Problems solved by technology
[0004] However, each air conditioner is individually controlled according to the temperature and humidity requirements. When the load distribution of the modular data center is uneven, some computer room air conditioners may be turned on and run at high frequency for a long time, while some air conditioners may be turned off for a long time, or some air conditioners may start and stop frequently, reducing The operation reliability of the air conditioner in the computer room is improved; in addition, because the temperature feedback control is relatively hysteresis and the heat transfer is delayed, the control delay of the air conditioner is poor in real time

Embodiment Construction
[0032] Currently, air conditioners in data centers are independently controlled according to temperature and humidity requirements. Usually, the load distribution of the data center is not uniform, which leads to the fact that the control of the air conditioners in the data center does not meet the actual demand in the data, resulting in the uneven operation of each air conditioner and reducing the reliability of the air conditioner operation; in addition, the transmission of temperature and humidity exists Hysteresis will also result in poor real-time control of the air conditioner.
[0033] Based on this, the basic principle of this application is as follows: the cooling capacity demand of the data center is allocated to each air conditioner in the data center according to the load of the data center and the distribution position of the air conditioners, so as to realize the balanced operation of each air conditioner and improve the operation efficiency of the air conditioner...

An embodiment of the invention discloses an air conditioner control method and device, relates to the field of air conditioner control, and realizes air conditioner control on improving the air conditioner running reliability and instantaneity. According to the specific scheme, the overall refrigerating capacity, as shown in the specification, of each air conditioner of N air conditioners at the moment t is acquired; the power pj,t of each server cabinet at the moment t is acquired; the refrigerating capacity proportion of each air conditioner is calculated according to the load of a data center; the target refrigerating capacity of each air conditioner is calculated by the air conditioner control device; and the N air conditioners are controlled to reach respective target refrigerating capacity. The air conditioner control method and device are applied to the process of air conditioner control.
Description
technical field [0001] The present application relates to the field of air conditioning control, and in particular, to an air conditioning control method and device. Background technique [0002] With the advent of the era of big data, the amount of data processing continues to rise, and modular data centers are rapidly expanding. The modular data center consists of multiple computer room air conditioners and multiple IT server cabinets. A large amount of heat is generated during the operation of the IT server cabinet, which is carried by the computer room air conditioner to the outside to ensure a constant temperature in the modular data center. Therefore, it has become a general trend that the modular data center controls multiple air conditioners in the computer room and effectively reduces the power usage efficiency (PUE) of the entire modular data center. [0003] At present, the control method of traditional modular data center air conditioners is relatively simple. ...
