ACR was invited to supply temporary data centre cooling rental whilst a major CCU replacement programme was carried-out.
Of critical importance, was to supply a reliable temporary system to supply chilled air for spot cooling around the work areas. In addition, this cooling would need to follow the works as they progressed.
Because of the space restrictions in the centre, no equipment was to be placed inside. This required some lateral thinking before a suitable solution was proposed.
Two temporary AHU’s were supplied along with chillers for a total of 300Kw’s of cooling capacity. Fresh air was supplied to the building through flexible 500mm ducts.
To boost cooling when ambient temperatures rose and free cooling was not sufficient, water chillers were installed. The conditioned air was ducted into and under the floor plenums and onto the work areas.
Working on a rolling programme, all the data centres CCU’s were replaced. To facilitate this, the duct-work was moved to suite the ongoing cooling requirements of the programme. All in all, a project that we stayed close to to support.
This AHU is rated at 200kw’s. A 400kw chiller was supplied with this to boost the ambient air cooling capacity. A 6 degree delta T was was achieved across the AHU in this way. The AHU will supply air at a rate of 4m3/s.
The second AHU system supplying the rear of the building. Air was being sent in at 6.5 degrees- an 8 degree delta T over ambient achieved by mechanical cooling. This is a 100kw AHU, supplying air at a volume of 4 m3/s.
Overall, this data centre cooling rental system proved to be a very effective and efficient. Importantly, all the customers requirements were met, meaning that, full reliable operation of the data centre was possible during the replacement works.
The key to the success of this project was the supply of large amounts of chilled air at high velocity to the work areas- very effective data centre cooling rental.
It’s safe to say this ranks among one of our most challenging projects. Albeit, not in terms of scale, but more from a controls point of view. The client’s plant was to undergo a replacement programme.
To provide emergency server room cooling during un-planned repair works. Critically, the area required fast installation of a cooling system to maintain seem-less operation.
To install a reliable temporary computer suite cooling system. This was a very interesting and sensitive project that required a careful approach and much planning.
