Cold Aisle Containment Systems

Cold Aisle Containment Systems utilise chillers and / or free air cooling systems to bring cold air to the front of the cabinet door via an under floor ducting system. Ideally suited to green field sites, these containment systems dramatically reduce the cost of cooling the data centre. Typically, the cabinets are arranged into aisles, and are positioned with the front doors of the cabinets facing each other. A roof is placed over the top of the aisle and doors are added to each end to trap the cold air but still provide access. The cool air is forced under the floor and brought up through vented tiles into the aisle, where the perforated steel doors of the cabinets allow the air to be drawn into the front. The active equipment within the cabinet will draw the cool air in and across its component boards, and the resultant hot air is expelled out through the rear of the cabinet into the data centre. Since the ambient air within the data centre is not the air being used to cool the cabinets, it doesn’t matter that the temperature is much higher. The result is a cost effective way to cool the equipment only, rather than waste vast amounts of energy cooling the entire data centre room.


Hot Aisle Containment Systems

Providing the perfect containment solution for existing data centres, hot aisle containment can easily be installed in existing data centers, since the required access is above the cabinet. By placing aisles of cabinets back to back with a gap of approximately 1.5 metres, it is possible to place a door at each end and a roof over the top to capture all the hot air expelled from the rear of the cabinets. This air is extracted from the containment room and either pumped outside, or elsewhere to provide Sensible Heat to other parts of the building such as the offices. No under floor ducting is required, allowing for easy access and minimal disruption during installation. The ambient temperature within the data centre becomes a comfortable temperature at around 22°C or so, which also provides a very useful bi-product – if the hot air extraction should fail, the temperature will increase very slowly, since the ambient room temperature is cool enough to keep components functioning correctly. This provides an extra level of resiliency to the data centre and allows ample time to respond to the failure.
