Definitions

  • the invention relates to the technical field of heat exchange, and heat networks.
  • the subject of the invention is a method for pooling thermal energy (heat) at the scale of the territory in which a heat exchange loop is implemented which links at least one thermal energy consumer site and at least one site producing thermal energy.
  • the invention also relates to a heat pooling system for implementing said method.
  • Air coolers that are exchangers between process fluids and air, intended to dissipate heat in the air, these devices are usually equipped with electric fans to force air circulation; - And / or cooling towers, kind of natural draft chimneys, in which water is sprayed to help cooling. Here again the heat goes into the atmosphere.
  • cooling water in general the cold water being obtained either by heat exchange in a heat exchanger with sea water, river ... or by cold groups .
  • the heat is lost in the environment.
  • Thermal integrations between factories and / or residential or office premises are rare, because when a thermal integration is retained, the two parts become dependent on the operation of the other.
  • Such an example of energy integration is for example described for the heating of agricultural greenhouses in http://www.innovagro.net/pdf/agro- industries.pdf.
  • the invention relates to a heat-sharing method at the scale of the territory in which a heat exchange loop is implemented linking at least one thermal energy consumer site and at least one thermal energy generating site, said loop comprising a heat transfer fluid whose flow rate is adjusted so that at any point of the loop the temperature differences are less than 20 ° C, or the said site (s) consumer (s) taking in a point of the loop the energy required by heat exchange and the site or these site (s) producer (s) rejecting by heat exchange the energy produced in excess.
  • the temperature of the loop is kept constant by means of a booster heater.
  • thermobattery-type heat buffer storage is used to store excess thermal energy within the loop.
  • a Rankin Organic Cycle can be introduced into the loop to valorise excess thermal energy in electrical form.
  • the heat transfer fluid is chosen from water, aqueous mixtures, alcohols, hydrocarbons or ionic liquids.
  • the heat transfer fluid may comprise particles of phase change material.
  • the invention also relates to a territory-wide heat pooling system comprising:
  • a heat exchange loop which interconnects said thermal energy consuming sites and said thermal energy generating sites, and which comprises heat exchangers and a heat transfer fluid whose flow rate is adjusted by means of a pump.
  • the loop may comprise a booster heater.
  • Figure 1 illustrates a known system of the prior art consisting of an industrial boiler C to provide a hot fluid (1) generally water at a temperature around 100 ° C and to recovering the cooled fluid (2) back by the user, for example buildings placed in parallel B1, B2, ... Bn.
  • Figures 2 to 5 illustrate the invention without limitation.
  • Figure 2 shows the system according to the invention for the implementation of a heat exchange loop between transmitters (eg factories) and energy consumers (eg buildings).

  • Figure 5 illustrates the embodiment of the invention, wherein the heat transfer fluid (s) of the chemical loop comprises or comprise a phase change material in the form of capsules.
  • the system according to the invention (FIG. 2) consists in setting up between a set of consumers and energy emitters a common loop of a coolant.
  • energy emitters By means of heat exchangers located on the pipe of the loop, according to their needs, consumers take the energy they need by heat exchange and the emitters reject by heat exchange the energy they produce in excess.
  • a coolant circulates in the loop connecting energy consumers (buildings B1, B2, B3, Bn) and energy emitters (factories U1, U2).
  • the flow rate of the coolant is chosen so that at any point of the loop the temperature differences are small, preferably between 5 and 20 ° C (for example, the maximum temperature difference may be 20 ° C that is, a higher temperature of 80 ° C and a lower temperature of 60 ° C).
  • the coolant is any fluid for exchanging heat in the various heat exchange equipment and is preferably selected from fluids in the liquid state at pressures between 1 and 20 bar relative, so that the price of pipe of the loop does not become too high.
  • An example of a coolant can be cited water or aqueous mixtures or alcohols or hydrocarbons or ionic liquids.
  • Examples of consumers include domestic or industrial buildings to be heated, or factories that use industrial processes that require heat, such as for drying operations, for example in the food industry.
  • factories to dissipate heat that was lost to the atmosphere according to the prior art.
  • the temperature of the loop is advantageously maintained, for example if the energy balance of the contributors to the loop (here the factories Ul and U2) is deficient, using a booster heater C whose size is strongly reduced compared to the industrial boiler of the prior art which was the only source of heat.
  • the overall energy consumption according to the invention is greatly reduced, since the heat is pooled within the loop, and the auxiliary boiler is dimensioned in order to smooth temperature differences within the loop. of the loop.
  • the system (FIG. 3) can be equipped with one or more Q pooled heat buffer storages, called “thermobatteries” by the companies that manufacture them (ex: German company H. M. Schukôrper).
  • the storage system uses, for example, sodium acetate.
  • the heat storage allows to smooth the temperature of the loop over time (for example days / nights or summer / winter) or also to ensure the heating of buildings when a heat supplier plant is in maintenance operation.
  • the system can also (FIG. 4) be equipped with an organic Rankin cycle (COR) which makes it possible to recover the excess thermal energy (instead of sending it to a cooler such as an air cooler) in electrical energy when needed, such as in summer, where the heating requirements are reduced.
  • COR organic Rankin cycle
  • This electrical energy can advantageously be used for the operation of air conditioners.
  • one of the users may need a thermal level higher than the temperature level of the hot loop (for example, a thermal level of 120 ° C. is required for industrial food cooking with a loop maintained at a temperature of temperature close to 70 ° C): in this case, the user can install a booster heat pump that can raise the temperature with an additional electricity consumption.
  • a thermal level higher than the temperature level of the hot loop for example, a thermal level of 120 ° C. is required for industrial food cooking with a loop maintained at a temperature of temperature close to 70 ° C
