Definitions

  • the invention relates to an information system based on a heating system with multiple local supply pumps.
  • the invention further relates to a method for using such an information system.
  • LVP heating system In addition to this not insignificant energy saving potential due to the elimination of the throttle control LVP heating systems also offer other advantages, which are irrelevant to the invention. Further details of a LVP heating system, the DE 10 2006 041 345 A1 be removed.
  • the object of the invention is to systematically expand a heating system with several local supply pumps so that information about the consumption behavior and / or the indoor climate, which go beyond purely related to the operation or the control of the LVP heating system information made available ,
  • the information system according to the invention is based on a heating system with a plurality of local supply pumps, which are networked with a central processing unit.
  • the central processing unit calculates current setpoint values of operating parameters of the local supply pumps and / or receives current actual values from operating parameters of the local supply pumps.
  • additional sensor units that are not directly related to the basic operation of the heating system are coupled directly or indirectly to the central processing unit.
  • the invention makes it possible, based on the predetermined structure of a LVP heating system, to create an information system with a few additional resources, which can provide information on, among other things, the cumulative and instantaneous energy consumption in a single residential unit and / or an entire property.
  • a smart metering functionality can thus be created in a LVP heating system by using its infrastructure and an extended evaluation of the operating data of the LVP heating system in combination with the additionally available sensor data in a very efficient manner.
  • the central processing unit preferably has means for evaluating the data transmitted by the sensor units in conjunction with the setpoint / actual values of the operating parameters of the local supply pumps.
  • the invention also provides a method of using an information system according to the invention.
  • data transmitted by the sensor units are evaluated in conjunction with operating parameters of the local supply pumps.
  • FIG. 1 the basic structure of an existing LVP heating system is shown.
  • a heating system HA heats a heating medium and is also used for hot water preparation (symbolized by WW).
  • About a starting from the heating system flow line 12 more radiators 10 are supplied with the heated heating medium. After passing through the radiator 10, the heating medium is discharged into a return line 14, which in turn opens into the heating system HA.
  • Each radiator 10 is associated with a local supply pump 16, which regulates the flow of the heating medium through the respective radiator 10 individually.
  • the local supply pumps 16 are equipped with a temperature sensor T R , which continuously measures the current return temperature of the heating medium.
  • the local supply pumps 16 are provided in the example shown at the return of each radiator 10 (could in principle but also be arranged elsewhere).
  • the local supply pumps 16 are connected via a bus system or in another suitable manner (wired or wireless) to a central processing unit 18.
  • the central processing unit 18 receives current actual values of operating parameters at short intervals (for example of the order of one minute) The local supply pumps 16. These values allow a conclusion on the flow rate, which flows through the respective pump 16 and through the respective radiator 10.
  • the central processing unit 18 receives the actual return temperatures of the heating medium measured by the temperature sensors T R at the points of the individual pumps 16.
  • a control unit 20 controls local supply pumps 16 based on calculated current setpoint values of operating parameters. The setpoints are in turn based on specifications that the user of the residential unit can enter via a central operating and display unit 22.
  • Arithmetic unit 18, control unit 20 and / or operating and display unit 22 can be realized in a common device or in physically separate devices, which is basically irrelevant to the functionality of the LVP heating system.
  • computing unit comprises at least the functionalities of the arithmetic unit 18 and the control unit 20.
  • the data determined by the sensor units 24 are transmitted indirectly via the existing network of the LVP heating system to the central processing unit 18.
  • a data transmission interface 28 for receiving and / or transmitting data of the sensor units 24 is provided on one, at several or at all local supply pumps 16.
  • the data transfer interface 28 is located on the local supply pump 16 itself or on its local controller 26 (distribution box), which typically represents an endpoint of an existing bus system that connects the local supply pumps 16 to the central processing unit 18 (see FIG FIG. 3 ).
  • the data sent by the sensor units 24 on demand or continuously at short time intervals is received by one or more data transmission interfaces 28 and then forwarded to the central processing unit 18 via the existing network of the LVP heating system.
  • the transmission of the data of the sensor units 24 to the arithmetic unit 18 is based on the transmission of the operating parameters of the local supply pumps 16 to the arithmetic unit 18, in particular with regard to the short time intervals of this data transmission.
  • a method based on RFID technology For transmitting the data of the sensor units 24 to the data transmission interface or interfaces 28, a method based on RFID technology is provided, wherein the sensor units 24 are equipped with RFID repeaters. Particularly in the case of an existing suitable bus system, a local supply pump 16 acts as a master, a sensor unit 24 as a slave.
  • the data of the sensor units 24 can be retrieved by the user at any time, even in evaluated form.
  • the central arithmetic unit 18 has in particular means for evaluating the data transmitted by the sensor units 24 in conjunction with the set / actual values of the operating parameters of the local supply pumps 16.
  • the functionality of the system achievable as a result should be exemplified by additionally provided electronic heat cost allocators integrated, coupled to the radiator 10 temperature sensors are briefly explained.
  • a joint evaluation of the data of these temperature sensors together with the operating parameters of the local supply pumps 16 allows the determination of the relative (with additional knowledge of the absolute amount of energy of the entire heating system and the absolute absolute) heat quantity delivery of a radiator 10 - or any group of radiators 10 within a residential unit or property - within certain time intervals (weekly, monthly, annual intervals).
  • simple temperature sensors 30 attached to the radiators 10 are also sufficient, as in FIG. 3 shown.
  • the DIN standards for electronic heat cost allocation systems can be met directly.
  • the determination of the heat quantity deliveries makes it possible, after further recording of the necessary data regarding the primary energy expenditure (gas, electricity, fuel and / or district heat) and the operating costs of a suitable location, to carry out a complete heating billing by a billing service provider.
  • the use of RFID technology is particularly advantageous because it ensures easy identification of the temperature sensors and reliable and cost-effective communication between the sensors and the data transmission interfaces 28.
  • the display and operating device 22 can be used for interactively displaying the accumulated and instantaneous energy consumption of the residential unit in the case of appropriately integrated sensor units 24.
  • the timely and spontaneous access of the user to the essential data allowing him (possibly in an evaluated form) to disclose his current and long-term consumption behavior corresponds to smart metering functionality using the existing infrastructure of the LVP heating system.
  • a service provider can also collect up-to-date and accumulated consumption data on a larger scale, especially with regard to several residential units and properties. Users can search for one receive corresponding authentication at the service provider access to the consumption data of their housing unit, the data from the service provider to a mobile receiver (mobile phone, etc.) can be transmitted or made available via an Internet portal or in the form of an individually preconfigured website. In this way, a user z. B. verify the billing of a billing service provider.
