Description
Technical Field
The invention relates to an adaptive energy-saving control system and method for a machine room or base station flood irrigation type air conditioner.
Background
The equipment in computer rooms and base stations is mainly composed of a large number of micro-electronic, precision mechanical equipment, etc. which use a large number of electronic components, mechanical members and materials that are susceptible to temperature and humidity. The machine room and the base station precise air conditioner can strictly and precisely control the temperature and the relative humidity of the machine room, so that the service life and the reliability of equipment are greatly improved. With the development of information technology, the scale of the current computer room and base station is continuously developed, and the energy consumption of the air conditioner of the computer room and the base station is huge due to the large-scale and high-density equipment deployment. Especially for a data center, the operation power consumption of the air conditioner in the machine room accounts for more than 50% of the total electricity charge of the machine room. Therefore, the realization of the energy-saving operation of the air conditioners in the machine room and the base station is of great significance.
At present, in the existing machine rooms and base stations in China, a large number of air supply modes of flood filling are adopted, wherein the air supply modes include that an air conditioning unit directly supplies air to an IT heating equipment room through an upper end air cap (without an air pipe), then directly supplies air to the IT heating equipment room through an upper end air cap from the lower end or side surface air of the air conditioning equipment (without the air pipe), then directly supplies air to the IT heating equipment room through an upper end air cap from the air conditioning unit (without the air pipe), and then directly returns air from the lower end of the air conditioning equipment or the lower end or side surface air opening of the side surface air (without the air pipe. The air supply mode has disordered airflow organization, cold and heat are mixed disorderly, cold quantity distribution in a machine room area is uneven, the air conditioning unit directly supplies air (without an air pipe) to IT heating equipment rooms through an upper end hood of the air conditioning unit, refrigerating capacity of air from the lower end or the side face of the air conditioning equipment cannot be fully utilized, and energy consumption of a system is high. Meanwhile, local IT equipment cannot be sufficiently cooled, and local overheating occurs, so that the safe operation of the IT equipment is influenced.
On the other hand, air conditioning units used in the in-service flood irrigation machine rooms and base stations in China directly supply air (without an air pipe) to IT heating equipment rooms through upper end hoods, and then cabinet air conditioners or constant-speed cabinet type fan coils which run at constant speed are still largely used in the air from the lower ends or the side faces of the air conditioning equipment. The refrigeration compressor, the fan or the water pump operate according to power frequency, and response adjustment of heat load of a machine room is achieved by monitoring temperature data of IT equipment and controlling starting and stopping of the number of air conditioners. On one hand, the variable capacity adjusting mode of start-stop control has large energy consumption and large damage to the service life of the air conditioner due to frequent start-stop; on the other hand, local equipment hot spots cannot be eliminated timely, the operation reliability of the IT equipment is influenced, and the energy-saving effect of the operation of the air conditioning unit and the system equipment is not ideal.
The prior art has a solution for processing the elimination of hot spots in a data center machine room: the load space is divided into a plurality of nodes, the temperature of the node area is controlled by an air conditioning system, based on the temperature sensing output signals of the surface air supply and exhaust air flow of each space node, the air conditioning unit is adjusted through a network system to directly supply air (without an air pipe) to IT heating equipment through an upper end hood of the air conditioning unit, then the air supply capacity and the temperature are further reduced from the lower end or the side surface of the air conditioning equipment, and the air is supplied to the corresponding node through the air pipe, so that the equipment hot spot of the area where the node is located is eliminated. The method is one of solving means for eliminating hot spots of air pipe blowing type machine rooms and base station air conditioning systems, but the scheme cannot solve the hot spots and energy conservation of air pipe blowing-free flood irrigation type machine rooms and base stations. By adopting the scheme, the requirement of implementing energy-saving reconstruction on a large number of air conditioning systems running at constant speed in service on the premise of not replacing air conditioning units and system equipment can not be realized.
