Good planning means efficient cooling
Free Cooling with ambient air
Economical precision air-conditioning systems also make use of cool ambient air for indirect cooling of the data centre. Modern control electronics only switch on energy-intensive compressor cooling when really necessary. They continuously monitor the climate in the data centre and select the optimum operating mode in no time.
New buildings without compromise
Energy efficiency is a question of planning. In new buildings, you can design the air-conditioning system to the specific requirements of the room and computing equipment with particular precision. Many possible systems exist, but only one solution will supply optimum energy efficiency for you. We will be glad to help you choose the right one.
Spot-on cooling with water
Where high-powered computers produce hotspots, chilled water goes to the heart of the problem and dissipates the heat. Liquid cooled server racks work especially efficiently in these cases. All liquid-bearing parts are strictly separated from the electronics.
Cool air guided with precision
To ensure that the cooled air gets to where it is needed, careful planning of the air conduction is part of every good climate control plan. Hot and cold aisles, raised floors and cover panels convey the cooled air to the computer with precision. Particularly efficient systems make use of closed air circuits, for example, which feed the waste heat from the server racks directly back to the air-conditioning unit via closed air ducts.
Precision air-conditioning systems are designed for efficient continuous operation in data centres and telecommunications systems. The sensible cooling capacity of precision air-conditioning systems is considerably higher than in conventional room air-conditioning units – which means that more than 95 % of the energy is used for cooling the room. The air is circulated three times faster, the temperature and humidity are maintained with the utmost accuracy
Computers are replaced every 4 years at the latest, air-conditioning systems have a considerably longer life. So when planning your new building, leave space for additional pipes, connections, interfaces and installation sites for future expansion. This is the only way to ensure that your computers and air-conditioning system can work together efficiently and grow together far into the future.
Invest in Free Cooling. This especially economical cooling system functions at moderate ambient temperatures of up to 20 °C. Free Cooling does not need an energy-intensive compressor – it makes use of the natural drop in temperature between cool ambient air and hot exhaust air from the data centre.
Running cooling compressors and fans in the air-conditioning system is particularly energy intensive. Electronic control improves response in changing load conditions, while additional cooling with Indirect Free Cooling keeps compressor running times to a minimum
For your data centre, choose heatinsulated rooms without direct sunlight, ideally without windows, on the side of the building facing away from the sun. Examine the possibility of heat recovery – for heating offices, for example, or industrial water.
