HVAC FEATURE AWARD-WINNING INDIRECT FRESH AIR FREE-COOLING AHU
Airedale International returned to this year’s DatacenterDynamics Converged held at ExCel London with an addition to its range of award-winning, energy- saving IT cooling solutions: the Aireflow indirect fresh air free-cooling adiabatic air handling unit (AHU). The AireFlow AHU offers substantial
free-cooling potential and eliminates the risk of contaminated air entering the data centre. The use of fresh air as the predominant cooling source significantly reduces operational costs for users and based on London ambient temperatures could achieve AHSRAE recommended conditions using 100% free-cooling. In contrast with direct air handling
units, indirect cooling solutions reduce the dependency on back-up mechanical cooling required to prevent contaminated ambient air permeating the data centre. This ensures there is no requirement for internal air conditioning units, therefore maximising IT footprint. The AireFlow will be available in five footprints between 100 and 440kW with two separate case sizes depending on whether roof or wall-mounted connection is required. ACIS provides a tool to manage cooling and other building services from any manufacturer in a single, integrated system across multiple
calculating live CO2 emissions and Power Usage Effectiveness (PUE). Since last year’s show Airedale has
picked up several key industry awards. Winner of the Datacentre Energy Efficiency Product of the Year and Commercial Building Services Product of the Year in the 2014 Data Centre Solutions (DCS) and H&V News awards respectively, the SmartCool SD/SN/SR dedicated chilled water (CW) precision air conditioning (PAC) system (11-233kW) provides up to 30% more cooling per kW/m2 than its nearest rival. High on the agenda for visitors to DCD
sites and communication protocols, providing 24/7 remote monitoring, optimising system operation and improving decision-making. A fully integrated Building Energy
Management System (BEMS) module will provide more advanced energy management capabilities including
Indirect solutions reduce the dependency on back-up mechanical cooling required to prevent contaminated ambient air permeating the data centre
was the TurboChill (TCC) & TurboChill FreeCool (TCF) chiller with low global warming potential (GWP) refrigerant R1234ze which has been rated by the International Panel for Climate Change (IPCC) with a 100-year GWP lower than 1, better than CO2. The TCF offers twice as much free-cooling as a centrifugal-based chiller to deliver free-cooling for up to 95% of the year (based on a 24/7 data centre with a typical room temperature of 24°C, London, UK).
