  • Patent number: 12281802
    Abstract: Disclosed is a method for controlling a control valve (110), wherein the control valve (110) is configured to control a flow of heat transfer fluid to a thermal energy extraction unit (108). The method comprising: reviewing (S402) a demand signal for the control valve (110); checking (S404) if the demand signal is indicative of setting the control valve (110) in a hysteresis interval for the control valve (110); and upon the demand signal is indicative of setting the control valve (110) in the hysteresis interval, alternatingly (S406) setting the control valve (110) in an open state above the hysteresis interval and setting the control valve (110) in a closed state.

  • Publication number: 20230213212
    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.
