Definitions

  • the present invention relates to a compact heat transfer module.
  • This installation 10 comprises a primary generator 12, for example a fossil energy generator or a condenser of a heat pump that heats water circulating in a primary loop 14 (or primary circuit), a pump 16 ensuring the circulation heated water in the primary loop 14.
  • the installation 10 further comprises a secondary hot water generator 18, for example a condenser of a heat pump or a fossil energy generator, which provides heating of the hot water.
  • water in a secondary loop 20 (or secondary circuit) a second pump 22 ensuring the circulation of water in the secondary loop 20.
  • the secondary loop 20 includes the heating loop 24 itself, that is to say heat emitters in the rooms to be heated.
  • decoupling bottle 26 (or pressure-reducing bottle or hydraulic separator).
  • the main function of this decoupling bottle 26 is to make the primary loops 14 and secondary 20 hydraulically independent, so that the flow rates of the primary and secondary loops depend exclusively on the characteristics of the pumps included therein.
  • This decoupling bottle 26 thus transfers heat from the primary loop 14 to the secondary loop 20, while allowing to have different rates in these loops.
  • the object of the invention is to provide a heat transfer module to avoid at least partly the aforementioned drawbacks.
  • the invention also relates to a fluid thermal control installation comprising a heat transfer module as described above in all its combinations and a secondary loop including at least one fluid radiator or a transmitter adapted to cool water cooling, and / or at least one valve and / or at least one heat exchanger, the secondary loop being connected to the first fluid outlet and at the first fluid inlet of the decoupling bottle.
  • the secondary loop also comprises a fluid circulation pump.
  • the secondary loop comprises a heat generator for heating at least a portion of the water flowing in the secondary loop.
  • the heating installation further comprises a heat pump whose condenser is adapted to heat the water in the heat exchange device.
  • the heating installation further comprises a heat pump whose evaporator is adapted to cool the water in the heat exchange device.
  • the Figures 2a, 2b represent a heat transfer module 30 for a fluid heating installation, in this case a hot water heating installation.
  • This heat transfer module 30 firstly comprises a heat exchange device 32 for heating water flowing in the heat exchange device 32 from a cold water inlet 34 to a hot water outlet 36
  • the heat exchange device 32 is in this case a condenser of a refrigerant circulation circuit of a heat pump device.
  • the circuit is partially represented on the figure 2b which notably shows the arrival of hot refrigerant at an inlet 40 of the condenser and the cold refrigerant outlet at an outlet 42 of the condenser.
  • the heat transfer module 30 furthermore comprises a decoupling bottle 44 of generally cylindrical outer shape.
  • the decoupling bottle 44 is fixed on the heat exchange device 32. In this case, the decoupling bottle 44 is fixed directly on the heat exchange device 32.
  • the decoupling bottle 44 comprises an inlet 46 and a hot water outlet 48 and an inlet 50 and an outlet 52 of cold water.
  • the hot water inlet 46 of the decoupling bottle 44 is connected directly to the hot water outlet 36 of the heat exchange device 32 and the cold water outlet 52 of the decoupling bottle 44 is directly connected to the cold water inlet 34 of the heat exchange device 32.
  • connection directly is meant that the elements in question are connected without implementation of piping. This can be achieved in particular by choosing a distance between the hot water inlet 46 and the cold water outlet 52 of the decoupling bottle 44 equal to the distance between the hot water outlet 36 and the inlet of cold water 34 of the heat exchange device 32.
  • these inputs and output can be arranged vis-à-vis, the fixing of the decoupling bottle 44 on the heat exchange device 32 ensuring the communication fluid of these inputs and outputs, with a satisfactory seal.
  • it is possible to fix the inputs and outputs by means of complementary screwed ends. To ensure a satisfactory seal, seals can obviously be implemented at these inputs and outputs.
  • the decoupling bottle 44 has dimensions that make it possible to respect the sizing of a known decoupling bottle, in order to allow a water flow to be decoupled hydraulically between the cold water outlet 52 and the hot water inlet. of the decoupling bottle 44, on the one hand, and a flow of water between the hot water outlet 48 and the cold water inlet 50 of the decoupling bottle 44, on the other hand.
  • decoupling bottle is indeed subject to rules well known to those skilled in the art, to ensure its decoupling function flow (see in particular the so-called 3d method, or the book Hydraulic Bottles and Bypasses, R. Cyssau, MH Chandellier and C. Marziou - ISBN: 2-236-00111-8 ).
  • the decoupling bottle 44 is preferably made of thermoplastic material, for greater ease of production. This bottle of decoupling 44 may in particular be performed in two or three separate pieces assembled, plus possibly two covers.
  • the decoupling bottle 44 is preferably made of a material having a low thermal conduction, to prevent heat loss at the decoupling bottle.
  • the material forming the decoupling bottle may have a thermal conduction of less than 1 W.m-1.K-1
  • a pump 54 circulation is further provided, fixed directly on the decoupling bottle 44.
  • the pump 54 allows in particular the flow of water from the cold water inlet 50 to the hot water outlet 48, via the heat exchange device 32.
  • the suction of the pump 54 in the decoupling bottle 44 is directly integrated on the bottle, in a free volume, near the cold water inlet 50 of the decoupling bottle 44.
  • the discharge outlet of the pump 54 is in direct communication, and isolated from the free volume, with the cold water outlet 52 of the decoupling bottle 44 to the heat exchanger 32, via a closed conduit 53 which passes through the decoupling bottle 44.
  • the decoupling bottle 44 can have, inside, a duct 56 here cylindrical and right connecting the neighborhood from the hot water inlet 46, in the decoupling bottle 44, to the hot water outlet 48 of the decoupling bottle 44.
  • the decoupling bottle 44 may also comprise a duct, shorter than the straight duct 56 and bent with an angle greater than 45 °. This bent duct is located at the cold water inlet 50, which it puts in fluid communication with the free volume inside the decoupling bottle 44, in the vicinity of the suction inlet 57 of the pump 54.
  • This angled duct firstly makes it possible to reduce the speed of the flow of water in the vicinity of the suction inlet 57 with respect to the speed at the level of the cold water inlet 50.
  • This duct is angled thus prevents the incoming water flow propagates upwards, in the figures, of the decoupling bottle, where it could cool the flow of hot water.
  • This angled duct and, more generally, the configuration described above of the decoupling bottle thus make it possible to comply with the rules for dimensioning the decoupling bottles (to have the decoupling effect of the water flows) while having the water inlet and outlet of the decoupling bottle 44 disposed on the same face of the decoupling bottle 44. This facilitates the connection of the transfer module in a fluid thermal control installation and limits the bulk.
  • the duct 56 can be fixed on the wall of the decoupling bottle 44.
  • the transfer module 30, in particular the decoupling bottle 44 can also be adapted to the implementation of ancillary functions.
  • the transfer module, in particular the decoupling bottle may have at least one of a flow meter, a purge device, a waste trap device and sludge.
  • the transfer module 30 may in particular be implemented in a water heating installation 58 as illustrated in FIG. figure 3 .
  • the primary loop 60 of this water heater 58 is formed by the transfer module 30.
  • the heat exchange device 32 may be a heat exchanger (for example a plate heat exchanger) for heating the water.
  • this heat exchanger can be a condenser of a water heating circuit by means of a heat pump 62, partially represented on the figure 3 , a refrigerant in the gas-liquid exchange phase circulating in the condenser.
  • the secondary loop 64 of the water heating system 58 is connected to the hot water outlet 48 of the heat transfer module 30 and to the cold water inlet 50 of this same heat transfer module 30. 66 allows the circulation of water in the secondary loop 64.
  • the secondary loop 64 includes in particular a second heat exchanger 68, for heating the water circulating in the secondary loop and a heat emitter 70 (or fluid radiator, including water radiator).
  • the secondary loop 64 further comprises a third heat exchanger 72 - in this case a plate exchanger - which makes it possible to heat water of an independent circuit by means of the water circulating in the secondary loop 64. it is thus possible to obtain domestic hot water which can in particular be delivered at points of draw (faucets) 74.
  • the cold water inlet 50 of the decoupling bottle 44 of the heat transfer module can be made in the form of a "T" connection, this making it possible to connect two return ducts.
  • a complementary heating source in particular of the electric type, can be arranged in the heat exchange device or in the decoupling bottle.
  • the heat transfer module 30 can be implemented in a fluid air-conditioning installation.
  • the heat exchanger present in the heat exchange device may in particular be an evaporator of a heat pump adapted to cool water or any other refrigerant present in the heat exchange device.
  • the secondary loop then has at least one transmitter suitable for cooling by cold water, such as a fan coil or a cooling floor heating, in particular.
