Definitions

  • the invention relates to an installation for producing hot water.
  • a heating body is used, the nominal power of which corresponds substantially to the average power per unit of time (for example 24 hours) usually required at the installation, and this generator is enclosed in a storage tank.
  • large capacity to cope with any significant instantaneous demand, essentially by playing with the stratification in this balloon of the hot layers which are placed above and the cold layers which are placed below.
  • the disadvantage of this type of installation is that it lacks flexibility, particularly in terms of the production of the heating generator enclosed inside a large capacity storage tank, and also in terms of the layout. in premises of such an installation.
  • Document GB-A-670 644 proposes a hot water production installation of this second type comprising two tanks; a first tank of reduced volume for bringing the water to temperature by means of a heating body situated under its base, and a second tank, of greater volume than that of the first, intended for the storage of water which was heated in the first tank, this water being drawn from this second tank in the event of significant demand. Under such heavy withdrawal conditions, recirculation of water between the tanks is provided.
  • the object of the invention is to solve these difficulties.
  • the first tank communicates with the second tank by an overflow of overflow.
  • the first tank With such a design of the installation, it is possible to build the first tank with its integrated heating body in the best operating, efficiency and installation conditions of this unit.
  • the provision of the second tank the volume of which is practically independent of that of the first, enables storage of the strictly adapted volume required.
  • the design and construction of this second tank are particularly simple, since it is essentially a storage tank.
  • the first tank communicates with the second by an overflow of overflow, it is ensured that the heating body always remains submerged by the first tank, which constitutes an essential criterion for the operational safety of this heating body.
  • the recirculation of low-flow water provided between the second tank and the first makes it possible to avoid any drop in temperature of the water stored in the second tank, if the storage period without sampling is particularly long.
  • the variable level of hot water stored in the second tank makes it possible to meet any instantaneous demand, even of high flow rate, the storage tank being refilled during periods of low withdrawal or of non-use of the installation.
  • a first tank 1 of reduced volume in which is immersed the heating body 2 of the installation constituted for example by a heat generator operating with a mixture of combustible gas and air supplied in 3 in the installation.
  • the combustion products leave the heating body 2 as indicated in 4.
  • these combustion products or "fumes" are brought into the tank 1 on the side of this tank or cold water entering the installation is introduced as indicated by the arrow 5 through the pipe 6.
  • the tank 1 may for example have a number of walls such as the wall marked 7 in the drawing ensuring a certain circulation of the water to be heated against the current with the combustion gases.
  • the hot water outlet advantageously takes place on the opposite side as indicated by the pipe 8 forming too full, which pours into the storage tank 9.
  • This tank 9 essentially forms a buffer tank and the level of hot water in this tank varies according to demand, for example between a minimum height h m and a maximum height hM.
  • the hot water withdrawal for the needs of the installation is done by a pipe 10.
  • recirculation can be provided at a reduced flow of water between the tank 9 and the tank 1 by means of a pipe. 11 and a recirculation pump 12.
  • the recirculation pump 12 can optionally be controlled by thermostatic means turning it on when the temperature of the water stored in the tank 9 drops below a predetermined value.
  • the installation obviously includes conventional regulating members ensuring the stopping of the cold water inlet at 5 if the tank 9 is full and possibly stopping the drawing of hot water in the tank 9 if the level in this tank reaches the predetermined minimum level hm.
  • the heating tank 1 may be arranged at least partially in the storage tank 9.
  • volume of the storage tank will be optimized according to the peak flow to be satisfied, its duration and its frequency.
