The Ideal Server Temperature

Cooling - Energy-Efficient and Well Planned

 
 

German data centers used more than 12,400,000,000 kWh of power in 2016 alone. Cooling and air-conditioning have become the most crucial cost object of the DC-infrastructure. In order to cool the IT-systems, the air conditioning in a data center is running around the clock. However, up to 90 % of the energy cost can be saved with energetically optimized systems compared to conventional cooling. A guarantee of availability is just as relevant. If the cooling malfunctioned, it could lead to a shutdown of the entire IT because of overheating. 

proRZ has their own division regarding cooling technology and plant construction. Our specialists plan and construct cooling products of different shape and size and give you individual advice, according to your demands. Whether it is a new building, a relocation or just optimizing your already existing cooling technology. We are happy to assist you. 

Solutions like cold/warm aisle containment, which guarantees an ideal and effective cooling of the servers, are just as well a part of our portfolio as cooling solutions for single server cabinets or Blade Servers. Due to much experience from the last years, we can realize nearly every kind of cooling technology. Our systems are planned professionally and guarantee the strict observance of all required parameters like air temperature, humidity, cleanliness class, flow pattern, nominal ventilation, etc.

Server Cooling

In order to achieve the perfect energy efficiency for server cooling, we use sensitive precision cooling technology, which can work more accurately and, hence, require less energy than room air-conditioning. Although this equipment is more expensive, it pays off quickly because it can save you up to 45 % of operational costs. 

Regarding the air distribution inside a server room, there is a lot to keep in mind. First, the room has specific requirements and the servers' heat loads demand a better air performance than comfort air-conditioning can provide at the same cooling capacity. Apart from that, a precise adjustment of temperature and humidity is necessary to make sure that the IT works properly even on full load.


In-Row-Cooling

A high power density in the server rack can lead to the cooled air not reaching every inch and the overheating of certain components as a consequence. So, if there is an output with more than 10 kW per rack, a direct cooling right at the rack is possible. In contrast to a central cooling unit for the entire room, additional compact side-cooler elements are installed between the racks which cool the IT-system specifically and blow the exhaust air out of the back of the racks. Either water-based or cryogen-based cooling solutions are possible. This is called In-Row-Cooling and does not require double floors in the data center. 


Free Cooling (FC)

The conventional cooling can also be supplemented by cold outdoor air supply in cold and moderate climate zones. Depending on the outside temperature, those Free Cooling systems can work up to 90 % more efficiently than a standard compression cooling. According to the demand, direct or indirect FC can be realized. 

Direct Free Cooling uses filtered outside air, which is conducted directly into the interior and it can be supported by a compression cooling unit if needed. Such a system can run without additional cooling for about 90 % of the year. However, temperature and humidity can vary inside the server room and not all IT-systems are designed for it. 

The indirect Free Cooling, in comparison, takes the cooling performance from the outside air by cooling liquid running through a heat exchanger on the outside and hence, cooling the air inside. Only at an outside temperature of roughly 16 °C, this system is supplemented by a conventional cooling. The cooling performance adjusts dynamically to the actual output requirement through a speed-controlled fan-steering of the heat exchanger.
