Definitions

  • thermodynamic water heaters that is to say water heaters coupled to a heat pump.
  • the present invention relates more particularly to an installation for the production of domestic hot water comprising a tank for storing and producing domestic hot water and a heat pump, the condenser of which enables heat exchange with the water contained in said tank. in order to heat it.
  • the invention also relates to a method for controlling this installation.
  • thermodynamic water heaters include a thermal storage tank coupled to a low power heat pump. Such an installation makes it possible to efficiently meet the demand for hot water in the homes.
  • the heat pump condenser is fixed with respect to the tank and enables heat to be supplied to most of the storage volume of this tank. This technique allows all of the water contained in the storage tank to be heated, but with a substantial heating time. In the majority of the cases observed, the result is that the entire volume of water contained in the tank is heated independently of the demand for domestic hot water in the home, and without the possibility of partial tank loading.
  • This conventional system is therefore not very flexible and can cause a drop in comfort for the user, due to a lack of hot water which can be quite long. Indeed, after a significant hot water withdrawal, the tank reaches a low temperature level and it is necessary to wait for the complete heating of the tank to find a high temperature level at the outlet of the tank.
  • the refrigerant circulating in the heat pump is composed of a mixture of two refrigerants having different boiling points.
  • the heat pump includes an accumulator which makes it possible to vary the ratio between the two refrigerants circulating in the circuit of the heat pump. This accumulator is placed downstream of the evaporator and upstream of the compressor.
  • this device does not make it possible to manage the additional volume of refrigerant in order to act on the total height of the refrigerant condensation zone in said condenser and its displacement over the height.
  • the object of the invention is to provide an installation for the production of domestic hot water which makes it possible to respond in an efficient, continuous and inexpensive manner to the variation in the hot water requirements of the users of a thermodynamic water heater.

  • the installation comprises a central control unit for said device for introducing and extracting an additional volume of refrigerant, this unit being provided with a control interface, said condenser is a heat exchanger. heat disposed around said balloon or inside said balloon over at least part of the height thereof, said central control unit acting on said device either to introduce an additional volume of refrigerant into the refrigerant circuit of the heat pump and cause the reduction of the total height of the refrigerant condensation zone in said condenser and its displacement upwards from said condenser, or to extract a volume of refrigerant from the refrigerant circuit of the heat pump and cause the increase in the total height of the condensing zone of the refrigerant in said condenser and its downward displacement d udit condenser.
  • the invention also relates to a method for controlling the aforementioned installation.
  • the invention also relates to a computer program comprising instructions for implementing the aforementioned control method when it is executed on the central unit.
  • the installation 1 comprises a tank 2 for storing and producing domestic hot water, coupled to a heat pump 3.
  • the balloon 2 extends vertically. It is for example conventionally a cylindrical balloon.
  • the heat pump 3 comprises a refrigerant circuit 30, inside which circulates a refrigerant, preferably a single fluid.
  • a compressor 31 On this circuit 30 are connected in series: a compressor 31, a heat exchanger 32 (here a condenser) coupled to the tank 2, an expansion valve 33 and another heat exchanger 34, which here acts as an evaporator.
  • a heat exchanger 32 here a condenser
  • the evaporator 34 is for example an air / refrigerant exchanger, which recovers the heat contained in the air, for example the air outside the building in which the installation 1 according to the invention is located.
  • the condenser 32 is a heat exchanger arranged vertically inside the tank 2 or preferably around the latter (see figures 1 and 2 ) over at least part of the height of the latter.
  • this condenser 32 is a tube 320, wound in a spiral over at least part of the height of the balloon 2. More preferably, this tube 320 extends over at least two-thirds of the height of the balloon 2, from the bottom of it. It can also extend over the entire height of the balloon 2, as shown in the figures 1 and 2 .
  • the installation 1 also comprises a device 4 for introducing and extracting an additional volume of refrigerant into and out of the refrigerant circuit 30 of the heat pump.
  • this introduction / extraction device 4 is connected to the portion 301 of the circuit 30 which extends between the downstream of the compressor 31 and the upstream of the condenser 32, with respect to the direction of circulation of the fluid in the circuit 30.
  • This direction of circulation is symbolized by the arrows on the figures 1 and 2 .
  • This choice of positioning is motivated by the fact that it is at the outlet of the compressor 31 that the pressure is highest in the refrigerant circuit 30 and by the fact that the greater the pressure difference between the point of the circuit 30 from where the refrigerant is extracted and the bottle and more the filling thereof is fast and efficient.
  • the device 4 comprises a storage bottle 40, connected to the portion 301 of the circuit 30 by a so-called “extraction” pipe 41, which opens into the upper part of the bottle 40.
  • the part of this bottle 40 is also also connected to the portion 301 of the circuit 30, by a so-called “introduction” pipe 42, equipped with a valve 43, for example a solenoid valve.

  • portion 301 of circuit 30 has a reduction in section 300 at which the pipe 42 emerges.
  • the bottle 40 To charge the bottle 40 with refrigerant, it is maintained at a temperature lower than the condensing temperature of the refrigerant circulating in the circuit 30. This has the effect of sucking a part of the refrigerant circulating in the circuit 30 to the end. inside the bottle 40. A fraction of the refrigerant sucked in condenses to obtain refrigerant in the lower position of the cylinder 40, and the rest of the refrigerant is in the form of a gas in the upper part of the cylinder 40. A a certain volume of refrigerant is thus withdrawn from circuit 30.

  • Installation 1 can operate in “normal” mode, in “stimulated” (or “boost” ) mode, or in “learning” mode.
  • the figure 1 represents the normal operating mode of the installation.
  • the refrigerant leaves the compressor 31 at high temperature and in the vapor state and then enters the condenser 32 where it releases the accumulated heat and thus performs a heat exchange with the sanitary water contained in the tank 2.
  • the cooled refrigerant At the outlet of the condenser 32, here at the bottom of the figure 1 , the cooled refrigerant, in the liquid state and under high pressure, enters the expansion valve 33 where its pressure decreases.
  • the low pressure liquid refrigerant then enters the evaporator 34 where it accumulates heat from an external source, for example here air, which has the effect of vaporizing the refrigerant which returns to the compressor 31 .
