Abstract

The invention discloses a machine room air conditioner system control method. The air return temperature or / and the air return humidity of each started air conditioner is / are obtained at the intervalof the first preset time; the average air return temperature or / and the average air return humidity is / are calculated; running of each started air conditioner is controlled according to the average air return temperature and the target temperature set value, or / and running of each started air conditioner is controlled according to the average air return temperature and the target humidity set value. Accordingly, the problem of local hot spots in a machine room is solved, stability of temperature or / and the humidity in the machine room is kept, a stable running environment is provided for electronic equipment in the machine room, and meanwhile the purpose of energy saving is achieved.

Description

technical field [0001] The invention belongs to the technical field of computer room air conditioners, and in particular relates to a control method for a computer room air conditioner system. Background technique [0002] With the development of the economy, the electronic communication industry is developing rapidly, and the area of ​​the corresponding electronic equipment room is getting larger and larger. The number of electronic cabinets in a room is gradually increasing, and it has developed from a small data center to a built-in dozens or even hundreds of electronic cabinets. Large or very large IDC data centers. Due to the increase in room area, the increase in the number of cabinets and the different power loads of each cabinet, and the unreasonable arrangement of cooling air conditioners in the room, it is easy to cause local hot spots in the room of a large data computer room, and one or more positions in the room cannot be obtained. Effective cooling causes the ...
