Definitions

  • the invention relates to a method and a system for detecting the hydraulic state of a heating system with a fluid flow system connected to radiators, which are flowed through by a heating medium having a flow temperature.
  • valve authority stroke position and flow or heat output of the radiator is exemplary in the Fig. 2 and Fig. 3 shown.
  • values above 0.3 for the valve authority should be aimed for.
  • a method for automatically achieving a hydraulic balancing is known in which the radiator thermostatic valves are initially fully opened and the resulting temperature in each room is measured. In rooms where the resulting temperature is too high, the thermostatic valves are closed until the desired temperature is reached. The degree of opening of the thermostatic valves determined in this way is used as the maximum opening for all other control activities.
  • the method is used to determine hydraulically undersupplied radiators, but has the disadvantage that the thermostatic valves of all radiators must be operated and therefore the apartment must be entered, Furthermore, the stationary state of the plant is waiting to be evaluated before an evaluation. This is particularly disadvantageous because of the manual access. Also, it can lead to misjudgments in the implementation of the method, as one too high room temperature can also set due to incorrectly dimensioned radiator. This would be erroneously attributed to hydraulic balancing by this procedure.
  • the object of the present invention is firstly to gain reliable knowledge of the hydraulic state of the heating system and preferably of the hydraulically poorly supplied radiators, in order to be able to initiate the correct measures in a targeted manner without an inspection of the automatic determination of the hydraulic state the apartments or the building would be necessary.
  • the heat demand of a radiator during operation indicates characteristic values for a hydraulic undersupply a characteristic behavior that can be differentiated from a hydraulically well supplied condition.
  • the logarithmic radiator overtemperature, the difference between radiator side air and room air side radiator temperature or the difference between the radiator surface temperature and the room air temperature can be used as a parameter.
  • These excess temperatures which are all characterized by a difference between the radiator side and room air side temperatures, are a measure of how much heat the radiator dissipates to the environment.
  • the radiator operating power ratio determined from the current radiator output and the radiator output at nominal mass flow and actual flow temperature can be used as a parameter, which can be determined particularly simply from the current logarithmic overtemperature and the logarithmic overtemperature at the standard point. As will be explained in detail later, it has been found that the operating power ratio offers a particularly significant possibility for assessing the hydraulic situation of a heating system.
  • the characteristic curve establishes a relationship between the operating power ratio and a radiator supply state in a heat adaptation control in which a control upstream of the actual heater control is pre-regulated to the one set value of a radiator supply state and an operating duty ratio, respectively.
  • the radiator supply state and the radiator operation ratio may also be in accordance with the characteristics of FIG Fig. 5 be taken as a function of the logarithmic overtemperature.
  • radiator operating power ratios BLV
  • radiator supply states VZ
  • GBLV heating circuit or building operating ratio
  • LV heating circuit or building supply state
  • the logarithmic excess temperature and the operating power ratio or the radiator supply state can both be evaluated in their time trend in order to allow an even more reliable statement about the hydraulic state of the heating system.
  • the change of the characteristic quantities can be generated via gradient formation or ratios of the differences, the latter being the simpler way in practice because the measured values are present in each case and in a simple arithmetic operation even in non-expensive ones Arithmetic units, such as simple microprocessors, can be deducted from each other. Frequently, the analytical formulas for forming the derivatives are not known or a numerical gradient formation is too expensive.
  • the changes of the parameters can be averaged over time, for example.
  • a particularly simple criterion for the trend evaluation of the parameter is to compare the change in the parameters over time or the flow temperature with specified characteristic or threshold values in order to distinguish a hydraulically adequately supplied state from a hydraulically undersupplied state.
  • characteristic or threshold values can be well determined, as will be shown later.
  • a state table with the states of the hydraulic supply of the individual radiators and / or the hydraulic supply of the entire heating system can be created. This can be displayed in an information unit, a service center of the heating cost detection system and / or a heat capacity adaptation control.
  • the service center from the states of the hydraulic supply of the individual radiator can derive the states of the hydraulic supply of the entire heating system by calculation rules.
  • the invention further relates to a device for detecting the hydraulic state of a heating system with connected via a fluid flow system radiators, which flows through a heating medium with a flow temperature
  • the device is equipped with at least one connection for inputting the flow temperature, at least one connection for inputting a heater-side temperature and at least one connection for inputting a room-air-side temperature and a computing unit, which is set up from the entered temperature values to determine at least one of the heat demand of the radiator indicating characteristic and to evaluate the change in the parameter over time or over the flow temperature and the temporal change of the flow temperature.
  • the arithmetic unit is set up to carry out the described method according to the invention.
  • a plurality of connections for inputting temperatures are formed in the device as a common connection to a heat cost allocator, with which the or a part of the required temperature values are detected.
  • the heat cost allocator already transfers an excess temperature or other processed characteristic or intermediate size instead of the individual temperature values.
  • the device according to the invention may have connections for several heat cost allocators. Then, with the proposed device, the method according to the invention for detecting the hydraulic balancing can be carried out in a central device, which has, for example, only one connection for a centrally measured flow temperature. Of course, it is also possible to provide in such a central device several connections for measured in the flow of a radiator flow temperatures.
  • the device according to the invention can be integrated in a heat cost allocator that can be attached, in particular, to a radiator.
  • a heat cost allocator that can be attached, in particular, to a radiator.
  • This allows the hydraulic balancing to be determined decentrally and can be combined, for example, in a service center.
  • a service center can serve the visualization of the respective status data.
  • the device may have a connection for the output of determined hydraulic states of a single radiator or the entire system.
  • the device proposed according to the invention is not limited thereto, it is particularly advantageous to design some or all of the connections as radio communication connections. Then, the proposed system for detecting the hydraulic state can be particularly easily integrated into radio systems for heating cost distribution, because the radio telegrams emitted by Funksammlung Jardineckecker or correspondingly suitable temperature sensors can be easily detected in addition by the inventive device.

  • a radiator valve 1 can be opened maximum.
  • the hydraulic flow conditions are different, so that even with a maximum open radiator valve 1 does not flow the same mass flow through each radiator 2.
  • this is not desirable because then the disadvantaged in the hydraulic system radiator 2 does not reach the required heat output. Therefore, the maximum flow rate through hydraulically-preferred radiators 2 is provided with thermostatic valves 1 (ie, 1a.1b; 1c, 1d; 1e, 1f) with preset (KVS value) and / or throttle valves 3 provided on each radiator return (ie, 3a , 3b, 3c, 3d, 3e, 3f) in favor of the hydraulically disadvantaged radiator 2 limited.
  • This leads to a higher differential pressure in the hydraulically disadvantaged radiators 2 and with optimal setting to the fact that the desired heat output can be delivered to all radiators 2.
