Highlights Summary:

"1" UPS power supply system is the trend of DC;

The reliability of the "2" data center depends on the reliability of the UPS;

"3" high modular ups, as well as system redundancy structure, improve reliability, and intelligent management, and then one is the entire integrated system. All UPS power supply manufacturers, probably in this regard.

"4" The current system basic condition: The basic condition is the system unceasingly complicated, the equipment accumulation structure is bloated, the cost unceasingly climbs, the efficiency is difficult to improve effectively, the specification multifarious is difficult to standardize.

"5" Current system problems: the first is the reliability of the problem, the second is the problem of coercive interference, the third is the problem of energy consumption, the Forth is the standardization of the problem, the sixth is the flexibility of the problem, and maintenance of difficulty.

The reliability of "6" in the DC UPS system depends entirely on the standby battery.

"7" DC voltage Selection Principle: The first does not require it output switch to make significant changes, and secondly to simplify the equipment, repeat the change of things; third, the adaptability of the IT equipment, as well as energy-saving and security issues, the higher the security the better.

"8" power supply Scheme Selection principle: To improve the reliability of the system as a first requirement, the key is the standby battery direct power supply, as far as possible to reduce the conversion series. Pay attention to DC distribution, and finally design ups from the whole system angle.

Highlights Summary:

"1" module machine must be a high-quality, miniaturized, digital, modular. is also environmentally friendly.

"2" Modular machine has an important choice is to control the way, can be divided into two points, one is centralized control, there is a decentralized control technology. The centralized control technology is each module in the parallel process, the parallel foundation is the synchronization, in order to complete the synchronization, needs to have a signal source, this signal source is one centralism, may also be a dispersed. Using a decentralized model, the system will be considered better.

"3" We developed a small, scaffolding, decentralized ups, you can single out, three into three, in this system mainframe, power distribution, batteries, TPU can be configured according to needs. This is our data center, industrial applications more products, can be from 10K to 480K, module power from 10K, 20K, 40K, and then can meet the ITC room provided by the integrated data distribution points, integrated intelligent, the use of modular structure.

"4" module opportunities to improve reliability, because the principle of improving reliability is to improve the use of time and redundancy, the modular machine to meet this need.

"5" As a data center UPS power supply, there are generally 4 levels of standards, T1 standard is a single UPS framework. T2 Standard has two types, one is series, one is parallel, in any case to its standard is redundant, this is the standard for T2. The T3 scheme configuration is distributed. In other words, there is an independent space between the physical space and the output input, but there may be a unified redundancy framework. The greatest benefit, the requirement is uninterrupted maintenance. T4 standard should be called Double Busbar 2N power supply, this method has better fault tolerance. This is four standards, and we can have better standards for both fault tolerance and redundancy, as well as extensions. This feature can be implemented using modular ups.

Highlights Summary:

"1" Data center energy consumption is mainly divided into three aspects, a solution to cooling cooling, an IT equipment, there is a power system.

"2" meter Kang Company's energy-saving technology:

1, heat island cooling technology, now a large number of data center status of the formation of Heat island at the same time, some areas of excessive refrigeration, distribution is very uneven, how to solve this problem? The use of heat island cooling technology, such as coupled with accurate air supply, precision temperature control system, mainly for the traditional large-scale data center solutions. In addition, night air conditioning coupled with accurate temperature control system This is point-to-point refrigeration, mainly to solve the problem of local overheating data center.

2, hot and cold channel technology. Now in the data center, we know that the short cycle caused by the lack of cooling, excessive air supply distance caused by the remote cabinet into the air shortage, the air return distance too long lead to hot and cold channel airflow mixing to reduce air-conditioning efficiency, cabinet up and down hot and cold uneven. The closed cold passage measures are adopted to effectively isolate the cold and hot airflow and ensure that the limited cold air enters the computer equipment to achieve the desired refrigeration effect. The energy saving of air conditioner can reach 10%, the total energy consumption can reduce 3.7% energy consumption.

3, natural cooling energy-saving technology. Natural cooling of the host to energy-saving patented design, the winter natural shutdown compressor, through the control system to switch host remote refrigeration, can greatly reduce the power consumption of the machine, energy-saving effect in a specific area is very obvious, water-cooled and air-cooled units can be natural cooling.

4, dual-power energy-saving technology. Integrated fluorine pump energy-saving and compressor refrigeration heat transfer technology, the technical input is relatively small, easy to transform, this technology for the old room transformation is very practical, product module installed outdoors, not limited by indoor space, its energy-saving effect and ordinary unit compared to the whole year save energy is very large.

4. EC fan Energy-saving technology. Ordinary fan transmission power and EC fan transmission power are the same, but the energy-saving effect is very good.

5, improve the freezing water temperature and energy saving technology. Under certain working conditions, it can improve the freezing water temperature technology, effectively improve the energy efficiency of chillers, use the equipment scheme, under the same conditions, the annual energy saving is very considerable.

6, improve the air return temperature energy-saving technology. Can improve the intelligent system evaporation temperature and pressure, so that the unit refrigeration capacity and energy efficiency are effectively improved to achieve energy-saving purposes. When the air return is under certain circumstances, the energy-saving effect of air-conditioning and the stability of the computer room can achieve a very favorable balance, energy-saving effect is very good.

7. Comprehensive application. The traditional unit uses heat island cooling + hot and cold Channel + Power + to improve the return air temperature combination of use, air-conditioning equipment energy consumption accounted for the proportion of room energy can be as low as 22%, the room Pue value reached 1.8 below. For chilled water units, the use of heat island cooling + hot and cold channel +ec fan + to improve the combination of frozen hydrology, energy consumption can be less than 10.7%.
