Definitions

  • the invention relates to a method for the energy management of a heat network, into which heat energy is fed fluctuatingly and from which heat energy is withdrawn regardless of the amount of energy fed in, the heat energy being absorbed by a heat transfer medium on the generator side and released again on the consumer side by the heat transfer medium at the same or higher temperature level.
  • the invention also relates to a heating network.
  • the object of the invention can therefore be seen as providing a method and a corresponding device for energy management which, on the one hand, can be adapted to a wide variety of operating states and, on the other hand, combines different energy sources with high efficiency.
  • the method for energy management of a heat network into which heat energy is fed fluctuatingly and from which heat energy is withdrawn regardless of the amount of energy fed in, the heat energy being absorbed by a heat transfer medium on the generator side and released again on the consumer side by the heat transfer medium at an equal or higher temperature level, is characterized by the invention characterized in that the heat transfer medium circulates in a ring line between the energy producer side and the energy consumer side, connecting them with each other, that the temperature level to be achieved on the energy consumer side is modulated depending on the currently generated amount of energy and the respective energy requirement on the energy consumer side, taking into account stored thermal energy from a heat storage and/or by means of a heat pump connected to the heat storage and the ring line in a heat-transferring manner, it is provided that the heat transfer medium flowing in the ring line from the energy consumer side towards the energy producer side is supplied with heat to an
  • the combination of ring main, heat storage and heat pump enables the inclusion of different scenarios in energy management by interconnecting them.
  • the heat storage then serves as a buffer to either absorb heat from the heat network or to release heat to the heat network if a desired operating state cannot be achieved with the heat pump alone.
  • the heat storage is therefore always switched on, i.e. connected to the ring line in a heat-transferring manner, when the energy producer side, alone or in combination with the heat pump, provides less heat energy than is requested by the energy consumer side.
  • the heat transfer medium can be passed past the heat storage and the heat pump without passing through the condenser, the evaporator or the heat storage. Energy or heat transfer medium is therefore only supplied to the ring line via appropriate supply lines or heat transfer devices, whereby heat in the overall system can be controlled as effectively as possible.
  • This also creates the prerequisite that the ring line on the one hand and the heat storage and the heat pump on the other hand can be operated independently of one another and thereby form two separate heat transfer circuits.
  • the heat transfer medium in the ring line is also fluidically decoupled from a heat transfer medium on the energy producer side or a heat transfer medium on the energy consumer side or a heat transfer medium on the energy producer side and a heat transfer medium on the energy consumer side.
  • a further embodiment of the method provides that thermal energy stored in the ring line is transferred to the heat transfer medium flowing from the energy producer side towards the energy consumer side.
  • at least a partial flow can be conducted via a heat exchanger connected to the heat storage.
  • the partial streams are then mixed with one another in a quantitative ratio so that the heat transfer medium flowing from the partial streams again in the direction of the energy consumer side has the temperature level required by the energy consumer side.
  • the entire heat transfer medium flowing in the ring line can be routed via the heat exchanger and the amount of heat transferred from the heat storage to the heat exchanger is regulated in order to reach the requested temperature level on the energy consumer side.
  • a corresponding mode of operation can take place without involving the heat pump, that is to say without heat transfer to or from the heat pump, especially if only thermal energy is taken from the heat storage. This is the case, for example, when the heat storage has reached its capacity limit and heat has to be removed from the heating network.
  • heat transfer medium can circulate between a capacitor of the heat pump and the heat storage for the stored thermal energy.
  • the heat transfer medium heated in the condenser then heats up the heat storage, while at the same time heat energy is removed from it.
  • Such a mode of operation is particularly suitable if, on the one hand, the heat pump is running at full load in order to take electrical load from a connected power network, and on the other hand, thermal energy can and should be stored at the same time.
  • the thermal energy can be stored without removing thermal energy from the heat storage.
  • the heat pump then only removes as much heat energy from the ring line as it can process and can be absorbed by the heat transfer medium on the energy generator side. With this procedure, there is advantageously a low thermal energy requirement on the energy consumer side in order to be able to store as much thermal energy as possible.
  • the heat transfer medium flowing in the ring line from the energy consumer side towards the energy producer side can accordingly generate heat depending on the respective process or operating mode release an evaporator of the heat pump when the heat pump is switched on or pass through it without heat transfer.
  • the heat transfer medium circulating in the ring line can not only give off heat to the evaporator, but can also be fed to the condenser of the heat pump.
  • at least a partial flow of the heat transfer medium flowing from the energy producer side towards the energy consumer side in the ring line is conducted via the condenser of the heat pump.
  • the heat transfer medium which is heated and cooled at the same time as the heat pump, enables particularly efficient operation because the amount of heat absorbed on the energy generator side is increased.
  • a dynamic thermal balance can also be achieved between the energy producer side and the energy consumer side. This condition can therefore also be referred to as normal operation, particularly if the partial flow of the heat transfer medium is returned from the condenser directly into the ring line.
  • the heat transfer medium passed through the capacitor is fed from the ring line to the heat storage and heat transfer medium is fed into the ring line from the heat storage.
  • the heat transfer medium flowing in the ring line from the energy consumer side towards the energy producer side can consequently be supplied to the evaporator of the heat pump in a heat-emitting manner or can pass through it without heat transfer.
  • only a single heat carrier flows through the entire heating network the ring line with the energy producer side and the energy consumer side, the heat storage and the heat pump.
  • a refrigerant is circulated between an evaporator of the heat pump and a heat source that heats the refrigerant, the heated refrigerant absorbing heat from the heat transfer medium flowing in the ring line from the energy consumer side towards the energy producer side.
  • the heat transfer medium flowing in the ring line is then only indirectly connected to the evaporator, with the possibility of integrating at least one further low-temperature heat source, for example wastewater or air, into the heating network.
  • the ring line on the energy generator side is advantageously connected to a higher-temperature heat source, for example a heating system, and the heating network with the ring line is advantageously operated warm.
  • connected consumers can then be directly connected to the ring line, which means that the temperature of the heat transfer medium does not have to be increased before it can be used by a consumer.
  • a method operated with an intermediate refrigerant can also be integrated into a low-temperature heating network, with the heat source heating the refrigerant being the main heat source.
  • a heat source on the energy generator side for example the heating system, is then only switched on at particularly low temperatures, for example when a heat pump can no longer provide the required heat to the low-temperature heat source or this is no longer economical. If there is no refrigerant circulating between the evaporator and the ring line, the entire heating network is advantageously operated at low temperatures in order to minimize heat losses.
  • the desired temperature can then be achieved by supplying the heat transfer medium to at least one further heat pump, in particular a thermal energy output heat pump, with both centralized and decentralized procedures being possible.
  • the energy generator side is then advantageously connected to a low-temperature heat source and supplied with thermal energy from it.
  • the invention also relates to a heating network into which thermal energy is fed fluctuatingly and from which thermal energy is withdrawn independently of the amount of energy fed in, comprising at least one energy generator side, at least one energy consumer side connected in a heat-conducting manner to the energy generator side via a heat transfer medium flowing in the heating network, and at least one heat storage.
  • This heat network is characterized in that at least one ring line is formed between the energy producer side and the energy consumer side, that the heat storage is connected on the inlet side via a capacitor of a heat pump and on the heat release side is connected to the ring line via a heat exchanger, that a heat release line of the heat storage to the heat exchanger is connected to the heat storage on both sides, that the capacitor of the heat pump is connected to the heat storage on the inlet side via a storage extraction line of the heat storage, and that the ring line is connected to the evaporator of the heat pump in a heat-transferring manner with a section connecting the energy consumer side with the energy producer side.
  • This structure of the heat network ensures that heat energy stored via the heat exchanger connected to the heat storage can be delivered to the ring line in order to achieve a requested temperature level on the energy consumer side.
  • the heat storage in turn can be heated via the heat pump, with the temperature of the energy generator side Flowing heat transfer medium is lowered again and so more heat energy can advantageously be absorbed on the energy generator side by the heat transfer medium circulating in the ring line.
  • the heat storage thus serves as a buffer to either absorb heat from the heating network or to release heat to the heating network, so that different consumption or fluctuating energy production can be responded to.
  • the ring line advantageously forms a self-contained circuit for the circulating heat transfer medium, to which the heat pump and the heat accumulator and their components are each only connected via branches leading away from the ring line or supply lines leading to the ring line.
  • the heat transfer medium can thus be conducted past the heat storage and the heat pump in the ring pipeline.
  • a particularly effective heat transfer and mode of operation is also achieved in that the heat carrier flowing in the ring line is fluidically decoupled from a heat carrier on the energy producer side or a heat carrier on the energy consumer side or a heat carrier on the energy producer side and a heat carrier on the energy consumer side. Both the energy consumer side and the energy producer side are then connected to the ring line via heat exchangers, whereby a bypass can also be assigned to the heat exchangers on the energy consumer side and/or the energy producer side in order to ensure the most effective operation possible.
  • the storage extraction line branches into a capacitor feed line and a ring line feed line.
  • heat transfer medium from the heat storage can then also be introduced directly into the ring line.
  • the heat energy stored in the heat storage can be used, for example, as a replacement for one on the A failed heat source on the energy generator side can be used.
  • only one common extraction point needs to be provided on the heat storage, so that a structurally simple solution is found.
  • the ring line is connected to transfer heat both to the evaporator of the heat pump and to the capacitor of the heat pump.
  • the heat pump can also be used to transfer heat energy to the heat transfer medium flowing in the ring line.
  • a particularly favorable structure also results from the ring line being connected to the capacitor feed line via a capacitor branch line, with individual line sections being combined again.
  • the capacitor branch line advantageously branches off from the section of the ring line in which the heat transfer medium flows from the energy producer side towards the energy consumer side and to which the heat exchanger assigned to the heat storage is also connected or into which the ring line supply line flows.
  • a further reduction of lines or line sections with associated material savings can be achieved by branching a heat transfer line leading from the condenser into a storage supply line and a ring line return.
  • This branching enables the heat transfer medium supplied to the condenser from the ring line to be returned directly to the condenser via the ring line return line after its temperature has been increased.
  • Heat transfer medium removed from the ring line via the condenser can be fed to the heat storage. If heat transfer medium is simultaneously removed from the heat storage into the ring line, a corresponding volume compensation is then ensured.
  • the heat-transferring connection between the evaporator of the heat pump and the ring line is achieved in that the ring line with the section connecting the energy consumer side with the energy producer side is guided over the evaporator of the heat pump.
  • the heat energy is then transferred directly from the heat transfer medium in the ring line to the heat pump circuit of the heat pump.
  • the evaporator of the heat pump is connected to a refrigerant circuit in a heat-transferring manner, that the refrigerant circuit is guided in the flow direction of a refrigerant flowing in the refrigerant circuit first via a heat source and subsequently via a heat exchanger, and that the heat exchanger of the refrigerant circuit is heat-transferring with the the energy consumer side is connected to the section of the ring line connecting the energy producer side.
  • the refrigerant circuit requires a complex structure of the heating network, it creates the option of integrating another heat source into the heating network in addition to a heat source connected to the energy generator side.
  • the two heat sources can then generate heat energy at different temperature levels provide which can equally be used to operate the heating network, in particular to provide heat for it.
  • the heat source integrated via the refrigerant circuit has a lower temperature than the heat source integrated via the energy generator side.
  • the heat source integrated via the refrigerant circuit uses environmental heat such as geothermal energy, wastewater or comparable heat sources and the heat source integrated via the energy generator side is a heating system or the like.
  • the heat transfer medium flowing in the ring line then has a temperature level that can be used by households connected to the energy consumer side, for example, without further adjustment or conversion of the temperature level.
  • the heating network and especially its ring line must then be insulated in such a way that heat losses are minimized.
  • a low-temperature heat source for example geothermal energy or wastewater
  • the entire heating network can then be operated as a low-temperature heating network, with heat losses being reduced due to a smaller temperature difference to the surroundings.
  • the arrangement with a refrigerant circuit can also be combined with a low-temperature ring line, with the heat source on the refrigerant circuit then being the main heat source.
  • a heat source on the energy generator side is then only switched on when necessary, for example in a temperature range in which a heat pump can no longer work economically.
  • the ring line is guided past the evaporator of the heat pump assigned to the heat storage, on the heat exchanger interacting with the heat storage and / or on heat transfer devices on the energy generator side by means of a bypass.
  • a bypass facilitates the circulation of the heat transfer medium in the ring pipeline of the heating network, since fewer installations that hinder the flow have to be passed through and thus the heat transfer medium is conveyed more easily through the heating network.
  • the heat transfer medium is then passed through the heating network depending on the components required for a specific operating mode.
  • the energy consumer side of the ring line has at least one thermal energy output heat pump, which is connected to the ring line via its capacitor.
  • the thermal energy of the heating network is then brought to a usable temperature level for, for example, households or users connected to the heating network. This conversion can take place centrally or decentrally, with a corresponding number of heat energy output heat pumps being provided.

  • the heat energy release heat pump 5 and the ring line 1 are connected to one another in a heat-transferring manner via the capacitor 5 'of the heat energy release heat pump 5.
  • a heat storage device 7 and a heat pump 8 are also integrated into the heating network.
  • the heat storage 7 has a heat release line 9, the ends of which are connected to the heat storage 7 on both sides and are conducted via a heat exchanger 10.
