Data centers are usually composed of cabinets, Internet Technology (IT) servers, uninterruptible power supply (Uninterruptible Power Supply, UPS), temperature control equipment, temperature and humidity sensors and other equipment. The above IT equipment will emit a lot of heat during operation. Considering the use requirements of the data center in different scenarios, the number of temperature control devices in the data center is usually redundant. Since the temperature control devices in the data center work independently, there may be competition between them. For example, when some temperature control devices are cooling, other temperature control devices are heating, which will cause waste of electric energy; in addition, In order to save electric energy, the temperature control equipment in redundant state should be made to stand by, and to realize the above functions, it is necessary to carry out group control of temperature control equipment. Group control of temperature control equipment refers to connecting temperature control equipment and other sensing elements to the control center, grasping various data in the data center through various sensing elements, and then formulating a scientific control strategy, and controlling the temperature according to the above control strategy Temperature control equipment is used to control the temperature to achieve better energy saving and environmental control effects.

The cooling load of the data center changes dynamically. The above-mentioned existing temperature control equipment group control scheme cannot adjust the operating temperature control equipment combination according to the cooling load, which will cause energy waste.
