Method and device for internet-based optimization of parameters of heating control

A system (1) for determining a set of optimized control parameters (Θk) of a closed-loop controller (3) or an open-loop controller for an HVACR (heating, ventilation, air conditioning and refrigeration) system (2) comprising:

• an outside temperature sensor (11) for detecting an outside temperature (TA);
• a room temperature sensor (10) for detecting an actual room temperature (TR), which is arranged in a room (9);
• a supply temperature sensor (12) for detecting a supply temperature (TA);
• an apparatus (17) for presetting a target room temperature (TR, w);
• an apparatus (4) for presetting a target supply temperature (TVL, W);
• an apparatus (22) for generating a data packet (Dk) with the detected measured values (TA, TR, TR,W, TVL, TVL,W) and a time (tk) of detection;
• a transmission apparatus having an interface (20) for transmitting the data packet (Dk) to a server (8) via an internet connection;
• and
• a storage medium (6, 7) connected to the server (8) for storing the data packet (Dk);
• wherein the server (8) has a processor (CPU) configured to:
• calculate a set of optimized control parameters (Θk) on the basis of measured values (TA, TR, TR,W, TVL, TVL,W) of the transmitted and stored data packet (Dk) of the point in time (tk) and on the basis of:
• measured values (TA, TR, TR,W, TVL, TVL,W) of a plurality of further data packets (D0 . . . k-1) generated at earlier times (t0 . . . k-1) of a specified time period (Δt);
• and/or
• at least one of a plurality of previously determined sets of control parameters (Θk-1);
• execute a calculation algorithm for calculating the set of optimized control parameters (Θk) by
• determining a first deviation (eR) between actual room temperature (TR) and target room temperature (TR,W) for each data packet (D0 . . . k) of a predefined time period (Δt),
• determining a second deviation (eVL) between supply temperature (TR) and predefined supply temperature (TVL, W) for each data packet (D0 . . . k) of the predefined time period (Δt), and
• determining and applying a weighting factor (w) between 0 and 1 on the basis of the determined deviations (eR, eVL), so that, when calculating the set of optimized control parameters (Θk), data packets (D0 . . . k) with low deviation are taken more into account and data packets (D0 . . . k) with high deviation are taken less into account;
• store the calculated set of optimized control parameters (Θk) in the storage medium (6, 7) connected to the server (8);
• and
• transmit the calculated set of optimized control parameters (Θk) via an interface (21) via the internet connection to the closed-loop controller (3) or the open-loop controller of the HVACR system (2) and adopt the set of optimized control parameters (Θk) by the closed-loop controller (3) or the open-loop controller of the HVACR system (2), or
• send a notification with the calculated set of optimized control parameters (Ok) to a user (B) of the HVACR system (2) and, if the user (B) confirms the set of optimized control parameters (Θk), adopt the set of optimized control parameters (Θk) on the closed-loop controller (3) or the open-loop controller of the HVACR system (2).
