Definitions

  • the present invention relates to a system for supplying a plurality of consumer units arranged in a building with exergy for heating and/or cooling, the system comprising the plurality of consumer units, wherein each consumer unit has a first high-temperature circuit and a low-temperature circuit with a heat transfer medium, which low-temperature circuit is designed to extract energy in the form of low-temperature heat from a low-temperature energy source.
  • anergy is the part of the energy that cannot be used in the system under consideration.
  • Exergy is the part of the energy that can be used in the system under consideration.
  • Electric current for example, consists of 100% exergy in every system, while air at ambient temperature in the system's surroundings consists of 100% anergy, but cooler or warmer air in the system's surroundings contains exergy.
  • anergy is not used, but instead low-temperature heat, on the one hand in order to remain independent of the reference system, but on the other hand also to make it clear that the term also includes low-temperature sources that are low exergetic in relation to their environment.
  • the low-temperature energy source can therefore typically be ambient air or geothermal energy. It is also conceivable that it is waste heat, for example from an industrial process.
  • the heat losses are directly proportional to the temperature difference between the heat transfer medium of the high-temperature supply circuit and its surroundings. The higher the temperature difference between the heat transfer medium of the high-temperature supply circuit and its surroundings, the greater the heat losses. In order to minimize these losses, the high-temperature supply circuit must therefore be insulated accordingly.
  • Another aim of the present invention is to create an exergy-efficient system that makes use of the available low-temperature heat even in summer.
  • each consumer unit within the building is assigned a heat pump which is designed to to supply the first high-temperature circuit of each consumer unit with exergy in the form of heat and wherein the low-temperature circuit is arranged to supply the primary side of each heat pump with low-temperature heat.
  • the consumer units can be individual residential units in a building, whereby a residential unit can extend over one or more floors of the building.
  • a residential unit consists of at least one high-temperature circuit or an interconnection of high-temperature circuits, which is supplied with exergy in the form of heat at least at one point of this interconnection.
  • a consumer unit may, for example, be one or more floors of a building, with each floor having one or more high-temperature circuits and, in this case, several residential units may be arranged on one floor.
  • each consumer unit comprises at least one high-temperature circuit, which, for example, forms a heating circuit for the consumer unit.
  • each consumer unit can also have a second high-temperature circuit, which can be a circuit for heating domestic water (domestic water or drinking water circuit).
  • each heat pump is positioned as close as possible to the respective consumer unit.
  • a consumer unit is a residential unit
  • the associated heat pump is located within the residential unit.
  • the heat pump assigned to a consumer unit is located at least on the same floor of a building as the consumer unit.
  • a building may also contain consumer units that are not part of the system according to the invention. It is entirely conceivable that a building may have ten consumer units, eight of which are part of the system according to the invention and two consumer units are supplied with exergy for heating and/or cooling by other means.
  • the low-temperature circuit can be extended close to the consumer units. Unlike in the prior art, the provision of exergy in the form of heat or cold is not centralized but decentralized. According to the invention, the low-temperature heat can thus be transported within the building close to or into the consumer units and only then used decentrally to operate the heat pumps.
  • thermoelectric heat pumps can be used as heat pumps.
  • the term heat pump is not to be understood exclusively with regard to these classic thermoelectric heat pumps.
  • thermoacoustic heat pumps are used without deviating from the inventive concept.
  • the heat pump can also be a reversible heat pump, i.e. a heat pump that can be operated in two directions and can therefore be used either for heating or cooling.
  • the transport of low-temperature heat from the low-temperature source to the decentralized heat pumps takes place by means of a low-temperature circuit in which a heat transfer medium (brine) circulates.
  • a heat transfer medium (brine) circulates.
  • the low-temperature circuit comprises a pumping station with a pump that circulates the heat transfer medium in the low-temperature circuit, as well as two sections, one section between the pumping station and the low-temperature source and the other section between the pumping station and the heat pumps distributed throughout the building.
  • the low-temperature circuit consists of a main flow line, via which the heat transfer medium of the low-temperature circuit is transported from the low-temperature energy source to the decentralized consumer units or to the decentralized heat pumps, as well as a main return line, via which the heat transfer medium can be transported back to the low-temperature energy source.
  • the pump is arranged in the main flow line of the low-temperature circuit.
  • the distribution of the heat transfer medium of the low-temperature circuit to the heat pumps or consumer units distributed throughout the building takes place from the main flow line of the low-temperature circuit via a first group of branch lines.
  • the return transport from the heat pumps or consumer units distributed throughout the building to the main return line of the low-temperature circuit can take place via a second group of branch lines.
  • branch lines By providing branch lines, there is flexibility in the arrangement of the decentralized heat pumps and local conditions can be better taken into account.
  • the branch lines can have a smaller diameter than the main flow line and the main return line and enable the heat transfer medium of the low-temperature circuit to be distributed more finely in the building.
  • the first group of branch lines and/or the second group of branch lines are arranged within the building.
  • the main flow line and the main return line of the low-temperature circuit can also run outside the building and be intended to supply other buildings, while the branch lines to the consumer units inside the building.
  • running inside the building is to be understood as an arrangement that does not exclude the last section of the branch lines, which only serves to connect to the main supply line or the main return line, from running outside the building.
  • branch lines are not mandatory. It is entirely conceivable that the decentralized heat pumps are supplied with low-temperature heat directly via the main flow line of the low-temperature circuit.

  • the first heat exchanger can either be supplied with the heat transfer medium of the low-temperature circuit or the heat transfer medium of the low-temperature circuit can be transported directly to the primary side of the heat pump, bypassing the first heat exchanger.
  • a consumer unit can also have a second heat exchanger, which can be fed on one side by the first high-temperature circuit and on the other side by the second high-temperature circuit, so that by means of the first and second high-temperature circuits a consumer unit can be supplied on the one hand with Heat for heating purposes but also heat for domestic water treatment can be supplied.
