Definitions

the invention relates to a method for analyzing a pipe network of a heating system according to the preamble of patent claim 1.
a method of the type mentioned above for the analysis of a multiple heater having pipe network is according to DE 35 29 257 A1 known.
the radiator are each separated via a valve from the pipe network, wherein the pipeline network means for volume flow and pressure loss detection are provided and wherein a total flow resistance of the pipe network is composed of a number of individual flow resistances.
the pipe network is designed as a so-called Zweirohrsammlungungssystem in which the radiator are connected in parallel (a so-called Einrohrsammlungungssystem would be present if the return of a radiator would be connected to the flow of the next radiator - such systems are not interesting at this point).
the invention is in particular the object of being able to apply a method of the type mentioned above even if the network structure is unknown in itself, as for example in older houses Case is where after installation of a new boiler so-called hydraulic balancing (adjustment of the heating system such that all radiators are supplied as evenly as possible with heat transfer medium) should be performed.
radiators today typically have two valves, namely a thermostatic valve and a return fitting.
the thermostatic valve is used during the use of the radiator to set the actual desired temperature.
the bottom side arranged return screw connections are used with adjustment in order to adjust the flow area and thus ultimately a certain volume flow at a corresponding pressure loss can.
these return screw with adjustment are not sufficiently accurate adjustable or were, d. H.
the return fittings are actually only used for the basic shut-off of the radiator from the heating circuit (for example when emptying a radiator).
a thermostatic valve with integrated presetting function is used instead, wherein the presetting of the flow cross-section is carried out in the context of hydraulic balancing and then, as mentioned above, the thermostatic valve is used to set the desired temperature.
the proviso "a" valve thus ultimately expresses simply that the radiator is disconnected from the pipeline network, regardless of whether by thermostat, throttle, other valve or return fitting.
thermostatic valves are used in the measuring method according to the invention to separate the radiator from the heating circuit, the so-called thermostatic heads are because of their temperature sensitivity dismantled. On the remaining valve sockets so-called Bauschkappen or by radio or the like controllable valve actuators can then be placed.
FIG. 1 shows a pipeline network 1, wherein R1 represents the flow resistance of a first heater, R2 the flow resistance of a second heater and Rg the common flow resistance.
DV1 and DV2 are corresponding throttle valves on the radiators.
the number of measurements is k * (k + 1) / 2 for k radiators.
the combination HK1 & HK3 has the common resistance R KA .
this resistance also applies as the common resistance of the combinations HK1 & HK4, HK1 & HK5, HK2 & HK3, HK2 & HK4 and HK2 & HK5.
the combination HK1 & HK2 has the common resistance R KA + R AB .
the combinations HK3 & HK5 and HK4 & HK5 have the common resistance R KA + R AC .
the combination HK3 & HK4 has the common resistance R KA + R AC + R CD .
FIGS. 2 to 4 can be determined with this software (in the alternative by appropriate mental analysis) in particular on the basis of the common resistors that HK1 and HK2 are connected to one and HK3, HK4 and HK5 on another strand.
HK3 and HK4 are connected in parallel, with HK5 also being parallel to HK3 and HK4. This allows the entire network structure to be reconstructed on the basis of the common resistances.
the invention provides a strand regulating valve 6 on the strand for HK1 and HK2 install (see FIG. 3 ). Through this valve, a pressure drop can be realized, the height of which is dependent on the correlations throughout the hydraulic network. For example, correlations means: what is the difference between R KA + R AC and R KA + R AB ? Which volume flows are available in the design case for the individual radiators HK1 to HK5?
