Definitions

  • the object of the invention is a system for measuring the actual energy consumption of a radiator in central heating installations, designed to measure the actual amount of thermal energy flowing through the household, and also to measure the energy consumption of each individual central heating radiator regardless of the material of which the radiators are made.
  • the system enables settlement between the supplier and the energy consumer.
  • heat cost allocators are based on calculations which are variable and do not give any accuracy as to the real heat consumption of central heating radiators in column (vertical) or circular systems.
  • Current heat settlement systems are based on the indications of devices called allocators which are not measuring instruments for heat energy because they do not measure any physical quantity of heat energy consumed - most often the increase of their indications (expressed in non-indicated minimum scale intervals) depends on the ambient temperature, the temperature of the radiator's surface in the place of allocator installation and the time of heat transmission by the radiator as well as many data which should be assigned to each allocator individually.
  • the aim of the invention is to install a measuring system on each individual central heating radiator to measure the exact consumption of heat energy by each radiator, which allows for a real division of energy consumption costs into individual premises/apartments.
  • the system for measuring the actual energy consumption of a radiator in central heating installations is characterised by that the measurement of energy consumption of a single radiator is expressed in real and actual units of heat Kw/h by a digital control unit for data processing, connected by means of an electric cable with a metal part in which a flowmeter and a temperature sensor is mounted at the radiator outlet and connected by means of an electric cable with a metal ring with a temperature sensor mounted at the radiator inlet on its connection.
  • the digital control unit consists of a module in the form of an electric appliance from which data are stored in the memory of the device until reading by radio connection to the device for collective reading and data transmission.
  • the electronic module is connected by an electric cable to the second module in the form of a metal element in which a flowmeter is mounted with a temperature sensor connected to the valve on the radiator outlet by means of a radiator union, and is connected by an electric cable with the third module in the form of a metal ring with a temperature sensor mounted at the radiator inlet on the connection of the radiator's feed valve.
  • the system has a mechanical vane flowmeter equipped with rotating vanes under the influence of liquid flow, from which impulses are recorded by an electronic recording device, and a temperature probe measuring temperature of liquid outlet from the heater.
  • the electronic device module contains an electronic module of digital systems with a program to process these data into the actual heat consumption data of a central heating radiator in Kcal or kW/h.
  • the internal flow meter rim has a diameter adapted to the internal diameter of the valve and a rubber or plastic gasket applied on the rim, which, together with the radiator union, guarantees a tight connection.
  • the system measures the actual consumption of a single radiator and the information reaches a universal data receptor which converts it into figures.
  • one of the modules is a metal element, in which there is a rotary-vane or ultrasonic liquid meter and a temperature sensor which on one side has a thread allowing direct installation into the connection of the radiator, while on the other side there is a union which allows connection to the valve.
  • This module through an integrated temperature sensor built into a metal body, provides data on the heating liquid temperature at the radiator outlet, this module is connected by an electric cable to a second element in the system, which is an electronic module for receiving/sending data.
  • the third module is a metal ring with a temperature sensor mounted at the radiator inlet on the radiator's supply valve, also connected by an electric cable to the electronic module. In the case of a small water flow on the radiator inlet/outlet section (small radiators) the heat losses are negligible, then it is sufficient to base the measurement data on only one temperature measurement from a sensor located in the flow meter.
  • System components i.e. the flow meter with temperature sensor mounted at the radiator's outlet and a second temperature sensor mounted at the radiator's inlet are connected by electric cables with the electronic module.
  • This module processes data by calculating real energy consumption, the data is transferred to other information-collecting systems, or to a radio reading system for data collection and emission which transmits the consumption to the receiving central unit or data collection point and is received from there either by manual systems or by sending GSM data.
  • the advantage of the system is that it measures actual and accurate energy consumption in Kcal or kW/h units, based on a universal formula for calculating energy consumption, reads actual and real data in order to determine the consumption, not depending on the type of installed central heating radiator, its size, power and the manufacturer.
  • the system does not record heat when there is no flow because the basis for the calculation is the quantity or volume that flows through a radiator.
  • the system is used to measure heat, indicating the heat in legal units of measurement, accurately records the energy consumed in the flow and the corresponding data are based on the fact that 1 Kw/h of the universal measurement equals 859.84 kcal/h.
  • 1 Kw/h of the universal measurement equals 859.84 kcal/h.
  • radiators mounted on radiators should be subtracted from the main measurement from the boiler room or district heating substation. After subtracting the sum of all measurement readings from the main measurement from the boiler room or district heating substation, we obtain accurate data on the amount of energy actually used and energy losses that are in the installation.
  • the system can be mounted horizontally or vertically without any data loss or alteration. It can be installed in either a column or circular installation and also in single-pipe systems. If a radiator is too long for accurate reading, connect an additional temperature sensor via a ring and an additional cable in the input circuit which must be connected to the digital data receiver.

Heating fluid flows through a feed valve 6 into the radiator, its temperature is measured by a temperature sensor 7 which sends the measurement to an electronic device 4 via a cable 5. During the time when the valve 6 is open, the heating fluid flows through the radiator giving away the heat and then at the outlet from the radiator, the amount of heating fluid flow rate and temperature is measured through the flowmeter and temperature sensor 1.

This is the data of actually used Kcal or Kw/h by a central heating radiator. By summing up readings of all the radiators in an apartment/premises we get information about the actual heat consumption in the apartment/premises already expressed in Kcal or kW/h units.
