Abstract

The invention relates to the technical field of refrigeration and discloses a refrigeration control method and device for a machine room. The refrigeration control method for the machine room comprises the steps that current return air temperatures and current supply air temperatures of all indoor units of air conditioners are received; and the rotating speed of fans and the rotating speed of compressors (or the opening degree of a water valve) are adjusted according to the corresponding relation of a stored target return air temperature, the rotating speed of the fans of all the indoor units with a calibrated target supply air temperature and the rotating speed of the compressors of compressor air conditioners (or the opening degree of the water valve of a chilled water air conditioner) when the current return air temperature is not equal to the target return air temperature, so that the current return air temperature is adjusted to the target return temperature, and the current supply air temperature is adjusted to the target supply air temperature. According to the technical scheme, the adjustment range of the refrigerating capacity of the air conditioners can be enlarged, and the stability of refrigeration control is improved.

Description

technical field

[0001] The invention relates to the technical field of refrigeration, in particular to a refrigeration control method and device for a machine room. Background technique

[0002] A data center, commonly known as a computer room, is a complete set of complex facilities. It not only includes computer systems and other supporting equipment (such as communication and storage systems), but also includes redundant data communication connections, environmental control equipment, monitoring equipment, and various safety devices. In existing data centers, energy costs account for a relatively high proportion of computer room operating costs, and less than half of the electricity is used for IT loads, while the rest is used for infrastructure such as power supply and cooling systems.

[0003] At present, most computer rooms use air conditioners installed between servers as cooling equipment. Air conditioners are close to heat source air conditioners. The cooling effi...
