Definitions
- the present invention relates to a hydraulic balancing device for a heating installation.
- Such an installation is equipped with a boiler or the like which makes it possible to heat a fluid which is sent via pumping means to heat emitters, in particular radiators, by a network of hydraulic pipes.
- the device according to the invention also provides thermostatic regulation of a heat emitter.
- the present invention also relates to hydraulic circuits implementing fan coil units. It adapts both to the heating circuits and to the cold water circuits used to cool the premises.
- the description below is essentially made with reference to heating circuits but it also applies to cold techniques in which a cold water network, or another fluid, is used.
- a heating installation in addition to the boiler, the radiators and the pipes, there are also regulating members which have the aim of ensuring a good distribution of the heat-transfer fluid towards the heat emitters by ensuring a sufficient flow through each of these.
- the heating circuit is balanced.
- This balancing operation consists in adjusting the various adjustment members so as to obtain flow rates previously calculated under basic conditions chosen to size different pieces of equipment of the installation operating in steady state. Admittedly, an installation hardly ever works in steady state, but this does not change the interest of the hydraulic balancing of a circuit. Indeed, if the flow rates are caused to vary during operation, this must be taken into account at the design stage and, if necessary, provide differential pressure regulators mounted in series or in parallel. This is then the domain of regulation and no longer of hydraulic balancing.
- balancing devices also called balancing members, which allow hydraulic balancing of a heating installation. These organs are intended to regulate the distribution flows in the different branches of the distribution circuits.
- non-adjustable balancing members are known. These are diaphragms, that is to say fixed calibrated orifices whose diameter is determined for each of them from knowledge of the flow / pressure drop couple to be created.
- the use of this type of member implies a complete and meticulous hydraulic calculation of all the circuits of the installation to determine precisely the characteristics of each diaphragm. In case of calculation error, there is only one solution which consists in changing the diaphragm. This solution, a priori relatively inexpensive, is therefore. very rarely used.
- adjustable balancing members known under the name, for example, of adjustment fittings or balancing valves. These members make it possible to adjust the flow rate in a circuit and therefore to balance it based on prior knowledge of the flow rate / pressure drop couple to be created. This implies a complete hydraulic calculation of the entire heating circuit. These adjustable balancing members allow the adjustment to be easily corrected in the event of an error.
- adjustable balancing members provided with a flow measurement device.
- these balancing members are equipped with a pressure tap intended for a differential pressure measurement. This measurement makes it possible to determine the flow of fluid through the balancing member.
- an electronic differential pressure gauge with microprocessor it is easy and quick to make differential pressure and flow measurements.
- This type of balancing device has a very significant advantage for the installer.
- the adjustment of the balancing member can be determined by calculation as for the adjustable balancing members described above, but the setting can also be carried out directly in situ from knowledge of the desired flow rate alone.
- this type of equipment has no direct relationship with the hydraulic balancing of the installations as defined above.
- the use of such a flow regulator can be considered as a palliative solution to the insufficiency of calculation by replacing a relatively simple static balancing member by a regulating device comprising moving parts only in order to avoid the surgery initial adjustment according to one of the procedures mentioned above.
- the use of these flow regulators is limited because, on the one hand its field of application is restricted due to the incompatibility with the thermostatic valves and, on the other hand, because of a cost of investment more higher than that of traditional solutions.

- FIG 9 shows part of an individual centralized heating circuit equipped with a balancing device according to the invention.
- Figures 1 and 2 have already been described in the preamble to this patent application.
- Figure 3 shows two circuits derived from a heating circuit.
- Each derived circuit also includes two radiators 2 mounted in parallel. In each case, they are radiators with integrated valves. However, the invention can also be applied to radiators with traditional taps. These radiators 2 are supplied with heat transfer fluid by pipes 4.
- a hydraulic module 26 allows the supply of a radiator 2 with heat transfer fluid. It incorporates a hydraulic balancing device according to the invention.
- Each branch circuit further comprises at the top and bottom each time an isolation valve 16.
- FIG. 4 shows in section and schematically a first embodiment of a hydraulic balancing member according to the invention.
- the latter has a fluid inlet 30 corresponding to a supply line 84 and a fluid outlet 32 corresponding to a return line 86.
- the device has a first adjustable orifice 34 and a second orifice 36, the opening and closing of which are regulated by a valve 38.
- the valve 38 has a head 40 and a rod 42.
- the head 40 is intended to open and close the second orifice 36. Its shape is adapted to the shape of a seat produced at the level of the second orifice 36.
- the valve rod 42 extends through a chamber 44 produced in a first body 88 of the balancing device and closed by a membrane 46.
- the body 88 contains the flow control seat 36, the corresponding valve 38, the membrane 46 and a compensating spring 56.
- One face of the membrane, that opposite to the chamber 44, is subjected to the pressure of the supply line. supply 84.
- the flow regulation seat 36 is in turn formed between the return of fluid from the radiator 2 and the return line 86.
- the membrane 46 is therefore subjected on one side to the pressure P1 and on the other side to the pressure P2.
- the compensating spring 56 is provided on the side where this lowest pressure prevails. This spring 56 surrounds the valve stem 42. It bears on the one hand on the membrane 46 and on the other hand on the body 88 at the passage 54.
- the membrane 46 is in a middle position for a difference pressure P1 -P2 given and its position varies when the pressure difference P1 -P2 varies.
- a pressure P3 prevails, itself lower than the pressure P2, taking into account the pressure drop (pressure drop) caused by the second orifice 36 and the associated valve 38.
- the pressure drops created by the radiator 2 and the rod 92 are small, even negligible, compared to the pressure drop existing between the upstream and downstream of the first orifice 34.
- a second valve 62 associated with the first orifice 34, controls the opening of the latter.
- This valve 62 is controlled by a thermostatic head 48.
- the thermostatic head 48, the valve 62 and the first orifice 34 are mounted in a second body 90 connected to the body 88 by a rod 92, which extends the supply line 84.
- the valve 62 controls the passage of fluid leaving this rod to enter the radiator 2.
- the operation of the device is as follows. It is assumed that heat transfer fluid is supplied to the inlet 30 by, for example, a pump not shown.
- the device according to the invention operates as a flow regulator.
- the pressure P1 increases, the flow rate through the device will tend to increase.
- this pressure P1 is transmitted to the right part of the membrane 46.
- This membrane then tends, under the effect of a higher pressure P1, to move to the left (with reference to FIGS. 4 and 5).
- This movement of the membrane tends to close the second orifice 36 by means of the valve 38.
- the increase in flow created by the increase in pressure P1 is therefore countered by the reduction in flow caused by the closing of the valve 38.
- the thermostatic head 48 will act on the valve 62. This will then modify the opening at the level of the first orifice 34.
- the valve 62 tends to close the first orifice 34 thus causing a drop in the flow of heat transfer fluid.
- the thermostatic head acts on the valve 62 in the direction of an opening of the orifice 34.
- the thermostatic head 48 acts on the second valve 62. If the temperature increases, the valve 62 opens, the pressure P1 remains constant while P2 increases. The first valve 38 therefore also opens, allowing a higher flow rate. On the contrary, if the temperature decreases, the valve 62 closes, the pressure P1 remains constant, the pressure P2 decreases and the valve 38 also closes. The flow through the device is decreased.
- the balancing device is identical, but in one case there is a body 88 placed in a hydraulic module 26 independent of the radiator 2 (FIG. 4) and in the other case, a body 88 placed in a module 26 integrated into the radiator 2 (FIG. 5).
- Figure 6 shows another embodiment of a body 88 intended.à equip a radiator, while being independent of this radiator.
- the body 88 here has a substantially triangular shape. At the heart of this triangle is placed the membrane 46 and the valve 38 which is associated with it. This valve is shown here in the closed position.
- the body 88 has a first inlet 102 which corresponds to the fluid inlet 30 of FIG. 4, a first fluid outlet 104 which corresponds to the outlet to the rod 92, a second inlet 106 which corresponds to the return of the radiator 2 to the body 88 and a second outlet 108 which corresponds to the outlet 32.
- a passage 1 10 is provided to directly join the inlet 102 and the outlet 104.
- One face of the membrane 46 is oriented towards this passage 1 10.
- the peripheral edge of the membrane 46 rests at the level of a shoulder 1 12. This edge is held by a ring 11 which itself is held in the body by a plug 11 16.
- An opening has been made in the body 88 facing the membrane 46 to allow the establishment of the valve 38, the membrane 46 and the plug 1 16 closes this opening.
- valve 38 With this plug 1 16 is associated a support disc 1 18 in which are formed orifices 120 so that the face of the membrane 46 facing the passage 1 10 is subjected to the pressure of the fluid passing through this passage 1 10
- the valve 38 is placed in a housing 122 in which is also disposed a guide piece 124 for the valve 38.
- the latter is for example glued to the membrane 46. It has a tubular shape and a longitudinal section of this valve has a T-shaped. The base of the T is oriented towards the second inlet 106.
- the pressure P2 which also prevails in the radiator 2.
- Figure 7 shows an embodiment of a hydraulic module corresponding to the module shown in Figure 5.
- the body 88 has a general shape in H.
- the central bar of the H houses the membrane 46 and the valve 38.
- the valve 38 is also a tubular valve provided on the side of the membrane 46 with openings 126. It is also guided in a guide piece 124.
- the originality here lies in the fact that the body is made in two parts that can pivot one relative to the other.
- a first part is referenced 88 while the other part is referenced 89.
- Part 89 carries the first inlet 102 and the second outlet 108 and is connected to the central heating network while the first part 88 is connected at the level of the first outlet 104 and from the second inlet 106 to the radiator 2.
- the part 89 has a substantially horizontal tubular part from which two tubular legs leave in which the first inlet 102 and the second outlet 108 are made.
- the substantially horizontal tubular part forms the pivot axis of the body 88 on the second part 89.
- the body 88 is made in two parts.
- the junction between these two parts is done at the membrane 46.
- this membrane is sandwiched between the two parts of the body 88.
- a fixing flange and screws are provided to allow the fixing of these two parts of the body 88. These flanges and these screws are not shown in the drawing.
- the membrane 46 seals between the two constituent parts of the body 88.
- O-rings 128 are provided for sealing between the second body 89 and the body 88.
- FIG. 8 shows an alternative embodiment for a device according to the invention. While the embodiment of FIGS. 4 and 5 is adapted to a heating circuit in which the distribution is carried out by two tubes (two-pipe distribution), the radiators being mounted in parallel between these two tubes, or in which the distribution is carried out by a tube (distribution-monotube), the radiators then being mounted in series on the tube, the embodiment of Figure 8 is suitable for centralized distribution or octopus.
- FIG 8 is a schematic view showing a circuit comprising four radiators 2.
- the distribution of heat transfer fluid is ensured from two collectors.
- a first collector 94 receives the heat transfer fluid from a boiler or other source and distributes it to the radiators 2.
- the second collector 96 collects the heat transfer fluid after the latter has passed through the radiators 2.
- Four pipes 98 leave from the first collector 94 and each connect the latter to a radiator 2, while four other pipes 100 each connect a radiator 2 to the second collector 96.
- modules 88 ' As seen in Figure 8, near the collectors 94 and 96, there are modules 88 '. These are identical to the bodies 88 of Figures 4 and 5. Therefore, the valve, the membrane and the spring contained in the modules 88 'have not been shown. We find in fact in the modules 88 'exactly the same configuration as in the bodies 88. At each radiator 2, there is a housing 90' identical to the bodies 90 of Figures 4 and 5. For the same reasons, there is the interior of the boxes 90 ′ has not been shown. The pressure drops between the modules 88 ′ and the bodies 90 ′ are greater than between the bodies 88 and 90. However, this pressure drop being substantially constant, it does not prevent flow regulation or thermal regulation.
- a module 26 as shown in Figures 6 and 7 can also be adapted to a centralized individual heating circuit.
- a heating circuit there is a primary loop, two sections of tubes 150 of which are shown in FIG. 9.
- a secondary loop 152 which in the present example comprises two radiators 2 supplied in parallel.
- the module 26 is mounted between the secondary loop and the primary loop.
- the secondary loop 152 has, downstream of the hydraulic module 26, a control valve 16 'which allows the supply or cut off of the supply to the secondary loop 152.
- a thermostatic head 48 is provided at the level of this valve 16' .
- the hydraulic module 26 associated with the valve 16 ′ and the thermostatic head 48 thus produces a balancing device according to the invention.
- each heat emitter of the installation is provided with a hydraulic balancing device according to the invention, hydraulic balancing and thermostatic regulation are automatically ensured.
- hydraulic balancing the devices according to the invention will maintain the chosen flow rate at the given set values. More precisely, each device according to the invention will maintain the flow rate between high and low limit values defined by its proportional band.
- this device is intended to replace the traditional thermostatic valve by adding an additional function, hydraulic balancing.
- the dimensioning of a radiator is done differently. Indeed, the flow circulating in the heat emitter is imposed and there is a variable temperature drop between the inlet and the outlet of the radiator. Of course, it is expected to have temperature drops which are within an acceptable range, such as for example an interval ranging from 5 to 20 degrees.
- the device according to the invention makes compatible the actions of regulating the flow and the temperature, which is not the case with existing equipment. Indeed, in the preamble to this patent application, it is explained why, in the prior art, the flow regulators are incompatible with a heating installation provided with thermostatic valves. By combining these two elements, flow regulator and thermostatic valve, in an original way, the invention makes it possible to carry out both hydraulic balancing automatically and thermostatic regulation.
- the movement of the valve or valves is controlled by a membrane and / or a thermostatic head. It is quite possible to act on the valve (s) using an electric motor controlled electronically. It is thus possible to measure the pressure difference prevailing on either side of the first orifice of the device according to the invention and to have a temperature probe for measuring the temperature of the room. These measurements are then transformed into electrical signals and, after processing by an electronic unit, a control signal is sent to an electric motor controlling the position of the corresponding valve to determine the opening thereof.
- a balancing device can be integrated into a hydraulic module which is itself integrated into a radiator. It can also find its place on a radiator in which the valves are not integrated. This device could for example be mounted in place of a thermostatic valve on a traditional radiator.
- FIG. 3 showing part of a heating circuit is given for information only. Any other configuration of the heating circuit can also be equipped with hydraulic balancing devices according to the invention.
- thermostatic valve It is enough to have an orifice creating a pressure drop. It may be a predetermined orifice, an adjustable orifice, a tap for example, or else an orifice controlled electrically by functions of various parameters.
- thermostatic head or other means making it possible to carry out a displacement as a function of the temperature
- these means can be mounted in series with the means acting as a function of the pressure difference.
- the means making it possible to carry out a displacement as a function of the temperature could then for example act on the membrane described in the exemplary embodiments described above.
