Research & Development

Successful, independent, multi-disciplinary research project from H1 Systems in cooperation with reputed domestic and foreign partners in the field of data center energy efficiency.

H1 Systems was running an independent, multidisciplinary research project, cooperating with well-recognised domestic and foreign partners on the area of energy efficiency of datacentres.
The engineering of datacentres regarding to facilitate multiple energy supplies and meet with concentrated, continuous and significant energy demand initiate a constant challenge for engineers and facility operators.
As the result of the project, this unique state-of-the-art technological know-how makes the datacentre project competitive both on domestic and international level while generates demand for designing, constructing and operational service mandates based on high-end know-how.

Our goals are positioning Hungary for a recognised and preferred place on the international market and also creating a new position for our company on this highly knowledge-based field.

As a highlight of our results in connection with the above mentioned research:

DCSim®

The other bright outcome of the project is DCSim®, an applied integrated technical and economic model integrated into a user surface which aims to run simulation with freely selected boundary conditions and the functionally most efficient mix of the datacentre technologies.

The optimal configuration minimises the loss of the IT supplies as well as the server mechanical and other consumption, and also creates the opportunity of application renewable energy resources and the recycling or sale of waste heat.

The usage of our DCLoc® interface is free of charge, but requires registration. The interface and registration can be found on our website: dcsim.hu

DCLoc®

One of our subtasks was to create a web interface with free subscription. This cutting-edge product, DCLoc® aims to evaluate Hungarian locations regarding to datacentres construction development by the parameters of various environmental features.

On the map we can filter with 35 different indicators based on Hungarian public data, so you can easily see data related to, for example, inland water areas, annual precipitation, maximal and minimal temperatures, wind speed and several other factors.

We also provide site evaluation analyses, with a different weighting logic case by case. We classify the different locations on a numeric scale, therefore, the optimal solution to meet our requirements  will be easy to define.

Extremely energy efficient data center

In our understanding, the technological mix is a certain technological know-how, which primarily aims to support in creation of a data center concept by summarizing the research results, thus its market application takes indirectly shape in higher value-added engineering services.

Based on the research results, the hypothesis of an ideal data center technological line can be defined which can efficiently utilize the hidden potentials in energy storing. The site of the data center constructed in this way is bound to a natural or artificial thermal storage which operates with compressor-based peak-time cooling system with an additional adiabatic cooling, in an environment of favorable peak-and-valley-time electronic tariff system. The cooling system is able to utilize the capacity of the thermal storage for efficiency improvement as well as to provide heat supply to balance the downtime of the cooling equipment. It uses own smart network solutions and belongs to smart power and heat supplying networks. In cooperation with these, it utilizes the external material and energy flows and it contributes to the reduction of global pollutant emission by generating profit with local biomass- and solar-panel-based energy production.

During the research phase of the project, in order to achieve the goals drawn up above, we have defined the technological elements which are significant in respect of the investigation of data center energy interdependences and the general energy flow schematics, as well.

IT module: it is not showed on the figure, since usually it is made –up from the IT object itself. The reason to understand it as a module is that there is an opportunity to consider it together with the PDU object, depending on the location of energy consumption measuring point.

DS module: namely Direct Service module. These objects are directly responsible for the operation of IT objects and the module itself.

IS module: namely Indirect Service module. These objects are primarily responsible for the maintenance of the facility, such as reception or outdoor lighting.

JNT module: it models the other (Joint) services, as a simple energy consumer. In the further phase of our research we also plan to expand the scheme with heat consumption that can be practically the waste heat.

TRF module: this module contains the initial energy transformation and distribution units (Transformation). Their task is basic energy distribution and transformation if needed.

GEN module: namely Generation module, which contains the on-site energy production and energy transformation tools, including the „BUY” objects on the outlets of the model which are responsible for registering bought energy resources.

The construction of especially energy-efficient data center infrastructures has logically bound methodology to warrant the optimization of the facility operation by meeting technical, economic and environmental objective functions. One of the most important results of the research was the creation of this methodology, and this forms the basis for dissemination, the further utilization of the results. The methodology is based on the network of casual relationships discovered during the time frame of the project and its utilization takes shape through the direction of planning way of thinking.

To examine stochastic processes empirically (weather, IT-room load changes, etc.), a data center prototype will be also constructed. The main of this is to test the predictive simulation result of DC_SIM compared with real measured data, namely validation, including the experimental development of DCTech’s data center technology innovation elements, such as:

  • Evaporative cooling with utilization of rain water,
  • concentrated energy storing,
  • Direct integration of renewable energy resources,
  • Impact evaluation of modifications in IDT infrastructure,
  • Development of efficiency function algorithm.

One of the most innovative parts of the system is a 3,5 m3 tank, containing approx. 3,3 dl, nearly globular plastic bottles filled with 17-19oC phase changing paraffin material. This way you can supply your system with the 15oC cooling water and receive back the supplied cooling energy in the form of 20oC temperature cooling water.
