Problems solved by technology

[0004] 1) The indoor temperature and humidity sensor or the temperature and humidity sensor at the return air outlet cannot accurately reflect the temperature and humidity of the most unfavorable point in the room under various working conditions, and cannot start and stop the refrigeration system according to the control of the temperature and humidity sensor;
[0005] 2) There is a delay in indoor temperature control. It takes a long time from the detection of temperature rise to timely disposal, and it is easy to cause downtime during the process of increasing cooling input and cooling;
[0006] 3) Predictive control of dynamic changes in indoor air parameters due to changes in the computing power occupancy of the cabinets and changes in outdoor meteorological parameters are not considered, and there is room for further reduction of PUE;
[0007] 4) The problem of uneven distribution of indoor air parameters caused by airflow organization and different cabinet computing power occupancy is not considered, and the uneven distribution will change in real time. The existing technology cannot reflect the distribution of the indoor temperature field in real time. And carry out more energy-saving control, there is room for further reduction of PUE;
[0008] 5) In view of the fluctuating CPU usage in the data center, the air conditioning system cannot perform self-adaptive adjustments, resulting in large horse-drawn carts and a waste of energy
