With the rise of the cloud computing big data industry, the heat of data center construction is increasing.
The construction area of data center equipment rooms is getting larger and larger, and the power density of IT equipment in the equipment rooms is getting higher and higher. So much IT equipment naturally puts pressure on data center energy conservation. Although the current data center related technologies such as cooling, modularization, and intelligent operation and maintenance are developing rapidly, the energy saving of the computer room still faces great challenges.
data center room
For the energy saving of the computer room, the following 13 small methods are summarized for your reference:
1. The energy-consuming computer room is placed in the middle of the building through a group design. The auxiliary functional rooms such as battery power and air conditioner wrap the data computer room to form a sandwich structure.
2. The original windows of the computer room are blocked to reduce the loss of air conditioners and outdoor solar heat radiation. This part has great potential to reduce energy consumption, and the energy saving efficiency reaches 15%.
3. The walls of the computer room are treated with thermal insulation, heat insulation and moisture-proof materials to reduce indoor cold exchange, which can save about 5% of energy.
4. The doors and windows with anti-sealing treatment can reduce any heat-transfer bridges, which can reduce energy consumption by about 3%.
5. The water-cooled central air-conditioning system is adopted, which saves 15% of the overall energy consumption compared with the air-cooled precision air conditioner. In the data center computer room, a special large-scale water-cooled computer room precision air conditioner and chip cooling pipes are built to directly dissipate heat for the IT equipment chips.
6. In the form of downward air supply, special cabinets for downward air supply are used, arranged in a back-to-back manner. The cold air is fed in at the front of the bottom of the cabinet, and the hot air is discharged at the back of the data cabinet after entering the data equipment. Save 30%.
7. Set up a raised floor and adjust the opening of the floor air outlet according to the heat load of the rack, which can reduce the overall air supply volume by 20% and save the energy consumption of the air-conditioning fan.
8. In order to prevent condensation on the ground, the ground is insulated with B1-grade foamed rubber-plastic insulation material with aluminum foil with a thickness of 19mm.
9. The central air-conditioning system is controlled by the BA system, which can realize remote monitoring and unattended operation. During operation, the on-off of the air-conditioning host can be adjusted according to the load of the air-conditioning, saving energy consumption.
10. Make full use of the local extranet to save investment and operating costs;
11. Reasonably arrange the location of the high and low voltage power distribution room and the UPS battery power room, close to the load center, shorten the power supply line, reduce line loss, and reduce operating costs.
12. Reasonably select the equipment system, increase its load rate, keep the equipment in an economical operation state, and reduce its reactive power loss, such as: install capacitors on the low-voltage side of the power transformation and distribution room, and perform reactive power compensation to improve the transformer utilization rate and reduce Reactive power loss; reasonably select the transformer to increase its load rate, so that the transformer is in an economical operation state.
13. Reasonably determine the illuminance standard, and use high-efficiency and energy-saving lighting fixtures and electronic accessories with low loss and excellent performance.
Data centers are large consumers of electricity, so saving electricity is the focus of energy conservation and emission reduction. In addition to adopting planning and design solutions to save energy, we should also choose appropriate materials, air-conditioning systems, and pay attention to building thermal insulation and thermal insulation, all of which will play a significant role in realizing the energy saving of data centers.
