Definitions

  • the present invention relates to the general field of domestic hot water (DHW) production.
  • the invention relates more particularly to a DHW production installation integrating energy recovery.
  • a preheating exchanger can, according to a first embodiment, be placed upstream of the cold water inlet in said DHW heater.
  • This preheating exchanger recovers calories with energy not recovered on other equipment such as, for example, a refrigeration unit, a solar boiler, or a steam exchanger.
  • This preheating exchanger transmits the calories normally lost to the cold water and thus preheats the water by several degrees. These recovered degrees represent an energy saving for the DHW heater, the setpoint of which is 60°C.
  • the preheating exchanger associated with energy recovery is arranged in the DHW loop in order to heat the latter from 55°C to 60°C.
  • This configuration is interesting because maintaining the temperature of the DHW loop represents on average 60 to 70% of the energy expenditure on the DHW. It is therefore interesting to heat the DHW loop using recovered energy.
  • ECS production installations such as that described in the European patent application are also known. EP 3 450 859 , these installations being efficient but not economical enough.
  • the aim of the present invention is therefore to overcome the drawbacks mentioned above by proposing an economical DHW production installation, of simple design and easy to implement, integrating DHW preheating and being capable of using a maximum quantity of recovered energy in order to reduce its energy consumption.
  • Said recycling module advantageously comprises a non-return valve arranged downstream of said recirculation pump and making it possible to prevent the return of a flow of water coming from the cold water inlet to said DHW loop.
  • the recirculation pump of the recycling module has a variable flow rate.
  • the first temperature probe is arranged downstream of said distribution point
  • the second temperature probe is arranged between the inlet of the secondary part of the energy recovery exchanger and the connection of the recycling module
  • the third temperature probe is arranged at the inlet of the primary part of the energy recovery exchanger.
  • the term “mounted directly in series” means that no other equipment is connected to the second branch 14B of said secondary circuit 11 arranged between the energy recovery exchanger 10 of the second primary circuit 6 and the DHW heating exchanger 5 of the first primary circuit 2.
  • DHW outlet refers to the area of the DHW loop 12 located downstream of the distribution point 15 and the term “DHW return” refers to the area of the DHW loop 12 located upstream of said distribution point 15.
  • the DHW production installation 1 may not include a storage tank 7, without departing from the scope of the present invention. Indeed, depending in particular on the size of the DHW production installation and/or the type of the energy recovery loop 8, a storage capacity will not necessarily be necessary.
  • the first, second and third branches 14A, 14B and 14C of the secondary circuit 11 are respectively arranged between the cold water inlet 13 and the inlet of the secondary part of the energy recovery exchanger 10, between the outlet of the secondary part of the energy recovery exchanger 10 and the inlet of the secondary part of the DHW heating exchanger 5, and between the outlet of the secondary part of the DHW heating exchanger 5 and the distribution point 15 on the DHW loop 12.
  • the first primary circuit 2 further comprises a three-way mixing valve 16 arranged between the outlet of the hot water production device 3 and the inlet of the primary part of the DHW heating exchanger 5, and managing the useful power of the DHW heating exchanger 5 by recirculating, via the branch 17, in greater or lesser proportion, a portion of the water coming from the outlet of the primary part of said DHW heating exchanger 5 on itself, so as to vary the temperature of the water at the inlet of said primary part of said DHW heating exchanger 5.
  • a three-way mixing valve 16 arranged between the outlet of the hot water production device 3 and the inlet of the primary part of the DHW heating exchanger 5, and managing the useful power of the DHW heating exchanger 5 by recirculating, via the branch 17, in greater or lesser proportion, a portion of the water coming from the outlet of the primary part of said DHW heating exchanger 5 on itself, so as to vary the temperature of the water at the inlet of said primary part of said DHW heating exchanger 5.
  • the energy recovery loop 8 makes it possible to recover calories to heat the DHW, wherever possible and in particular at the level of cold groups (air conditioning, refrigerator, etc.) or even solar panels.
  • the transfer pump 9 of the second primary circuit 6 is advantageously of variable flow rate to adapt the operation of the second primary circuit 6 to the DHW requirement.
  • the DHW production installation 1 also comprises a recycling module 18 connected between the DHW loop 12 and the first branch 14A of the secondary circuit 11, and comprising a recirculation pump 19 making it possible to take, downstream of said distribution point 15, a portion of the DHW from the DHW outlet of the DHW loop 12 to allow permanent circulation of DHW in the secondary part of the DHW heating exchanger 5 or the energy recovery exchanger 10, in order to prevent scaling of the DHW heating exchanger 5 and to combat heat losses on the DHW loop 12, but also to send water at 60°C into the energy recovery exchanger 10 to ensure the absence of legionella development therein.
  • the recycling module 18 comprises a non-return valve 20 arranged downstream of said recirculation pump 19 and making it possible to prevent the return of the flow coming from the cold water inlet 13 to said DHW loop 12.
  • the portion of the DHW taken from the DHW outlet can only necessarily circulate in the two energy recovery exchangers 10 and DHW heating exchangers 5, i.e. necessarily in the secondary portion of said energy recovery exchanger 10 and then in the secondary portion of the DHW heating exchanger 5.
  • the recycling module 18 of the present invention be able to circulate the part of the DHW from the DHW outlet only in the secondary part of said energy recovery exchanger 10, or only in the secondary part of the DHW heating exchanger 5, or even in the secondary part of the DHW heating exchanger 5 then in the secondary part of said energy recovery exchanger 10.
  • This configuration is economically interesting, because it allows, during the "DHW loop reheating" operating mode of the DHW production installation 1 described below, to use only the energy from the energy recovery loop 8 to reheat the DHW loop 12.
  • the DHW production installation 1 can operate according to different modes such as, for example, those described below with reference to: Figures 2 to 5 on which only the directions of circulation and the water temperatures are indicated, so as not to overload the said figures. It is understood that the said water temperatures are given for information purposes and are not exhaustive.
  • DHW production installation 1 operates to heat DHW loop 12.
  • this "DHW loop heating" operating mode there is no need to produce domestic hot water because no draw-off point (shower, washbasin, sink, etc.) is drawing.
  • a centralized domestic hot water production system must be able to maintain the temperature of the DHW in DHW loop 12 to ensure that hot water is quickly available at all points in said DHW loop 12, but also to imperatively maintain the DHW in DHW loop 12 at a temperature above 50°C for health reasons, in order to avoid the development of legionellosis.
  • the DHW return temperature is equal to a predetermined minimum temperature typically of the order of 55°C.
  • the purpose of this operating mode is therefore to heat the DHW in said DHW loop 12 from 55°C to 60°C.
  • the recirculation pump 19 of the recycling module 18 will take, downstream of said distribution point 15 (i.e. at the DHW outlet), a portion of the DHW at 60°C from the DHW loop 12 and circulate it in the energy recovery exchanger 10 of the second primary circuit 6.
  • the water mixture temperature measured by the second temperature sensor 22 is equal to the DHW outlet temperature, namely 60°C.
  • Said energy recovery exchanger 10 then makes it possible to heat the temperature of the water mixture by a few degrees, in the example shown from 60 to 63°C, and thus limit the energy expenditure provided by the DHW heating exchanger 5 of the first primary circuit 2.
  • transient operating mode is the most delicate operating mode, because it involves having to integrate time delays on the action of certain components of the DHW production installation 1 to guarantee its optimal operation.
  • the water entering the secondary part of the energy recovery exchanger 10 of the second primary circuit 6 is indeed a mixture of DHW at 60°C taken by the recirculation pump 19 of the recycling module 18 from the DHW outlet of the DHW loop 12 and cold water at 10°C coming from the cold water inlet 13 of the EV network, the temperature of said water mixture being, as a reminder, measured by the second temperature probe 22.
  • the water mixing temperature be as cold as possible.
  • the regulation of the DHW production installation 1 controls the stopping of the recirculation pump 19 of the recycling module 18, if the water mixture temperature measured by the second temperature probe 22 remains lower than or equal to a set temperature, in the example shown 50°C, for a predetermined period of time, of the order of one to three minutes, which means that there is a real draw of DHW at the level of the DHW loop 12.
  • the water mixture temperature is normally at 60°C, but in the presence of a real draw of DHW, this temperature of the water mixture begins to drop with the arrival of water at 10°C coming from the cold water inlet 13 of the EV network.
  • the regulation considers that there is a real draw of DHW and orders the stopping of the recirculation pump 19 of the recycling module 18.
  • the DHW production installation 1 then operates according to the "draw" operating mode and the energy recovery exchanger 10 of the second primary circuit 6 then only receives cold water at 10°C, which makes it possible to achieve a significant heat exchange and therefore to promote energy recovery.
  • the quantity of energy recovered depends on several parameters such as the DHW draw flow rate at the DHW loop 12, the temperature of the water entering the primary part of said energy recovery exchanger 10 measured by the third temperature probe 23 and the flow rate of the transfer pump 9 of the second primary circuit 6.
  • the DHW production installation 1 when the DHW draw at the DHW loop 12 stops, the DHW production installation 1 then operates according to the "draw stop" operating mode for which there is no longer any water supply at 10°C from the cold water inlet 13 of the EV network, the recirculation pump 19 of the recycling module 18 being stopped since the water mixture temperature measured by the second temperature sensor 22 is still less than or equal to 50°C.
  • the flow rate of water circulating in the DHW heating exchanger 5 of the first primary circuit 2 and the energy recovery exchanger 10 of the second primary circuit 6 is then zero and the DHW loop 12 is therefore not maintained at temperature.
  • the regulation controls the restarting of the recirculation pump 19 of the recycling module 18 to reheat the DHW loop 12, the DHW production installation 1 then operates according to the “DHW loop reheating” operating mode described above.
  • the flow rate of cold water entering the energy recovery exchanger 10 of the second primary circuit 6 is greater than the flow rate of the recirculation pump 19 of the recycling module 18.
  • the pressure of the water at 10°C coming from the cold water inlet 13 of the EV network is greater than the manometric height of said recirculation pump 19, which has the consequence of causing the latter to run at zero flow rate.
  • the regulation of the DHW production installation 1 then controls the stopping of the recirculation pump 19. recirculation 19 of the recycling module 1, since conventionally the pumps are not designed to operate at zero flow, and the DHW production installation 1 then operates according to the "drawing" operating mode described above.
  • the DHW production installation 1 allows, thanks to energy recovery and adapted regulation, both the reheating of the DHW loop 12 and the preheating of the water coming from the cold water inlet 13 of the EV network. It goes without saying that the quantity of energy recovered is variable and depends on the type of energy recovery loop 8.
  • the second primary circuit 6 be configured so that the hot water coming from the energy recovery loop 8 and entering the primary part of an energy recovery exchanger 10 is always at a temperature strictly higher than that of the water from the DHW loop 12 taken by the recycling module 18, i.e. that of the DHW outlet, to avoid any cooling of the DHW, in particular during the "DHW loop reheating" operating mode described above and to use only the energy from the energy recovery loop 8 to reheat the DHW loop 12.
  • this DHW production installation 1 can be adapted and used for other types of buildings such as, for example, hotels or high schools.
