Description

Technical Field

[0001] The present invention relates to the field of control technology, and in particular to an air source heat pump control method and control system. Background Art

[0002] In the air source heat pump control method and system, an effective energy consumption control method can not only significantly reduce energy consumption, but also extend the life of the equipment and ensure the stability and economy of the system operation. However, in practical applications, the existing methods and systems often have limited adaptability to different environmental conditions and cannot optimize energy use in real time. There are problems such as large fluctuations in energy efficiency and waste of resources. In addition, in terms of energy consumption prediction and adjustment, the system relies too much on static data, resulting in insufficient accuracy of energy consumption control, affecting the efficiency and energy-saving effect of the overall system, and making it impossible to achieve the expected energy saving goals.

[0003] In the Chinese invention application with application publication number CN109543903A, a method and system for predicting energy consumption of an air source heat pump is disclosed, which belongs to the field of household appliances. By counting parameters such as room area, number of rooms, region, required water temperature, maintenance structure, etc., the database is sorted, the corresponding model of air source heat pump is selected, the water supply temperature is set according to user habits, and the hourly heat load data at each time of the year is calculated to see whether the result matches the database. If it matches, it is directly called. If it does not match, the interpolation method is used for calculation. The annual energy consumption of the air source heat pump can be quickly calculated.

[0004] In the above invention, although the calculation time can be greatly reduced and the efficiency can be improved by matching with the historical data in the database, and the interpolation method can provide reasonable prediction results even in the case of data mismatch, this method relies on the accuracy and completeness of the database. If the historical data in the database is insufficient or not accurate enough, it will affect the accuracy of the matching and the reliability of the prediction results. In addition, the interpolation method will introduce errors when dealing with data mismatches, especially in boundary conditions or extreme cases, and the accuracy of the prediction results may be affected.
