Definitions

  • the invention relates to mixed wall boilers gas, i.e. to boilers able to supply a circuit primary heating, but also a secondary water generator domestic hot water and more specifically concerns a boiler whose the primary and secondary generators are separate or separable.
  • a wall-mounted mixed gas boiler is built as know of a primary heat generator for heating comprising essentially a gas burner and its associated mechanisms gas inlet, a combustion chamber closed by an exchanger primary, a combustion product evacuation system, and a water circulation pump.
  • the evacuation system is a box draft hood in the case of an atmospheric boiler or a smoke extractor in the case of a sealed boiler.
  • the mixed boiler also includes a generator secondary for domestic hot water production, consisting of secondary exchanger, for example a plate exchanger.
  • a generator secondary for domestic hot water production consisting of secondary exchanger, for example a plate exchanger.
  • a circuit for this secondary generator is provided with a three-way valve, a sanitary water flow rate sensor, possibly a tank for micro-accumulation of domestic hot water and sensors temperature and flow rates.
  • the device if it is to be installed in a kitchen, it can sometimes be too bulky to integrate in or next to one of the closets.
  • we prefer to move the boiler away from the rooms inhabited if only to avoid on the one hand nuisance due to noise, especially when switching on the burner and the operation of the circulation pump and on the other hand all the risks linked to the circulation of gas and combustion products in a closed enclosure what some people consider it potentially dangerous and seek to avoid.
  • a boiler installed for example in a garage or a laundry room often located far from water supply points (kitchen, bathroom baths ...), which generates a waiting time to obtain hot water, and water and energy consumption increased.
  • the invention therefore makes it possible to overcome the domestic hot water circulation loops which are expensive to install and are sources of losses in electrical and thermal energy, and while providing the same service than conventional wall-hung boilers, without time waiting at the various draw-off points.
  • the invention is based on the principle of possible and modular separation of primary generators and secondary according to the technique called "split system". This technique basically involves doing at least two units for each of these two generators, these units being juxtaposed, separable and / or separated.
  • FIG. 1 shows a mixed boiler called "simple split" consisting of a first module primary heat generator as a whole designated by reference 1 and a second secondary generator module domestic hot water designated as a whole by the reference 2.
  • the execution mode does not fall within the scope of the protection covered by the independent claim.
  • the primary generator 1 essentially comprises a gas burner 10 and its gas intake mechanism 11, a combustion chamber 12 closed by a primary exchanger 13, and a hood 14 for evacuating combustion products.
  • a pump circulation 16 in which circulates the water admitted to the exchanger is interposed a pump circulation 16 and on the hot water outlet side by the conduit 18 in the direction of the arrow is placed a sensor temperature 17, the conduits (15, 18) forming the circuit heating of the primary generator.
  • an exchanger secondary 20 is installed on a short circuit 21 connected on one side to the hot water return circuit 15 and on the other side to the hot water outlet pipe 18 by through a three-way valve 22 which distributes hot water also to the starting circuit 27 heater.
  • domestic cold water is admitted to the exchanger 20 by a conduit 23 equipped with a flow sensor 24 and domestic hot water leaves the exchanger to the point of drawing from a conduit 25 fitted with a temperature sensor 26.
  • valve three-way 22 directs hot water to circuit 27. A stopping the heating request, it is repositioned on the short circuit in sanitary priority.
  • the ignition of the burner 10 intervenes to heat the water by the exchanger 13 and its rapid circulation in the circuit short 21 for domestic water heating in the secondary exchanger 20.
  • the temperature regulation is done through sensor 26.
  • the wall-mounted boiler thus consists of primary 1 and secondary 2 generators which are separable and can be installed in two places or premises geographically different from housing. So like illustrated in Figure 2, which does not fall under protection from claim 1, the generator can be integrated primary 1 in the tall units 19 of a kitchen unit standard. On the other hand, the secondary generator 2 is placed in lower part, for example under the kitchen sink 28, so as not to disturb the aesthetics of the integrated kitchen.
  • the only precaution for the primary generator is add an antifreeze product to the heating circuit.
  • Another alternative embodiment consists in use several secondary production generators domestic hot water, associated with a primary generator unique.
  • FIG. 4 schematically illustrates the assembly a boiler of this type called "multi-split".
  • Another tertiary generator designated as a whole by the reference 3 is independent of generator 2. It includes a tertiary sanitary exchanger 30 installed on a circuit short 31 connected on one side to the water return circuit primary generator 1 hot 15, and on the other hand to short circuit 21 of the secondary generator 2 by through another three-way valve 32 which is found on short circuit 21, in series with valve 22.
  • the three-way valve 32 is therefore between the latter and the secondary exchanger 20. It is designed to be able to occupy an intermediate position which allows feeding to both the short circuit 31 and the exchanger 20.
  • a stepping motor 41 is provided for the operation of the three-way valve 32.
  • domestic cold water is admitted to the exchanger 30 by a conduit 33 fitted with a flow sensor 34 and domestic hot water leaves the exchanger by a conduit 35 to a reservoir 37 with micro-accumulation equipped with a temperature sensor 36.
  • the tank 37 is maintained at temperature by a resistance electric 38 to compensate for heat losses, in connection with a bimetallic switch 39.
  • the three-way valve 22 opens towards the short circuit 21, on the other hand the three-way valve 32 is closes towards secondary exchanger 20 but opens towards short circuit 31 so that the heating water emitted by the exchanger 13 directly heats the generator tertiary 3.
  • the temperature regulation is done by via the sensor 17 placed on the primary circuit.
  • Hot water production by the sanitary exchanger tertiary 3 is done at a fixed temperature setpoint, by example 55 ° C.
  • a thermostatic valve 40 in outlet from tank 37 mixes the hot water produced at 55 ° C, with cold tap water.
  • the tank 37 to microaccumulation placed in series between the outlet of the exchanger 30 and the entry of hot water into the valve thermostatic 40 provides immediate water supply hot at the draw-off point and thus compensate for the time of temperature rise of the primary exchanger and the tertiary exchanger located at a certain distance one of the other.
  • the bimetal switch 39 linked to the tank 37 and adjusted for example at 55 ° C cuts the power supply when the temperature detected by the sensor 17 reaches 55 ° C, and restores it when it drops to 50 ° C for example.
  • this tertiary generator 3 operates without electrical connection with the primary generator 1, which avoids the tedious installation of a power line between these two modules located at a certain distance one the other.
  • valve 22 is open towards short circuit 21.
  • three-way valve 32 will go to the middle position to which the heating water is distributed to both short circuit 31 of the tertiary exchanger 30 and towards the secondary exchanger 20.
  • a stepping motor 41 for the operation of this three-way valve 32 allows a fine adjustment of the water flow in the two exchangers sanitary facilities to adjust the temperatures to the instructions appropriate, according to sensors 17 and 26.
  • FIG. 5 is an illustration of a "multi-split" installation with two generators health.
  • the primary generator 1 is located in a garage and the secondary generator 2 under the kitchen sink 28, to also serve a shower 29.
  • FIG. 6 A final example of application of the system "multi-split" is illustrated in Figure 6. It shows the installation of several primary generators 1 in one collective building. The generators are in a sheath technical on the landings of the building, near each dwelling equipped with at least one secondary generator 2 installed under the same conditions as before. A such installation authorizes the intervention of services after-sales without the need for an appointment with the occupant of the housing since maintenance of the device does not take place basically only on the burner and the combustion block of the primary generator located in the technical sheath. We thus achieves substantial cost savings boiler maintenance.
