1results about How to "Small control deviation" patented technology

This invention relates to the field of air conditioning technology, providing an air conditioning control method, device, and system. The method includes: acquiring historical temperature data, which includes predicted indoor temperature values ​​and corresponding measured indoor temperature values ​​at multiple sampling times; determining a temperature prediction error parameter based on the difference between the predicted indoor temperature value and the corresponding measured indoor temperature value; predicting the predicted indoor temperature value at the next time moment; and adjusting the compressor's operating frequency based on the predicted indoor temperature value at the next time moment, the temperature prediction error parameter, and the target indoor temperature. This invention, by acquiring predicted and measured indoor temperature values ​​at multiple sampling times from historical data and determining a temperature prediction error parameter based on the difference between the two, corrects the predicted temperature value at the next time moment. This reduces deviations caused by inherent biases in the temperature prediction model or environmental interference, avoids excessive compressor adjustment or adjustment lag, improves user comfort, and reduces overall energy consumption.
