Abstract:

Currently, the energy consumption of data centers has become increasingly prominent. The HVAC system accounts for a significant proportion of total energy use, with the cooling system being the key to energy saving. Traditional cooling system control methods are simplistic and cannot fully utilize external natural cooling sources. This paper proposes an intelligent control method for cooling towers based on the composite control of wet-bulb temperature and water vapor partial pressure. By dynamically adjusting fan speed, the cooling system can adaptively match external climatic conditions. Experiments and applications show that this method can significantly improve cooling system efficiency, reduce PUE values, and provide technical support for green and low-carbon operation of data centers.
