Description

A kind of computer room or base station flood irrigation formula air-conditioning adaptive energy-saving control system and method

Technical field

The present invention relates to a kind of computer room or base station flood irrigation formula air-conditioning adaptive energy-saving control systems and method.

Background technology

Equipment in computer room and base station is mainly made of a large amount of microelectronics, accurate mechanical equipment etc., and this A little equipment have used a large amount of electronic component, mechanical component and the material easily influenced by temperature, humidity.Computer room and base station are accurate Air-conditioning can realize it is stringent, be accurately controlled computer room temperature and relative humidity, to substantially increase service life and the reliability of equipment. With the development of information technology, current computer floor and base station scale are constantly developing, extensive, highdensity because possessing The energy consumption of deployed with devices, computer room and base station air conditioner is also huge.For data center, the fortune of air conditioner in machine room Row power consumption accounts for 50% or more of computer room electricity charge total amount.Therefore, realize that computer room and base station air conditioner energy-saving run are of great significance.

Currently, in the existing computer room in China and base station, the mode of flood irrigation formula air-supply is largely used, which is air-conditioning Unit is directly blown (no air hose) between IT heat-producing devices by the upper end blast cap, then logical from the lower end of air-conditioning equipment or side leading wind Cross the upper end blast cap directly between IT heat-producing devices blow (no air hose), then from air-conditioner set by the upper end blast cap directly to IT It blows (no air hose) between heat-producing device, then from the direct return air (nothing in the lower end or side air port of the lower end of air-conditioning equipment or side leading wind Air hose).The air current composition of this air supply mode is more chaotic, and hot and cold there are unordered mixing, and the cold of machine room area is caused to distribute Unevenness, air-conditioner set are directly blown (no air hose) between IT heat-producing devices by the upper end blast cap, then from the lower end of air-conditioning equipment Or the refrigerating capacity of side leading wind cannot be fully utilized, system energy consumption is higher.Meanwhile local I T equipment cannot be sufficiently cooled, and be gone out Existing hot-spot, influences the safe operation of information technoloy equipment.

On the other hand, air-conditioner set used in the in-service flood irrigation formula computer room in China and base station by the upper end blast cap directly to It blows (no air hose) between IT heat-producing devices, then still largely using the cabinet type of constant speed drive from the lower end of air-conditioning equipment or side leading wind Air conditioner or constant speed cabinet type fan coiler.Refrigeration compressor, wind turbine or water pump therein are set according to power frequency operation by monitoring IT Standby temperature data, the start-stop control for carrying out air conditioner number of units, to realize the response regulation to computer room thermic load.This start-stop control The varying capacity regulative mode of system, on the one hand due to frequent start-stop when energy consumption is big, it is big to be damaged to the operation of air conditioner service life;Another aspect nothing The in due course elimination local devices hot spot of method, influences the operational reliability of information technoloy equipment, and air-conditioner set and system equipment energy saving in running Effect is very undesirable.

The solution of process data center computer room hot spot elimination exists in the prior art:It is that load space is subjected to more piece Point divides, and by Air-condition system control, the temperature of surface air-supply, air draft air-flow based on each space nodes passes node region temperature Feel output signal, by network system adjust air-conditioner set by the upper end blast cap directly between IT heat-producing devices blow it is (calm Pipe), then from the lower end of air-conditioning equipment or side leading wind draft capacity, further cooling, wind is sent to by respective nodes by air hose, with Realize the elimination of the equipment hot spot of node region.This is eliminated for air duct blow type computer room and base station air conditioner system hot spot One of settling mode, but the program can not solve the flood irrigation formula computer room of no air duct blow and the hot spot of base station and energy saving.Using The program cannot achieve runs air-conditioning system under the premise of being changed without air-conditioner set and system equipment to in-service a large amount of constant speed Implement the requirement of reducing energy consumption.
