Abstract: The present invention relates to a method for controlling one or more heat pumps (110) connected to a distribution grid (10) for fluid-based distribution of heating and cooling in order to, at least partly, compensate for a cold outtake from the distribution grid (10) by a first cooling machine (120) connected to the distribution grid (10). Alternatively, or in combination, one or more cooling machines (120) connected to the distribution grid (10) may be controlled in order to, at least partly, compensate for a heat outtake from the distribution grid (10) by a first heat pump (120) connected to the distribution grid (10). The controlling is made a control server (200) monitoring outtake of heat and/or cold from the distribution grid (10) by the heat pumps (110) and cooling machines (120) connected to the distribution grid (10). The control server (120) generates and sends out control messages to the heat pumps and/or cooling machines.

Abstract: The present invention relates to a method for controlling setting of reversible heat pump assemblies (100) of a district thermal energy distribution system (1) in either a heating mode or a cooling mode. The method comprises: determining, at a control server, a first set of the reversible heat pump assemblies (100) to be set in the heating mode during a future time period; determining, at the control server, a second set of the reversible heat pump assemblies (100) to be set in the cooling mode during the future time period, wherein the second set of the reversible heat pump assemblies (100) is separate from the first set of the reversible heat pump assemblies (100); sending, from the control server (200) to the reversible heat pump assemblies (100) of the first set of the reversible heat pump assemblies (100), a respective control message to set the respective reversible heat pump assembly (100) in the heating mode for the future time period; sending, from the control server (200) to the reversible heat pump assemblies (100) of the second set of the reversible heat pump assemblies (100), a respective control message to set the respective reversible heat pump assembly (100) in the cooling mode for the future time period; and setting the respective reversible heat pump assembly (100) in either the heating mode or the cooling mode for the future time period.

Abstract: A stand-alone long-distance closed-loop heat energy capture, conveyance, and delivery system, comprises three closed-loop modules in serial communication. The first module is in communication with a first closed-loop piping infrastructure interconnected with a source of heat energy, and has a LBP liquid circulating therein whereby the LBP liquid is converted into its gas phase when flowing through the source of heat energy thereby capturing a portion of heat energy therefrom, and is converted into its liquid phase when flowing through a first heat exchanger that transfers the captured-heat energy to a second closed-loop piping infrastructure wherein also is circulating a LBP liquid. The second closed-loop module may extend for long distances. The captured-heat energy in the second module is transferred to a third closed-loop piping infrastructure wherein is also circulating a LBP liquid. The captured-heat energy is transferred from the third module to a delivery site.

Abstract: A local energy distributing system includes a local feed conduit; a local return conduit; a central heat exchanger connected to a heating grid having a feed conduit for an incoming flow of heat transfer fluid having a first temperature in the range of 50-120° C., and a return conduit for a return flow of heat transfer fluid having a second temperature, the second temperature being lower than the first temperature, wherein the central heat exchanger is configured to exchange heat from the incoming flow of heat transfer fluid to an outgoing flow of local heat transfer fluid in the local feed conduit. The system also includes a plurality of local heating systems, each having an inlet connected to the local feed conduit and an outlet connected to the local return conduit, wherein each local heating system is configured to provide hot water and/or comfort heating to a building.
