Currently used micro module data center industry is mainly used in indoor scene, mainly by the end of the IT equipment, air conditioning, high voltage dc between columns, modular UPS, cold channels such as micro module products;The container type data center is mainly used for outdoor scene, mainly IT box, distribution box, cold case, firewood box, office box, etc.The former has been deployed on a large scale, but only for the end devices of IDC and lacks mobility.The latter is easy to move and flexible to build, but with a limited scale, combining the two can create a faster and more flexible way to build large data centers.
Data center of the main modules such as IT, supporting infrastructure (power, air conditioning, weak current, etc.), engineering (building, office, etc.) according to the optimal model of form a complete set and construction methodology to develop a standard interface for the transition, in the form of container product as the carrier in advance within the factory prefabrication, by road freight can be quickly moved to the site of the project, and the flexible disassembly, scaffolding, moves to other sites use again.In the project site, the infrastructure and engineering supporting as blocks of flexible construction and deployment pattern, reduce the cost of on-site construction period and project construction, to realize green data center construction.

Direct/indirect multi-mode natural refrigeration.
In the region, when weather conditions permit when outdoor temperature is lower than indoor, commonly used to recommend ways to direct air to natural cooling, low initial investment, the system of this scheme is simple and natural areas in energy saving effect is obvious.But fresh air directly into the room, the temperature and humidity are difficult to control, leading to a large number of condensed water and humidifying energy consumption is too large, dedusting effect is poor, unable to divide the problem such as the chemical pollutants such as sulphur and phosphide.
In order to solve the above problems, can introduce indirect wind heat natural wind cooling scheme, indirect natural cooling is to use an air - air heat exchanger, the outdoor low temperature high temperature air through the heat exchanger is passed to the indoor air, avoid the pollution caused by external fresh air directly into the room.At the same time, the air - air heat transfer efficiency is reduced, and the size of heat transfer equipment is affected.In order to further improve the energy-saving sex, can use indirect evaporation and natural evaporation combining direct air cooling, wind heat natural wind cooling and mechanical refrigeration and a variety of functions, in different scenarios flexible working mode choice.
Direct new wind natural cooling mode.
In the case of low outdoor temperature and good air quality in winter, outdoor air and indoor hot air can be mixed and filtered into the machine room to minimize the energy consumption of air conditioning.
Indirect wind-induced heat transfer natural cooling mode.
In the case of low outdoor temperature in winter, in order to avoid air quality problems caused by direct new wind, heat exchange between air and outdoor air in the heat exchanger is carried out.
Indirect evaporative natural cooling mode.
In the case of low outdoor temperature in spring and autumn, the air temperature in the outdoor air is not low enough, so it is necessary to supplement the cooling capacity by means of high pressure micro-fog spraying.
Indirect evaporative natural cooling + mechanical cooling mode.
Under the condition of high temperature outside in the summer, through the high pressure micro fog spray adiabatic evaporative cooling to supplement the refrigeration, such as after heat exchanger cooling indoor air temperature is still not reach the supply air temperature requirements, also need to supplement the mechanical refrigeration.
Introduction of indirect evaporative cooling scheme without compressor running mode, using the principle of evaporation heat, air and heat exchange of air, take away the room heat, can effect comparing to investigate the maximum of 16.0, mechanical compression refrigeration and air conditioning is five times, compared with the conventional water chiller refrigeration energy saving rate, annual energy saving rate > 50% by indirect evaporative cooling scheme combined with fresh air, the wind the wind directly in thermal, mechanical refrigeration function, flexible choice work patterns in different scene, improve the overall room energy efficiency.
New energy and uninterruptible power supply connected to direct supply and distribution.
The data center has always been a big energy user, so many tech giants are experimenting with new energy and application technologies.In sunny cities, solar energy is the most widely used green new energy.Solar photovoltaic power generation system is composed of polycrystalline silicon components, in order to save the installation site, can be installed on the top of the modular data center, all component horizontal layout, stents with different Angle will reconcile spacing adjustable function, overall stent is simple, installation fast.
The heavy construction of the data center is the malady of most projects.Operation and maintenance plays an important role in energy saving and reliability in the long running life cycle of data center.In order to reduce the artificial error, to manually and de-paper, the remote intelligent monitoring scheme can be adopted to realize the following functions:
Modularization, intelligence, rapid expansion, flexible strain and green energy saving are always the main themes and spirits that lead the change of data center.Based on the existing modular data center, this paper proposes a new generation modular data center based on MDC+ to build green energy saving, and proposes several innovative technologies to improve energy efficiency.Through IT and form a complete set of modular product design (infrastructure, engineering), direct/indirect mode more natural cooling refrigeration technology, energy and uninterrupted power supply grid with straight mains power supply technology and intelligent control technology of remote visualization is expected to achieve global PUE in 1.5 the following, as a new generation of modular data center infrastructure construction to provide the reference.
