Energy Savings in the Data Center—in a Sustainable Way
Data centers consume an ever-increasing proportion of the electricity produced worldwide -- reaching 4% already today.
Cooling with conventional technologies contributes considerably to this high consumption. This is exactly where FAHRENHEIT cooling systems come in. Computer power is converted into waste heat. It is precisely this readily available thermal energy that the adsorption technology uses for cooling instead of expensive electricity.
Optionally, adsorption cooling can be driven by external heat sources, such as a combined heat and power plant or solar-thermal collectors.
Cool Computing: Cooling Servers with their own Waste Heat
By means of heat re-use and adsorption cooling, operators of data centers and server rooms can save considerably: Both in terms of electricity and CO2 emissions.
LRZ LEIBNIZ SUPERCOMPUTING CENTRE
COOLING SERVERS WITH THEIR OWN HEAT: SUPERMUC-NG
In 2018, LRZ's supercomputing facilities received a significant enhancement by adding a next-generation computer with around 20 Petaflops, sdes Leibniz Rechenzentrums wurden 2018 um einen Rechner der neuesten Generation mit ca. 20 Petaflops ausgebaut: SuperMUC-NG entered the TOP500 list of the fastest computers in the world in 8th place at its launch in November 2018. The Lenovo computer's approx. 13,000 processors are cooled using hot water.
This hot water is being turned into more than 600 kW of cooling capacity by a custom-designed FAHRENHEIT adsorption chiller, one of the most powerful ones in the world. The cooling capacity is used to cool networking and storage components.
LRZ LEIBNIZ SUPERCOMPUTING CENTRE
COOLING SERVERS WITH THEIR OWN HEAT: COOLMUC
The LRZ is the IT service provider for all Munich universities as well as a growing number of research organisations throughout Bavaria. It provides more than 100,000 users with IT services.
In addition, it operates one of the largest supercomputers in the world. With the use of the FAHRENHEIT adsorption chiller units, for the first time, the waste heat from the computer can be used specifically for cooling.
As a result, electricity costs for cooling have been significantly reduced. At the same time, the measure contributes to sharpening LRZ's profile as an innovative and responsible research data center.
FLUE GAS WASTE HEAT FOR IT COOLING: WILHELM KÄCHELE GMBH
The Wilhelm Kächele GmbH manufactures and develops rubber parts and rubber composite parts for a wide variety of industries. The focus is on dynamic properties, chemical and thermal resistance, installation space, the non-detachable connection between rubber and solid components made of metal or various plastics, and the reliability of the products.
In 2016, Wilhelm Kächele commissioned FAHRENHEIT to develop, plan and implement a solution for the sensible use of process waste heat for cooling purposes.
During the production process, flue gas waste heat, which is produced during the production of rubber, is converted by FAHRENHEIT’s adsorption technology into environmentally friendly and CO2-saving refrigeration. The adsorption chiller eCoo 2.0 I 10IPS generates 14 kW of cooling capacity, which is used to cool a control room. The company, therefore, has an economical as well as ecological solution – hot exhaust air creates cost-neutral cooling for the electrical rooms.
CHP: Cooling data center of Stadtwerke Schönebeck
Stadtwerke Schönebeck wins the "German Data Center Award 2016" with FAHRENHEIT
adsorption technology. The project objective was to facilitate the expansion and reconstruction
of the data center and the construction of a new heating center with CHP and the construction
of a new server cooling system with adsorption chiller.
The municipal utilities have decided in favor of a FAHRENHEIT eCoo 2.0, which makes the operation and cooling of a data center ecologically sensible in combination with the combined heat and power plant using combined heat and power.
oe Oeding Print
Cogeneration plant: oeding print
For oeding, the issue of sustainability is the foundation for future viability. Through the consistent use of tested and available technologies, oeding print created an efficient production and management building that meets all the criteria for a modern production facility and complies with the high demands regarding resource efficiency and operating cost optimization at the same time.
Responsibility towards the environment and fellow human beings is also very important to the printing company. Accordingly, the company wanted to develop an energy concept that limits greenhouse gas emissions and further environmental damage and that uses resources in an environmentally-friendly way.
The result is impressive: An eco-building with movement sensors to optimize the lighting and heating and which produces the energy needed to heat and operate it itself. This solution is based on the three key pillars: Energy efficiency, energy recycling and energy generation. Hidden behind these three simple points are an extensive amount of measures that use the most modern technologies and procedures.
For an effective energy recycling, oeding print uses technologies such as waste heat recovery from production processes, compressed air generation and combined heat and power generation, and they also store the generated waste heat in high and low-temperature tanks. This is then used to heat storage and sluice areas, to cool the IT centre or to heat water.
The renewable energy is generated with a photovoltaic system, a combined heat and power generation with the building’s own cogeneration plant, as well as an adsorption chiller from FAHRENHEIT.
PROCESS COOLING WITH COMPRESSOR WASTE HEAT: GUMMIWERK KRAIBURG
The specialist for rubber floor coverings is a leading manufacturer that relies on sustainable raw materials and environmentally friendly production: high-quality raw materials, especially old car tires, are optimally recycled through ingenious manufacturing processes.
There is hardly any waste in the production of KRAIBURG rubber flooring. The process makes it possible to recycle tailor-made products back into the recycling cycle. Another important contribution was made in 2016, together with FAHRENHEIT, namely the saving of electricity and the reduction of CO2 emissions.
The task of the FAHRENHEIT adsorption refrigeration plant is to cool a switching and server room with 72 kW waste heat from the condensate of a steam process as efficiently as possible. A highly efficient eCoo 2.0 | 30 IPS adsorption system has been implemented, which constantly reduces the temperature in the control room with 37 kW cooling capacity to 18 ° C. Thus, the switching and server room can be cooled by adsorption cooling for a large part of the runtime almost cost-neutral.
FERNWÄRME: IEP PULLACH GEOTHERMIE
The IEP (Innovative Energy for the Pullach GmbH) is a 100 percent subsidiary of the community Pullach in the Isar Valley. In cooperation with FAHRENHEIT, the head office of DJE Kapital AG has been realized with a highly efficient adsorption cooling system eCoo 2.0 for cooling the server room and the office space above the floor in the cold contracting process.
In addition to the perfectly calculable costs of cooling by billing per kWh without capital commitment and maintenance costs, the environmental aspects were also decisive for asset managers. The CO2-neutral heating and cooling system not only serves your own green conscience, but also shows to the outside that sustainability is important to the company in several respects. This is not always the cheapest, but overall very well the cheapest solution.
The new building and the expansion of the DJE Kapital AG headquarters are now up and running, and a new edition of the adsorption technology from FAHRENHEIT has been chosen. (Implementation 2019/2020)
