  • the direct exchanger can be supported cantilever in the ball.
  • the direct exchanger and the tank can be arranged substantially vertically, the first preferably at the bottom in the second, and so that the support piece constitutes a bottom of the balloon and includes means, such as a fourth tubular nozzle, for connection watertight with a partial domestic hot water collection tube high in the balloon, and with said drawing outlet.
  • This embodiment is advantageously combined with the use of a plate heat exchanger with primary and secondary inputs and outputs are provided in a single end portion of the direct exchanger, entering primary and leaving secondary advantageously leading in an external side wall of this direct exchanger, while the leaving primary and entering secondary advantageously lead into the opposite external side wall of this direct exchanger.
  • the invention relates essentially to this auxiliary heat exchanger E.
  • the tank 10 and the plate heat exchanger 14 are mounted as follows : the primary 15 of the plate heat exchanger 14, on the section 6 of the circuit DHW 4, 5, 6, is directly supplied by the tubing 4 of the main exchanger 2, through the three-way two-way valve 21 (the function of which is explained below), when the valve 21 is in the position shown in Figure 1.
  • the primary of the heat exchanger auxiliary E is therefore essentially constituted by the primary 15 of the plate exchanger 14.
  • the secondary 9 of the heat exchanger auxiliary E it is made up in series, from upstream to downstream, i.e. the cold water inlet 7 to the hot water outlet 8, through the secondary 16 of the plate heat exchanger 14 and by the volume of water inside the tank 10 and around the plate exchanger 14, the secondary 16 outlet of the exchanger 14 emerging at a low point 12 directly in the balloon 10.
  • the plate exchanger 14 is mounted upstream by compared to balloon 10 on the drawing circuit 7, 9, 8.
  • the water cold sanitary entering the drawing circuit by the inlet 7 cross first the secondary 16 of the exchanger 14 then the internal volume of the tank 10, so that it is heated by thermal transfer between the primary 15 and the secondary 16 of the plate heat exchanger 14, and this heated domestic water is mixture with that contained in the flask 10 and then flows through the tube 11 to outlet 8 for domestic hot water.
  • FIG. 1 several bodies or assemblies outside the casing 1 and also connected to the circuits described above are also shown.
  • FIG. 1 also shows a safety valve 22, connected to the hot water outlet 8, a flow meter 23, mounted on the water inlet cold 7, and a temperature probe 24 mounted in the tank 10.
  • the temperature probe 24 can be arranged in or at close to exit 12 of secondary 16 of the plate heat exchanger 14, and supported by the latter or by support and positioning parts of the exchanger 14 in the tank 10, and the probe 24 can be seconded by a another temperature sensor (not shown in Figure 1) in or near immediately from the entrance to secondary 16 of exchanger 14.
  • the flow meter 23 and the probe (s) such as 24 are associated, as described in FR-A-2742214 and EP-A-0778450, has means for controlling the power calorific released by the boiler 2-3-4 with flow and temperature parameters detected, according to an advantageous mode of action described in the documents cited above, to which reference may be made for further details on this subject.
  • the burner 3 is turned on operating at a maximum speed or at a reduced speed depending on whether the flow of water detected by the flow meter 23 is above or below a threshold of setpoint.
  • the tap 18 is closed, the burner 3 is turned off and the pump 5 stopped, and the tank 10 contains a supply of sanitary water at a sufficient temperature, for example of the order of 60 °, to meet the needs for drawing domestic hot water.
  • the opening of tap 18 is of no consequence as long as the temperature of the water in the tank 10 remains above the set point. Hot water from tank 10 and drawn by the tube 11 is replaced by cold water coming from the inlet 7, so that the temperature of the water reserve in the tank 10 decreases gradually.
  • the pump 5 is put into operation and the burner 3 lit, at a speed which depends on the drawing flow, detected by the flow meter 23, the power thermal released by the burner 3 being maximum or reduced depending on whether the threshold flow setpoint is exceeded or not by the drawing flow, the operation pump 5 and burner 3 as well as hot water circulation in the domestic heating circuit being maintained for the entire duration of the drawdown considered.
  • the water from drawing first crosses secondary 16 of exchanger 14 before reaching in the tank 10, and, due to the higher temperature of the heating water passing through the primary 15 of the exchanger 14, the drawing water is heated in secondary 16 of exchanger 14 before its introduction into the tank 10, which does not substantially cool the domestic hot water in reserve in this tank 10, and the temperature of the domestic hot water drawn can remain at a sufficient value during all the drawing, and even beyond a drawing time corresponding to a total volume distribution in reserve in the tank 10.
  • the location of the secondary 16 of the exchanger 14 upstream of the tank 10 on the domestic water drawing circuit not only minimizes the introduction of cold water into the tank 10, which is harmful the temperature resistance of the water reserve contained in this tank 10, but also avoids the risks of overheating of the drawn water, since the sanitary water leaving secondary 16 of the plate exchanger 14 is mixed with the water in reserve in the tank 10 before reaching the tap 18.
  • the heating water circulating in the primary 15 of the exchanger 14 is never brought to a very high temperature, which avoids risks scaling of primary 15, because in the absence of drawing, the burner appearance 3 is moderate when in use, and calories from the main exchanger 2, 3, 4 are mainly distributed to sanitary water in the flask 10 by heat exchange with the heating water in the primary 15 of exchanger 14, through the external walls of this exchanger 14, while in drawing mode, the burner 3 has a moderate pace or maximum, the calories from the main heat exchanger 2, 3, 4 are mainly transmitted to sanitary water in the secondary of exchanger 14, by thermal transfer from the heating water in the primary 15 of this exchanger 14, a calorific contribution limited to the water in the remaining tank 10 provided through the external walls of the exchanger 14.
  • the plate exchanger 14 of FIGS. 2a and 2b comprises an assembly of six plates 26a to 26f of the same rectangular external shape elongated at rounded corners made of a metal or alloy that is a good heat conductor, each plate having, on its two lateral faces, reliefs made up of ribs and V-shaped grooves alternately and in succession, so as to draw rafters.
  • the six plates are placed next to each other so as to form five channels 27a to 27e, each of which is delimited between the two facing faces of two neighboring plates in the assembly.
  • Channels 27a to 27e are easily visible in Figures 2a and 2b, showing the heat exchanger exploded perspective plates, with plates 26a to 26e slightly apart each other.

  • This figure 2a represents the plate exchanger 14 in heating mode direct sanitary water circulating in secondary 16 (channels 27b and 27d) by the heating water coming from the tubing 4 and circulating in the primary 15 (channels 27a, 27c, 27e).
  • FIG 2b shows the plate heat exchanger 14 in holding mode in temperature and heating of domestic water in the tank 10 by circulation warming water from tubing 4 in primary 15 (channels 27a, 27c, 27e) in the absence of domestic water circulation in the secondary 16.
  • This heat exchange results from forced convection by circulation of heating water in the end channels 27a and 27e towards the side walls 26a and 26f, and a free convection, shown schematically by other arrows in Figure 2b, between these walls 26a and 26f and the water in the balloon 10, due to the direct contact of these external walls 26a and 26f with the water from the drawing circuit in the tank 10.

  • a wedge can be placed in the balloon 10 to support the end of the exchanger 14 ′ which is opposite to that enclosed in the flange 51.
  • the support piece 62 ' which cooperates in the same way as the support piece 62 with the half-flanges 52 and 53 and with the wall of the balloon 10 and therefore has substantially the same structure, suitable for this purpose, as the support piece 62, constitutes one bottoms of the balloon 10, for example its bottom bottom, closed sealed on the wall of the tank 10 thanks to the seal 64.
  • This arrangement allows a optimal functioning of the device, thanks to the exchanger 14 'at the bottom in the balloon 10.
  • the support piece 62 ' is different from the support piece 62 in what it presents arrangements allowing, in the balloon 10, the connection easy from tube 11 to draw hot sanitary water at the top in the tank 10, and, outside the tank 10, the connection sealed to the hot water outlet pipe 8 (see figure 1).
  • the support part 62 ' may include a fourth tubular end piece 71, in which the tube 11 is fitted with sealing, and connecting itself with sealing to the pipe from the hot water outlet 8 at its end external to the tank 10.
  • This example presents the advantages of a simplicity of realization of the tank 10 and a simplification of the assembly operations of the exchanger 14 ' in balloon 10 and checking this assembly.
