  • Patent number: 11306933
    Abstract: The present invention relates to a method for determining a set of optimized control parameters (?k) of a closed-loop controller (3) or an open-loop controller for an HVACR (heating, ventilation, air conditioning and refrigeration) system (2). In a first method step, an outside temperature (TA), an actual room temperature (TR) of a room (9), a supply temperature (TVL), a predefined target room temperature (TR,W), and a predefined target supply temperature (TVL,W) are detected. From the detected measured values (TA, TR, TR,W, TVL, TVL,W) and a time (tk) of detection data packet (Dk) is generated, which is transmitted via an internet connection to a server (8) where the data packet (Dk) is stored in a storage medium (6, 7) connected to the server (8).

  • Patent number: 11079729
    Abstract: A method is provided for controlling a multivalent energy supply system including at least two energy generators using at least two different energy carriers to provide heat, cold, and/or electrical energy. For each generator, a closed-loop controller controls variables of the generator. Each generator assumes one of three possible switching states: the generator must be switched on, must be switched off, or may be switched on or off. The system includes a control device for coordinatedly controlling the closed-loop controllers. The control device detects at least one request for heat and/or cold and/or electrical energy and determines whether a specific criterion is present which specifies exactly one of the three possible switching states for each generator. The control device determines target values for meeting the request depending on the request and the specific criterion and outputs the target values to the closed-loop controllers.

  • Patent number: 10704785
    Abstract: The invention proposes a method for the flame signal detection by means of an ionization electrode (15) protruding into a combustion zone of a burner, comprising the steps: detecting a first signal, which is dependent on an ionization current flowing off the ionization electrode (15), generating a second signal which has a predetermined periodic course, generating a third signal by adding the first signal and the second signal, comparing the third signal with a first threshold value and generating a fourth signal on the basis of the comparison of the third signal with the first threshold value, comparing the third signal with a second threshold value different from the first threshold value and generating a fourth signal on the basis of the comparison of the third signal with the second threshold value, and determining an operating variable of the burner on the basis of at least one of the fourth signal and the fifth signal.

  • Patent number: 10699352
    Abstract: The invention relates to a method of controlling an energy supply system comprising at least two energy generators each configured to provide at least one form of energy of heat and/or cold and/or electrical energy. The energy supply system further comprises one closed-loop controller per energy generator for controlling the energy generator and a control device coordinatedly controlling the closed-loop controllers. The control device detects an energy supply request for providing energy in the form of heat and/or cold and/or electrical energy and determines for each energy form which energy generators are required to meet the energy supply request. For each energy form, the control device generates switch-on requests for the energy generators required to meet the energy supply system and switch-off requests for the energy generators not required.
