How to make less of electricity through the data center, and the server rack

, the rapid development of modern society, the data room of the enterprise data center room is the 'users' power consumption, how to make less of electricity through the data center, and the server cabinet guaranteed, as a result of the need of computer equipment run 24 hours a day all the year round, the computer room floor to independent air-conditioning control system, and to satisfy the environment temperature, humidity, air dust concentration of technical requirements, technical support for computer room environment conditions of other equipment, coupled with the power of the computer device itself and a room total power load.
so, under the circumstances of the country's electricity tension, enterprise data center room for energy saving is urgently needed. Look from the computer room power distribution, IT equipment accounted for 44% of the total energy consumption, cooling, electrical energy system and a 38% to 15%, power supply system, lighting system, accounting for 3%. In the case of IT equipment power cannot be cut, just need to find a way to save electricity from the refrigeration system and power system.
in the engine room, in addition to the essential IT load, the power consumption of air conditioning refrigeration equipment in second place. According to the analysis, a typical data center at the time of initial investment, refrigeration equipment accounts for only 6% of the amount of investment, but its late electricity expenses can account for 38% of the whole data center electricity expenses, is a standard form of 'and power-hungry. Therefore, select high efficiency and energy saving of refrigeration system, computer room precision is the data center must consider the question.
in the design of refrigeration system solutions, should put the whole data center room as a whole, fully considering the energy saving from the each link. Launched by APC NetworkAir precision refrigeration solutions, for example, it adopts the modular design, control the average temperature, humidity, each module in the system will detect the information sent to the main controller of temperature, humidity, average temperature, humidity, the main controller, feedback the information to the various modules. So after a unified operating mode, to avoid the part of the caused by different temperature and humidity difference between air conditioning part in another part in the heating, refrigeration and air conditioning in another part in humidification and dehumidification, thus preventing the conflict caused by the low efficiency of operation.
besides precision refrigeration system itself, in the planning of the room as a whole should be fully considered how to energy saving province electricity. Refrigeration system efficiency is the key to effective distinguish between cold and hot air, ensure the cabinet internal IT equipment can work under normal temperature. The APC proposed unique 'thermal channel ( 热通道) 'and' cold channels ( 冷通道) Concept, change the previous data center cabinet surface approach is put in the same direction, using the 'face to face, back to back cabinet put way, thus conform to the servers and other IT equipment from the front into the wind, the design of the exhaust air from behind, effectively turning cold and hot air partitions, avoid the hot air from the front cabinet is mixed with cold air into the rear cabinet results in the decrease of cooling effect.
in the typical data center, the refrigeration efficiency if reduce 20%, can lead to the entire power consumption increased by 8%. But if the plan is reasonable, the room of the refrigeration system can energy saving 20% ~ 30%, which reduced about 10% of the total power consumption. Power supply system for energy saving
look from the room the proportion of electricity distribution, the power consumption of the power supply system itself also accounted for the proportion of 15%, the utilization ratio of UPS height will directly affect the size of the power consumption. With APC company Silcon ( Silcon) UPS, for example, the input power factor is 0. 99, with the input power factor is 0. Compared to 8 UPS, greatly reduces the reactive power in the system and the corresponding loss. Tell from UPS itself efficiency, Silcon of APC UPS work efficiency is as high as 97%, its power consumption is less than 3%. UPS its efficiency is low, must increase the overall power consumption, electricity spending increased. In addition, if consider UPS and oil machine cooperate relationship, Silcon UPS APC also has a strong advantage in energy saving. 40 kva system, for example, if the use of APC products with oil machine, because the UPS power input up to 0. 99, for the oil machine, UPS is a purely resistive load, so you just need to 50 ~ 60 kw generator, UPS and oil machine ratio is 1:1. 3.
