converts signal.
  • the pressure sensor 62 can be a Have sensor element 64 exposed to medium pressure to generate electrical energy or an electrical signal mechanically on a piezo element 66 acts. If the sensor element 64 becomes pressure fluctuations over time exposed, they are reflected in that of the piezo element 66 generated electrical signal again.
  • the piezo element 66 is a Line 68 connected to a converter 70, the output signal of the Piezo element 66 in a signal for feeding a power supply source 72 implements.
  • the converter 70 and the power supply source 72 connected to one another via a line 74.
  • a part of Energy of the electrical signal of the piezo element 66 is in an address recognition device 76 used to recognize the address data, which in the first part of a sequence of pressure fluctuations are transmitted via the medium and thus also in the first part of the electrical signal of the piezo element 66 appear.
  • a control unit 78 which is an actuator 80 controls.
  • This actuator 80 is an electromechanical actuator executed and can include, for example, an actuator, the with one arranged between the thermostatic tappet 40 and the valve tappet 44 Cam is coupled to twist the same.
