More and more computing power in less and less space and changing technological standards - new server generations require new cooling concepts for information and telecommunications technology (ICT). Weiss Technik offers a wide range of solutions that are precisely tailored to meet the specific requirements and which operate economically and safely even under extreme conditions.
Two factors are crucial when it comes to air-conditioning data centres: operational reliability and economic efficiency. Reliable cooling is essential for the security of data and hardware, as overheating is one of the most common causes of server failures. In addition, it needs to be operated with the lowest possible energy and cost input in order to remain economically viable. However, since individual circumstances must be taken into account, there is no single optimal climate solution. Decisive criteria are, for example:
Data centres are currently cooled almost everywhere by air-circulating systems that absorb the heat in the server room and dissipate it via a cooling medium, e.g. water or refrigerant. Depending on the requirements and structural conditions, different devices are used:
Precision air-conditioning units are specially designed to meet the requirements of data centres: they accurately control the supply air temperature and run continuously in an energy-efficient manner. If necessary, they can react to unforeseen temperature fluctuations thanks to intelligent control. Depending on the structural conditions, there are different types of units:
Our unique cooling wall system Vindur CoolW@ll is a real innovation in the field of IT air conditioning. The partition wall between the IT room and the service corridor is used for cooling through the use of large-area, water-flow heat exchanger modules. In doing so, you easily gain more space in the data centre and can completely do without recirculation air conditioning units.
The heat exchanger filter modules in the wall and the underfloor fans in the raised floor provide the most efficient chilled water cooled room climate system for data centres. Thanks to the larger heat exchanger surfaces and the optimal airflow, very high heat loads can be dissipated extremely efficiently. There are no energy losses due to turbulence or constriction and internal pressure losses are greatly reduced.
The advantages at a glance:
Row-based cooling units are best suited for small and medium ICT rooms that do not have raised floors or partitioned infrastructure areas. They are installed in a space-saving manner between two server racks directly in the server room and emit cold air to the front. The air is drawn in from the surrounding racks, where it absorbs the waste heat from the servers. The resulting warm air is absorbed again by the cooling unit on the rear side of the rack row. This saves costly air routing in separate ducts or in raised floors.
