Aircon Services were recently approached to find a more efficient cooling solution for the Main Data Room at ‘Travelport’ Head Office, Langley, Berkshire.
Their data room was being cooled using 3No. Liebert L99UA down flow close control computer room units and their corresponding Leibert HBE99 air cooled condensing units offering a combined Sensible cooling capacity of 255kW spread over 6No refrigerant circuits. The condensing units were located within a purpose built compound at ground level but across a service road. With the interconnecting refrigeration pipe work running through a trench below this service road. Over time the condensing units had become badly corroded resulting in inefficiency through lack of heat transfer. A new solution was required.
