AI Technical Summary
Traditional air conditioning systems cannot dynamically generate matching operating parameters when operating points and loads change, resulting in the compressor's target frequency being too low or too high during the initial operation phase, leading to inaccurate temperature regulation and frequent start-stop problems.
By employing a load estimation unit, a temperature estimation unit, a superheat estimation unit, and an opening estimation unit, and by acquiring the load of the air-conditioned area and the required evaporation temperature, the compressor frequency and the opening of the electronic expansion valve are dynamically adjusted to achieve more precise control.
It improves the adjustment accuracy of the air conditioning system under different loads and operating points, reduces temperature fluctuations and frequent compressor start-stop, and achieves more flexible and intelligent control.
