Description

The present invention relates to a heating installation for the

  preparation of heating water and sanitary water, in which a heat exchanger heated by a heat source, can be connected as desired, by a 3-way distributor, to heating radiators or

  a heat exchanger for domestic water which is

  tee in parallel with the radiators and whose circuit is

  condaire is connected to a domestic water tap.

  Such facilities are used for the preparation of

  heating water, to supply heating radiators

  at the same time for the preparation of domestic water using a heat exchanger for domestic water On known installations of this kind, an electrovalve supplying said heat exchanger releases the flow

  towards him This operation, however, involves the inconvenience

  deny that at the start of the hot water withdrawal, the water

  cooling must first be removed from the primary circuit of this heat exchanger before there can be

  heating flowing domestic water, which is

  obviously due to a delay in the preparation of 1 '

  hot water and, therefore, a waste of water.

  The present invention therefore aims to avoid these drawbacks by proposing a heating installation

  of the kind mentioned above ensuring that from the

  purpose of water withdrawal, this water is sufficiently hot

  of. According to the invention, this object is achieved by

  what is provided a main water heater tank

  2 - held at a relatively high temperature by the action

  a thermostat, and connected, via a

  3-way distributor arranged between the heat exchanger heated by the heat source and the 3-way distributor ensuring the supply of the heat exchanger for 1 '

  sanitary water, at the heat exchanger, and whose outlet

  tie is connected to the inlet of the heat exchanger for sanitary water, a regulating device controlled by the water intake tap being connected to the drive members,

  or in particular electro-magnetic organs, devices

3-way tributaries.

  In this way it is possible, from the start of the pre-

  water lift to channel water very quickly from the heating water tank to the heat exchanger to

  domestic water and heat it quickly.

  In a preferred embodiment of the invention, it can be provided that at the start of the water intake, the solenoid valve supplying the heating water tank

  is actuated to establish a connection between said reservoir

  see and the supply pipe coming from the heat exchanger and connect it to the heating circuit until a volume of water corresponding to that of the heat exchanger plus that of the pipes going to and from from the heating water tank, has arrived in said

  tank, then said solenoid valve cuts off

  re supply of said tank and at the same time the solenoid valve acting on the supply of the heat exchanger for sanitary water ensures the opening up to

at the end of the water intake.

  In this way, it is guaranteed that as soon as the hot water is taken from the respective tank, the water flows out.

  in the domestic water heat exchanger, which

  puts a rapid heating of this water.

  To make a particularly simple assembly of

  a water heating installation in accordance with the

  It is proposed, according to another characteristic,

-3-

  that of the invention, that the 3-way distributors are

  laid in series on a pipe connecting the heat exchanger

  their to the heating radiators, the third connection of the first 3-way distributor being connected in a known manner

  to the heat exchanger for domestic water, and the third

  the second connection of the second 3-way distributor arranged in

  be the first distributor and the heat exchanger,

  both connected to the inlet of the heating water tank, the outlet of which is connected to the inlet of the heat exchanger

for sanitary water.

  This mode also has the advantage that the installation

  tion can be carried out using components offered in

trade.

  In addition, it can be expected that the volume of the reservoir

  see heating water corresponds at least to the volume of the heat exchanger plus that of the inlet pipes

  and outlet connected to said tank.

  In this way, it is guaranteed that the heating water tank is replenished in sufficient quantity to expel from the heat exchanger and from the pipes supplying said tank and returning to the heat exchanger.

  heat the water possibly cooled during a moderate stop

heat source.

  According to another characteristic of the invention, provision may be made for the heating water tank to be provided with an effective insulating layer and, where appropriate,

  an additional heating device, the power of which

  fundamentally suffices only to compensate for the losses of

  heat of the water stored in the tank.

  In this way, it is guaranteed that the content of said tank is kept at a high temperature and that

  Consequently, at the start of the water withdrawal,

  hot water base for the primary circuit of the sample

heat sink for domestic water.

  According to another characteristic of the invention, it

  provision may be made for the regulating device to be a

  4 - rotary drawer stopper, connected to the heat exchanger, the heating radiators, the heat exchanger for domestic water and the inlet and outlet of the tank

  of heating water, and comprising a mobile section es-

substantially triangular.

  Such an embodiment of the regulating device per-

  puts to give it a very compact shape, as well as a

  simple assembly of the pipes, the drive of the said device

  positive that can be ensured by a single organ.

  Another object of the invention is the production of a rotary slide distributor suitable in particular for a water heating installation, and particularly for such an installation according to the invention, and comprising an essentially cylindrical body and a rotating mobile

in said body.

  In accordance with the invention, it is therefore proposed that

  this distributor body is provided with four connections

  spread evenly at a distance of 900 from each other around the perimeter, and from another connection provided between two

  of these connections, and that the mobile has a ramp

  roughly between the distributor fittings, op-

  placed diametrically one to the other, and another ramp delimiting a space which groups two distant connections of

  900 from each other, the mobile being provided with sealing faces

  sheath applied against the inner wall of the distributor body.

  This results in a very simple construction of the distri-

  rotary drawer stopper The fittings of said distributor can be connected, clockwise, to the heat exchanger, at the inlet of the tank

  heating water, to the heat exchanger for water

  unit, at the outlet of the heating water tank and to the heating radiators, which greatly facilitates the

mounting of the various pipes.

  Hereinafter, the invention is described with the figures of the drawing in support, which represent: -5-

  Fig 1, schematically a first example of realization

  sation of a water heating installation according to the invention;

  Fig 2, schematically a second example of re-

  installation of a conforming water heating installation

  ment to the invention; Fig 3 to 6, schematically a drawer distributor

  rotary according to the invention, in different positions.

  In the exemplary embodiment according to FIG. 1, the e-

  heat changer 1 is heated by a burner 2 and re-

  linked by a starting pipe 3 and a return pipe 4 to a set of heating radiators 5 In the pipe

  outlet 3 is provided a 3-way distributor 6 with an or-

  electromagnetic motor gane 7, which can communicate

  with a heating water tank 8 or release the hatch

  along the outlet pipe, if tank 8 is to

be cut.

  This heating water tank 8 is provided with an iso-

  thermal lation 19 preventing heat loss In addition, an additional heat source can be provided

  for tank 8, the power of which must however only

  sufficient to compensate for any loss of heat

  This keeps water accumulated in this re-

  serve at a high temperature.

  The heating water tank 8 is also connected to the inlet of the primary circuit of the heat exchanger

  9 for sanitary water, which is also connected to another

  be 3-way distributor 10 provided on the starting pipe

  3 and also actuated by an electromagnetic drive member

  tick 11 The distributor 10 clears or blocks the way to the heat exchanger 9, or communicates with the assembly

of radiators 5.

  The output of the primary circuit of the heat exchanger

  their 9 is connected to the return pipe 4.

  The secondary circuit of the heat exchanger 9 comprises a water intake tap 12 which communicates with 6 -

  a control device 13 which, at the time of opening-

  re from tap 12, emits a signal which triggers a function-

  drive units 7, 11 of the two distri-

3-way scorers 6, 10.

  When the water intake tap 12 is opened, the

  3-way diverter 6 is actuated to open the hose to the heating water tank 8 which is supplied up to

  that a volume equal to the volume Vl of the heat exchanger

  their 1, and to the volume V 2 of the pipes connecting the exchanger

  1 to the water tank 8, and to the volume V 3 of the

  picks connecting the reservoir 8 to the return connection of the

  heat changer 1, plus the volume of the primary circuit

  re from the heat exchanger 9, or channeled into the re

  heating water supply 8 This is water from

  tee at the flow temperature for all radiators

  heaters 5, because, when the water tap 12 is opened, the burner 5 is started in case it is not already activated by a call for heat

by said set of radiators.

  Then, the 3-way distributor 6 closes the pipe a-

  supplying the heating water tank 8 and releases the starting pipe 3, the distributor 10 releasing at the same time the supply of the heat exchanger 9 for domestic water and cutting the starting pipe 3, which ensures 1 ' power supply to the primary circuit of the heat exchanger

9 with hot water.

  When the water withdrawal is finished, the 3-way distributor is actuated to cut the power to the exchanger

  heat 9 and release the flow in the discharge pipe

  part The contents of the heating water tank are now

  held at a set temperature by thermostat 14, as long as there is no domestic water withdrawal

  Indeed, with the help of appropriate regulation, the distribution

  tor 6 supplies the reservoir 8, and the burner

  is switched on At the set temperature, the

  burner is stopped, and the distributor switches to release

7 -

  flow to the set of radiators 5 The heater

  the heating water tank can also be

  sourced by a preferably electric heat source,

independent of the burner 2.

  Heating water circulation is ensured by

  the pump 15 provided on the return pipe, between the connector

  cord of the heat exchanger for domestic water and

heat changer 1.

  In the embodiment according to fig 1, the

  regulating device 20 consists of the two devices

  3-way tributaries 6 and 10 installed between the pipes

  3 and a, the latter ending at the set of radia-

  teurs 5 The third fittings of these two distributors

  6, 10 are connected respectively by line b to the

  entry of the heating water tank 8, and through the

  te c at the outlet of said tank, this connection being further

  connected by line d to the inlet of the heat exchanger

their 9 for sanitary water.

  The example of embodiment according to fig 2 differs

  of the one according to fig 1 only because the provision

  regulator sitive 20 consists of a rotary slide valve 21 and its drive member 22 This valve

  with rotary slide 21 has five connections o are connected

  ticks, clockwise, the con-

  picks 3, b, d, c and a, linked as in the example of re-

  layout according to fig 1, to the various components of the installation, namely heat exchanger 1, tank

  heating water 8, heat exchanger 9 for hot water

  unit and set of radiators 5.

  The rotary slide valve 21 has a mo-

  bile 23 with an essentially triangular section A

  ramp 24 follows roughly the diagonal of the body 25 of the device

  tributor 21, a second ramp 26 delimiting a space which groups two fittings arranged at an angle of 900 1 '

one over the other.

  It is thus possible to supply, following the -8-

  fig 3, only the set of radiators 5 by the sample

  heat gor 1, other connections being prohibited,

  and the respective non-powered components.

  Fig 4 shows an intermediate position, the whole

  ble of radiators 5 no longer supplied and the tank

  heating water 8 not yet supplied.

  In FIG. 5, the distributor 21 occupies a position

  tion to circulate hot water from the sample

  heat sink 1 through the hot water tank

  fage 8 to the heat exchanger 9 for sanitary water

  re, i.e. a position where there is only prepa-

  sanitary water ration, this position corresponding to the

  start of hot water withdrawal.

  FIG. 6 shows the position of the distributor 21 which corresponds to the withdrawal of hot water after a start-up phase, the hot water flowing from the heat exchanger 1 directly to the heat exchanger 9 for domestic water, and hot water in remaining tank 8

in this last.
