Definitions

  • the present invention relates to improvements and improvements to central heating installations such as that which is described and claimed in French patent n ° 86 05748 filed on April 18, 1986 in the name of the present applicant.
  • the installation described in this patent comprises a boiler, a two-way switch valve at the end of the water supply pipe from the boiler, a first loop supplying a first heating device at moderate temperature and high inertia. and a second loop supplying a second heating device with higher temperature and low inertia. It further comprises a control member controlled by means sensitive to the ambient temperature of the areas where these heating devices are installed and by aquastats provided on the high inertia loop and on the outlet pipe of the boiler.
  • the switch valve establishes the circulation of hot water from the boiler in the high inertia loop and, when there is a request from the low inertia loop, it switches the circulation of hot water to this loop, interrupting circulation in the high inertia loop.
  • the latter is therefore no longer supplied with hot water, but, because of its high inertia, remains at a sufficient temperature.
  • the high inertia loop being made up of several heating elements, it can result from heat accumulations in some of these elements, which can be a disadvantage with regard to the heating comfort of the installation.
  • the object of the present invention is to remedy this drawback by ensuring continuous circulation in the high inertia loop independent of the circulation of hot water from the boiler.
  • the invention therefore relates to an improvement to the central heating installation according to one of claims 1 to 4 of patent n ° 86 05748.
  • the first loop further comprises a circulator mounted between the first outlet of the switching valve and the inlet manifold of the first heating device.
  • a pressure-breaker bottle is provided between the boiler and the first loop, this bottle comprising, on the boiler side, an inlet connected to the first outlet of the switch valve and an outlet connected to the return line from the boiler and, on the loop side, an outlet connected to the inlet manifold of the first heating device and an inlet connected to the return manifold of said device.
  • the routing valve is a two-way valve with three positions, the first way being connected to the first loop and the second way to the second loop, and, in a first position, the first channel is open to allow the circulation of water from the boiler feed pipe to the first loop, in a second position, from said pipe to the second loop, and in a third position, from said pipe to the two loops, this valve being piloted by a circuit which keeps it at rest in the second position, said circuit comprising three inputs, the first of which receives a predetermined voltage to control the opening of the first channel of the valve, the second a predetermined voltage to control the closing of the second channel and the third a reference supply voltage, the first voltage being supplied when the contacts of the first er means of regulation and that of the aquastat of the first loop are closed, the second when the contacts of the first regulating means, that of the aquastat of the first loop as well as that of the second regulating means are closed.
  • the contact of the second regulating means is mounted in series with a relay with one working contact and two break contacts, the working contact is mounted in series with control of the boiler burner and an aquastat provided on the second loop, the first rest contact is mounted in series with the first regulating means, the aquastat of the first loop and the boiler burner, the second contact rest being connected, on the one hand, to the first input of the valve control circuit and, on the other hand, to the phase wire via the first regulating means and the aquastat of the first loop, the second input being itself connected to the phase via the first regulating means and the aquastat of the first loop, the third input being connected to the neutral.
  • a water outlet pipe 2 with a temperature limiter 3 comes out.
  • a switching valve 4 At the end of the pipe 2 there is a switching valve 4.
  • a boiler arrives water return line 5 comprising an accelerator 6.
  • a channel 4 ′ of the valve 4 is connected to a first inlet 20 of a pressure relief bottle 21, a first outlet 22 of which is connected to the line 5 returning to the boiler 1.
  • a first loop 7 comprising an aquastat 8, an accelerator 14, a collector 9 and, between the collector 9 and a return collector 5 ′ connected to a second inlet 24 of the bottle 21, a plurality of '' organs heating such as heated floors PC1, PC2, ..., PCn.
  • Fig. 1 only three heating elements PC1, PC2 and PC3 have been shown.
  • the members PC1 to PCn are mounted in parallel.
  • the set of heating elements PC1 to PCn includes a means REG1 sensitive to the ambient temperature of the zone where it is installed.
  • a second loop 10 comprising a flow collector 11 and a plurality of heating such as radiators R1, ..., Rn.
  • these heating members are three in number.
  • the radiators R1 to Rn are mounted in parallel between the collector 11 and the return collector 5 ⁇ .
  • the loop 10 also includes a means REG2 sensitive to the ambient temperature of the area where it is installed. Between the valve 4 and the manifold 11 is mounted an aquastat 3 ′.
  • the valve 4 is preferably a two-way, three-position valve. In a first position, the water circulates only from line 2 to track 4 ′, in a second position, only to track 4 ⁇ and, in a third position, to both tracks 4 ′ and 4 ⁇ at the same time .
  • the valve 4 is controlled in one of these three positions by means of a circuit 12.
  • Fig. 2 represents the circuit which performs, on the one hand, the control of the burner of the boiler 1 and, on the other hand, the control of the valve 4.
  • the contact of the means REG2 is mounted in series with a relay K between the wire neutral N and the phase wire P.
  • Relay K has a working contact K1 and two break contacts K2 and K3. With the contact K1, are mounted in series between the wires N and P the contact of the aquastat 3 ′ of the loop 10 and the burner control 13. With the control 13, are also mounted in series between the wires P and N , on the one hand, an assembly consisting of the contact of the means REG1 and that of the aquastat 8 connected in series and, on the other hand, the rest contact K2.
  • REG1 At the common point between the contact K2 and all of the contacts 8, REG1, is connected a first input 12 ′ of the circuit 12 for controlling the valve 4 and, via the rest contact K3, a second input 12 ⁇ of circuit 12.
  • the latter has a third input 12 ′′′ connected to the neutral wire N for its supply.
  • the installation according to the invention operates as follows. When there is no request from loop 10, the contact of the regulating means REG2 is open. The relay is therefore not supplied. Contact K1 is open and contacts K2 and K3 are closed. If there is also no request from the loop 7, the contact of the means REG1 is open. The control 13 and the circuit 12 are not activated. Thus, the valve 4 is at rest and the water circulates only in the loop 10 and the heating elements R1 to Rn.
  • the contacts of the means REG1 and of the aquastat 8 are closed.
  • the contacts K2 and K3 being closed, the control of the burner 13 is activated.
  • the inputs 12 ′ and 12 ⁇ are at the potential of the wire P and the valve 4 is in the first position, that is to say open on channel 4 ′ and closed on channel 4 ⁇ .
  • the water from the boiler therefore circulates in the bottle 21 where it exchanges its heat with the water which itself circulates, by means of the accelerator 14, in the loop 7.
  • the temperature of the water in the loop 7 is limited to a set temperature given by the aquastat 8 which controls the burner 13.
  • the contact of the means REG2 is closed and the relay K is energized.
  • Contacts K2 and K3 are open and contact K1 is closed.
  • Input 12 ′ is always supplied, but more input 12 ⁇ .
  • the valve 4 is therefore in its third position in which it is open both on track 4 ′ and track 4 ⁇ .
  • the water circulates at the same time in the loop 7 and the bottle 21 and the loop 7.
  • the control of the burner 13 is cut off, unless the temperature of the water in the loop 10 is lower than a given set temperature. In this case, the contact of the aquastat 3 ′ is closed, which activates the command 13.
  • the contact of the means REG2 is closed and the relay K is energized.
  • Contact K1 is closed and contacts K2 and K3 are open.
  • the inputs 12 ′ and 12 ⁇ are therefore not supplied and the valve 4 is at rest in the second position.
  • Track 4 ′ is closed while track 4 ⁇ is open.
  • the water therefore circulates in the only loop 10.
  • the contact of the aquastat 3 ′ closes and the control 13 is activated. Otherwise, the contact of the aquastat 3 ′ is open and the control of the burner 13 is not activated.
  • the bottle 21 serves to break the circulation pressure in this loop, both when the water circulates and when it does not circulate from the valve 4 to the return line 5.
  • the bottle also serves as an exchanger between the water of the boiler and that of the loop 7.
  • control circuit shown in FIG. 2 is controlled by a microprocessor which receives the signals from the contacts of the regulating means REG1, REG2 and the aquastats 3 ′, 8 and which controls the control of the burner 13 and that of the three-position valve 4.
