Abrégé

A controller configured to selectively set a reversible heat pump assembly (100) in either a heating mode or in a cooling mode is presented. The controller comprising a control circuit (44) configured to: for a time period, determine, using a demand determining function (50), a heating demand for heat from one or more local heating circuits (140) connected to the reversible heat pump assembly (100) and a cooling demand for cold from one or more local cooling circuits (140) connected to the reversible heat pump assembly (100); generate, using a control function (52), a control signal indicative of if the reversible heat pump assembly (100) is to be set in either the heating mode or in the cooling mode, wherein the control function is configured to use the heating demand and the cooling demand as input data; and send, using a transmission function (54), the control signal to a heat pump (110) of the reversible heat pump assembly (100). Also a method for controlling the reversible heat pump assembly (100) is presented.

Abrégé

The present invention relates to a flow controller configured to selectively act as a pump or as a flow regulator. The flow controller includes an inlet for a fluid; an outlet for the fluid; a pump assembly arranged between the inlet and the outlet and configured to pump the fluid through the flow controller; a hydro electrical generator assembly arranged between the inlet and the outlet, the hydro electrical generator assembly being configured to allow the fluid flow through the flow controller and to generate electricity by transforming flow energy of the fluid flowing through the flow controller into electricity; and a mode controller configured to selectively set the flow controller in a pumping mode to deactivate the hydro electrical generator assembly and to activate the pump assembly, or in an electricity generating mode to deactivate the pump assembly and to activate the hydro electrical generator assembly.
